Resumen Registramos dos casos de leucismo en la paloma de collar Asiática (Streptopelia decaocto) en dos localidades del norte de México. Ambos individuos fueron los primeros registros de leucismo en esta especie para los estados de Nuevo León y Durango. Los dos ejemplares presentaban la mayor parte del cuerpo con plumaje blanco, patas rosadas y pico grisáceo (comparado con los individuos normales), pero mantuvieron los ojos con su color característico. Ambos individuos fueron observados solo una vez y en solitario.

Abstract We observed two cases of leucism in the Eurasian Collared-Dove (Streptopelia decaocto) in two localities of Northern Mexico. Both individuals were the first leucistic records for this species in Nuevo Leon and Durango states. The two specimens had most of the body with white plumage, pinkish legs, and grayish beak (compared to normal individuals), but maintained the characteristic color in the eyes; and were observed only once and as solitary individuals.

ABSTRACT Background: Domestic pigeons carry pathogens in their droppings, posing a potential public health problem. Methods: The phenotypic and genotypic antimicrobial resistances of Staphylococcus aureus and Enterococcus faecium in the feces of urban pigeons near hospitals with intensive care units were measured. Results: Twenty-nine samples showed Enterococcus growth, whereas one was positive for S. aureus. The S. aureus isolate was sensitive to the antibiotics tested via antibiogram, however resistance genes were identified. E. faecium isolates showed phenotypic resistance to gentamicin, erythromycin, and ciprofloxacin. Conclusions: Antimicrobial profiles harmful to health were demonstrated in bacterial pathogens isolated from the external environment of hospitals.

Resumen Presentamos nuevos aspectos de la biología reproductiva de la Yerutí Colorada Leptotila rufaxilla, de cinco nidos encontrados entre 2012 y 2014 en un fragmento de bosque de tierras bajas en el suroeste de Brasil. Los nidos con forma simple / plataforma se construyeron a una altura media de 1.90 m sobre el suelo. El tamaño de la puesta fue de dos huevos blancos y elípticos, incubados durante 15 días (basado en tres nidos). Registramos depredación en dos nidos aún en fase de incubación. El peso mínimo al nacer de los pichones fue de 10 g y los polluelos dejaron el nido con una masa media de 56 g. La tasa de crecimiento constante (K) de los pichones fue de 0.40 con una asíntota de crecimiento de 60.7 g. La tasa de supervivencia diaria, Mayfield y el éxito aparente de anidación en el período de incubación fue de 90, 20 y 56%, respectivamente, mientras que en el período de cría fueron todos de 100%. Nuestros datos y el aporte de la ciencia ciudadana mostraron que L. rufaxilla se reproduce durante el año, principalmente en la época de lluvias, tanto en el suroeste de la Amazonia como en otras regiones de ocurrencia.

Abstract We present new aspects of breeding biology of Gray-fronted Dove Leptotila rufaxilla, from five nests found between 2012 and 2014 in a lowland forest fragment in southwestern Brazil. The nests simple/platform shape were built at a mean height of 1.90 m above ground. The clutch size was two eggs white and elliptic, incubated for 15 days (based on three nests). We recorded predation in two nests still in incubation phase. Minimum hatch weight of nestlings was 10 g and young fledged with a mean mass of 56 g. The constant growth rate (K) of nestlings was 0.40 with a growth asymptote of 60.7 g. Daily survival rate, Mayfield and apparent nesting success in the incubation period was 90, 20 and 56%, respectively, while in the nestling period were all 100%. Our data and the contribution of citizen science showed that L. rufaxilla breeds over the year, mainly in the rainy season, both in southwestern Amazonia and in other regions of occurrence.

