The Relationships of the Wood Thrush (hylocichla Mustelina) : Some Indications from the Electrophoresis of Blood Proteins
The generic relationships of the Wood Thrush (Hylocichla mustelina) have been called into question by the works of Dilger (1956) and Bourns (1967). The four species of North American woodland thrushes presently referred (32nd Supplement to the A.O.U. Checklist 1973) to the genus Catharus i.e., Hermit Thrush ( Catharus @tutu) ; Gray-cheeked Thrush (C. minima); Swainson’ s Thrush (C. ustuluta); a...
متن کاملDivision within the North American boreal forest: Ecological niche divergence between the Bicknell's Thrush (Catharus bicknelli) and Gray‐cheeked Thrush (C. minimus)
Sister species that diverged in allopatry in similar environments are expected to exhibit niche conservatism. Using ecological niche modeling and a multivariate analysis of climate and habitat data, I test the hypothesis that the Bicknell's Thrush (Catharus bicknelli) and Gray-cheeked Thrush (C. mimimus), sister species that breed in the North American boreal forest, show niche conservatism. Th...
متن کاملAdverse effects of acid rain on the distribution of the Wood Thrush Hylocichla mustelina in North America.
Research into population declines of North American bird species has mainly focused on the fragmentation of habitat on the breeding or wintering grounds [Robinson, S. K., Thompson, F. R., Donovan, T. M., Whitehead, D. R. & Faaborg, J. (1995) Science 267, 1987-1990]. In contrast, research into declines of European species has mainly focused on intensification of agriculture [Donald, P. F., Green...
متن کاملA Winter Distribution Model for Bicknell’s Thrush (Catharus bicknelli), a Conservation Tool for a Threatened Migratory Songbird
Conservation planning and implementation require identifying pertinent habitats and locations where protection and management may improve viability of targeted species. The winter range of Bicknell's Thrush (Catharus bicknelli), a threatened Nearctic-Neotropical migratory songbird, is restricted to the Greater Antilles. We analyzed winter records from the mid-1970s to 2009 to quantitatively eva...
