DISTRIBUTION OF THE BLACK-CAPPED VíREO AT FORT HOOD, TEXAS

摘要

We provide complete, updated data on the status of the endangered black-capped vireo (Víreo atricapilla) and its habitat on Fort Hood Military Reservation, Texas. We searched 74,880 ha of Fort Hood during spring and summer 2002 and 2003, noting the locations of potential habitat patches and víreos. We mapped 6,971 ha of potential habitat, 90% of which was occupied. Such high occupancy suggests that vireos have colonized most of the available vireo habitat on Fort Hood. We detected 1,846 male vireos. The area of occupied habitat and number of male vireos both exceed goals set in the Endangered Species Management Plan for Fort Hood. Assuming that half of the male vireos had mates, Fort Hood alone would exceed the previously published recovery goal of 750 breeding pairs for the Lampasas Cut Plains set in the recovery plan for the black-capped vireo.
