The distinct small patch behind the eye,
on this bird and some of SIMON's photos of
related species is Naked or Feathered?

DANSK
Nøgen plet lige bag øjet?

- Nyd lige fjerpragten omkring næbbet!

Various species of many hummingbird genera have a small light colored spot behind the eye. The dot is usually made up of small light colored feathers. Whether some species have dots of colored skin or not is unknown to me.
From an evolutionary viewpoint the spot is probably a primitive character that increase fitness given the great presence in the hummingbird family.
But what is the significance of the spot?

Danish
Forskellige arter af kolibrier i mange forskellige slægter har en lille lysfarvet plet bag øjet. Pletten består sædvanligvis af små fjer. Jeg er ikke klar over om der er findes arter hvor pletten består af farvet skind.
Man må formode at det er en primitiv karakter siden den forekommer i så mange forskellige slægter, samt at den øger fitness siden den findes hos så mange arter.
Men hvilken gavn giver prikken?
