momoto ceja turquesa

Just read in Wikipedia - "Unlike most bird species, where only males express elaborate traits, the Turquoise-browed Motmot expresses the extraordinary racketed tail in both sexes. Research indicates that the tail has evolved to function differently for the sexes. Males apparently use their tail as a sexual signal, as males with longer tails have greater pairing success and reproductive success. In addition to this function, the tail is used by both sexes in a wag-display, whereby the tail is moved back-and-forth in a pendulous fashion. The wag-display is performed in a context unrelated to mating: both sexes perform the wag-display in the presence of a predator, and the display is thought to confer naturally selected benefits by communicating to the predator that it has been seen and that pursuit will not result in capture. This form of interspecific communication is referred to as a pursuit-deterrent signal."

Never would have thought it was a shadow - but keen eyes and good thinking Ava and Ismael. Strange tail.

yes it is a shadow of the branch above

Very good point. However, after reading your comment, and looking at the possible Motmot species in Costa Rica, this must be it. If you look closely, there is actually a good chance that strong black band across the shoulders is actually a shadow. :)

Ah ha! That's a shadow! i think it is superciliosa!

Does Eumomota superciliosa have that strong black band across the shoulders? That is what kept me from suggesting it...

I see what you mean it resembles a Eumomota sp. but I haven't found it...

It's some kind of racquet-tail perhaps but i can't find a perfect match.

of course bee eaters are "old world" though

looks like a cross between a bee eater (Merops sp.) and Momotus sp.

Beautiful bird, & such unusual tail feathers!
