Priority and use segments for Sandhill Cranes (Antigone canadensis). Segments designated as use areas were utilized during annual spring surveys 2014-2016. Priority areas were determined using statistical modeling. The reduced model that best predicted use by Sandhill cranes included total area of trees, pits, crops and unvegetated sandbar habitats in each segments. Mean distance to conservation lands and roads and minimum distance to transmission lines and towers were also included in the model. Only distance to lines and total tree area had a significant (p < 0.05) relationship with priority core segments.

The objective of our study was to compare winter movement patterns of sympatric greater and lesser sandhill cranes (Grus canadensis tabida and G. c. canadensis) wintering in the Sacramento-San Joaquin Delta region of California (Delta). We marked 31 greaters and 45 lessers with VHF radios and recorded their roosting and feeding locations throughout the wintering periods in 2007/08 and 2008/09. Ten of the lessers were also marked with platform terminal transmitters and tracked via the Argos Satellite System. Compared to lessers, locations of greaters were much more predictable. Greaters showed strong fidelity to wintering sites and moved between discrete wintering areas less frequently. During the second year of...
