Abstract:: My objectives were to: 1) develop a point count technique for estimating relative abundance of band-tailed pigeons (Columbafasciata monilis), 2) determine the availability, distribution, and interspersion of mineral sites, and nesting and foraging cover in relation to abundance of band-tailed pigeons in west-central Oregon, and 3) test the hypothesis that...

Abstract:: Index counts for the Pacific Coast race of the band-tailed pigeon (Columba fasciata monilis) have declined by -2% per year since survey efforts began in the 1950's and 60's. Mineral sites, important resources with high ion concentrations, are regularly visited by band-tailed pigeons which nest in surrounding forest lands. I...

Creator:: Leonard, Jerome Patrick
Abstract:: Pacific Coast band-tailed pigeons (Columba fasciata) have declined markedly during the past several decades. Despite implementation of increasingly restrictive hunting regulations, populations have shown minimal signs of recovery. I radio-marked 127 adult band-tailed pigeons in the central Oregon Coast Range in April-May of 1993-95 to document nesting chronology and productivity,...

Creator:: Main, Martin Benjamin
Abstract:: I studied sexual segregation in mule deer (Odocoileus hemionus) and white-tailed deer (Q. virginianus) in different environments and at different population densities to test the hypothesis that sexual segregation occurs in ungulates as the result of different reproductive strategies; females select habitat and behave in manners primarily designed to promote...