Resumo O objetivo deste estudo foi verificar a presença e a identificação espécies de parasitas hemosporídeos em pombos (Zenaida auriculata) no Brasil. Duzentos e onze pombos machos e fêmeas foram capturados em quatro regiões diferentes de Londrina, sul do Brasil. Amostra de sangue foi coletada em tubos contendo EDTA por meio de punção cardíaca, após eutanásia em câmara de CO2. Uma nested PCR com alvo no gene mitocondrial citocromo b (cyt b) de Haemoproteus spp./Plasmodium spp. foi realizada, seguida de digestão enzimática para identificar o gênero. A árvore filogenética foi construída para determinar a relação com outras espécies. Das 211 pombas, 209 (99,05%) foram positivas para Haemoproteus spp./Plasmodium spp. A análise RFLP demonstrou que 72,72% (152/209) das pombas foram positivas somente para Haemoproteus spp.; 6,22% (13/209) foram positivas somente para Plasmodium e 21,05% (44/209) das pombas tiveram infecções mistas. A análise genética mostrou quatro amostras homólogas com H. multipigmentatus e uma com Plasmodium spp. Este é o primeiro estudo molecular de hemoparasitas em pombos no Brasil. E é também a primeira descrição da infecção por H. multipigmentatus e Plasmodium spp. em pombos Z. auriculata no Brasil.

Abstract The aim of this study was to verify the presence and identify the species of haemosporidian parasites in eared doves (Zenaida auriculata) in Brazil. Two hundred and eleven male and female eared doves were trap-captured in four different regions of Londrina city, in southern Brazil. Whole blood was collected in EDTA tubes through heart puncture after euthanasia in a CO2 chamber. A nested PCR targeting the mitochondrial cytochrome b gene (cyt b) of Haemoproteus spp./Plasmodium spp. was performed, followed by an enzymatic digestion to identify the genus. Phylogenetic trees were constructed to determine the closely related species. Out of 211 eared doves, 209 (99.05%) were positive for Haemoproteus spp. and/or Plasmodium spp. RFLP analysis showed that 72.72% (152/209) of eared doves were positive only for Haemoproteus spp., 6.22% (13/209) were positive only for Plasmodium spp., and 21.05% (44/209) of eared doves had mixed infections. Genetic analysis found four samples that were homologous with Haemoproteus multipigmentatus and one that was homologous with Plasmodium sp. This is the first molecular study of hemoparasites from eared doves in Brazil, and it is also the first description of H. multipigmentatus and Plasmodium spp. infection in eared doves in Brazil.

Resumen Los factores biomecánicos, el comportamiento e historia natural de las especies pueden influenciar la forma y dimensión del ala en las aves. Por lo tanto, la morfología de las alas de cada especie podría estar adaptada al ambiente en el que habitan. En palomas (familia Columbidae) existe un gradiente de especies que tienden a volar mucho y otras que vuelan muy poco. El objetivo de esta investigación es determinar si la forma de las alas de seis especies de palomas se asocia con su capacidad de vuelo. Predecimos que las especies Patagioenas flavirostris y P. nigrirostris que tienden a volar largas distancias presentan alas relativamente largas y puntiagudas; mientras que Geotrygon montana que se desplaza principalmente caminando presenta alas relativamente anchas y redondeadas. Especies con capacidad de vuelo intermedio (Leptotila verreauxi, L. cassini y Zenaida asiatica) van a presentar alas con características intermedias. Estimamos la carga alar, proporción de la forma, conicidad alar, largo relativo y el área alar promedio para cada especie. Realizamos un análisis discriminante para determinar cuál combinación de variables explica mejor la diferencia morfológica de las alas entre las seis especies y probamos que tan robusto es este modelo mediante una prueba binomial. El modelo clasificó correctamente el 57 % de los individuos en su propia especie. Por lo tanto, encontramos que el tipo de desplazamiento predominante en cada una de las seis especies de Columbidae analizadas, se asocia con la morfología alar: alas adaptadas para vuelos en zonas abiertas en P. flavirostris y P. nigrirostris, alas adaptadas para vuelos muy maniobrables en hábitats densos en G. montana, y alas con características intermedias en L. verreauxi, L. cassini y Z. asiatica.

