IOS Field Trip Report by Tyler Funk

Scoping for Snowy Owl

Scoping for Snowy Owl

On January 7th, six hardened IOS members (Ted Wolff, David and Dale Kalina, Susan Zelek, Linda Foster and Tyler Funk) set out for a field trip this past weekend in search of Prairie Falcons and waterfowl. Leaving the house at 6:15am, my vehicle thermometer read -2° F. However, the sky was mostly clear and the air felt fresh as we set out to begin the day. Our first target was the Prairie Falcons. These birds have proven difficult to find this winter due to the extensive fall plowing that took place in the area. Finding a corn stubble field suitable for food and cover is not easy this season. Rough-legged Hawk, Merlin, Short-eared Owls and Northern Harrier are all relatively easy finds here most winters and they too are tough to locate this season. Another target in the area was a Snowy Owl which was found on January 6th about a mile east of what we call “Falconville”. We began driving a grid which allowed us to systematically check the area. This paid off with an early morning look at a Snowy Owl, but once again, the Prairie Falcon was a scratch. The group then made a sparrow walk through Larry Closson Habitat Area (aka Hickory Ridge) which yielded some nice sparrows for the day list.

After a drive to Universal Mines, the thawed out group spent the next few hours attempting to estimate waterfowl numbers that blanketed the quarry. The waterfowl numbers here is always a highlight and the numbers of Trumpeter Swans is quite impressive. It certainly rivals any other spot in the state for sure. The group returned to the Prairie Falcon area, where we met up with Travis Mahan, Colin Dobson, Ron Bradley, Corey Lange and Tony Ward. The added eyes were welcome, but the Prairie Falcon remained absent. Those that remained to dark were rewarded with a nice sunset view of the Snowy Owl.
