Golden-winged Warbler

Golden-winged Warbler

Without a doubt, one of the highlights of our recent work in Costa Rica was the recapture of this Golden-winged Warbler, which was banded last year in the same area it was caught this year, near Rara Avis Rainforest Lodge. Since we last saw it in March of 2016, it undoubtedly traveled back to its breeding grounds somewhere in North America and hopefully managed to find a mate of its own species. Golden-winged Warblers are suffering from dramatic declines throughout their range, and are increasingly hybridizing with closely-related Blue-winged Warblers. As a result, this species is at serious...

Spring Peepers

Spring Peepers

Spring Peepers are a type of small tree frog. Truthful to their name, they emerge from hibernation in early spring. Soon after, the males – often hundreds at a time – will take over wetlands and call on warm and rainy nights to stake out a territory and attract a mate. Their surprisingly loud “peep” calls are usually produced from a safe location hidden in dense vegetation, and it can be difficult to spot them. An inflatable vocal sac on their throat serves as an amplifier, which allows them to call very loudly. The sound produced by a chorus of these inch-long frogs can be truly deafening...

Downy Woodpecker

The Downy Woodpecker (Picoides pubescens) is an industrious little bird that frequents parks and woodlots throughout much of North America. While often spotted at backyard feeders with similarly sized chickadees and nuthatches, this black-and-white woodpecker is also at home on tiny branches where it can be seen acrobatically foraging for insect larvae. Roger Tory Peterson described this bird’s call as “a rapid whinny of notes, descending in pitch.” Keep an eye and an ear out for this charismatic little bird; its striking plumage, shrill song and tree-trunk tapping should...

Winter Blues

Blue Jays (Cyanocitta cristata) can look so vibrantly blue on sunny days, but blue coloration in animals is very rarely created by blue pigment. Instead, their stunning hues are created by refractive colors of light, breaking on microscopic structure of the feathers. Minute barbs on their feathers are specially modified to scatter light in a way that makes them appear blue, rather than showing the brown melanin that their feathers are colored with. Yes, Blue Jays are not actually...
