Behavioural and hormonal effects of member replacement in captive groups of blue-fronted amazon parrots (Amazona aestiva)

Social species in captivity may face allostatic overload due to artificial grouping and other social constraints. In rescue centres, groups of psittacines are constantly mixed due to the arrival and/or release of individuals; this procedure is potentially harmful to animal...

Budgie in the mirror: An exploratory analysis of social behaviors and mirror use in the Budgerigar (Melopsittacus undulatus)

Despite their prevalent use amongst avian species, particularly in Budgerigars, the relationship between mirror use and social behaviors is in need of elucidation. After establishing social behavior measures (e.g., agonistic and pair-bond data) in a colony of Budgerigars, mirrors were...

Enhancing welfare of Zebra finches through the use of environmental enrichment

This article will describe alterations made by the University of Glasgow to increase the welfare of our Zebra finches by providing them with a more complex environment to engage with. It will describe how we have maximised the enrichment potential...

Husbandry of wild-caught song sparrows (Melospiza melodia)

Conservation and research efforts occasionally rely upon bringing wild animals into human care to establish breeding programs and to understand their biology. Wild‐caught birds may have husbandry requirements that differ from captive‐reared animals due, in part, to their social development...

Evaluation of best practices for the euthanasia of zebra finches (Taeniopygia guttata)

Although zebra finches (Taeniopygia guttata) have been used in biomedical research for many years, no published reports are available about euthanizing these small birds. In this study, we compared 5 methods for zebra finch euthanasia: sodium pentobarbital (NaP) given intracoelomically...

Evaluation of alternative euthanasia methods of neonatal chickens

Hatched male layer chicks are currently euthanized by maceration in the United States. Public concerns on the use of maceration have led to the search for alternative methods. We hypothesized that gas inhalation and low atmospheric pressure stunning (LAPS) are...

Assessment of plumage and integument condition in dual-purpose breeds and conventional layers

The assessment of plumage and integument condition in laying hens provides useful information about the occurrence of feather pecking and cannibalism. Although feather loss and skin injuries can result from mechanical abrasion or clinical diseases, they are valid animal-based indicators...

Free dietary choice and free-range rearing improve the product quality, gait score, and microbial richness of chickens

Poultry welfare has been extensively studied; however, there is a lack of rigorous scientific knowledge relating to the different aspects of welfare factors and how this may contribute to the production quantity and product quality as well as the welfare...

Evaluation of two compressed air foam systems for culling caged layer hens

Outbreaks of avian influenza (AI) and other highly contagious poultry diseases continue to be a concern for those involved in the poultry industry. In the situation of an outbreak, emergency depopulation of the birds involved is necessary. In this project,...

Hens vary their vocal repertoire and structure when anticipating different types of reward

The vocalizations of nonhuman animals are considered potential indicators of motivational or internal state. In many species, different call types, and structural variation within call types, encode information about physical characteristics such as age or sex, or about variable traits...
