Recording time: 743. Elevation (m): 90. Habitat: sandy river bank with single boatman's tent. Confidence in ID: less than 100%. ID determined by: seen poorly in flight in dense fog, but clearly this species on size and shape; not seen vocalizing but sound came from flying group; does not match the few references available to me; could it be a first-winter bird?. Age: likely to be first-winter. Age determined by: voice much higher than adult and with begging quality. Sex: unknown. Group size: several in flock, only one call. Description of behavior: flying over river.
