Emergence of Livestock-Associated Methicillin-Resistant Staphylococcus aureus ST398 in Wild Birds, Brazil. [PDF]

Microbiologyopen
In a protected forest fragment in southern Brazil, 197 wild birds were sampled, with 12.2% carrying Staphylococcus aureus. Two MRSA ST398 strains, the first reported in Brazilian wild birds, were identified. Genomic analysis revealed resistance and virulence genes, linking these strains to pigs and underscoring the critical need for resistance ...

Nest Microbial Community Dynamics Within the Nest-Building Stage of Green-Backed Tits (<i>Parus monticolus</i>). [PDF]

Ecol Evol
The microbiota in bird nests significantly influences avian reproduction. Using high‐throughput sequencing and microbial network analysis, we examined the microbial diversity, composition, and co‐occurrence networks in green‐backed tit (Parus monticolus) nests during pre‐ and post‐nesting stages. Post‐nesting nests showed increased beneficial microbes,

Effectiveness of Key Biodiversity Areas in representing global avian diversity. [PDF]

Conserv Biol
Abstract Key Biodiversity Areas (KBAs) are the largest and most complete network of significant sites for the global persistence of biodiversity. Although important sites for birds worldwide have been relatively well assessed, a key question is how effectively the global KBA network represents avian diversity.

Climatic niche shifts and ecological sky-island dynamics in Mesoamerican montane birds. [PDF]

Ecol Evol
We describe climatic niche of four Neotropical montane birds through the analysis of climatic factors driving their evolution at inter‐ and intraspecific levels. We tested for differences among lineages within four taxa (Aulacorhynchus, Chlorospingus, Cardellina, and Eupherusa), all associated to Mesoamerican humid montane forests.

Avian diversity and function across the world's most populous cities

Ecology Letters, Volume 26, Issue 8, Page 1301-1313, August 2023., 2023
Understanding the composition of urban wildlife communities is crucial to promote biodiversity, ecosystem function and links between nature and people. We found a significant phylogenetic signal for urban tolerance, site‐level avian richness was positively influenced by the extent of open forest, cultivation and wetlands, and avian functional diversity

Onto the sense of smell in macaws, amazons and toucans: can they use volatile cues of fruits to make foraging decisions?

Integrative Zoology, Volume 18, Issue 4, Page 762-771, July 2023., 2023
We found that scarlet macaws, keel‐billed toucans, and yellow‐throated toucans can rely on olfactory cues to locate food sources. Abstract Over the past decades, empirical evidence has been accumulated indicating that olfactory information plays a fundamental role in bird life history.

Status and distribution in Peru of the Black-Billed Mountain-Toucan Andigena nigrirostris (Waterhouse, 1839)

Revista Peruana de Biología, 2017
In Peru Andigena nigrirostris is considered hypothetical due to the absence of published records. To date ten specimens have been collected and two sound records and a photograph of a free-flying individual have been obtained.
