Observations of leucistic Turkey Vultures (<em>Cathartes aura</em>) in Jamaica

Journal of Caribbean Ornithology, 2018
Abstract: While censusing for the Golden Swallow (Tachycineta euchrysea) in the Cockpit Country and Blue Mountain regions of Jamaica, we observed six unique leucistic Turkey Vultures (Cathartes aura) across 634 standardized point counts. Leucistic individuals accounted for 0.2% of the total 2,826 Turkey Vultures we documented from 16 January to 12 ...

Mitochondrial Genome Analysis of Philippine Eagles (<i>Pithecophaga jefferyi</i> Ogilvie-Grant 1896) From the Greater Mindanao Faunal Region. [PDF]

Ecol Evol
Mitogenome sequencing is a promising alternative for the genetic studies of animals. In this work, we examined the genetic diversity of the critically endangered and endemic Philippine eagles and their evolutionary relationship to other birds of prey.

Navigating the risks and rewards of scavenging in multipredator, human-impacted landscapes. [PDF]

Ecology
Abstract Large carnivores can influence smaller scavengers through both positive and negative interactions (e.g., carrion provisioning and intraguild killing) and ultimately shape scavenging efficiency. However, we know little about this trade‐off in anthropogenic landscapes where humans kill carnivores and provide carrion subsidies.

EXPERIMENTAL LEAD POISONING IN TURKEY VULTURES (CATHARTES AURA) [PDF]

Journal of Wildlife Diseases, 2003
Lead-induced mortality appears to have been a major factor in the decline of the California condor (Gymnogyps californianus). We orally dosed turkey vultures (Cathartes aura) with BB-sized lead shot from January 1988 through July 1988 to determine physiologic response (delta-aminolevulinic acid dehydratase inhibition, erythrocyte protoporphyrin levels,

The mechanisms of color production in black skin versus red skin on the heads of New World vultures

Avian Research, 2023
A determination of how the color of animal integument is produced is a starting point for investigations into the function and evolution of coloration. The mechanisms that give rise to the color of bare skin of New World vultures are largely unexplored ...

Richness and abundance of diurnal raptors from Fernandez Canyon, Lerdo, Durango

Huitzil, 2020
Biological monitoring is essential to understand population dynamics, ecological processes and emerging problems. In this study we determine the richness and abundance of diurnal raptors in the Fernandez Canyon State Park in Durango, Mexico.

A new haemosporidian parasite from the Red-legged Seriema Cariama cristata (Cariamiformes, Cariamidae)

International Journal for Parasitology: Parasites and Wildlife, 2022
Haemoproteids (Haemosporida, Haemoproteidae) are a diverse group of avian blood parasites that are transmitted by hematophagous dipterans. In this study, we describe Haemoproteus pulcher sp. nov.
