A new fossil vulture (Cathartidae: Cathartes) from Quaternary asphalt and cave deposits in Cuba [PDF]

Bulletin of the British Ornithologists’ Club, 2020
A new small fossil species of vulture from Quaternary asphalt and cave deposits in western Cuba is described herein. Some specimens of this taxon are the smallest known in the genus Cathartes, including the modern Lesser Yellow-headed Vulture C. burrovianus. The extinction of the Cuban megafauna, coupled with the loss of open habitats once dominated by

Vulture Exclusion Halves Large Carcass Decomposition Rates and Doubles Fly Abundance. [PDF]

Ecol Evol
We experimentally excluded vultures from pig carcasses (Sus scrofa) in Costa Rica, under different habitats and across seasons with the aim to assess the impact of vulture population decline on carrion decomposition and insect abundance. Vulture exclusion halved carcass decomposition rates and doubled fly abundance, while dung beetle abundance remained

Multi-locus phylogenetic inference among New World Vultures (Aves: Cathartidae) [PDF]

Molecular Phylogenetics and Evolution, 2016
New World Vultures are large-bodied carrion feeding birds in the family Cathartidae, currently consisting of seven species from five genera with geographic distributions in North and South America. No study to date has included all cathartid species in a single phylogenetic analysis.

Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

The shapes of bird beaks are highly controlled by nondietary factors [PDF]

, 2016
Bird beaks are textbook examples of ecological adaptation to diet, but their shapes are also controlled by genetic and developmental histories. To test the effects of these factors on the avian craniofacial skeleton, we conducted morphometric analyses on

Comparison of eye morphology and retinal topography in two species of new world vultures (Aves: Cathartidae) [PDF]

The Anatomical Record, 2013
ABSTRACTVultures are highly reliant on their sensory systems for the rapid detection and localization of carrion before other scavengers can exploit the resource. In this study, we compared eye morphology and retinal topography in two species of New World vultures (Cathartidae), turkey vultures (Cathartes aura), with a highly developed olfactory sense,

Inclement weather forces stopovers and prevents migratory progress for obligate soaring migrants

Movement Ecology, 2021
Background Migrating birds experience weather conditions that change with time, which affect their decision to stop or resume migration. Soaring migrants are especially sensitive to changing weather conditions because they rely on the availability of ...

The first whole genome and transcriptome of the cinereous vulture reveals adaptation in the gastric and immune defense systems and possible convergent evolution between the Old and New World vultures [PDF]

, 2015
Background: The cinereous vulture, Aegypius monachus, is the largest bird of prey and plays a key role in the ecosystem by removing carcasses, thus preventing the spread of diseases. Its feeding habits force it to cope with constant exposure to pathogens,
