Population Status And Geographic Distribution Of Greater Sandhill Cranes In The Mid-Continent Population, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
Number and geographic distribution of greater sandhill cranes (Grus canadensis tabida) in the mid-continent population (MCP) of sandhill cranes were evaluated. G. c. tabida comprised 7 of 133 (5.3%) individuals of 3 subspecies which projects to 31,579 ± 11,661 (SE) individuals in an estimated spring MCP of 600,000 cranes. From a platform transmitting terminal (PTT)-marked sample representative of the geographic distribution of G. c. tabida, 10 of 13 (77%) settled during the breeding season in east-central Canada/Minnesota, including 4 in northwestern Minnesota, 4 in Manitoba (2 at sites near the Minnesota border), and 2 in Ontario. Three …

First Breeding Records And Historical Status Of Sandhill Cranes In New England, Scott M. Melvin
Proceedings of the North American Crane Workshop
Sandhill cranes (Grus canadensis) nested at 4 sites in south-central Maine between 2000 and 2008 and at single sites in western Massachusetts and west-central Vermont in 2007 and 2008, continuing their eastward range expansion. Of 13 nests observed, 5 were in a lacustrine marsh, 2 were in a riverine marsh, and 2 were in beaver-impounded palustrine marshes, all dominated by cattail (Typha spp.); 2 were in lacustrine fen habitat dominated by sedges (Carex spp.), sphagnum, and leatherleaf (Chamaedaphne calyculata); 1 was in a lacustrine fen dominated by slender sedge (Carex lasiocarpa …
