A study of the House Finch
(Carpodacus mexicanus frontalis).
eye disease gave us an opportunity to test this-and we were surprised to see it actually become worse rather than milder," Dhondt stated.
During Trial l, no significant differences in bird abundance were observed among the three small-seed varieties with five species having > 30 observations: Downy Woodpecker (Picoides pubescens, N = 106), Black-capped Chickadee (N = 63), House Finch
(N = 81), American Goldfinch (N = 691), and House Sparrow (N = 45).
For the Northern Cardinal and House Finch
there was no significant difference in the mean body weights of those infected compared to those that were not (t = 0.07, P > 0.05 and t = 1.47, P > 0.05, respectively), however, in the House Sparrow, infected individuals had a higher mean body weight (t = 2.71, P < 0.01)(Table 2).
Therefore, I monitored the portion of postn atal growth of House Finches
that occurred in the nest by routinely measuring seven morphological traits.