Abstract Biomechanics, behavior, and natural history influence wing dimension and shape. Wing design often correlates with features of the habitat in which each species is found. Doves and pigeons (Columbidae family) range from long-distance fliers (e.g., canopy and open area species) to very short-distance fliers (e.g., species adapted to dense understory forests) and such variation makes this group fit to test the association between flying habits and wing morphology. Our objective in this study is to determine whether the wing morphology (shape and dimensions) of six dove species is associated to their flying capability. We predict that the long-distance fliers Patagioenas flavirostris and P. nigrirostris will have long and sharp wings; while the very short-distance flier Geotrygon montana will have broad and rounded wings. Other species (e.g., Leptotila verreauxi, L. cassini and Zenaida asiatica) whose flying capability fits in between these two will have wings with intermediate morphological features. We measured the wing disc loading, shape ratio, the ratio of mean to maximum wing chord, relative wing length, and wing area for each species. We conducted a discriminant function analysis to compare which variables explain better the differences in wing morphology across the six species, and used a binomial test to evaluate the power of the model. The model correctly classified 57 % of individuals within their own species. The flying capability is associated with the wing morphology of the six Columbidae species; with a wing design for long-distance fliers in P. flavirostris and P. nigrirostris, wing design for maneuvering in dense habitats in G. montana, and wings with an intermediate design in L. verreauxi, L. cassini and Z. asiatica.

En el presente trabajo se da a conocer el avistamiento de un individuo de la paloma picazuró, Patagioenas picazuro en la Reserva Ecológica Taricaya en la zona de amortiguamiento de la Reserva Nacional Tambopata a 26 kilómetros al noreste de la ciudad de Puerto Maldonado en el margen derecho del río Madre de Dios, provincia de Tambopata, departamento de Madre de Dios. Esta observación corresponde al primer registro confirmado para Perú como una especie errante. Es probable que la expansión de esta especie se deba a la deforestación e incremento de zonas de cultivo en la zona.

In this note, I report an observation of one individual of Picazuro Pigeon, Patagioenas picazuro on the right bank of the Madre de Dios River in the Taricaya Ecological Reserve, 26 km northeast of Puerto Maldonado city, province of Tambopata, department of Madre de Dios. This observation is the first confirmed record of P. picazuro for Peru. The presence of P. picazuro in Peru could be due to deforestation and an increase of croplands in the study area.

Abstract An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an important role in chromosomal instability, and therefore in chromosomal rearrangements, little is known about their distribution and amount in avian genomes. The aim of this study was to analyze the distribution of 11 distinct microsatellite sequences, as well as clusters of 18S rDNA, in nine different Columbidae species, correlating their distribution with the occurrence of chromosomal rearrangements. We found 2n values ranging from 76 to 86 and nine out of 11 microsatellite sequences showed distinct hybridization signals among the analyzed species. The accumulation of microsatellite repeats was found preferentially in the centromeric region of macro and microchromosomes, and in the W chromosome. Additionally, pair 2 showed the accumulation of several microsatellites in different combinations and locations in the distinct species, suggesting the occurrence of intrachromosomal rearrangements, as well as a possible fission of this pair in Geotrygon species. Therefore, although birds have a smaller amount of repetitive sequences when compared to other Tetrapoda, these seem to play an important role in the karyotype evolution of these species.

