ABSTRACT. Morphomctric data of undcrstory birds from castem Mato Grosso do Sul Stllte, Brazil. Data on body l11ass and l11easurel11ents or externai characteristics (Iength, width and height orbill ; tarsus, tail, wing and totallengths) ror live birds rrol11 eastern Mato Grosso do Sul State, Central Brazil are reported. Mcan, standard deviation and l11inil11ul11 and l11axil11ul11 values are show for 95 species. KEY WORDS. Brazil, cerrado, morphometrics Dados morfométricos ainda são pouco conhecidos de uma maneira geral , particularmente para aves neotropicais. Segundo WrNKER (1998), não há ainda literatura que padronize e discuta apropriadamente os métodos de obtenção de dados morfométricos em aves.Existe também pouca discussão sobre as possíveis fontes de variação nas características morfométricas e sobre a importância de se obter estes dados. Quando em isolamento geográfico, diferenças morfológicas na mesma espécie podem ocorrer em períodos de tempo relativamente curtos (CLEGG et aI. 1998). Raças geográficas, idade, sexo e o tempo podem ser fontes de variações (BIERREGAARD 1988; COUNS1LMAN et ar 1994).Para aves brasi leiras, alguns trabalhos recentes têm contemplado este assunto.

ABSTRACT. Bird-window collisions are a dramatic cause of bird mortality globally. In Latin America, statistics are generally very scarce and/or inaccessible so the frequency of such incidents is still poorly understood. Nevertheless, civilians have applied preventive methods (e.g. adhesive bird-of-prey decals) sparsely but, to our knowledge, no study has evaluated their effectiveness in Brazil. Here, we estimated the mortality rate of bird-window collisions and tested the effectiveness of bird-of-prey decals at preventing such accidents. We undertook daily searches for bird carcasses, presumably resulting from window collisions, near all buildings on a university campus over seven months. Adhesive bird-of-prey decals were then applied to the two buildings with the highest mortality rates and surveys continued for over 12 more months. The mortality rates before and after the application of decals and between seasons were then compared using Friedman test. We recorded 36 collisions, 29 around the two buildings with the highest collision rates 19 prior and 10 after our intervention with associated collision rates of 0.08 and 0.04 collisions/day. Although mortality was reduced by almost half, this difference was not statistically significant. The Blue-black grassquit, Volatinia jacarina (Linnaeus, 1766), and Ruddy ground dove, Columbina talpacoti (Temminck, 1810) suffered the highest number of collisions, followed by the Rufous-collared sparrow, Zonotrichia capensis (P. L. Statius Müller, 1776). Our bird-of-prey decals and efforts were insufficient to prevent or dramatically reduce the number of bird-window collisions. Therefore, we recommend that different interventions be used and additional longterm studies undertaken on their efficacy.

O objetivo deste trabalho foi estudar padrões comportamentais de Molothrus bonariensis (Gmelin, 1789) em condições naturais, traçando seu etograma. As coletas de dados foram efetuadas em Seropédica, no Estado do Rio de Janeiro, através de observações naturalísticas contínuas e animal-focal, utilizando-se binóculos 10 x 50 principalmente pela manhã até às 07:00h e à tarde após as 16:00h. Foram detectadas 25 condutas, agrupadas em sete categorias comportamentais: locomoção (n = 7), manutenção (n = 5), social não-agonístico (n = 5), alimentação (n = 2), social-agonístico (n = 2), vigilância (n = 2) e sonora (n = 2).
