We saw a lot of birds in CR obviously. Some of them were left unidentified with views too brief or too dim. A couple (the first yellow-headed caracara and the spadebill) were mis-identified. These three seem like they shouldn't be as hard as they were.
The first is a small flycatcher near the Tarcoles boat launch. We were hoping for Panama Flycatcher, a myarchid class bird when this one flew up. It flew away in seconds. I'm fairly confident it's Greenish Elaenia based on the dark eye, narrow bill, pale base to the lower mandible, and lack of wingbars (Yellow-olive Flycatcher, a bird that never quite looks like the books to me, would have opposite features).
Next is a female becard from the same patch of forest.
Finally is a small group of ground-doves from Guacimo Rd. There was a pair of Ruddy Ground-doves.
And there was a 3rd bird, pictured here. The female ruddy is on the left, but is the bird on the right Common Ground-dove or Plain-breasted Ground-dove?
