Costa Rica Hummingbirds, February (1 Viewer)

[Wirral Rover]

Hummingbirds are so amazing.

I thought I knew these at the time, but now I cannot ID them! The colours change with the light etc. so do not always look the same as the field guides.

Any help appreciated.

I am no expert on hummingbirds, but was recently in Costa Rica, and some of these hummers look familiar. I suggest Green-crowned Brilliant for 1 and maybe 3. No. 2 looks like a Coppery-headed Emerald. Not sure about 4.

Agree 1 = green-crowned brilliant, 2=coppery-headed emerald.

Suggest 3) is immature male Talamanca hummingbird. This because: we can see some evidence of the brilliant greenish/bluish throat gorget, bill shape [strong, straight], indication of white post-ocular spot, [I think without stretching too much] indication of dark purple feathers of forehead.

For 4), suggest Blue-chested hummingbird. It's a bit like this one:

without any red in the bill [they can have all-dark bills], and with muted copper tones to the rump area [in the OP photo appearing dull brownish]

Thank you to everyone for your feedback. :t:
