Elaenias around Turrialba

Birds for Beer

Elaenias are medium-sized flycatchers found only in the Americas, and then only from Mexico southwards. The name means ‘of olive oil’ and refers to the general colour of their plumage. Identification of many of the 21 species can be difficult, but in the Turrialba area only two of the four species that occur in Costa Rica are really common, the Yellow-bellied Elaenia (Elaenia flavogaster) and, at higher elevations, the Mountain Elaenia (Elaenia frantzii).

I do have two isolated sightings from as high as 2200 m at Llano Grande, between the Turrialba and Irazú volcanoes.
