After going to Mueller Lake Park yesterday afternoon and hearing the Least Bittern found and reported by Mollie Kloepper I decided to go back this morning and try again. I showed up at first light (6:15ish) and quickly heard the bittern calling. After a good while of searching I located it in the vegetation with the spatulate leaves and purple flowers (I'm sure I should know what it is, but don't). After locating the bittern I watch it forage for 15 minutes or so then it moved up in the vegetation and out in the open. It preened and called while I watched for 20 more minutes. It was still doing this when I left. Anyone wanting to find/observe this bird should stay across the water from it and scan the vegetation. It's location was well described by Mollie as "the part of the pond nearest to Zach Scott St. [SW portion of pond] on the side away from Airport Blvd [east]." Observation is good from the side nearer Airport (west) where the little concrete pad goes into the water. Also of interest right there is a family of shrikes with adults feeding fledglings. I make the above recommendation because there is very little appropriate vegetation lining the shore and it's quite dense. The chance of disturbing the bird is likely high and the chance of seeing it from the side it's on is quite low I think. Viewing from across the narrow water was wonderful, though, and it clearly preferred the relative comfort of the water side seemingly unconcerned by the morning walkers. Oh, and the Purple Martins put on quite a spectacle swarming over the water in their morning dispersal from the Highland Mall roost. There were several thousand birds flying over while I watched the bittern, but I was more in bittern mode than my usual summer martin counting mode. Thanks, Mollie for finding and reporting this wonderful bird. Cheers, Jake McCumber Austin
