L124 Whistle was born to L77 (Matia), her third calf, January, 2019. Whistle, a male, has a large family group to look after him.
L124 “Whistle” was named for the whistling vocalizations the Southern Residents use. Whether there is a special purpose for the whistling sounds is not known. However, whistles are used during social interactions and in short-range communication.
Whistle was first seen during a livestream of TV stations in Seattle. They aired live aerial footage of several groups of killer whales in Puget Sound and viewers were able to see a very small calf among them. During this livestream it became clear that the calf’s mother was L77 “Matia” (b. 1987)!
