Hi there,

Vancouver, Stanley park 20.08.18
Just took a picture of this little guy and I am not sure whether is a Cassin or a Huttons, although I lean towards the second option I would like to know how I can be sure about the ID (if this picture is enough).

Thanks

Hutton's, there is virtually no contrast that I can see on the underparts (vent, under tail, flanks, belly all seem blended together as one brownish yellow/green color) which is fine for Hutton's and points away from Cassin's.

Thank you for your reply, I think that the belly color as a feature is difficult to evaluate. There is a very blurred twig across the image that makes that part of the image more brownish, do you have other features I can rely on?

Thanks

To add....the legs bluish grey, the pp shorter than you’d expect on Cassin’s, the eye-ring narrowing top and bottom...on Cassin’s it would be consistently clear and contrasting as with the lores...from my perspective it looks more like a kinglet (which it isn’t) than Cassin’s.

Cheers
