Adult and hatch-year blackpoll warblers exhibit radically different regional-scale movements during post-fledging dispersal.
Using a broad-scale automated telemetry array, we explored post-fledging movements of blackpoll warblers breeding in Atlantic Canada. We sought to determine the full spatial scale of post-fledging dispersal, to assess support for three hypotheses for regional-scale post-fledging movement, and to determine whether learning influenced movement during this period. We demonstrated that both young a...
متن کاملMigratory blackpoll warblers (Setophaga striata) make regional-scale movements that are not oriented toward their migratory goal during fall
BACKGROUND Regional scale movement patterns of songbirds are poorly known largely due to difficulties tracking small organisms at broad scales. Using an array of over 100 automated radio telemetry towers, we followed Blackpoll Warblers (Setophaga striata) during fall migration in the Gulf of Maine region, and assessed how their regional scale movement pathways varied with age, distance to natal...
متن کاملPost-fledging Survival and Dispersal of Peregrine Falcons during a Restoration Project
--We monitored 38juvenile Peregrine Falcons (Falcoperegrinus) up to 3 mo immediately after their release from a hack box during 1999-2000. The restoration site was a cliff near Eagle Point Park in Dubuque, Iowa. Falcons were released in a staggered manner from mid-June until late July each summer. Older falcons remained at the site longer than at previous urban releases and interacted with the ...
متن کاملPost-Fledging Dispersal of Burrowing Owls in Southwestern Idaho: Characterization of Movements and Use of Satellite Burrows
Using radiotelemetry, we monitored dispersing juvenile Western Burrowing Owls (Athene cunicularia hypugaea) within a migratory population in southwestern Idaho during 1994 and 1995. Owls remained within natal areas for an average (? SE) of 58 ?+ 3.4 days post-hatching before moving permanently beyond 300 m, which was our operational cutoff for dispersal from the natal area. On average, owls dis...
متن کاملPost-fledging survival of northern goshawks: the importance of prey abundance, weather, and dispersal.
Effective wildlife conservation strategies require an understanding of how fluctuating environmental conditions affect sensitive life stages. As part of a long-term study, we examined post-fledging and post-independence survival of 89 radio-marked juvenile Northern Goshawks (Accipiter gentilis) produced from 48 nests in northern Arizona, USA, during 1998-2001. Information-theoretic methods were...
