SUMMER DIET OF THE PEREGRINE FALCON IN FAUNISTICALLY RICH AND POOR ZONES OF ARIZONA ANALYZED WITH CAPTURE-RECAPTURE MODELING
Abstract. We collected prey remains from 25 Peregrine Falcon (Falco peregrinus) territories across Arizona from 1977 to 1988 yielding 58 eyrie-years of data. Along with 793 individual birds (107 species and six additional genera), we found seven mammals and nine insects. In addition, two nestling pe...

Along with 793 individual birds (107 species and six additional genera), we found seven mammals and nine insects. In addition, two nestling peregrines were consumed.

In northern, central, and southeastern Arizona, 74, 66, and 56 avian prey taxa, respectively, were recorded. We used capture-recapture modeling to estimate totals of 111 Ϯ 9.5, 113 Ϯ 10.5, and 86 Ϯ 7.9 (SE) avian taxa taken in these same three areas.
