Nests were collected in dense shrub habitats only in 2004 and 2005, as birds typically nested
in these locations at much lower densities.
Supporting evidence comes from studies in ponderosa pine forests, where secondary cavity nesting species that nested
almost exclusively in cavities excavated by primary cavity nesters (i.
Cliff Swallows nested
successfully (produced at least 1 nestling) in 52 of 171 available nest cavities (30.
in grasslands planted as part of the mine reclamation and were surrounded by agricultural fields that included hay in which the Dickcissels also nested
In the only case that pigeons nested
in a lower chamber with an entrance tunnel, the tunnel was short and wide.
Four additional species nested
in C plots but were excluded from analysis because they are not typically considered early successional species and because of low sample sizes: Red-eyed Vireo (Vireo olivaceus), Black-billed Cuckoo (Coccyzus erythropthalmus), Hooded Warbler (Wilsonia citrina), and Yellow-billed Cuckoo (Coccyzus americanus).
an average of 237 [+ or -] 56 m (n = 3) from the preceding year's nest.
Red-tailed Hawks nested
in live oak mottes or mesquite-dominated tree lines, which provided the tallest trees available in the generally open landscape of mesquite savanna and Tamaulipan thornscrub of our study area.
As early as 1902 or 1903, one pair nested
in a deserted pig-sty in western Pennsylvania (Jackson 1903).
