Multimodal signaling in fowl, Gallus gallus.
Many social birds produce food-associated calls. In galliforms, these vocalizations are typically accompanied by a distinctive visual display, creating a multimodal signal known as tidbitting. This system is ideal for experimental analysis of the way in which signal components interact to determine overall efficacy. We used high-definition video playback to explore perception of male tidbitting...
متن کاملGround-roosting in domestic fowl (Gallus gallus domesticus) in The Gambia: the anticipation of night.
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...

متن کاملPlumage Color Allelism in the Red Jungle Fowl (Gallus Gallus) and Related Domestic Forms.
HE lack of an ancestral “standard of reference”, “normal” or “wild type” T for use in genetic studies of the domestic fowl has been of little concern to many poultry geneticists (for a recent discussion of this topic see JAAP and HOLLANDER 1954). In the field of plumage color inheritance, however, a standard of reference seems necessary in describing the action of mutant genes. What the standar...
متن کاملOsteopontin expression in spontaneously developed neointima in fowl (Gallus gallus).
Fowl show spontaneous elevation of blood pressure and neointimal plaque formation in the abdominal aorta at young ages. A similar neointima can be induced by a balloon-catheter-induced endothelium injury to the fowl aorta. Both spontaneously developed and injury-induced vascular lesions exhibit subendothelial hyperplasia consisting of neointimal cells with a synthetic phenotype and abundant ext...
