Identifying the Wedge-tailed Grass-Finch
Imagine a sparrow dipped in sunshine. The Wedge-tailed Grass-Finch is roughly 7.4 inches long, with greenish upperparts streaked with dusky brown. Look for a flash of sunshine yellow – the hallmark stout bill. The underparts are a clean buff, contrasting beautifully with the darker back. But the most striking feature is undoubtedly the tail – long, graduated, and ending in sharp or wispy tips, like a miniature kite tail.
Finding Your Feathered Friend
While the Wedge-tailed Grass-Finch has a surprisingly large range across South America, in Costa Rica, you’re most likely to find them in the lowlands and foothills. They favor dry savannas, seasonally wet grasslands, and even slightly degraded former forests. So, keep your eyes peeled as you explore the base of our mountain range or take a day trip to nearby pastures.
A Grassland Specialist
The Wedge-tailed Grass-Finch is a true specialist, perfectly adapted to its grassy habitat. Their thick yellow bills are perfect for cracking seeds, their primary food source. They forage on the ground, hopping and flitting between grass stalks, their long tails acting as rudders for quick changes in direction. You might see them in pairs or even small groups, their soft chip notes a subtle addition to the grassland symphony.
A Vital Part of the Ecosystem
Small as they may be, Wedge-tailed Grass-Finches play a crucial role. By consuming vast quantities of seeds, they help to control weed populations, promoting healthy grasslands. In turn, these healthy grasslands provide essential habitat for a variety of other animals, creating a balanced ecosystem.
A Birding Adventure Awaits

With a little patience, you might be rewarded with a glimpse of the Wedge-tailed Grass-Finch, a tiny testament to the wonders of adaptation and the intricate web of life in Costa Rica.
