Spring is a great time to track the activities of birds along the migratory path in the Highland Lakes. Activities for birdwatchers include:

• 13th annual Balcones Songbird and Nature Festival, April 26-29, Balcones Canyonlands National Wildlife Refuge. Nestled on 23,000 acres on the Edwards Plateau, the refuge straddles Burnet, Travis and Williamson counties. Visitors can catch a glimpse of the golden-cheeked warbler and the black-capped vireo, both endangered songbirds that nest exclusively six months out of the year in the refuge. For a listing of daily activities during the festival and through the spring and fall, go to www.friendsofbalcones.org/festival. The park has access areas on RR 1431 midway between Marble Falls and Lago Vista and also on FM 1174 between Smithwick and Bertram.
