| Summary: | ABSTRACT—I use point-count survey data collected from 171 locations across 11 vegetation conditions in western Mexico to illustrate common patterns of winter habitat use by 97 Nearctic-Neotropical migratory landbird species. A number of bird species are relatively restricted in their habitat use, with some [e.g., Northern Waterthrush ( Parkesia noveboracensis ), American Redstart ( Setophaga ruticilla )] occurring only in relatively undisturbed habitats, and others [e.g., Say's Phoebe ( Sayornis saya ), Horned Lark ( Eremophila alpestris )] occurring only in relatively disturbed lands associated with agriculture. A large number of bird species [e.g., Cassin's Vireo ( Vireo cassinii ), MacGillivray's Warbler ( Geothlypis tolmiei )] use every one of the vegetation types considered, from low-elevation tropical deciduous forests to high-elevation conifer forests. Bird species showing patterns of restricted habitat use deserve conservation attention, but so might more broadly distributed species that become significantly less abundant in human-altered habitats. Identifying the latter will require the inclusion of a wider spectrum of altered vegetation types/conditions than what I included here, or than what is typically considered in wildlife-habitat relationship programs. nothing else Funding provided by: various, across 20 years many years ago Crossref Funder Registry ID: Award Number:
