This location can be surprisingly birdy. Be sure to drive to the far end of the cemetery--away from Park Road 4 and the road/traffic noise--and watch and listen for birds.

Wintertime is a wonderful time to add lots of sparrows. 

If there has been any recent rains, the small pond/tank on the southwest corner of the cemetery should have water which may bring in water birds.

If you have time, walk the perimeter fence lines to see what you can find. 

This location might be well worth a stop after visiting the other hotspots along Park Road 4 and could be a wee bit more productive that Longhorn Caverns.

Winter sparrows (Lark, Vesper, Savannah).

American Pipits in the winter--be sure to look at the pipits to see if there might be a Sprague's in the mix. 

Black-throated Sparrow year round.

Water birds if there's any water in the pond. 

The road noise is much lessened when one gets further away, enhancing birding by ear. 

None. The walking is along the cemetery roads.

The cemetery roads might be suitable for a wheelchair or scooter. Feedback about accessibility from visitors would be much appreciated.
