[cobirds] Chestnut-sided Warbler continues in Washington Park, Denver County

This apparent first-fall female bird is confiding and was the 3rd bird I saw after getting out of my car

just before noon today. It was moving about in the trees, about 8-20 feet off the ground and 

appeared without any pishing, but was very attracted to quiet pishing later on.

I followed it for 20 minutes, then the flock moved away. 

I was able to see not only the obvious marks, like the "lime green" upper-parts, yellow wing-bars, (these

are notable, as wing-bars on most Colorado warblers are white), the white eye-ring 

and clean white underparts, but was also able to glimpse small areas of light

yellowish near the vent and notice the posture of cocking the tail up. There was no chestnut at all on the underparts, fitting

best with first fall females shown in field guides. The yellowish wing-bars alone were worth the trip.

The best place to park is along the extension of Mississippi Avenue as it continues west

into the park from South Franklin Street. From there check the trees near the park 

bench that is on the NE corner of Grasmere Lake. This is near the Bowling Green also.
