LRGV Nocturnal Bird Migration Study
Weekly Canada Warbler night flight call (nfc) activity at the Alamo Inn automatically detected by Nighthawk software. There is no 2026 data for the week of Sep 12-18. Nfc activity is the sum of all incidences of a correctly ID'd CAWA detection that occurred at least one minute from another CAWA detection (see Evans & Conway 2021).
