摘要: ABSTRACT. Recent research has confirmed the efficacy of migration monitoring to estimate trends in populations raptors sampled at traditional watch-sites. We used autumn satellite tracks 57 adult Ospreys (Pandion haliaetus) captured on breeding range North America between 1995 and 2000 assess extent which their populations. (1) 3-km-wide 6-km-wide linear trajectories (migration paths) that connected locations with straight lines (2) utilization distributions derived from Brownian bridge movement models proportions likely have been detected by watch-sites tagged birds, describe geography southward South America. The path method estimated continental detection rates 12–23%, regional maxima 21–36% eastern This analysis indicated 8–20% all could ≥1 ...
