Can't be much else but why does it have a blue eye ring?

Not been to CR (yet) : presume we're sure it's not male black - throated Trogon ? Quote from neotropical birds (Cornell) : "Male Gartered Trogon is similar to the male Black-throated Trogon but the latter has greenish iridescence in the neck and chest and a pale blue eye-ring, in contrast to the Gartered’s violet-blue iridescence and yellow eye-ring (Ridgley 1974)"

I don't know my Trogons, never seen one in person, but is it possible it is hybridised with Black Headed or Black Throated? I don't know ranges since I don't have a book on hand that covers the area. It does look a little like the Black Throated in this picture here.

I think you have it Fern, the bill seems yellow as well making it Black-throated but the blue irridescence put me off and there seems to be more of a white breast band than I'd expect on B-throated?

Black-headed is out of range Sasquatch.

Mark it down as experience!

Yeah it does look like. Pretty!

Just been looking at Surfbirds gallery, there are a couple of birds labelled as Black-throated that look like Black-throated but have a yellow eye ring?

Look at the one by Pete Morris.

Some Black-throateds (races?) do show yellow eyerings, I've seen a small few, kind of confusing actually.

That is confusing, thanks Motmot.

I think the original pic is a black-throated seen under lighting that makes the iridescence look bluer than normal, possibly confounded by a photo that did not get the white balance quite right.

Did you look at the pics of Black-throated on Surfbirds?
