Lesser Nighthawk

The Lesser Nighthawk is a medium-sized crepuscular bird belonging to the nightjar family (Caprimulgidae). Celebrated for its intricate, bark-like camouflage, this bird spends its days resting horizontally on low branches or directly on the desert floor, blending seamlessly with the gravel and sandy soil. As dusk falls, it takes to the sky in a buoyant, erratic flight to hunt for flying insects. It is a classic summer resident of the arid southwestern United States and Mexico, often seen skimming low over desert scrub in search of prey.

Identifying the Lesser Nighthawk requires careful attention to its silhouette, wing markings, and flight style, especially to distinguish it from the closely related Common Nighthawk (Chordeiles minor).

• Wing Bars: Look for a pale, buffy-white band across the outer wing feathers. In the Lesser Nighthawk, this band is closer to the wingtip (distal) compared to the mid-wing band of the Common Nighthawk.
• Plumage: Cryptic gray, brown, and buff overall. The underparts are finely barred. Breeding males feature a prominent white throat patch and a white subterminal tail band, whereas females have a buff throat patch and lack the white tail band.
• Flight Silhouette: Broadly triangular wings with slightly rounded tips. Unlike the Common Nighthawk's sharp, powerful wingbeats, the Lesser Nighthawk flies with a more fluttery, low, and buoyant motion.
• Similar Species: The Common Nighthawk is slightly larger, darker, has pointier wings with a more centrally located, pure white wing patch, and flies with a much higher, more aggressive, looping path.

Lesser Nighthawks are birds of open, dry country and are highly adapted to arid and semi-arid environments.

• Primary Habitats: Desert scrublands, dry washes, mesquite grasslands, chaparral, and coastal sage scrub. They also occasionally frequent agricultural fields and open outskirts of suburban areas where artificial lights attract nocturnal insects.
• Geographic Range: During the breeding season (spring and summer), they range across the southwestern United States—from southern California, Nevada, Utah, Arizona, New Mexico, and Texas—down through Mexico. They migrate south for the winter, settling in southern Mexico, Central America, and northern South America.

The behavior of the Lesser Nighthawk is uniquely adapted to its crepuscular lifestyle.

• Feeding: Strictly insectivorous, they emerge at dusk to feed on flying insects, including moths, beetles, winged ants, and mosquitoes. They fly low to the ground or just above vegetation in a light, fluttering manner, scooping up prey in their wide, gaping mouths.
• Vocalizations: Unlike the harsh, nasal "peent" of the Common Nighthawk, the Lesser Nighthawk produces a low, rapid, toad-like purring or trilling sound. This soft churring can last for several seconds and is often heard at dusk on their breeding grounds.
• Nesting and Breeding: They do not build a nest. Instead, the female lays two speckled eggs directly on the bare ground, often shaded by a small bush or clump of grass. The parents rely entirely on their pristine camouflage to hide themselves and their offspring from predators.
• Courtship: Males perform low-flying aerial displays, raising their wings and puffing out their white throat patches to attract females, but they do not perform the steep, booming dives characteristic of the Common Nighthawk.
