This small flycatcher, barely 10 cm tall, is a regular resident of the Costa Rican highlands, including the lush mountain range that embraces our retreat. While not as vibrant as some of its rainforest cousins, the Northern Bentbill has its own charm.

A Clever Hunter with a Curved Bill

As its name suggests, the Northern Bentbill possesses a slightly curved upper bill. This unique adaptation helps it in its tireless pursuit of insects. Perched on a low branch or flitting among the leaves, it keeps a keen eye on its prey. Once spotted, the Northern Bentbill launches into a short, acrobatic flight, capturing its target with impressive precision.

Its diet consists mainly of flies, beetles, and grasshoppers. They are extraordinary insectivores, maintaining the balance of the forest ecosystem by controlling insect populations.

A Master of Many Habitats

The Northern Bentbill is not picky about its home. You can find it in various habitats, including:

• Subtropical or tropical dry forests: These are areas with less rainfall, often characterized by shorter trees and thorny vegetation.
• Subtropical or tropical moist lowland forests: These rainforests feature a dense canopy and abundant undergrowth, offering the Northern Bentbill a variety of hunting grounds.
• Heavily degraded former forests: While they prefer pristine forests, Northern Bentbills can adapt to areas that have undergone logging or agricultural conversion. This adaptability makes them relatively common birds in Costa Rica.

A Melodious Resident

While not known for elaborate songs, the Northern Bentbill contributes honorably to the morning concert. Its main call is a sharp, quick chirp, often described as a “chip-chip-chip” or a “treet-treet-treet.” It also has a short, whistled song, more melodious but less frequent.

Observing the Northern Bentbill

Due to its small size and preference for the lower canopy, spotting a Northern Bentbill can be a challenge. But with a bit of patience and some helpful tips, you might get lucky:

• Listen for its calls: The small, sharp chirp is the clue. Once you hear it, focus on the area and see if you can spot any movement.
• Early morning is the best time: Bird activity is generally more intense during the first hours after sunrise. So, grab a cup of coffee on the porch and pay attention.
• Look for movement in the lower branches: Northern Bentbills tend to perch on low branches or flit among the undergrowth. By scanning this area, you’ll have a better chance of spotting one.

Keep in mind that birdwatching requires patience and practice. But with a little effort, you might find yourself gazing at this small hunter, a vital element of Costa Rica’s mountainous ecosystem.
