A hummingbird near Santa Elena, Costa Rica, 23 January 2004.
Someone suggested it was a Buff-tailed Coronet, but now I rather think it is a White-tailed Emerald.

- I'd say neither: to find the BTC in Costa Rica would be odd (it does not even go as far N as Panama). Against both speaks the fact that the underparts are rather uniformly green; BTC has a scaled appearance, while WTE has a white lower belly. The best guess I could come up with is a Southern Stripe-tailed Hummingbird (Eupherusa eximia egregia) based on the combination of shape, all-green underside, not completely straight bill and rufous secondaries, but this may not be correct as identifiction of "green" hummers without a clear view of the tail is horribly difficult. The tail is what could speak against STH; if the shadow below the white is just that and not dark retrix tips and if the middle retrices are visible in the picture and not tucked away out of view, it can't be a STH. It could be a species of the "Amazilia" complex (Amazilia, Saucerottia, Agyrtria) or a Chlorostilbon true emerald, but the rusty-red secondaries and the overall shape, respectively, suggest it is not.
