As you delve deeper into the lush rainforests of Costa Rica, prepare to be serenaded by an unexpected symphony. Among the vibrant calls and melodic whistles, you might hear a sound that piques your curiosity – a series of squeaks and chirps that resemble a rusty hinge or a playful child’s toy. This, my friends, is the unmistakable song of the Sulphur-bellied Flycatcher, a stunning visitor gracing our mountain retreat for a part of the year.

While not native to Costa Rica year-round, the Sulphur-bellied Flycatcher is a short-distance migrant, gracing us with its presence from September to April. They breed further north, ranging from southeastern Arizona in the United States all the way down to Costa Rica. Come winter, they head to the eastern foothills of the Andes, seeking warmer climes in Colombia, Ecuador, Peru, Bolivia, and Brazil.

A Striking Beauty

The Sulphur-bellied Flycatcher is a true visual treat. Imagine a bird roughly 8.2 inches tall, boasting a plumage that is a captivating blend of patterns and colors. Its back and wings are a cool gray-brown, accented with dusky streaks. The flight feathers and wing coverts are edged in a crisp white, adding a touch of elegance. A flash of rusty brown graces the tail feathers, further enhancing the visual appeal.

But the star of the show, as the name suggests, is the belly. A vibrant yellow adorns the lower body, unmarred by streaks in the center, creating a beautiful contrast with the streaked breast and sides. The facial features are equally captivating. A bold black eyestripe creates a striking mask, offset by a prominent white eyebrow and a pale “mustache.” The large bill adds to the overall impression of strength and character.

Masters of the Hunt

The Sulphur-bellied Flycatcher is a true predator of the skies. They are most often spotted perched high up on an open branch, surveying their territory with a keen eye. Using the perch as a launchpad, they employ a technique called “hawking” to snatch their prey mid-air. With a burst of speed and agility, they snatch insects, their favorite meal. Their diet isn’t limited to just insects though, occasionally they’ll also indulge in berries and seeds.

Finding Your Feathered Friend

While the Sulphur-bellied Flycatcher can be found in various forested habitats throughout its range, here at our mountain retreat, you’ll find them gracing the woodlands of montane canyons, particularly at elevations between 1,000 and 2,000 meters. Keep an eye out for them perched atop tall trees, especially those with sycamores, a favorite amongst these feathered visitors in some parts of their range.

Listen for the Song of the Tropics

The Sulphur-bellied Flycatcher’s vibrant song is often the first clue to its presence. Those distinctive squeaks and chirps, reminiscent of a playful toy, are a delightful addition to the soundscape of the Costa Rican rainforest. So, next time you’re exploring the trails around our mountain retreat, keep your ears open for this unique melody. With a bit of patience and a keen eye, you might just be rewarded with a glimpse of this stunning visitor from the north.
