Upper canopy within vireo habitat is relatively open. The golden-cheeked warbler is a migratory songbird present in Texas during the breeding season of early March through early August. The songbirds prefer an oak-juniper wood that possesses a high percentage of tree canopy.

Ashe juniper within the oak-juniper woods normally occupied by the warbler is not predominately second growth or multi-trunked. The warbler collects the strips of bark shedding from Ashe juniper to construct their nests.
