SPATIAL VARIATION IN FORAGING OF THE BLACK-THROATED GREEN WARBLER ALONG THE SHORELINE OF NORTHERN LAKE HURON

Black-throated Green Warbler (Dendroica virens) Science Article 1

abstract

The Great Lakes strongly influence local climate, vegetation, and animal communities,all of which are important to both migrating and breeding birds. This influencecan be considerable during springtime in nearshore habitats, as onshore winds depress airtemperatures, delaying development of shoreline vegetation relative to inland areas. Thesedevelopmental differences also may affect abundance, distribution, activity, and growth ofinsect prey, resulting in spatially-related differences in foraging by birds.
