Auteur(s) et Affiliation(s)



Description :
Brown-headed Nuthatches (Sitta pusilla) were examined at 2 sites in Georgia, United States, during winter to assess spatial variation in mixed-species flock participation and in activity patterns (mainly bark traversing, cone foraging, and seed hammering). Spatial variation was examined at 4 scales : between sites, between habitat-patch types (pine vs. mixed woodland) within a site, between 3 species, and among microhabitats within trees. No evidence was found for variation in microhabitat use between sites, or between flocked and nonflocked nuthatches. Dicussion of the results.
