Comments: 23 keer vleugelgeruis van ufo-eenden (snelle vleugelslag) / 23 flocks of unidentified ducks (wing noise). Sunset 18:31, dusk 19:05, dawn 06:43, sunrise 07:17. A nocturnal taping session using a Telinga parabola mounted on a tripod pointing to the sky. The tape was left running and the sounds identified by ear and sonagram the next day. Most recordings are deposited in the archives of The Sound Approach. For species normally flying in flocks (geese, ducks, waders and gulls), it should be noted that an identified call counts for one individual but often indicates the presence of a group (bijvoorbeeld, 11 smienten betekent vermoedelijk dat 11 keer een groep smienten overvloog / ie, eg, 11 wigeons probably means 11 groups of wigeon). Recordings of flying Egyptian Goose (Nijlgans) and Oystercatcher (Scholekster) may relate to nocturnal activity of local breeding birds.