Resumen En Colombia el bosque seco tropical es una de los ecosistemas más amenazados y menos conocidos del país. Se desconoce mucho cómo los procesos de transformación y fragmentación de hábitat han afectado las condiciones y supervivencia de la avifauna del bosque seco. Este trabajo evaluó la influencia de los elementos del paisaje (bosques y potreros de producción ganadera con diferentes densidades de árboles) en la diversidad de aves en la región del bosque seco tropical del Departamento de Córdoba, Colombia. El trabajo se desarrolló caracterizando la avifauna en cuatro localidades conformadas por fragmentos de bosque secundario dentro de un paisaje dominado por áreas de ganadería extensiva. Se identificaron cuatro tipos de hábitats en el paisaje según la densidad de cobertura arbórea: fragmentos de bosque secundario, potreros con alta cobertura de árboles, potreros con baja cobertura árboles y potreros sin árboles. Con el fin de evaluar la influencia de la cobertura arbórea en la diversidad de aves, se realizaron muestreos en transectos de observación durante los meses de septiembre 2011 a mayo 2012 con muestreos mensuales. Los transecto tuvieron 200 m de longitud para el conteo de aves en cada hábitat, las observaciones se hicieron en la mañana (6:00 - 9:00) y en la tarde (15:00 - 18:00). Se registraron 6 667 individuos pertenecientes a 180 especies y 48 familias de aves. Las especies más abundantes fueron: Columbina talpacoti (5.37 %), Brotogeris jugularis (5.14 %), Tyrannus melancholicus (4.81 %) y Bubulcus ibis (4.80 %). La familia con mayor abundancia fue Tyrannidae (16.4 %), seguida de Psitacidae (9.0 %) y Columbidae (8.2 %). La familia que presentó mayor número de especies fue: Tyrannidae con 28 especies, seguida de Accipitridae e Icteridae con 10 especies cada una. La mayor riqueza de especies se presentó en el hábitat de bosque secundario, seguido de los potreros con alta cobertura de árboles y potreros con baja cobertura de árboles; la menor abundancia y riqueza de especies se encontró en los potreros sin árboles, presentándose diferencias significativas entre los hábitats (Fisher, p<0.05). La diversidad de aves fue mayor en los bosques secundarios según el índice de Shannon, en contraste, la menor diversidad se encontró en los potreros sin árboles. La mayor riqueza de especies se presentó en octubre y noviembre; en el resto del período de muestreo hubo estabilidad en el número de especies e individuos registrados. Se evidenció la importancia de la presencia de árboles en áreas de ganadería extensiva, debido a que ayudan a contener una importante diversidad de especies, así como a generar conectividad con los fragmentos de bosques secundarios presentes en el paisaje ganadero.

Abstract In Colombia the tropical dry forest is one of the most threatened and least known ecosystems; these have been impacted by different transformation processes and habitat fragmentation, which have affected bird conditions and survival. This research evaluated the influence of landscape elements (forest and pastures with different tree covers) on bird diversity in the tropical dry forest of Córdoba, Colombia. The study was developed within an extensive livestock landscape to characterize the avifauna in four habitat types formed by fragments of secondary forests with different tree cover: secondary forest, pastures with high tree cover, pastures with low tree cover and only pastures. The influence of tree cover on bird diversity was evaluated with monthly samplings in 200 m long transects (per habitat), with two observation intervals (6:00 - 9:00 and 15:00-18:00), from September 2011 to May 2012. A total of 6 667 individuals belonging to 180 species and 48 families of birds were registered. The most abundant species were Columbina talpacoti (5.37 %), Brotogeris jugularis (5.14 %), Tyrannus melancholicus (4.81 %) and Bubulcus ibis (4.80 %). The most abundant family was Tyrannidae (16.4 %), followed by Psitacidae (9.0 %) and Columbidae (8.2 %). The family with the highest number of species was Tyrannidae with 28 species, followed by Accipitridae and Icteridae with 10 species each. The greatest species richness was present in the secondary forest habitat, followed by the pastures with high tree cover, and pastures with low cover. The lowest abundance and species richness was found in pastures without tree cover with significant differences between the habitats (Fisher, p <0.05). According to the Shannon index, the diversity of birds was higher in the secondary forests. In contrast, the lowest diversity was found in pastures without tree cover. The greatest species richness occurred in the months of October and November. In the rest of the sampling period, the number of recorded species and individuals showed some stability. The importance of trees presence in extensive livestock areas was evidenced because they help to contain an important diversity of bird species, and they also generate connectivity among fragments of secondary forests in the cattle landscape.

