Return to Rocky Mountain Arsenal, Adams County

September 27, 2009

Richard Stevens:

I returned to Rocky Mountain Arsenal with Rebecca Kosten this morning when they opened at 6:00 am. Winds were stronger than yesterday; 15+ mph, gusts to 21 mph.

A Long-eared Owl flew up about 6:31 am! No Barn Owls responded to my recordings this morning.

We then hiked to the Rod and Gun Club bird blind by way of the southern end of the Lake Ladora trail. A Black-and-white Warbler was in the cottonwoods below the Lower Derby Lake dam. No Cassin's Vireo was found today. One House Wren rattled along the canal below the dam.

At the R & GC bird blind we saw 6 Yellow-rumped Warblers fluttering about. A Palm Warbler was trailing behind them as they worked the trees and headed slightly north of the trail.

The number of Franklin's Gulls at Havana Ponds had doubled since yesterday. Still no Sabine's or Laughing Gulls in the mix. Today a Lesser Yellowlegs walked the northeast shore. I am positive that yesterday there was a Greater Yellowlegs, indicating a slight turnover in birds overnight.

I played Long-eared Owl recordings at four or five of the New Mexico Locust "groves" passed. Nothing responded at any of them. In the past, Long-eared Owls have responded even at 2:00 pm in the afternoon. Perhaps the winds had something to do with the lack of a response?
