Effects of litter floor access and inclusion of experienced hens in aviary housing on floor eggs, litter condition, air quality, and hen welfare

Poultry Science, 2018
With different cage‐free (CF) housing styles and management schemes, retailers have developed their own CF criteria. One highly debated aspect is if hens may be kept inside the system for part of the day—during the first few hours after lights‐on ...

Diet‐manipulated body condition affects onset and speed of moult in common bulbuls in a tropical environment

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
Resource acquisition and allocation are central to life history theory, explaining the diversity of strategies among species as well as the distribution of events over the annual cycle. Moult is a major phase in the annual cycle of birds, but explanations for moult scheduling are heavily biased towards temperate systems with seasonal breeding patterns.

Supplemental feeding as experimental tool to understand why birds do not lay earlier in the season

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
The timing of avian reproduction might be affected by the costs of egg production in early spring. To study these costs, supplemental feeding experiments have been conducted where birds are provided with food prior to egg laying. We discuss the opportunities and pitfalls of such experiments.

SPACIAL ILLUMINANCES VARIABILITY AND ENERGY CONSUMPTION IN AVIARIES FOR LAYING HENS EQUIPED WITH COMPACT FLUORESCENT LAMPS AND LIGHT EMITTING DIODE [PDF]

Engenharia Agrícola, 2016
The spatial illuminance distribution interferes in the commercial production of eggs and electric energy consumption, being considered the second major source of costs in the production chain.

Seasonal activity and behavioural responses to artificial light at night in migratory and non‐migratory sparrows

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
Urban and rural nocturnal environments are increasingly brighter due to artificial light at night (ALAN), causing wide‐ranging biological responses, from reproductive impairment to behavioural changes in diverse taxa. Songbirds may be particularly vulnerable, as their reproductive and migratory behaviours are under endogenous control and regulated by ...

Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)

Ibis, Volume 168, Issue 1, Page 216-229, January 2026.
Monogamy in birds was long considered a general mating system until molecular studies provided evidence of alternative reproductive strategies (ARS), which are now assumed to be present in ~90% of bird species. These ARS or tactics (ART), as we consider them in this study, include extra‐pair copulation, which can lead to extra‐pair paternity or extra ...

Later exposure to perches and nests reduces individual hens' occupancy of vertical space in an aviary and increases force of falls at night

Poultry Science, 2019
Tiered aviaries are intended to improve laying hen welfare by providing resources that enable them to perform essential behaviors. However, hens must be able to navigate these complex systems efficiently and safely.

A narrative review of the impact of anthropogenic light and noise on owls

Ibis, Volume 168, Issue 1, Page 5-24, January 2026.
Today, owls are exposed to increasingly brightly lit nights and noisy environments because of human activities. To understand the impacts of artificial light at night (ALAN) and anthropogenic noise we performed an evidence synthesis. We searched four literature databases and Google Scholar and we collected 39 relevant articles (1945–2024) providing 125

Determination of Ophthalmic Parameters and Ocular Morphology in Ring‐Necked Parakeets (Psittacula krameri)

Veterinary Ophthalmology, Volume 29, Issue 1, January 2026.
ABSTRACT Purpose To determine normal ophthalmic test values and to describe the ocular morphology of ring‐necked parakeets (Psittacula krameri). Materials and Methods 33 captive birds were examined, although not all tests were conducted on each bird.

The notion of the “human zoo”, which has met with great success, appears problematic for a number of reasons, starting with the indistinctness of the processes of animalization it proposes to bring together.