Resumo Os coccídios são protozoários parasitas frequentemente observados em amostras fecais de aves silvestres, os quais têm extrema importância para a biodiversidade, especificidade hospedeira e conservação. O presente estudo teve como objetivo identificar e quantificar as espécies de coccídios de aves silvestres capturadas em uma área fragmentada de Mata Atlântica no município de Guapimirim, Estado do Rio de Janeiro, que está localizada no entorno do Parque Nacional da Serra dos Órgãos. Foram capturadas e identificadas 101 aves. A maior prevalência e densidades foram observadas na família Columbidae (Columbiformes). Nas famílias de Passeriformes, as maiores prevalências e densidades foram de aves das famílias Thraupidae e Turdidae. A maioria das amostras positivas e com maiores densidades foram coletadas no período da tarde. Foram identificadas onze espécies de Eimeria e Isospora. Sete dessas espécies morfologicamente identificadas não estão descritas na literatura científica e devem ser novas espécies. O presente trabalho expõe a ampla distribuição e dispersão de coccídios de aves silvestres no sudeste do Brasil e registra o município de Guapimirim, no estado do Rio de Janeiro, como uma nova localidade de parasitismo, além dos novos hospedeiros registrados.

Abstract Coccidia are protozoan parasites that are frequently observed in fecal samples from wild birds, and they are extremely important for biodiversity, host specificity and conservation. The aim of the present study was to identify and quantify the coccidian species from wild birds caught in a fragmented area of Atlantic Forest in the municipality of Guapimirim in the state of Rio de Janeiro, which is located around the Serra dos Órgãos National Park. A total of 101 birds were caught and identified. The highest prevalence and density were observed in the family Columbidae (Columbiformes). Among the families of Passeriformes, the highest prevalences and densities were of birds in the families Thraupidae and Turdidae. The majority of the positive samples and those with higher densities were collected in the afternoons. Eleven coccidian species of Isospora and Eimeria were identified. Seven of these species that were morphologically identified are undescribed in the scientific literature and are believed to be new species. The present study highlights the wide distribution and dispersion of coccidia of wild birds in southeastern Brazil, and records the municipality of Guapimirim, in the state of Rio de Janeiro, as a new locality for parasitism, along with the new hosts recorded.

Los parásitos sanguíneos son transmitidos por vectores hematófagos y pueden ocasionar impactos negativos en los hábitos del hospedador y como consecuencia, desbalances en la diversidad biológica de las especies de vida silvestre. El objetivo de este estudio fue estimar la prevalencia de hemoparásitos en aves silvestres de la zona oriental del estado Falcón, Venezuela entre 2013-2015. Para ello, se seleccionaron siete localidades, con características de pasos migratorios que presentaban vegetación fragmentada, considerando los dos períodos climáticos. Para la captura de las aves se emplearon redes de neblinas y su clasificación taxonómica se basó en los caracteres físicos en campo y en los registros fotográficos en el laboratorio. La población estudiada consistió de 797 individuos de 85 especies y 25 familias. Se tomaron muestras sanguíneas de la vena ulnar, para la posterior realización de extendidos que fueron coloreados con la solución de Giemsa. El diagnóstico parasitológico se realizó por microscopía de luz (1000x), identificándose 144 individuos positivos con una prevalencia general del 18,07%; para el género Plasmodium 9,66 %, Haemoproteus 8,66%, Trypanosoma 0,75% y microfilarias 1,00%; siendo la familia más afectada Columbidae y los individuos susceptibles fueron Thryothorus rutilus y Nemosia pileata. En esta encuesta se incluyeron 8 nuevos registros de hospedador-hemopárasito, se evidenció la periodicidad estacional, además de infecciones en aves residentes y juveniles, cuyo rango de vuelo son cortos por lo que se infiere que en las localidades en estudio están presentes los elementos de la triada epidemiologia, hospedador, vectores y parásitos.

