Northern Red-tails may migrate far to the south, while many at central or southern latitudes especially adults are permanent residents. Most migration is relatively late in fall and early in spring.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too. When hawks and falcons stream across the sky in large numbers, you need a distinct set of birding skills to tell them apart.
Audubon Mid-Atlantic brings together a panel of Brewers for the Delaware River members and city leaders to discuss the importance of watershed health for birds, people, and beer.

Evidence suggests that this threat has declined in recent years. Red-tailed Hawks did not undergo large-scale reproductive failures or population declines during the DDT era earlier this century. Current threats to the species include sporadic shooting and harassment at nest sites, and collisions with automobiles and trucks. Red-tailed Hawks have largely replaced Red-shouldered Hawks throughout much of eastern North America as forest fragmentation has created patchwork habitats favorable to the former.
Overall, the species appears to be increasing its breeding and wintering populations throughout Pennsylvania and much of eastern North America. Red-tails tend to be resident at low latitudes and migratory at higher latitudes, especially in regions of prolonged snow cover. There is little evidence that redtails were substantially affected by the widespread use of organochlorines during the middle of the 20th Century.
In the 20th Century, their range expanded due to increased availability of suitable habitat due to human activities, and reduced human persecution. Redtails favor open areas with patches of trees.
When such areas are either further deforested or are allowed to grow into unbroken forest the number of redtails in the area is likely to decline.
