A general framework for modeling pathogen transmission in co-roosting host communities. [PDF]

Ecology
Abstract Cross‐species transmission of pathogens can be facilitated by frequent contact among wildlife. Cross‐species transmission is often driven by phylogenetic similarity between host species, but the role this plays when multiple host species co‐roost is unknown.

Tree-Cavity Denning of Güiña (<i>Leopardus guigna</i>) and Breeding Productivity From Camera Trap Records. [PDF]

Ecol Evol
Tree cavities are critical habitats for numerous vertebrate species. We report the first evidence of güiña breeding in a tree cavity, with insights from camera trap surveys in south‐central Chile's temperate forests. These findings enhance our understanding of the species' natural history, breeding behavior, and habitat preferences.

Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors. [PDF]

Ecol Evol
In Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

Mitogenomic and Metabarcoding Resources for the Study and Conservation of Keystone Neotropical Raptors [PDF]

Ecol Evol
We characterized complete mitochondrial genomes for nine keystone Neotropical raptors, including four threatened and five near‐threatened species, providing essential resources for phylogenetic and conservation studies. We also developed metabarcoding primers, enabling non‐invasive monitoring of Neotropical raptors via environmental DNA.

Rapid Global Deforestation Leaves Forest-Dependent Raptors With Half of Their Suitable Habitat Remaining. [PDF]

Glob Chang Biol
We analyzed high‐resolution global data on forest change between 2001 and 2023 within the ranges of 369 forest‐dependent raptor species. On average, these species have lost 10% of forest within their ranges since 2001. Seventy‐seven species had already lost at least 15% of additional forest cover within their ranges in the latter half of the 20th ...

Tiny Patch, Big Value: A Small Dry Forest Patch Supports Wildlife Conservation in Guanacaste, Costa Rica. [PDF]

Ecol Evol
This study highlights the biodiversity value of the Murren Reserve, a small tropical dry forest patch in Guanacaste, Costa Rica. Using camera traps and opportunistic observations, researchers documented 32 wildlife species, including federally endangered species like the ocelot (Leopardus pardalis) and puma (Puma concolor), as well as 73 plant species.

Genetic diversity of Toxoplasma gondii isolates obtained from free-living wild birds rescued in Southeastern Brazil

International Journal for Parasitology: Parasites and Wildlife, 2018
Recent studies carried out in Brazil have shown that strains from the same Toxoplasma gondii genotype can infect humans, domestic animals (dogs and cats) and animals slaughtered for human consumption (pigs, sheep, goats, and chickens), suggesting a ...

Breeding latitude predicts timing but not rate of spring migration in a widespread migratory bird in South America [PDF]

, 2019
Identifying the processes that determine avian migratory strategies in different environmental contexts is imperative to understanding the constraints to survival and reproduction faced by migratory birds across the planet.

Nutritional osteodystrophy in South American birds of prey [PDF]

Pesquisa Veterinária Brasileira
: Nutritional osteodystrophy is a metabolic bone disease characterized by increased bone resorption and replacement by fibrous connective tissue, resulting from a diet with excess phosphorus or deficient in calcium or vitamin D.

Bacterial meningoencephalitis in a free Chimango Caracara (Milvago chimango temucoensis)

Brazilian Journal of Veterinary Pathology, 2012
A subadult male Chimango Caracara (Milvago chimango temucoensis) was found in an agricultural beef cattle field of Southern Chile. The bird was non-responsive to visual or auditory stimulation, and unable to fly. Clinical examination showed moderate body
