| Abstract: | We constructed a linear, discrete-time, 3-age-class population model for peregrine falcons (Falco peregrinus anatum) in Colorado, USA, from estimates of survival and reproduction derived from banded birds (1973-2001) and monitored nests (1989-2001). Survival estimates were 0.544 ± 0.077 for 0-1-year-old birds, 0.670 ± 0.098 for 1-2 year olds, and 0.800 ± 0.054 for birds >2 years of age. Average young produced per pair was 1.660 (SE = 0.044), but we found considerable variation across years (minimum = 1.388 ± 0.155 in 1995; maximum = 2.122 ± 0.139 in 2000). The population model constructed from these estimates predicted an annual rate of population increase of 1.029 if females were to reproduce at 3 years of age, and 1.080 if they first reproduced at 2 years of age. With appropriate estimates of population parameters, our model provides a method for managers to estimate impacts of falconry harvest upon wild peregrine stocks. |
