Distribution An D Dispersion Patterns Of San Dhill Crane Flocks In The Platte River Valley, Brian Lorenz, Felipe Chavez-Ramirez
Proceedings of the North American Crane Workshop
We evaluated sandhill crane (Grus canadensis) flock distribution and dispersion patterns along the Platte River Valley, Nebraska, in 2002-2003. The objectives were to: (a) determine the overall distribution and relationship between roosting and foraging flock numbers by bridge segments, (b) evaluate flocking characteristics in relation to abundance of cranes in different bridge segments and total abundance, and (c) correlate dispersion patterns and habitat use to period of migration, roost locations, and habitat types. Preliminary predictions included: foraging flock dispersions would be correlated with roost locations; greater numbers and larger flock sizes will be present in bridge segments with …
