A Derived Morphology of the Quadrate May Support a Previously Unrecognized Major Higher-Level Clade of Neoavian Birds. [PDF]

J Morphol
The avian quadrate plays a critical role in cranial kinesis, but few comparative studies exist of its morphological variation across higher‐level taxa. In this study, the occurrence of a markedly concave articular facet of the condylus medialis is surveyed across neornithine birds.

Mechanisms of group‐hunting in vertebrates

Biological Reviews, Volume 98, Issue 5, Page 1687-1711, October 2023., 2023
ABSTRACT Group‐hunting is ubiquitous across animal taxa and has received considerable attention in the context of its functions. By contrast much less is known about the mechanisms by which grouping predators hunt their prey. This is primarily due to a lack of experimental manipulation alongside logistical difficulties quantifying the behaviour of ...

Avian Influenza Screening in Captive Wild Birds and Biosecurity Appraisal of Zoological Gardens in Southwestern Nigeria. [PDF]

Vet Med Int
Avian influenza (AI) is a severe respiratory disease affecting wild and domestic birds globally. There is currently no approved vaccine for AI control in Nigeria. Therefore, biosecurity measures remain the primary preventive strategy. However, there is limited information on the AI carrier status of captive wild birds and the implementation of ...

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

Ibis, Volume 164, Issue 2, Page 505-518, April 2022., 2022
Cosmetic coloration is not a common phenomenon among bird species. Adult Bearded Vultures Gypaetus barbatus typically show orange coloration in head, chest, belly and tarsus feathers that is the result of mud baths in ferruginous substrates. Several non‐mutually exclusive visual signalling hypotheses can be proposed to explain this phenomenon ...
