Habitat selection Juvenile songbird

Swainson’s thrush rin tion be – a critical period in terms of population viability. Using radio telemetry, we examined factors affecting habitat selection by juvenile Swainson’s thrushes during the post-breeding period in headwater basins in nce th 1997), headwater streams, especially those without fish, have received less research effort and priority for protection from anthropogenic disturbances such as timber harvest (Oregon Department of For-estry, 2010). Although much of the interest in headwater riparian areas has been related to their influence on aquatic biota and downstream kami, 2001; Iwata hite et al., 2005) le is known ssociated along intermittent streams in headwater areas. Singing surveys of breeding birds have provided eviden adults of some species are associated with headwater riparia itats (McGarigal and McComb, 1992), but non-singing juvenile songbirds are often missed using this method. As a result, far less is known about habitat selection by juvenile birds (Faaborg et al., 2010). The few studies published on habitat selection of juvenile songbirds suggest that juveniles in the postfledging period may se-lect different habitat than that used by adults during the breedin
