Abstract

Breeding chronology and reproductive success of the Merlin (Falco columbarius richarsonii) were studied in southeastern Montana from 1978 - 1981. Breeding activity spanned 5 mo from the earliest observation of adults to the latest dispersal of adults and young from nesting areas. Clutch size, brood size and fledging success at active nests were similar (P > 0.05) among the 4 yrs. Mortality tended to be highest before the hatching stage. Breeding chronology and reproductive success were similar to results of studies in Canada.
