**Megarare. Possibly the third country record and first locality record. First spotted by Julio Acosta and Guillermo Funes in a distant gull flock on the exposed mudflats near the bocana, then we approached slowly for photos. Identified to subspecies by fairly large size, and some light gray feathering (new) on wing coverts (suggested by Nick Komar). First cycle individual (with some fresher feathers on wing coverts), with distinctly two-toned bill (blacksih tip). Legs greenish-gray. Notably larger than Leucophaeus atricilla and Thalasseus maximus, but not as much so as Larus argentatus. Multiple photos were posted to North American Gulls Facebook group. Initial ID made by OK, and then ID was confirmed from photos by Alvaro Jaramillo and Nick Komar. --O.Komar
