- Abstract
We analyzed data on hatching failure rates of an introduced population of House Finches (Haemorhous mexicanus) in Gainesville, Florida. We calculated overall hatching failure rates for 67 nests and also compared hatching failure rates of nests (n=53) located on lights under aluminum roofs to nests (n=14) at other locations. Average hatching failure for all nests was 0.201 +/- 0.045 SE. There was no significant difference in hatching failure between nests in lights (0.225 +/-0.053) and other locations (0.113 +/-0.074), Overall, this population has relatively high rates of hatching failure. Two hypotheses could explain such high rates of nest failure: a reduction in genetic diversity because of a founder effect and high nest site temperature. Future studies, therefore, should document both genetic diversity of this population and nest site temperatures.
