Loch Kilpatrick, Glenn Walbek and I did a two day birding trip through
northeast Colorado on Thursday and Friday. Prerwitt Reservoir water
level has dropped noticeably in a week with good mudflats now in
evidence. The best landbirding there was along the inlet canal. Be
prepared for mosquitos. Activity below the dam was slow but it was
also gettng hot. Interesting species were the movement of America
Redstarts with 10 over several locations. Jumbo Reservoir also has
good mud but there were amazingly very few shorebirds. Bonny SP and
SWA was inundated with Red-headed Woodpeckers. There was
conservatively 80 individuals.

Bonny - We asked about the status of the reservoir. It is scheduled to
be completely drained by the end of the year. The campgrounds will be
closed in October. It will remain open as a State Wildlife Area with
no Park facilities remaining open. The status of the Visitor Center is
undecided, but one sign is the usual books and other items for sale
are basically nonexistent on the shelves.
Wild Turkey 100, none was consumed by participants
