Mammals:
* Raccoons: These opportunistic feeders are known to raid nests and eat eggs and young.
* Squirrels: Similar to raccoons, squirrels can be a threat to nests, especially tree-dwelling squirrels.
* Opossums: These nocturnal animals are also known to prey on nests and young.
* Cats: Both domestic and feral cats can pose a threat to ovenbirds, particularly young ones.
* Weasels: These small mammals are known to hunt birds, including ovenbirds.
Birds:
* Hawks: Several hawk species, including Cooper's hawks and Sharp-shinned hawks, are known to prey on ovenbirds.
* Owls: Owls, particularly screech owls and barred owls, can also prey on ovenbirds.
* Snakes: Snakes, particularly garter snakes and rat snakes, can climb trees and raid nests, consuming eggs and young.
Other:
* Large insects: While not a primary predator, large insects like beetles can sometimes pose a threat to ovenbird nestlings.
It's important to remember that ovenbirds have evolved strategies to avoid predators, including camouflage, nesting in dense undergrowth, and staying alert for danger. However, they are still vulnerable to these threats, particularly during the nesting season.
