Re-launched in 2003, the new series serves to rebuild the connection thousands of viewers made For more than 50 years, Hinterland Who’s Who has proudlyīeen bringing Canada’s iconic wildlife directly into Canadians’ homes. It all started in 1963, with black-and-white vignettes about the loon, the moose, the gannet and the beaver.

Welcome to the Web site for Hinterland Who's Who Knowledge on the possibilities of where and what birds might be present are included. Whether it be by regions, habitat, appearance or maybe colour. Each of these links offer the user different methods to identify birds, Same sites are a great asset to seeking out knowledge on birds in other regions of the world. These are links to websites pertaining to the different birding institutions, societies and organizations here in North America. Conservation planning for the persistence of birds requiring early-successional habitat types should consider the ephemeral nature of these areas and the potential contribution from young, regenerating forest.Return to Birds of North America Home Page However, substantial variation existed among species with respect to patterns in habitat use and nest success.

For some species, patterns in reproductive success (reported as interval nest success) mirrored observed patterns in breeding densities. Most shrubland bird species used both glades and regenerating forests more than forest-pasture edge sites, and breeding densities of some species were higher in regenerating forests than in glades. The effect size of habitat type on breeding densities varied among species and indicated important species-specific differences in habitat use. We found support for the effects of habitat type on breeding densities of prairie warbler (Dendroica discolor) and yellow breasted chat (Icteria virens) the effects of habitat type and year on densities of blue-winged warbler (Vermivora pinus), eastern towhee (Pipilo erythrophthalmus), and field sparrow (Spizella pusilla) the effect of year on densities of indigo bunting (Passerina cyanea) and northern cardinal (Cardinalis cardinalis) and no effects on densities of white-eyed vireo (Vireo griseus). In evaluating breeding densities in these habitat types, we compared support for a global model with year, habitat type, and a habitat type x year interaction to several reduced models and a null model with only an intercept, and we used model-averaged coefficients to evaluate effect size. We monitored 8 bird species using spot mapping and total mapping techniques, searched for and monitored nests, and measured vegetation structure within nested circular plots. We studied shrubland bird communities in 3- to 5-year-old regenerating forest (n=3), glade (n=3), and forest-pasture edge (n=3) habitat types in the predominantly forested Missouri Ozarks in 1997-1999. We used an information-theoretic approach to evaluate hypotheses concerning factors affecting breeding bird densities in different early-successional habitat types. Population numbers of many bird species associated with early-successional or disturbance-dependent habitat types are declining.
