I plan to study Calliope hummingbird distribution at three banding sites (even after reading the Gotelli and Ellison paper!).
All three banding sites that I have chosen have more Rufous than Calliope captures, but the percentage of Calliope captures is distinct at each site. The Cinnabar site had the fewest numbers of hummingbirds overall, almost all of which are Rufous. The Cassiar Ranch site has the highest percentage of Calliope captures. The Private Residence site has the highest numbers of hummingbirds overall, with the Calliope percentage falling somewhere between the two other sites.
Feeding and banding protocols are identical for all sites. All three sites are within 52km of each other, at similar elevations and with abundant water sources. The most obvious differences in my site observations are forest age and density.
My hypothesis is that as surrounding forest age and density decrease, the percentage of Calliope hummingbird captures will increase. The response variable for this project is the percentage of Calliope captures (categorical). Potential explanatory variables for this project are forest age and density (continuous).
