Some do, some do not. It depends on where they breed. Peregrine falcons nesting in the Arctic tundra migrate thousands of miles to Central and South America for winter. Those breeding in milder climates - cities, coastal areas, temperate regions - stay year-round.
Which Peregrine Populations Migrate
| Population | Migrates? | Winter range |
|---|---|---|
| Arctic/tundra breeders | Yes - long distance | Central and South America |
| Northern US and Canada | Some migrate, some stay | Southern US, Gulf coast, Mexico |
| Urban peregrines (cities) | No | Stay on territory year-round |
| Coastal breeders | No | Food available year-round |
| Desert Southwest | No | Resident year-round |
Why Some Migrate and Others Do Not
The decision comes down to food. Peregrines that breed in the Arctic lose their prey base in winter - shorebirds, waterfowl, and songbirds all migrate south. The falcons follow their food. Urban peregrines have pigeons and starlings available all year, so they stay put.
Migration Routes and Timing
| Event | Timing |
|---|---|
| Southbound departure | August-October |
| Arrival on wintering grounds | October-November |
| Northbound departure | February-March |
| Arrival on breeding grounds | March-April |
| Key stopover site | Padre Island, Gulf Coast of Texas |
Do Falcons Migrate in Flocks?
No. Falcons migrate solo. They are solitary hunters and solitary travellers. When multiple falcons are seen at the same location during migration, they are taking advantage of the same favourable conditions - not travelling together.

Nesting Preferences
Peregrines nest on cliff ledges, building ledges, bridges, and sometimes in old stick nests of other large birds. They do not build a nest - they scrape a shallow depression in gravel or debris. They are fiercely territorial and will attack any intruder near their nest, including much larger birds like eagles and great horned owls.
Arctic peregrine falcons are among the longest-distance migrants of any raptor, travelling from the tundra to South America and back each year. Urban peregrines never leave their city. Same species, completely different lifestyles.
