Earlier this evening (Thursday, May 3rd), I birded the referenced location from the parking lot up to upstream of the dam and back. The following birds were observed during my hike:
PRAIRIE WARBLER-while observing the 3 owlets in the second Great-Horned Owl nest, I clearly heard the distinct song of a Prairie Warbler coming from a nearby tree. I stood still and listened while it sang 3 stanzas of its song. I could not visually locate it nor did it sing again for the next 20 minutes or so that I looked for it. I have seen and heard numerous Prairie Warblers while living in Ohio, and there was no doubt that I heard one. On my way back to the parking lot, I tried to look for it again in the same area for another 15 minutes but again no luck.
Townsend's Warbler-2 males
Bullock's Oriole-7 males and 2 females
Willet-2 in flooded Jarrard Ranch field
White-Faced Ibis-35 in the same flooded field
Western Screech Owl
Great-Horned Owl-2 nests with 3 "branching" owlets each and the respective mother nearby
House Wren-about 25
American Robin-10 including 1 "piebald"
The parking lot for Carson River Park is off of Carson River Road (which runs off of E. Fifth Street) just before the bridge over the Carson River in the eastern part of Carson City.
