Hardberger Park is an important stop for migratory birds. We have seen some unusual migrants in the park including the sage thrasher, golden-cheeked warbler, warbling vireo, blue-headed vireo, and one of my favorites, the blackburnian warbler. Bird sightings for the park are documented on ebirds. So far, 70 different bird species have been documented on the Blanco Road entrance or north side of the park and 59 species have been documented on the NW Military entrance or south side of the park.
