Morphological Consequences of Migration in Passerines

2003
Migration, like any other ecological factor, shapes the morphology of birds. Most ecomorphological studies of migration have mainly considered external features (e.g. Cox 1968; Gaston 1974; Greenberg 1981). Winkler and Leisler (1992) partly overcame this deficit and related skeletal and myological measurements to migration in several passerine and non ...

Adoption by a Territorial Passerine

The Wilson Journal of Ornithology, 2009
We observed and video-taped active- ly nesting adult Eastern Bluebirds (Sialia sialis) repeatedly feeding abandoned conspecific juveniles in a nearby nest. We used molecular techniques to confirm these nestlings were unrelated to the adults that fed them.

MOUTHSPOTS OF PASSERINE NESTLINGS

Ostrich, 1976
Summary Maclean, G. L. & Vernon, C. J. 1977. Mouthspots of passerine nestlings. Ostrich 48:95-98. Among passerine families a pattern of black spots in a yellow mouth occurs universally only in the Sylviidae and the Alaudidae. The conservative configuration of these spots seems to indicate a true relationship between the warblers and the larks, and the ...

Bacterial and Parasitic Diseases of Passerines

Veterinary Clinics of North America: Exotic Animal Practice, 2009
Many veterinarians are relatively unfamiliar with the passerines. The aviculture, diagnostic procedures, and common diseases, and their treatment have been discussed in several recent publications. Owners of passerines (songbirds) are using veterinary care in increasing numbers as aviculturists recognize the advances in avian medical and surgical ...

Passerine birds (Passeriformes)

2009
Abstract The Order Passeriformes is the largest clade of its rank in birds, encompassing from roughly 40–100 families depending on the classification. In recent years molecular systematic data have greatly clarified interfamilial relationships, although many nodes remain poorly supported and it is clear that numerous traditional families
