The effect of local and landscape-level characteristics on the abundance of forest birds in early-successional habitats during the post-fledging season in western Massachusetts.

Body condition Body condition indices of American Redstart adults were negatively related to graminoid cover (β = −0.59±0.19, P = 0.008), American Redstart juveniles were positively related to PC1 (“fragmentation”; β = 0.11±0.06, P = 0.049), Ovenbird juveniles were positively related to invasives (β = 0.49±0.25, P = 0.057), and Red-eyed Vireo juveniles were positively related to tree cover (β = 0.71±0.39, P = 0.09), though this relationship was marginally significant.
