At first glance, it might be mistaken for a swallow, but the Chestnut-collared Swift (Streptoprocne rutila) belongs to the apodidae family. Slightly larger than a chimney swift, these birds are made for life in the air. Their long, pointed wings and deeply forked tail give them incredible maneuverability, making them a marvel to watch as they dart and zigzag through the mountain air.

Identifying a Chestnut-collared Swift

At first glance, these swifts appear almost completely black. But look a little closer, especially in good light, and you can glimpse their distinctive feature: a subtle chestnut collar. This reddish band adorns the necks of adult swifts, while younger birds lack this distinctive mark.

While gliding through the air is their specialty, occasionally Chestnut-collared Swifts can be seen perched on cliffs or broken branches, clinging with their strong legs. But don’t expect them to stay still for long. These birds are almost constantly on the move, hunting insects on the wing.

Listen to the Crackle

While their visual beauty is undeniable, the Chestnut-collared Swift also possesses a unique vocalization. Their call is a loud, crackling chatter that some describe as the sound of electricity passing through wires. This distinctive sound is a sure way to identify these swifts, even when they are just tiny dots in the vast blue canvas of the mountain sky.

Hábitat y Costumbres

The Chestnut-collared Swift is a bird of the foothills and mountains, although it can occasionally be seen even in the lowlands. It feels most comfortable in open areas with some scattered trees, cliffs, or rocky walls. This makes it a regular spectacle at our mountain retreat, where they gracefully navigate the valleys and ridges.

These swifts are social creatures, often seen flying in large flocks. They may even associate with swallows and other swift species, creating a fascinating aerial ballet.

A Glimpse into the Life of a Swift

The Chestnut-collared Swift spends most of its life in the air. It catches insects on the wing, using its sharp eyesight and maneuverability to snatch its prey mid-flight. It even drinks, bathes, and breeds while flying: a truly aerial existence.

The breeding season for the Chestnut-collared Swift usually occurs between March and August. They build their nests on cliffs or in building crevices, crafting a cup-shaped structure from twigs and leaves. Both parents take turns incubating the eggs and feeding the chicks.
