Since the 1970's there are 3 billion fewer wild birds in North America.
There are many reasons for the decline in wild birds in North America: loss of habitat, pesticides, feral and house cats, etc. The bright spot is there has been an increase in the Eastern Bluebird since the 1970's when they were concerned to be a species to watch because their numbers were declining.
This result can be directly linked to the work of the North American Bluebird Society and state affiliates, working to create an awareness of the issues and getting people like you to help in this conservation movement: Establishing nestbox trails (Grants available to establish nestbox trails), educating individuals on being good bluebird landlords and teaching the next generation the importance of conservation.
If you're interested in conservation and want to be a part of a group with similar interests please consider joining the Tennessee Bluebird Society.
