  1. Translocate gamebirds

    A before-and-after study in Iowa, USA (Terry & Varland 1981), found that a population of 16 eastern wild turkeys Meleagris gallopavo silvestris (five males, 11 females) translocated in February 1975 and 1976 from southern Iowa and Missouri, into an area with no resident turkey population, found that the introduced population grew 470% within three breeding seasons, despite slow population growth in the first year (13%). Turkeys had dispersed across an area of 83 km² by the 3rd year after release. Birds were captured with rocket or cannon nets, transported in individual wooden crates, held overnight in an unheated building, before being equipped with a radio transmitter and released. Dispersal and nesting success were calculated from observation and radiotelemetry data.
