This Willet (a shorebird) was found along the shore of the north lake (NE corner) on Monday (March 29th). The coloration is rather drab, but once in flight, the black-and-white pattern is quite distinctive. 3/29/13 (Wolf. Oesterreich)
A total of 122 avian species was recorded this month, ranking this month as the highest April among 16 years of records. Two species, Golden Eagle (#261) and Swainson’s Hawk (#262), were added to my Park List. So far, a total of 137 species have been recorded this year.
Based on citations in the 3rd Edition of “The Birds of Story County, Iowa,” by Stephen J. Dinsmore and Hank Zaletel (2001), plus my personal updates to the records, the 250+ Pied-billed Grebes sighted on the 22nd may set a new peak count record for Story County (former record of 97 set on 6 Apr 2011 at Ada Hayden HP). The single Osprey on the 2nd may set a new extreme early Spring record (former record set on 5 Apr 2006 at Ada Hayden HP). Other potential new extreme early Spring records include 1♀ Wilson’s Phalarope on the 12th (former record set on 22 Apr 1984 at Colo Ponds), 1♂ Yellow Warbler on the 29th (former record set on 30 Apr 1986 at Ames, 1988 at Hendrickson Marsh, & 2001 at my backyard), and 2 Lark Sparrows on the 21st (former record set on 30 Apr 2005 at Ada Hayden HP). Rare migrants in Story County include the Swainson’s Hawk and Marbled Godwits. The Golden Eagle is an accidental record.
