How to Identify Buckley's Forest Falcon Feathers

What Buckley's Forest Falcon's Feathers Look Like

Buckley's Forest Falcon is a secretive rainforest raptor of the western Amazon, and its feathers reflect a life spent hunting inside dense understory rather than open sky. Unlike a peregrine's blade-like wings, this bird has short, broad, rounded flight feathers built for quick bursts and tight turns between tree trunks, not high-speed stoops. Primaries and secondaries are dark slate-gray to blackish above with little contrast, while the underside of the flight feathers shows fine pale barring.

The tail is unusually long relative to the wings, a signature forest-falcon trait, and shows several bold black bands alternating with narrower white-to-gray bands, ending in a white tip. Body and covert feathers are dark slaty gray to blackish on the back and crown, transitioning to whitish underparts finely barred with dusky gray. Down and semiplume feathers from the flanks are soft and pale, often washed with a faint buff tone near the skin.

Step-by-Step: Is This Feather From a Buckley's Forest Falcon?

• Measure it. Flight feathers typically run 15–22 cm; a full tail feather can reach 20–28 cm, notably long compared to the wing feathers.
• Check the shape. Look for a rounded, blunt tip rather than a tapered point — forest-falcons have paddle-shaped wings, not pointed falcon wings.
• Look for tail barring. Several wide dark bands crossing a pale ground color, ending in a whitish tip, is a strong clue for a forest-falcon tail feather.
• Inspect the underside color. Pale grayish-white with narrow dusky bars on covert or belly feathers points to this species rather than a solid-colored raptor.
• Consider the shaft. The rachis is stout and dark on flight feathers, pale on body feathers — typical of a mid-sized forest raptor, not a small songbird.
• Think about where you found it. A feather turning up on the floor of intact terra firme rainforest, far from open country, supports a forest-falcon rather than an open-country hawk or falcon.

Similar Species & How to Tell Them Apart

The closest look-alike is the Barred Forest-Falcon, which is smaller and shows finer, more numerous barring on the underparts and a proportionally shorter tail. The Collared Forest-Falcon is larger with a bolder, more contrasting black-and-white tail pattern and often a pale collar-like band on the nape that can leave whiter nape feathers. Slaty-backed Forest-Falcon is very similar in size but tends to show broader white tail bands. Away from forest-falcons, true forest hawks like Barred Hawk have much broader, more heavily barred underwing feathers and a stockier feather structure. If the feather is pointed and blade-like rather than rounded, you are likely looking at a true falcon (Falco) rather than any forest-falcon.

Where & When You'll Find Them

Buckley's Forest Falcon lives in the interior of lowland Amazonian rainforest in Ecuador, Peru, and adjacent Brazil, rarely straying into secondary growth or forest edge. Because it is a year-round resident of stable tropical forest, molt is not tightly seasonal the way it is in temperate raptors — feathers can be dropped at almost any time of year, though a slightly higher turnover often follows the breeding season. Feathers are most likely to be found on the forest floor beneath a favored perch, near a plucking site after a kill, or close to a nest cavity in a large tree.
