Green Basilisk (Basiliscus plumifrons)

The Green Basilisk, also known as the Jesus Christ Basilisk due to its incredible feat to run on water, is one of the four species of the Basiliscus genus and of three species to occur in Costa Rica. The similar Striped Basilisk is brown with two yellow lines that run one through they, and a thicker one from below the eye, both ending in the upper portions of the back.

The male has a big crest that protudes both on the head, back and tail, which can be raised to signal that it is angry or defending its territory. Most of its body is green with light blue spots around the back, a color pattern that lets it camouflage very easily in foliage and vegetation, particularly during the morning when they bask in the sun to warm up their bodies. The female shows a lighter shade of green than the male. Their eyes are bright yellow. Both their fingers and toes are very large, with scales that can be extended, increasing the effective surface area of their feet and enabling them to run over water for short distances, up to 20 meters.

Striped Basilisk (Basiliscus vittatus)

The Common Basilisk, also known as the Jesus Christ Basilisk due to its incredible feat to run on water, is one of the four species of the Basiliscus genus and of three species to occur in Costa Rica. The similar Green Basilisk is (obviously) green, and the male has a big crest that protudes both on the head, back and tail, while the Striped Basilisk only has a crest on the head and a small ridge on the back.

It is brown with two yellow lines that run one through the eye, and a thicker one from below the eye, both ending in the upper portions of the back; this color pattern lets it camouflage very easily, particularly during the morning when they bask in the sun to warm up their bodies. Both their fingers and toes are very large, with scales that can be extended, increasing the effective surface area of their feet and enabling them to run over water for short distances, up to 20 meters.

Brown-crested Flycatcher (Myiarchus tyrannulus)

The Brown-crested Flycatcher is a resident species, member of the Myiarchus family, which is notably difficult to identify at a species level. The Brown-crested is found only in the northern Pacific area, up to about the Tarcoles river. It shares distribution with the Nutting’s Flycatcher, and are difficult to differentiate given its essentially equal coloration except for the rump; their song is an important trait to identify them. The Brown-crested is found in mangrove forest edge, whereas the Nutting’s is not. It was interesting to see this individual raising its crest, most probably a display to let us know we were in his/her territory.

Long-tailed Silky-flycatcher (Ptilogonys caudatus)

The Long-tailed Silky-flycatcher is an elegant bird that can be found in the highlands in Costa Rica. It’s long black tail contrasts with the gray and yellow body, ending with a yellow crest that is normally seen protruding from the head. The male is more colorful than the female, but overall they look similar and might be indistinguishable on bad lighting. Along the Black-and-yellow Silky-flycatcher, this species is part of a four species family around the world, with only the Black-and-yellow and the Long-tailed being present in Costa Rica, endemic to our country and western Panama.
