Filial Cannibalism at a House Finch Nest

The Wilson Bulletin, 2005
We report on a female House Finch (Carpodacus mexicanus) eating one of her own eggs from a clutch of six on the 3rd day of incubation. This observation is a confirmed case of filial cannibalism in the egg stage. The reason for this behavior is unknown, but we suggest and discuss three possibilities: (1) an idiosyncratic response to human disturbance ...

Intra- and Interspecific Aggression in House Finches and House Sparrows

The Condor, 1975
Although House Finches (Carpodacus mexicanus) and House Sparrows (Passer domesticus) are distinct taxonomically, they share several ecological and behavioral similarities. Both are gregarious and are semi-colonial nesters, defending only a small, variable territory surrounding the nest (Thompson 1960a, Summers-Smith 1963).

Health Survey of House Finches (Carpodacus mexicanus) from Wisconsin

Avian Diseases, 2004
We conducted a health survey of house finches (Carpodacus mexicanus) without evidence of Mycoplasma gallisepticum infection in order to establish baseline population health measures and estimate prevalence of potential pathogens likely to influence host susceptibility to mycoplasmosis.

Variation in Color of Male House Finches

The Condor, 1931
Descriptions of the California House Finch (Carpodacus mexicanus frontalis) are quite uniform in recognizing that orange occasionally takes the place of the typical red in the color of the males. Baileycx), Hoffmann(2), Dawsonc3) and Wyman(4) all mention this in their descriptions of the species.

Potential for Transmission of the Finch Strain of Mycoplasma gallisepticum between House Finches and Chickens

Avian Diseases, 1998
Although Mycoplasma gallisepticum (MG) is established in house finch (Carpodacus mexicanus) populations in at least 33 states, the potential risk of MG introduction to domestic poultry by infected finches currently is unknown. The objectives of this study were to determine if chickens could be infected with the finch strain of MG via direct, across ...

EPIDEMIC MYCOPLASMAL CONJUNCTIVITIS IN HOUSE FINCHES FROM EASTERN NORTH AMERICA

Journal of Wildlife Diseases, 1998
In the winter of 1993-94, house finches (Carpodacus mexicanus) with severe conjunctivitis (later shown to be caused by Mycoplasma gallisepticum) were first observed in sub-urban Washington D.C. (USA) and adjacent states. Using a large network of volunteer observers in eastern North America, we were able to track the monthly prevalence of the disease ...

The Photorefractory Period of the House Finch

Ecology, 1968
The timing mechanisms of testicular regression and photorefgractoriness were investigated with the Houswe Finch. Testicular regression is completed by August and is followed by a month and a half photorefractory period. Resumption of complete photosensitivity is an indicidual, gradual precess of several months.
