Abstract Kinglet Calyptura Calyptura cristata is one of the great enigmas of the South American avifauna. Endemic to an apparently tiny area of south-eastern Brazil, in the Atlantic Forest biome, the species was not definitely seen between sometime in the second third of the 1800s and 1996, when it was briefly rediscovered in submontane forest north-west of Rio de Janeiro. Since then, C. cristata has been reported several times, but without documentation and always by single observers. It is currently considered Critically Endangered by BirdLife International, and various authors have speculated that the species might already be extinct. Given the extreme paucity of knowledge of this species, we provide a complete inventory of museum material for Kinglet Calyptura - more than 100 specimens are listed, the majority held in European collections, almost doubling previous estimates made in the literature. Several are held in relatively small institutions, thereby suggesting that yet more specimens might still be identified or found. In addition, with the benefit of this large sample of material, we discuss morphological variation in the species and we hypothesise particularly about the appearance of male, female and juvenile plumages.

Abstract The Little Chachalaca (Ortalis motmot) is a widely distributed species in the Amazon basin, typically found in riverine habitats. There are two disjunct populations: the northern O. m. motmot and the southern O. m. ruficeps (known as Chestnut-headed Chachalaca). Here we performed a vocal, morphological and plumage comparison between these two taxa. Birds present differences in tail coloration but are otherwise undiagnosable in terms of plumage. Ortalis m. ruficeps is, however, markedly smaller and lighter than O. m. motmot, with no overlap in size or weight. We also found vocal differences between O. m. motmot and O. m. ruficeps, no overlap in geographic distributions and no signs of hybridization across its range. Based on the available data, Ortalis m. ruficeps thus must be considered a valid species, endemic to Brazil.

Abstract Montane and submontane forest patches in the state of Bahia, Brazil, are among the few large and preserved Atlantic Forests remnants. They are strongholds of an almost complete elevational gradient, which harbor both lowland and highland bird taxa. Despite being considered a biodiversity hotspot, few ornithologists have surveyed these forests, especially along elevational gradients. Here we compile bird records acquired from systematic surveys and random observations carried out since the 1980s in a 7,500 ha private protected area: Serra Bonita private reserve. We recorded 368 species, of which 143 are Atlantic Forest endemic taxa. Some 16 and 13 species are threatened at the global and national levels, respectively. If one accounts for subspecies, the number of Brazilian threatened taxa raises to 21. Species composition differs between lower and higher elevations, in which case lowlands harbor Amazonia-related taxa, whereas highlands are the home of Atlantic Forest-related taxa.

Abstract We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data.

OBJETIVOS: avaliar o grau de aderências pélvicas em função do tempo e da utilização de diferentes substâncias empregadas na sua profilaxia. MATERIAL E MÉTODOS: estudo prospectivo com 120 ratas Wistar, albinas, virgens, 3 a 4 meses de idade, pesando aproximadamente 250 gramas, divididas aleatoriamente em 10 grupos de 12 animais cada: controle, sem lesão; lesões e sem tratamento; lesões + solução fisiológica 0,9%; lesões + Ringer-lactato; lesões + dextrano 70 a 32%; lesões + Ringer-lactato/heparina; lesões + Ringer-lactato/dexametasona; lesões + Ringer-lactato/hidrocortisona/dexametasona/ampicilina; lesões + Ringer-lactato/albumina e lesões + carboximetilcelulose 1%. Após anestesiados os animais, realizaram-se dois tipos de lesões nos cornos uterinos (escarificação e eletrocauterização), seguidos de tratamento profilático intraperitoneal com as soluções citadas. No 7º, 14º e 28º dia pós-operatório, momentos M1, M2 e M3, respectivamente, avaliaram-se quatro ratas de cada grupo quanto à presença de aderências. Os métodos empregados na quantificação das aderências encontradas basearam-se na classificação de Cohen, com escores variando de 0 a 4+ de acordo com a quantidade, características e localização das aderências. Foram usadas provas paramétricas para análise da variância e Kruskal-Wallis. RESULTADOS: os melhores tratamentos para prevenção de aderência pélvica em ratas foram: Ringer-lactato/dexametasona (predomínio do escore 1+), dextrano 70 a 32% (predomínio do escore 2+) e Ringer-lactato/hidrocortisona/dexametasona/ampicilina (predomínio do escore 2+). O período pós-operatório, representado pelo momento M3, e a técnica cirúrgica, predominantemente com escore 0, influíram na adesiólise e manutenção de aderências pélvicas em ratas. CONCLUSÕES: a prevenção de aderências pélvicas em ratas inicia-se no processo cirúrgico de baixo dano tecidual; o uso de substâncias profiláticas (soluções) tem eficácia variada, sendo que algumas mostraram-se mais eficazes que outras.

PURPOSE: to evaluate the degree of pelvic adhesions in function of time and the different substances used in its prophylaxis. MATERIAL AND METHODS: prospective study with 120 female, albino, virgin Wistar rats, 3 to 4 months of age, weighing approximately 250 g, randomly divided into 10 groups of 12 animals each: control, without lesion; lesions and without treatment; lesions + 0.9% physiologic saline, lesions + Ringer lactate; lesions + 32% dextran 70; lesions + Ringer lactate/heparin; lesions + Ringer lactate/dexamethasone; lesions + Ringer lactate/hydrocortisone/dexamethasone/ampicillin; lesions + Ringer lactate/albumin, and lesions + 1% carboxymethylcellulose. The animals were anesthetized and two types of lesions (scarification and electrocauterization) were performed in the uterine horns, followed by treatment with the solutions, intraperitoneally, to prevent pelvic adhesions. On the 7th, 14th and 28th postoperative days, moments M1, M2 and M3, respectively, the presence of adhesions was evaluated in 4 rats of each group. The methods applied to the quantification of the adhesions were based on Cohen's classification, with scores varying from 0 to 4+ according to the amount, characteristics and location of the adhesions. Statistical analysis was performed by parametric tests for analysis of variance and the Kruskal-Wallis test. RESULTS: the best treatments for prevention of pelvic adhesions in female rats were Ringer lactate/dexamethasone (score 1+ prevalence), 32% dextran 70 to (score 2+ prevalence) and Ringer lactate/hydrocortisone/dexamethasone/ampicillin (score 2+ prevalence). The postoperative period, represented by moment M3, and the surgical technique, predominantly with score 0, influenced adhesiolysis and maintenance of pelvic adhesions in female rats. CONCLUSIONS: the prevention of pelvic adhesions in female rats begins with the surgical process at a smaller extent of tissue damage. The use of prophylactic substances (solutions) had a varied effectiveness, since some were more efficient than others.
