Western Bluebird Nestlings At 5 Days Old all photos by Larry Jordan
House Sparrows, imported from Europe in 1851, multiplied so rapidly in the United States that by the early 1900s they were displacing Bluebirds at an alarming rate by competing for nesting sites. People who loved the very popular bird that "carries the sky on its back and the earth on its breast" were concerned.

In 1934, Thomas Musselman wrote an article for the National Audubon Society urging the establishment of "bluebird trails" across the United States. Over forty years later, Dr. Lawrence Zeleny wrote the book The Bluebird – How You Can Help Its Fight For Survival which prompted letters from bluebird enthusiasts all over North America. From the efforts of these two men and several others, the North American Bluebird Society (NABS) was born in March of 1978.

The Western Bluebird is not out of the woods yet. They are listed as sensitive in Oregon and Utah, and are a candidate for listing in Washington. They are listed as a species of high concern by New Mexico Partners In Flight and considered "in jeopardy" in California. In British Columbia, the Western Bluebird is proposed for designation as a species of "special concern." This is in stark contrast to the Eastern Bluebird which has had a more successful conservation effort over the past 30 years, in large part due to the establishment of bluebird trails.
Monitoring your birdhouses is also a very important part of the puzzle. The entrance hole for bluebirds should never be over 1 9/16" in diameter. This keeps out the European Starling but not the other non-native species, the House Sparrow.
House Sparrow Male
This is the last thing you want to see at your bluebird nest box, a male House Sparrow. I thwarted this intruder by removing the eggs that had been laid in the nest. This tactic has worked for me the only two times I had a House Sparrow problem. To see more about how to combat this threat to the bluebird, visit my friend Bet’s website here. She has the best information on bluebirds on the net.
The North American Bluebird Society is a non-profit education, conservation and research organization that promotes the recovery of bluebirds and other native cavity-nesting bird species in North America. I have had the joy of monitoring three bluebird trails that provide nesting for three other cavity nesting species in my neck of the woods. The Oak Titmouse…
the Tree Swallow…
and the Ash-throated Flycatcher
If you are interested in helping the bluebird’s struggle to survive, join the North American Bluebird Society and if you have the time and habitat, start a bluebird trail. You can help several cavity nesting species in your area by simply putting up birdhouses in your yard and monitoring them.
If you are interested in helping cavity nesting birds in your area or if you have any questions about birdhouses or bluebird trails, please contact me and I will help you get started on this fun and rewarding endeavor.
Thirty top wildlife scientists have announced agreement on some of the highest research priorities to help America’s rapidly growing wind energy industry produce much-needed alternative energy—while also providing safe passage for birds and bats. This coalition of scientists from industry, government, nongovernmental organizations, and universities met recently in Racine, Wisconsin, to address unanswered questions about how continued wind energy development will affect migrating birds and bats. The meeting was hosted by the Cornell Lab of Ornithology, the American Bird Conservancy, and the The Johnson Foundation at Wingspread.
