Vultures as an overlooked model in cognitive ecology

Thijs van Overveld et al.

Summary: Despite unique ecological pressures, vultures exhibit a variety of innovative foraging behaviors and social adaptation skills. Further research is needed to investigate the cognitive basis of vulture skills and their implications in ecology and evolution.

Adult coloration of the Bearded Vulture (Gypaetus barbatus) in the Pyrenees: relation to sex, mating system and productivity

Stephane Duchateau et al.

Summary: The study systematically monitored Bearded Vultures in the Pyrenees between 2016 and 2020, analyzing the relationship between feather coloration, sex, mating system, and average productivity. Results showed that medium color morph was the most common, females were generally darker than males with some overlap, and dominant males in trios were darker than subordinate males. The best predictors of average productivity were years of territory occupation, mating system, and their combination, with coloration not being a significant factor.

Generation of raptor diversity in Europe: linking speciation with climate changes and the ability to migrate

Juan J. Negro et al.

Summary: This study investigates the diversification of raptor species in Europe, the coexistence of closely related species, and the impact of size on migration. By analyzing molecular phylogeny and trophic niche clusters, the study concludes that the rich assemblage of diurnal birds of prey in Europe has emerged recently due to the multiplication of look-alike species with similar trophic ecologies.
