Effects of habitat and time of day on flock size of Turkey Vultures in Cuba (Cathartes aura) [PDF]

ZooKeys, 2018
In agricultural landscapes, the Turkey Vulture Cathartes aura feeds mainly on carcases of domestic animals. In spring 2017, data on 214 flocks of Turkey vultures were collected in a road survey in Cuba (in total 2384 km). Turkey Vultures were found to be

Scavenger Assemblage Behavior at Puma Kills in the Santa Cruz Mountains, California [PDF]

Ecology and Evolution
Scavengers structure food webs through consuming carrion and cycling nutrients in ecosystems. Scavenger assemblages are shaped by multiple factors, including intra‐ and interspecific competition, environmental conditions, and interactions with apex ...

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution. [PDF]

J Anat
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Bridging Evolutionary History and Conservation of New World Vultures [PDF]

Animals, 2023
The New World Vultures (Cathartidae) include seven species of obligate scavengers that, despite their ecological relevance, present critical information gaps around their evolutionary history and conservation.

Fine-scale assessment of home ranges and activity patterns for resident black vultures (Coragyps atratus) and turkey vultures (Cathartes aura). [PDF]

PLoS ONE, 2017
Knowledge of black vulture (Coragyps atratus) and turkey vulture (Cathartes aura) spatial ecology is surprisingly limited despite their vital ecological roles.

Generation Length: Often Ignored and Sometimes Misunderstood. [PDF]

Evol Appl
ABSTRACT Traditional mathematical models of population genetics have generally assumed discrete generations, but most species have overlapping generations. It is necessary to estimate generation length with overlapping generations for purposes of comparison with discrete‐generation models.

Camera Trap Design Determines Taxa Detected at Carrion Sites. [PDF]

Ecol Evol
In this study, we demonstrated that camera trap orientation (i.e., horizontal and vertical) at carrion sites differed in their animal community composition and taxa associations. The vertical camera trap orientation was more likely to detect necrophagous invertebrates, while the horizontal orientation was more likely to detect white‐tailed deer.

Beach Buffet: First Observations of White-Backed Vultures <i>Gyps africanus</i> Feeding on a Cape Fur Seal <i>Arctocephalus pusillus</i> on the Skeleton Coast. [PDF]

Ecol Evol
Vultures are specialized scavengers that provide critical ecosystem services by clearing carcasses, though their activity in African coastal environments has previously been limited to only two documented species (i.e., the Lappet‐faced and the Hooded Vultures).

Evaluation of a Multimodal Anesthetic Protocol for Immobilization in Black Vultures (Coragyps atratus) and Turkey Vultures (Cathartes aura) [PDF]

Veterinary Sciences
Anesthetic protocols for non-invasive immobilization of Black Vultures (Coragyps atratus) and Turkey Vultures (Cathartes aura) for procedures lasting up to two hours are lacking.

Taphonomic signatures of early scavenging by black and turkey vultures. [PDF]

PLoS ONE
Scavenging is critical for nutrient cycling and maintenance of healthy ecosystems. While there is substantial research into the identification of taphonomic signatures from facultative mammalian scavengers, early stage scavenging signatures by vultures ...