Blood parasites are transmitted by hematophagous vectors and can cause negative impacts on host habits and as a consequence, imbalances in the biological diversity of wildlife species. The objective of this study was to estimate the prevalence of hemoparasites in wild birds of eastern Falcon state, Venezuela between 2013-2015. For this, seven localities were selected, with characteristics of migratory steps that presented fragmented vegetation, considering the two climatic periods. For the capture of the birds, mist networks were used and their taxonomic classification was based on the physical characters in the field and the photographic records in the laboratory. The study population consisted of 797 individuals from 85 species and 25 families. Blood samples were taken from the ulnar vein, for the later realization of stretches that were colored with the solution of Giemsa. The parasitological diagnosis was performed by light microscopy (1000x), identifying 144 positive individuals with a general prevalence of 18.07%; for the genus Plasmodium 9.66%, Haemoproteus 8.66%, Trypanosoma 0.75% and microfilariae 1.00%; Being the family most affected Columbidae and the susceptible individuals were Thryothorus rutilus and Nemosia pileata. In this survey, 8 new host-hemopatraase registers were included, seasonal periodicity was evidenced, as well as infections in resident and juvenile birds, whose ranges of flights are short so it is inferred that in the study sites are present the elements of The triad epidemiology, host, vectors and parasites.

METODOLOGIA: Estudio descriptivo transversal prospectivo con cuarenta palomas en seis lugares diferentes. Se evaluó plumaje para determinar ectoparásitos, hisopado coanal y cloacal, y muestra de sangre de la vena axilar. Se realizó examen directo con solución salina y yodada; técnica de flotación y tinción de Ziehl-Neelsen. El diagnóstico de hemoparásitos se efectuó mediante método de gota gruesa, coloración de Wright y tinción Hemacolor®. Se utilizó API 20e® para Enterobacterias. Se realizó estadística descriptiva y análisis de correlación entre hemoparásitos y ectoparásitos. RESULTADOS : Escherichia coli (95%), Haemoproteus spp. (73%), Columbicola columbae (64%), ooquistes compatibles con Eimeria spp. (55%), Pseudolynchia canariensis (52%), Trichomona spp. (40%), Capillaria spp. (28%), Menopon gallinae (24%), Ascaridia spp. (8%), y un caso de Enterobacter cloacae. Se identificó la presencia de Ornithonyssus bursa en nidos de algunas de las aves muestreadas. DISCUSION: Aunque se han presentado reportes de casos eventuales de ellos en personas dentro de la revisión de literatura, los microorganismos aislados tienen un bajo riesgo de transmisión en humanos; sin embargo pueden convertirse en un problema de salud pública veterinaria al ser potenciales fuentes de infección a la fauna silvestre urbana con quienes comparten albergue, fuentes de agua y alimento. CONCLUSION: El mayor porcentaje fue ooquistes compatibles con Eimeria spp (55%) y enterobacterias como E. coli (95%). Ornithonyssus bursa en las palomeras evidencia la presencia de un patógeno potencialmente zoonótico, causante de lesiones dérmicas en humanos.

