RangeRufous-collared Sparrow has one of the widest ranges of any New World songbird. It occurs from southern Mexico through Central America, across most of South America, and all the way to Tierra del Fuego. In Costa Rica, it is found nationwide, from sea level to high elevations, including the Central Valley, Pacific lowlands, Caribbean lowlands, and even cooler highland areas.
BehaviorUsually seen alone or in pairs, sometimes in small loose groups. It feeds mainly on seeds and grains, while also supplementing its diet with insects and other small invertebrates, especially during the breeding season.
ReproductionBreeding occurs throughout much of the year, with peaks during the rainy season when food is most abundant. Rufous-collared Sparrows form monogamous pairs, and both parents participate in nest building and chick care. Clutch size usually ranges from 2 to 4 eggs. Fledglings leave the nest after approximately 10–12 days, but remain dependent on the parents for a short period as they learn to forage independently.

🎁 Fun Fact:
Rufous-collared Sparrows have regional “dialects” — birds from different areas sing slightly different versions of the same song, much like local accents.
⚠️ Advice:
Listen for its clear, whistling song in the early morning. Rufous-collared Sparrows are approachable, but observing quietly will reveal natural behaviors like foraging and singing from low perches.
