Trans-Kentucky Bluebird Trail

This trail will reach from the western tip to the eastern tip of Kentucky. This will be accomplished by counties having registered bluebird trails. These counties will connect with each other, and this will eventually connect the western-most county in Kentucky with the eastern-most county. A county must have at least one trail to qualify as a Trans-Kentucky Bluebird Trail (TKBT) connecting county. To date, 81 trails are part of the TKBT.

A trail consists of at least 5 bluebird nesting boxes in one general area. There is no maximum limit on the number of boxes on a trail.

The following qualifications must be met for a trail to be part of the Trans-Kentucky Bluebird Trail:

  • nesting boxes should be at least 100 yards apart
  • entrance holes of boxes should be at least 4 feet above the ground
  • the bottom of the entrance hole should be at least 6 inches from the outside bottom of the box (to help protect young birds from predators)
  • nesting boxes should be made as waterproof as possible to keep young birds from getting wet and chilled (especially in the early spring)
  • nesting boxes should be cleaned out as soon as young fledge so they will be ready for another nesting attempt. 
  • nesting boxes should not be placed in or near (within 100 yards of) brushy or heavily wooded areas (House Wrens may be found in such areas)
  • nesting boxes should not be placed on trees (because predators can easily climb trees)
  • nesting boxes should not be placed in areas where House Sparrows are found (such as in cities or near feedlots)
  • accurate records must be kept for each box by checking them weekly and recording findings on a trail monitor form to be furnished by KBS. Records are maintained throughout the nesting season (April 1 - August 1).
  • the number of fledglings must be reported to KBS at the end of the season
In addition, you must be a member of the Kentucky Bluebird Society to have your trail certified. The above qualifications will make boxes more attractive to bluebirds and increase their chances of successfully raising young. Boxes on some trails may need some type of predator guards to reduce the risk of predation by snakes, raccoons, and other predators. 

To register your trail, please fill out a Trans-Kentucky Bluebird Trail application form.
