Boulenger’s Long-snouted Tree Frog (Scinax boulengeri)

There are three Long-snouted Tree Frog species in Costa Rica, with the Boulenger’s and Olive being both widespread and common accross wet lowlands in the country, and the Dry Forest species being common in the northwestern region (Guanacaste). The Boulenger’s is mostly light brown, including the iris, with small patches of green and darker brown that provides better camouflage. It is colloquially known as “Rana Lagarto” (crocodile frog) in Costa Rica due to its unusually long snout.

It is arboreal and nocturnal, and males frequently call with their body upside-down during the wet season. To help hold this position, the innermost finger can be rotated up to 90 degrees, essentially pointing upwards, which provides a better grip on smooth surfaces like tree branches and trunks. The skin is granular, which might put off some people that feel that its appearance is gross. Yet amphibians have a very important role in wet ecosystems, as some of the insect prey they consume might develop into plagues if unchecked. Most amphibian species have been battling with declining populations, and protecting them from extinction is one of our biggest challenges.

Green Honeycreeper (Chlorophanes spiza)

Ever since I first see the Red-legged Honeycreeper, I inmediately knew I was seeing one of the most gorgeous species Costa Rica has. Then I met the Green Honeycreeper, and I stood delighted. The male has a striking combination of dark green body, deep black hood, bright yellow bill and dark red iris, which just looks amazing, even when wet. In fact, I would say a wet male screams Rain forest, that’s enough to love it. The female is not as exotic, however the green color of their feathers is so bright as to defy belief. I also spotted this species in Colombia, which seemingly looked more turquoise than green.

Social Flycatcher (Myiozetetes similis)

The Social Flycatcher is part of the family of “Pecho Amarillo” birds, as are locally known in Costa Rica. It is pretty difficult to identify since the birds all look alike, but they can be identified relying on size, song and head markings. My parents say that this species should be called “Shakira”, an onomatopoeic interpretation of their sound. They are almost identical in size and shape to the Gray-capped Flycatcher, however their song is very different, and the Gray-capped not just has the different head color, it also shows erect feathers which the Social does not.

Black-cheeked Woodpecker (Melanerpes pucherani)

This is medium sized woodpecker that can be found in the Caribbean and northern part of the country. The male has red back and top of the head, with a yellow patch in the front, while the female has whitish top of the head (nape). Both have black cheeks, which give this species its name. Other notable features are its black wings with white dots, black back with white barring, yellowish flanks with black barring and red belly, which gives the bird a very contrasty look. It’s call is a piercing chirrr, chirrr, chirrr that can be heard from afar and make identification of the species easier.

Like most woodpeckers, they make holes in trees for nesting, which are then reused by other species, hence their success can indirectly impact population sizes for other species. Many times the nests that they empty are reused by similarly sized birds to construct theirs, with Emerald Toucanets as one such example, but even some owls will make use of them. It’s not uncommon to see either the male or female inside the hole, with just the head out, watching out for potential predators as they keep their eggs or chicks safe inside. Something more peculiar is seeing these birds pecking at public lampposts made out of concrete, I have not yet deciphered why would they do that. On feeders, they like to eat papaya, but they will also catch small insects for food.
