Ground-roosting in domestic fowl (Gallus gallus domesticus) in The Gambia: the anticipation of night


Kent, J P; McElligott, A G; Budgey, H V (1997). Ground-roosting in domestic fowl (Gallus gallus domesticus) in The Gambia: the anticipation of night. Behavioural Processes, 39(3):271-278.

Abstract

The ground-roosting behaviour of a semi-feral population of domestic hens with broods of chicks was measured in The Gambia, West Africa. Although neither day length nor time of sunset changed significantly over the duration of the study (January–March 1995), mean daily light intensity showed a significant increase. This resulted in an increasingly rapid decline in light intensity at dusk as the season progressed. Hens went to roost significantly later in the day, and at lower light levels, over the course of the season. The results support a model suggesting that the cue to start roosting is a certain light level, constant over the season, but the ‘settling period' required means that the hens finally roost at later times and at lower light levels as the season progresses.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
