2007 Yellow-Billed Cuckoo Study Results. Appendix: Yellow-Billed Cuckoo Survey and Detection Forms. San Antonio to San Marcial, New Mexico

摘要

Any Yellow Billed Cuckoo detected during these surveys were considered a resident, however, due to the fact that territory sizes were large and overlapped, GIS SOftware was used to minimize double-counting and to delineate probably territory locations. For the purpose of the report, a territory is considered any dumping of detections within a 500m radius representing a pair, suspected pair, or single unpaired YBC. Habitat characteristics were also taken into consideration when delineating territory locations.
