Observations of fall migrations of peregrine falcons (Falco peregrinus) on the Texas coast (USA) between 1956-1973 (a total of 1477 birds were seen) reveal chronological differences in the ocurrence of peak numbers of adults vs. immatures and males vs. females. Hunting strategies and prey are discussed. The beach environment is a place where water-birds and land-birds are especially vulnerable to peregrine attacks and is regarded as similar to conditions in the nesting habitat of F.p. tundrius.
