When the Bird Daylight Laser 200 emits a powerful green light that hits bird feathers, it makes a bright splash of light. Which traumatizes them and they can't fly away fast enough. A flock of more than 100 geese immediately took flight..
But as with most aspects of birding, there is a certain etiquette that should be considered. Rule number one: don't point the laser AT the bird. Point it at a tree trunk or large branch closer to you than the bird is, and then describe where the bird is from the light. That way, the bird never even sees the laser.
