Answer
Northern cardinals (Cardinalis cardinalis) face predation from various animals at different stages of their life cycle. Key predators include:
-
Birds of Prey:
- Sharp-shinned Hawks (Accipiter striatus)
- Cooper’s Hawks (Accipiter cooperii)
- Red-tailed Hawks (Buteo jamaicensis)
-
Snakes:
- Rat Snakes (Pantherophis obsoletus)
- Garter Snakes (Thamnophis spp.)

-
Mammals:
- Domestic Cats (Felis catus)

Insects and Arachnids:

The predation pressure varies based on geographic location, habitat, seasonal changes, and the cardinal’s nesting behavior. They often choose dense shrubs and thickets for nesting to reduce the likelihood of predation.
