LRGV Nocturnal Bird Migration Study
Weekly Black-and-white Warbler (BAWW) night flight call activity automatically detected by Nighthawk software operating 8 hours per night (9p-5a CDT, GMT -5) in 2024 and from half-an-hour after sunset to 90 minutes before sunrise in 2025. Nfc activity is the sum of all incidences of a correctly ID'd BAWW detection that occurred at least one minute from another BAWW detection (see Evans & Conway 2021). Data updated weekly.
