If you look close, you can see the grooves in his bill. And yes, there is a “Smooth-billed Ani” found only in the South Pacific of Costa Rica, while this one can be seen in the northern 2/3 of the country. They are semi-regular in my neighborhood and you can see my other photos of this bird in my GALLERY: Groove-billed Ani, Crotophaga sulcirostris from several locations in Costa Rica. Here’s 3 shots from my garden 2 days ago . . .
¡Pura Vida!
