The Least Poorwill, *Siphonorhis brewsteri*, is a small, cryptically patterned nightjar endemic to the island of Hispaniola. Measuring approximately 19-21 cm (7.5-8.3 inches) in length and weighing around 30-40 grams, its plumage is a masterful blend of mottled browns, grays, buffs, and blacks, allowing it to disappear seamlessly into leaf litter or tree bark. A key field mark for identification is the male's distinct white throat patch, which is less prominent or absent in females. Taxonomic...
This poorwill primarily inhabits dry deciduous forests, thorny scrublands, and pine forests, often associated with limestone outcroppings, from sea level up to approximately 1,500 meters.

Its foraging strategy involves sallying from a low perch or engaging in low, continuous flight to snatch flying i...

Its distribution is highly fragmented, with known populations concentrated in specific dry forest and scrubland areas. In the Dominican Republic, significant strongholds...

- The Least Poorwill is one of the last remaining members of its genus (*Siphonorhis*) in the Greater Antilles, with several close relatives having gone extinct. - It is a master of camouflage, with plumage so perfectly matched to its dry forest habitat that it can be nearly impossible to spot du...
