how were they eliminated:
We could not think of any similar species to compare to this sighting.
When we first sighted the bird, we knew that it was not a familiar "more common" Utah species, so we immediately consulted our field guides. This bird looked exactly like the Chestnut-sided Warbler drawings in The Sibley Guide to Birds, and National Geographic Field Guide to Birds of North America. We could not find another warbler species which has the combination of features described above (white eye-ring, yellow-green crown, greenish-yellow back with dark gray streaking, light gray face and grayish-white underparts).
After we consulted the field guides, we relocated the bird and noted each of the features described by Sibley.
Upon returning home, we also compared the bird we saw to the photograph in The Audobon Society Master Guide to Birding, Volume 3, page 131. In our opinion, the bird we saw looked exactly like this photograph.
|Previous experience with this & similar species:||We have seen numerous Chestnut-sided Warblers at Point Pelee in Ontario, and in Texas. However, all of these sightings were in the spring, and were, therefore, breeding plumage adults.|
