We used a simple and objective method of determining home range size for individuals bird community in southeast Australia. The consisted 11 species, which represented nine genera, five families, diets nesting behaviors. vegetation on the 10-ha site comprises mixture eucalypt forest; dense thickets cycads, casuarinas, ti-tree; bushy grassy powerline clearing 30-m wide running length site; 1 ha swamp paperbark trees; several small dams containing various reeds; riparian environment variety different shrubs. Data were collected from 490 color-banded both sexes over seven to eight breeding seasons, between 40 966 sightings recorded per species. Species was significant predictor (26% variance), but this mainly because three species had large ranges compared remaining similar variable ranges. Breeding season (as indicated by year), sex, number pairs also factors together accounted only 4% variance. Southern Oscillation Index (a measure El Niño-Southern Oscillation, major climate factor that is related rainfall eastern Australia) not predictor. high residual variation (70%) each inherently sizes. Home sizes generally dissimilar (both lower higher) those same literature are consistent year at our study site. suggest result between-site habitat within-site microhabitat variation, therefore unexpected.

A defesa territorial é uma estratégia adotada em muitas espécies de Passeriformes para proteger recursos vitais a sobrevivência e reprodução contra membros da mesma espécie. O tamanho do território defendido varia acordo com espécie, podendo ter um similar ou menor que área vida. Em algumas espécies, tanto os machos quanto as fêmeas atuam na ativa território. choca-de-asa-vermelha (Thamnophilus torquatus), ave Subordem Tyranni encontrada extensas áreas América Sul, se caracteriza como excelente modelo estudo compreender territorialidade por apresentar boa responsividade playbacks, vocalizações específicas e, dicromatismo sexual permite fácil diferenciação entre fêmeas. objetivo foi caracterizar o papel torquatus) territorial, analisar diferença defendida cada sexo investigar possíveis diferenças pesquisa realizada Estação Ecológica Águas Emendadas (ESECAE) Brasília/DF. realizado 2022 2023.
