After spotting an eastern bluebird outside their cabin located near the Antietam National Battlefield in Sharpsburg, Md, Mark and Jean Raabe built bluebirds boxes on their property hoping to stave off the decline in the bluebird population.  The film shares the story of their success and the current work that continues to grow and fledge bluebirds on Antietam National Battlefield, one of the oldest continually monitored bluebirds trails in the United States and the only trail within a national park.


Inspired by Nature, Art and Crafts by Lori Lewis

Maryland-DC Breeding Bird Atlas 3

The Maryland-DC Breeding Bird Atlas is an effort to understand the populations of birds breeding in Maryland and the District of Columbia. Anyone can help collect data for the atlas—in fact, nearly all atlas data are collected by volunteers. If you already go birding, you are only one step away from atlasing—simply record breeding behavior you observe using a breeding code and submit the data through the MD-DC BBA3 eBird portal. If you’d like to learn more, explore the resources available here and connect with the Atlas on Facebook, Twitter, and Instagram at @mddcbba3.
