Gallinago gallinago · Icelandic: Hrossagaukur
A cryptically patterned wader famous for an eerie "drumming" sound.
Habitat: Marshes, bogs and wet grassland | Season: Apr–Sep (some overwinter)
Performs a "drumming" display flight at dusk — its outer tail feathers vibrate in the airstream to make an eerie, bleating hum.
Its Icelandic name, Hrossagaukur, means "horse cuckoo" — the drumming sound was once thought to be a whinnying horse spirit.
