Aug 25, 2012: Least Tern
Least Tern on mudflat in southwest corner of the south lake, 8/24/12 (Wolf Oesterreich)
This Least Tern was found Friday afternoon and represents a new species for the Park List (#259). According to "The Birds of Story County, Iowa", 3rd Edition (July 2001), by Stephen Dinsmore and Hank Zaletel, this bird may represent only the second record for the county (1st = 13 June 1990 at Colo Bogs). The bird appears to be loosing its breeding plumage. The tern was found at 1420 on a mudflat located in the SW corner of the south lake (where the south wetland complex drains into the south lake). I managed to extract two of the tripods legs when it flew off for the first time. However, within minutes it was back and I was able to obtain a few (not very clear) digiscoped photographs. After several more minutes it took flight again and I never saw it again.
