A critical eye is cast on areas that Animal Welfare regulations have not reached at all, have not gone far enough, or are not regulated or supervised on the plight of birds living in captivity or being studied in the field, which either by neglect, ignorance, or design are subject to practices and procedures that may not meet basic welfare standards.
Bird Welfare in Zoos and Aquariums: General Insights across Industries
This qualitative review highlights findings across industries to inform animal care staff and scientists on the welfare needs of birds within zoos and aquariums and highlights areas where additional research is necessary.


Communication value of displays and postures in Red-vented Bulbul Pycnonotus cafer (Aves: Pycnonotidae)
It is believed that the multi-component signals provide more reliable information for receivers and increase the efficacy of communication in Red-vented Bulbul Pycnonotus cafer.
Facial display and blushing: Means of visual communication in blue-and-yellow macaws (Ara Ararauna)?
A significantly higher proportion of naïve observers judged blushing as being present on photographs taken during the mutual interaction phase than during the control phase, which broadens the scope for further studies to determine whether parrots’ faces provide visual social signals.
The paper deals with the behaviour of captive and wild Garrulus glandarius, a Jay reared by one or two people often show much fear of strangers when adult, and the defensive-threat display seems primarily concerned with defence of nest or young.
Function of crest displays in royal flycatchers (Onychorhynchus)
Royal flycatchers (Onychorhynchus coronatus and 0. mexicanus) of the neotropics have large, brilliantly colored, fan-shaped crests that are usually concealed but can be erected perpendicularly to the
Multi‐functional crest display in hoopoes Upupa epops
Male hoopoes display the crest in a heterospecific context in response to detection of potential threats, which could be a deceptive or pursuit-deterrent signal.
The role of mechanical forces on the patterning of the avian feather-bearing skin: A biomechanical analysis of the integumentary musculature in birds.
The avian integument with its complex structural organization may represent an excellent model for analyzing the nature of interactions between the environment and genetic material and the relevance of integrated analyses of complex organs as mechanically coherent systems for evolutionary and developmental biology is demonstrated.
Vocal repertoire of the New Zealand kea parrot (Nestor notabilis)
Being the most common call type, as well as the default response to another call, it appears that the 'contagious' screech contact call plays a central role in kea vocal communication and social cohesion.
Distribution and Behavioural Ecology of the Sulphur-Crested Cockatoo (Cacatua Galerita L.) in New Zealand
The distribution of C. galerita in Australia and New Zealand was modelled against environmental factors using multiple logistic regression to determine which characteristics of its environment are important in defining their distribution.
Bird Minds: Cognition and Behaviour of Australian Native Birds
Bird Minds contends that the unique and often difficult conditions of Australia's environment have been crucial for the evolution of unusual complexities in avian cognition and behaviour.
