Abstract

Frequency, magnitude, and timing of reproduction in Rio Grande Wild Turkey (Meleagris gallopavo intermedia) hens were studied in northeastern Colorado in 1986 and 1987. All adults (n = 12) and 95% (n = 20) of yearlings were known to attempt nesting. Adults initiated first nest attempts earlier than yearlings in 1987 but not 1986. Adults and yearlings did not differ in clutch size or nesting success. There was an inverse relationship between clutch size and initiation date of first nests by adults. Clutch and egg size, however, were not related. Among yearlings, body mass at capture in February was positively correlated with subsequent nest-initiation date. Environmental and social stimuli, but not winter severity, are hypothesized proximate conditions regulating reproduction in this Wild Turkey population.
