I headed to NE Colorado today, birding the big reservoirs with John Vanderpoel. Goose numbers were massive; we easily saw over 100,000 geese of five types between those along I-76 in Morgan County and huge flocks at Jumbo, North Sterling and Prewitt Reservoirs. Snow, Cackling, Ross's, Canada, and Greater-white Fronted in order of abundance. The white geese were all along I-76 in Morgan, at Prewitt (Washington) and in the Sedgwick side of Jumbo. GWFG noted included 7 in a field at the corner of Red-Lion Road and US 138 in Logan, 5 each at Jumbo (Sedgwick) and Prewitt (Washington)
What we missed included any loons or scoters. We also failed to find recently reported rarities like Black-legged Kittiwake and Snow Bunting.
Unusual birds included a single Sandhill Crane flying right along I-76 in Morgan County west of Wiggins and a single Common Redpoll in the shelter belt along the road at the west entrance to North Sterling State Park. Prewitt (Washington) also had three Bonaparte's Gulls and an Iceland (Thayer's)
North winds were howling at Jumbo and North Sterling, but by the time we made it to Prewitt conditions had calmed down noticeably.
