Abstract

Walk-in traps were used to capture 132 female and 99 male Greater Prairie-Chickens (Tympanuchus cupido) in northeastern Colorado during 1986-1989. Females were captured on 6.7% and males on 5.0% of 1970 funnel days (usually one funnel per trap). Trap placement on leks influenced capture success of males and females; both sexes were more difficult to capture as they walked away from the center of leks than toward the center of leks. The likelihood of capturing females appeared to peak during 5-20 April; these dates corresponded to the peak period of female attendance on leks. In contrast, males were captured throughout the breeding season (March-April). This technique provides excellent opportunities to capture prairie grouse, particularly females, with minimal disturbance on leks. /// En un estudio que se llevó a cabo en el noreste de Colorado durante 1986-1989 se utilizaron trampas de túneles, para la captura de 132 hembras y 99 machos de pollos de la pradera (Tympanuchus cupido). En 1970 días-túneles (cada conjunto de túneles contado como un día-tunel) se capturaron 6.7% y 5.0% de hembras y machos, respectivamente. La localidad de la trampa en los leks influyó en el éxito de captura de hembras y machos; ambos sexos resultaron ser más dificiles de capturar mientras se movían desde el centro del lek hacia la periferia que durante el movimiento en dirección contraria. La probabilidad de capturar hembras pareció maximizarse del 5-20 de abril; estas fechas corresponden al pico del periodo de visita al lek por parte de las hembras. En contraste, los machos fueron capturados a través de toda la época de reproducción (marzo-abril). Esta técnica facilita la captura de hembras, con disturbios mínimos al lek.
