Genetic variability of Conopophaga lineata (Conopophagidae) (Wied-Neuwied, 1831) in Atlantic Forest fragments

open access: yesBrazilian Journal of Biology
Forest fragmentation affects bird populations in many ways, modifying the composition of communities and favouring open country species. The Atlantic Forest is considered one of the most important biomes in the world, due to its great biodiversity ...

Sedimentary Metagenomics Reveal Avian Community Transitions From the Last Glacial Maximum to the Holocene

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We used sedimentary ancient DNA shotgun metagenomics to reconstruct past bird communities in northern high‐latitude environments. By using long time series and data collected across a large environmental gradient, we contributed in a unique and explorative way to the understanding of palaeoecological dynamics between birds and their habitat on the ...

First Record of Dark‐sided Flycatcher (Muscicapa sibirica) for Temperate North America: Intercontinental Vagrancy and Migratory Misorientation

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We document the extraordinary occurrence of a Dark‐sided Flycatcher (Muscicapa sibirica)—a migratory passerine from East Asia—in California, USA. We discuss the little‐known phenomenon of intercontinental vagrancy in migratory landbirds and examine this case study in detail, providing analysis of the age, molt status, subspecies, and likely origins of ...

Leucocytozoon infections in tits (Aves, Paridae): blood and tissue stages investigated using an integrative approach

open access: yesParasite
Leucocytozoon species are cosmopolitan and prevalent avian parasites, with some infections being lethal, mainly due to the exo-erythrocytic development of the parasite in bird tissues.

Spatial Differentiation Among Family Members of the Cooperatively Breeding Giant Babax Dynamically Adjusts to Temporal Fluctuations in Offspring Demand for Parental Care

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This research provided evidence that division of labor indeed occurred when offspring were in need of parental care. Therefore, labor division may serve as the underlying mechanism for different parental care strategies and movement patterns among group members in the cooperatively breeding system of giant babaxes.

Ticks on birds in a savanna (Cerrado) reserve on the outskirts of Uberlândia, Minas Gerais, Brazil Carrapatos em aves de uma reserva do Cerrado na periferia de Uberlândia, Minas Gerais, Brasil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2013
We report tick infestations on birds, in the environment and on domestic animals in a non-forested phytophysiognomy, the savanna-like Cerrado sensu stricto, in a natural reserve on the outskirts of the urban area of Uberlândia, Minas Gerais, Brazil.

Introducing TropiCam‐AI: A taxonomically flexible automated classifier of Neotropical arboreal mammals and birds from camera‐trap data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1235-1247, April 2026.
Abstract Rapid, accurate assessment of arboreal vertebrates in tropical forests remains a bottleneck for large‐scale biodiversity monitoring, due to the challenges and effort associated with traditional survey methods. To bridge this gap, arboreal camera‐trapping is emerging as a promising way to observe otherwise elusive species, opening new avenues ...

Mites of the genus Neharpyrhynchus Fain (Acariformes, Harpirhynchidae) from Neotropical birds

open access: yesZooKeys, 2011
Three new species of parasitic mites of the genus Neharpyrhynchus Fain (Acariformes, Harpirhynchidae) are described from Neotropical birds, N. chlorospingus sp. n. from Chlorospingus pileatus (Passeriformes, Emberizidae) from Costa Rica, N.
