“…Studies have shown that breeding birds may reduce their home range size during the egg and nestling stages (Amaral & Macedo 2003, Moraes et al 2018. Our data refute those results, since in November the area occupied by A2 was larger, when the pair had nestlings and perhaps needed to fly distantly to search for food to feed themselves and their offspring.…”

Detailed studies on the home range size and habitat use of a species are important for the understanding of population dynamics and density. The Southern Streaked Flycatcher (Myiodynastes maculatus solitarius) is a common, widely distributed austral migrant in Brazil that inhabits open areas, forest edges and urban parks. Surprisingly, very little information exists on even basic aspects of its natural history, and details about its habitat use and home range are essentially unknown. We estimated home range size and habitat selection by M. m. solitarius during the 2017-2018 breeding season at Parque Ecológico do Tietê, an urban park in São Paulo, Brazil. We mist-netted and banded three adult individuals, which were followed for a total of 91 h and 50 min to assess their habitat use and home range. Home range size was 5.40 ± 2.45 ha (95% kernel density) and 2.46 ± 1.70 ha (50% kernel density). We obtained 428 sight records of the three individuals, and the strata most frequently used were the canopy and mid-story, in some places with a relatively high percentage of tree cover. These individuals had a clear preference for forested areas (n = 408), as compared to isolated trees in open areas (n = 20). This study contributes to enhance our knowledge of the natural history of the species and offers important new data on various aspects related to the use of space. These results also suggest that urban green areas promote the occurrence of this species in cities, using urban parks to breed and as stopover sites during migration.

“…Comprender dónde descansan las aves por la noche puede tener implicaciones importantes para su conservación. Algunas especies pueden requerir diferentes hábitats para su actividad diurna y el descanso nocturno (Brown & Sherry 2008, Smith et al 2008, Jirinec et al 2016, Moraes et al 2018, por lo que la protección de toda esta diversidad de hábitats utilizados por las especies debe tenerse en cuenta para la gestión de los paisajes.…”

“…Uno de los aspectos menos conocidos de la historia natural de las aves diurnas es su comportamiento y uso del hábitat en horarios nocturnos (Smith et al 2008, Moraes et al 2018, Gussoni et al 2019, Mitchell & Clark 2019. Aunque hay una idea generalizada de que muchas aves duermen perchadas por la noche, hay pocos estudios enfocados en este comportamiento (Skutch & Schmitt 1989).…”

El uso del hábitat nocturno de las aves diurnas es poco conocido. Este estudio presenta observaciones de los sitios de descanso y comportamiento nocturnal de 18 especies de aves en el sotobosque de las tierras bajas de Costa Rica. Realizamos muestreos nocturnos en hábitats riparios y no-riparios en potreros, bosques secundarios y bosques maduros. Observamos un mayor número de aves posadas en hábitats riparios (67) que en hábitats no riparios (3). El sotobosque ripario es utilizado por un grupo diverso de especies de aves como dormidero. Nuestras observaciones resaltan la importancia de corredores riparios, especialmente en hábitats alterados por el ser humano como los potreros.

“…Pale‐breasted Thrushes are socially monogamous and resident Neotropical songbirds (Sick 1997). Adults (~ 23.4 cm in length) are monomorphic in plumage and weigh ~ 69.1 g, and females are slightly heavier than males (Moraes et al 2018). This species inhabits habitats ranging from riparian forests to green urban areas, where it benefits from exotic plants as food sources and buildings as nesting substrates (Gasperin and Pizo 2009, Batisteli et al 2021).…”

Selection of safe nest sites is a first step toward improving the chances of breeding successfully. Reusing old nests can save time and energy for breeding birds, but nest reuse is rare among open‐cup nesting songbirds and the factors contributing to this behavior and its consequences for reproductive output remain little known. We studied an urban population of Pale‐breasted Thrushes (Turdus leucomelas) in southeastern Brazil to determine whether nest reuse (1) was more likely after a successful nesting attempt both within and between breeding seasons, (2) affected the number of fledglings in the next nesting attempt, (3) reduced the chances of nest parasitism by Shiny Cowbirds (Molothrus bonariensis), and (4) was associated with earlier initiation of nests at the beginning of breeding seasons and shorter re‐nesting intervals within breeding seasons. We monitored 266 nests from 2010 to 2019 and obtained data on 130 re‐nesting events by individually marked birds. Nest reuse was more frequent after successful nesting attempts within breeding seasons. New nests were more likely to be parasitized by cowbirds, which had a negative effect on the number of fledglings per clutch. Reusing nests allowed earlier initiation of breeding at the start of breeding seasons, but did not shorten re‐nesting intervals within seasons. Nest reuse by Pale‐breasted Thrushes followed the win‐stay lose‐switch strategy and corroborated the time‐saving hypothesis. Our results suggest that nest reuse may increase the fitness of Pale‐breasted Thrushes by reducing the likelihood of cowbird parasitism.
