When we talk about Purple Martins, there is a well known fact associated with them. It is a fact that these little birds do not share their martin houses with other birds. The common reason behind this habit is the fear of being killed by birds such as starlings and sparrows. However, these are not the only threatening species. There are other species as well who may cause harm to the martins, preventing them from ever nesting in your birdhouse again. Here are some predators of the purple martins that you should be aware of:
Woodpeckers
As the name suggests, woodpeckers are fond of wood and can ruin the wooden bird house by pecking into the already made holes thereby enlarging them. These birds are not a major threat to the martins; however, having them in your garden would mean the destruction of the martin house. In order to prevent the destruction, it is advised that a 1/16'' thick piece of aluminum should be sandwiched between two pieces of wood which will not let the woodpecker succeed in his mission of enlarging the entrance holes.
Snakes or Squirrels
Animals like snakes and squirrels are classified as climbing predators for the purple martins. These species, in addition to raccoons, love birds and their eggs. Squirrels are quick to grab the egg and one attack by any of these animals may result in the complete destruction of a colony. Moreover, since raccoons are strong, they also possess the ability to tear the aluminum used in the martin house apart in order to get to its prey.
Snakes are also highly dangerous for purple martins. Not only do they climb the bird house pole, but also live in there until every single member of the colony is consumed. If given a chance, a snake can easily clear your martin house before you even realize it.
Owls and Crows
Owls, crows, blue jays, hawks, and coopers are all put into the same category that is commonly termed as the flying predators. Interested in both the adult birds and the eggs, these smart birds will destroy your martin house with great speed. Usually, the adult birds escape and do not return ever again. Since these flying predators are a common sight for the purple martins, the adult birds know how to out maneuver them.
In order to avoid getting your colony of purple martins destroyed by these predators, it is advised that the martin house should be properly placed away from trees and should have a good amount of aerial space around it.
