Black-Throated Gray Warblers on Vancouver Island

Territorial Movements of Black-throated Blue Warblers in a Landscape Fragmented by Forestry

—Many forest bird species show inhibition to entering open areas, including crossing habitat gaps. We examined the responses of Blackthroated Blue Warblers (Dendroica caerulescens) to conspecific song playback within forest, at clearcutforest ecotones, and across logging roads to assess movements of this Neotropical migrant into open areas. Males responded readily to song playbacks in all areas...

Population density affects foraging behavior of male Black-throated Blue Warblers during the breeding season

Foraging behavior often reflects food availability, a resource that may increasingly limit breeding birds as intraspecific crowding increases. Measuring foraging behavior, therefore, provides a way to investigate effects of population density on food limitation, an important link in understanding how crowding functions to regulate populations. We quantified three components of foraging behavior...

This report is part of an ongoing project, begun in IYX7, drain the district. Most of the coalfield is covered by till which limits exposures to the showline, rivers and roadcuts. Climate is fairly mild and wet, and snowfall is common to update knwledge of the coal basins of Vancouver Island. Limited information exists pertaining to coelmeasures of the Squash crudfield or snh-basin (the terms c...
