Laughing Falcon (Herpetotheres cachinnans) lives in tropical forests across Central America. It feeds on snakes and lizards. Its conservation status is Least Concern.
Fascinating facts about the Laughing Falcon
- At just 45 to 56 cm long with a 79-94 cm wingspan, males weigh 408-686 g while females tip the scales at 590-800 g. This size lets it maneuver like an Accipiter hawk, with short, rounded wings and a long tail that aid quick, low-level flights through forest edges, letting it surprise snakes from perches.
- The bird's diet is a snake-snatching specialist: it regularly attacks venomous coral snakes and even large snakes, dropping them from a perch with an audible thud. Small snakes are swallowed whole, while larger ones are carried in one foot and torn apart.
- Breeding timing shifts with latitude: in Guatemala and Costa Rica eggs appear in February-March, while in Venezuela breeding activity is reported in September, Argentina in January, southwestern Colombia in May, north-western Peru in July, and central Brazil in September. Nests are placed high, up to 30 m (100 ft) above ground, in tree cavities, rock crevices or abandoned raptor nests, and the female incubates a single (sometimes two) egg for 40-45 days before fledging occurs 55-59 days after hatching.
- Unlike many forest raptors, the laughing falcon thrives in disturbed landscapes: populations are larger in secondary forests and open treed areas than in pristine primary forest. Its range stretches from sea level up to 2,400 m (7,900 ft) in Colombia, though it usually stays below 800 m (2,600 ft) in Ecuador and 1,000 m (3,300 ft) in Peru. This flexibility lets it occupy almost every mainland South American country except Chile and Uruguay, plus Mexico and Central America.
- The bird's name comes from its laugh-like call: a long, rhythmic series of hollow notes that start with a bubbly laugh and rise into a "wah-koh" phrase. Pairs duet for minutes at dawn and dusk, a behavior that cements pair bonds. Indigenous peoples hear this call and believe the falcon can cure snake bites, even mimicking its sound in healing rituals, showing how its vocal identity intertwines with human culture.
