In the Mississippi Coastal Plain of the southeastern United States, we explored relationships among bird species
and vegetation types and landscape characteristics at four different scales. We modeled abundance of priority avian
species from Breeding Bird Surveys using land class metrics at 0.24, 1, 3, and 5-km extents. Our modeling method was
logistic regression and model selection was based on Akaike’s Information Criteria and validation with reserved data.
Northern bobwhite (Colinus virginianus), red-headed woodpecker (Melanerpes erythrocephalus), northern parula (Parula
americana), Swainson’s warbler (Limnothlypis swainsonii), prairie warbler (Dendroica discolor), hooded warbler (Wilsonia
citrina), and brown-headed cowbird (Molothrus ater) had models containing positive area or core area variables.
White-eyed vireo (Vireo griseus) and gray catbird (Dumetella carolinensis) had models with a combination of area and
edge associations at different scales. Acadian flycatcher (Empidonax virescens), red-bellied woodpecker (Melanerpes
carolinus), wood thrush (Hylocichla mustelina), and yellow-breasted chat (Icteria virens) had positive edge density models.
Modeling at different scales produced more complete habitat associations for most species and landscape variables
were more influential at larger extents than the smallest extent. Although Mississippi is heavily forested, the landscape is
unexpectedly fragmented, with small areal extents of vegetation types. Managers should seek to provide large extents of a
variety of habitats, including historically representative vegetation types such as low density pine, to support persistence
of a complete suite of avian species.
