Habitat and Stratum
We created a scoring system for habitat and stratum that roughly
estimated solar radiation exposure by species. We scored habitats using
the following codes: 0 = tall deciduous forest, 1 = coniferous/montane
forest, 2 = riparian/secondary/gallery forest, or broad forest type use,
3 = stunted/young forest, 4 = forest edge, 5 = scrub/marshes, 6 = open
habitat. We rated stratum by relative stratum within a habitat using the
following codes: 0= ground or near ground. 1= understory/undergrowth, 2
= midstory, 3= subcanopy, 4 =canopy/edge/open. Using data from Dunn and
Garrett (1997), Curson (2010), Stevenson and Whittle (2013), Rodewald(2015) and Schulenberg (2019) we scored the habitat
and foraging stratum during the breeding and wintering periods for each
species. We also scored the stratum of nest placement and the nest type
from these sources. We coded nest types as the following: 0 = cavity, 1
= dome/closed, 2 = open cup.
