A Loudlly singing Red-eyed Vireo was heard about 10:30 am in a cottonwood tree where 61st St. jogs east and crosses the St. Vrain river. Just north of the crossing, 61st becomes 63rd St., which then heads north. The area is ~0.5 mi. north of Hygiene Rd. and ~0.5 mi. south of McCall Reservoir. The tree was to the south of the road and south of the river.
I was on a field trip and could not stop to find it, but 3 of us in the car I was riding in heard it.
