First Purple Martins

On my way to lunch today I saw two male Purple Martins over Anderson Mill Road between Broadmeade and Parmer. These are the first I've seen in the NASWC area this year, although Purple Martins have been seen around Austin for the past few weeks. Like other North American swallows, these birds are only around in the summer. The males are the first to return, hoping to find an available martin house for the breeding season. Someone has put up at least one martin house along this stretch of road, so maybe these birds were eyeing it.
