TLDR
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
TLDR
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)
TLDR
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)?
TLDR
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 Feather Postures of Birds and the Problem of the Origin of Social Signals
TLDR
It is suggested that this physiological relationship between thwarting and feather erection is the basis of all feather-posture displays, and the detailed study of the physio-ethology of thwarting would greatly assist in advancing the study of social signals in animals.
Hostile, Sexual, and Other Social Behaviour Patterns of the Spice Finch (Lonchura Punctulata) in Captivity
Three main groups of social reactions, commonly observed in captive Spice Finches, are the main subjects of this paper. The first group comprises a number of patterns reflecting the Spice Finch's
FURTHER OBSERVATIONS ON THE BEHAVIOUR OF THE JAY GARRULUS GLANDARIUS
TLDR
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
TLDR
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.
TLDR
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)
TLDR
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.
