[email protected] Abstract—Henslow’s Sparrow (Ammodramus henslowii) is a state-listed threatened species in New York State, and reliable surveys of existing populations are important for successful management. There are many accounts of Henslow’s Sparrows singing at night, casting uncertainty on the efficacy of traditional point-count protocols in assessing this species’ populations.
