Merlin

The merlin is a small falcon that hunts birds in fast, low pursuit flights. It breeds across northern regions and winters farther south.

Falcon: A bird of prey in the family Falconidae, adapted for fast flight and hunting with the bill. The merlin is a small member of this broader group of falcons.
Birdwatching: The observation and identification of wild birds in their natural environments. Merlins’ fast flight and distinctive shape make field identification a rewarding challenge.
American kestrel: A small North American falcon that often hunts insects and small vertebrates from a perch or hover. It is a familiar small falcon, but its hovering and perch-hunting contrast with merlin pursuit flights.
Taiga: A biome of northern forests dominated by conifers, lying between tundra and temperate forests. Boreal forest and its edges provide extensive breeding habitat for northern merlins.
Bird flight: Locomotion by birds using aerodynamic forces generated by their wings. Rapid, controlled flight lets merlins pursue prey close to the ground.
Bird ringing: The marking of birds with uniquely numbered bands to study movements, survival, and populations. Ringing records help reveal merlin movements and longevity.
Peregrine falcon: A widespread falcon famous for high-speed dives that strike birds in flight. Both falcons hunt birds, but the peregrine often attacks from above while the merlin chases low.
Tundra: A cold, largely treeless biome with short growing seasons and permafrost or seasonally frozen ground. Some merlins breed near the northern limit of tree growth in open tundra landscapes.
Pursuit predation: A hunting strategy in which a predator actively chases moving prey until capture. Merlins commonly catch birds by chasing them in sustained, low flights.
Satellite tracking: The use of satellite-linked devices to record an animal’s location and movement. Tracking can map long-distance routes between merlin breeding and wintering grounds.
