Immature is barred underneath with brownish nape. Adult is very similar to pale morph Collared Forest-Falcon but slightly smaller; ID is best confirmed by voice. Typical song of Buckley’s is “kawah, koh”, sometimes followed by a lower “koh” note. Usually stays inside forest and is infrequently seen.
