Maybe not a Cassin's Kingbird at Heron Pond in Denver

[Eric Dinkel]

Hi All,

I reported a Cassin's kingbird yesterday evening at Heron Pond in Denver. The dark grey stood out when I first saw this bird and the contrasting white malar had me convinced. I was pretty excited. But after consulting with more experienced birders I realized I didn't check the tail for subtle white tips. As that seems to be the diagnostic feature, I am taking away my id (replacing it with Cassins/Western). Just wanted to report in case someone was going to go chase after it. Although a Yellow throated vireo was reported there this am, so may be worth the trip! 

Cheers,