OBJECTIVE: The aim of this study was to determine the presence of public health importance parasitic and enterobacterial infection in feral pigeons Columba livia in urban areas of Envigado, Colombia. Methodology: Descriptive transversal prospective study, 40 pigeons were taken from six different places in the urban areas. The feathers were evaluated to determine ectoparasitic infestation, coanal and cloacae swab, and blood from the axillar vein. Direct examination of feces with saline and iodine solution, flotation technique and Ziehl-Neelsen stain were made. Haemoparasites were diagnose with Hemacolor® and Wright stain in thin blood smears and Enterobacteriales with API 20e®. Descriptive statistics was made and a correlation analysis between haemoparasites and ectoparasites. RESULTS : Escherichia coli (95%), Haemoproteus spp. (73%), Columbicola columbae (64%), oocysts compatible with Eimeria spp. (55%), Pseudolynchia canariensis (52%), Trichomona spp. (40%), Capillaria spp. (28%), Menopon gallinae (24%), Ascaridia spp. (8%), and one case of Enterobacter cloacae. The presence of Ornithonyssus bursa was identified in some birds nest included in the study. DISCUSSION: Even there are sporadic reports about those parasites and enterobacterias in humans in literature revision; the microorganisms isolated in this study had a low risk of transmission in a person; although they can became a veterinary public health problem because their potential infection source to urban wildlife animals, which they share water, food and refuge. CONCLUSION: the most important percentage was oocysts compatible with Eimeria spp (55%) and enterobacterias like E. coli (95%). Ornithonyssus bursa in nest is the evidence of a potential zoonotic agent, responsible of dermatological lesions in humans in direct contact with them.

Objetivo: diagnosticar a presença de parasitas e enterobactérias de importância em saúde pública em populações de Columba livia em zonas urbanas do município de Envigado, Colômbia. Metodologia: estudo descritivo transversal prospectivo com 40 pombas em seis locais diferentes. Avaliou-se a plumagem a fim de determinar ectoparasitas, esfregaço das cóanas e de cloaca e amostra de sangue da veia axilar. Realizou-se um exame direto com solução salina e de iodo; técnica de flotação e coloração de Ziehl-Neelsen. O diagnóstico de hemoparasitas se fez por meio do método de gota espessa, coloração de Wright e coloração Hemacolor ®. Utilizou-se API 20e® para Enterobactérias.

Resultados : Escherichia coli (95%), Haemoproteus spp. (73%), Columbicola columbae (64%), oocistos compatíveis com Eimeria spp. (55%), Pseudolynchia canariensis (52%), Trichomona spp. (40%), Capillaria spp. (28%), Menopon gallinae (24%), Ascaridia spp. (8%), e um caso de Enterobacter cloacae. Identificou-se a presença de Ornithonyssus bursa nos ninhos de algumas das aves incluídas nas amostras. Discussão: embora se tenham encontrado relatos de casos eventuais deles em pessoas dentro da revisão da literatura, os microorganismos isolados têm um baixo risco de transmissão em humanos; porém, podem tornar-se um problema de saúde pública veterinária ao serem fontes potenciais de infecção à fauna selvagem urbana com quem eles compartilham albergue, fontes de água e alimento. Conclusão: a a maior percentagem foi de oocistos compatíveis com Eimeria spp (55%) e enterobactérias como E. coli (95%). Ornithonyssus bursa nos pombais evidencia-se a presença de um agente patogênico potencialmente zoonótico, responsável por lesões dérmicas em humanos.

Twenty seven homing pigeons (10 males and 17 females) were biometrically studied and the bilateral symmetry (right-left) level was evaluated. Analysed traits were the length of outer external rectrices, length of the wing and length of the second primary feather. The aim of the study was to check whether there is a relationship between the degree of asymmetry level and general health of the birds (expressed as a measure of body condition). Measurements showed a normal distribution and without differences according to the body condition, indicating a high degree of stable growth

Se obtuvieron medidas corporales de 10 machos y 17 hembras de palomas mensajeras adultas, con diferentes palmarés deportivos, a partir de las cuales se examinó el nivel de simetría bilateral (lado derecho e izquierdo) en la longitud de las rectrices externas, longitud del ala y longitud de la segunda primaria. La finalidad del estudio fue comprobar si existe una relación entre el grado de asimetría y estado general de salud de los animales (expresado como una medida de condición física). Los valores obtenidos no se apartaron de una distribución normal ni presentaron diferencias según condición corporal de los animales, de lo que se deduce que las aves presentan un grado estable de desarrollo
