2. a similar and related North American bird, Carpodacus mexicanus



(Cannabina cannabina), a bird of the family Fringillidae of the order Passeriformes. The body measures about 13 cm long. The males have a crimson breast and forehead, a brown back, and a white abdomen. The females and young are grayish brown. The linnet is found in Europe, North Africa, and western Asia. In the USSR it is distributed from the western borders to the Ob’ River basin. The bird nests in bushes, laying four to six eggs per clutch. It feeds primarily on seeds; the young are also fed seeds. The linnet is useful in weed control. It is often kept as a pet.

The results of our experiments with the house finch demonstrate a "releaser signal" function for dimorphic plumage coloration similar to Marler's (1955b) findings with the chaffinch.
Thus, a simple plumage coloration cue appears to act as a releaser for agonistic behaviors in the house finch.
Our study suggests that orange and red manipulations mimicked male coloration in the house finch, and that blue and green are perceived and reacted to differently.
More is known about the function, evolution, and proximate control of ornamental plumage coloration in the house finch than in any other passerine species" (Hill, 1996, p.
In addition, the best measure of male phenotypic quality in the house finch is nest attentiveness (Hill 1991), but I was unable to measure female nest attentiveness in this study.
One further consideration is that female coloration in the house finch could function in social signaling.
My failure to find such a correlation supports the hypothesis that female coloration in the house finch is a correlated character.
House finch pigmentation: carotenoid metabolism and the effect of diet.
Four birds sustained detectable viremias of 7 days (a Ring-billed Gull, a House Finch, and two Fish Crows).
Viremias generated from oral infection were similar to those from mosquito bite-derived infection, although the onset of detectable viremia was consistently delayed by at least a day (Figure 2), except for the one House Finch and the Great Horned Owl.
We know nonnative birds can do damage to native populations, as the case of the European starling and house finch have shown us.
