Since the program was revived in , nearly one million records have been transcribed. This historic collection of migration cards illuminates almost a century of migration patterns and population status of birds. The Future: Scientific research using BPP data is working to assess changes in bird migration at broad spatial and temporal scales in response to climate and land-use changes. The program aims to continue working with online volunteers to unlock this data and make it available for additional research studies.

Attach the entrance guard on a bias for a visually appealing diamond shape. Mount the finished bluebird nesting box between 5' to 10' above the ground. The bluebird house should face out towards an open field or grassy area. One of the most critical elements of a bluebird nest box is the size of the entrance hole.
If the hole is too small, bluebirds cannot enter the nest box. If the size of the hole is too large, bluebirds might be forced out by the larger, more aggressive sparrows and starlings. For over 35 years, the National Wildlife Federation NWF has encouraged homeowners, schools, corporations and municipalities to incorporate the needs of the local wildlife into their landscape design.
So far, the NWF has recognized the efforts of nearly , individuals and organizations who plant native shrubs and plants for food, cover and places for raising their young, provide include a source of drinking water, and add nesting boxes for cavity nesting birds.
For more information on how you can attract more wildlife, and to certify your yard and gardens, please visit: National Wildlife Federation: Certify Your Wildlife Garden. Answer: Bluebirds can be very selective when looking for a place to raise their young, and location is an important consideration. We have been successful in attracting bluebirds to birdhouses that face open areas of our yard and are attached securely to posts and trees between 6' to 8' feet above the ground.
We do not have the tiny blue birds here but we do have the beautiful and rather screechy noisy blue jays who absolutely love the cherries on our cherry tree. My hubby gets a little hot under the collar at them every now and then but I really don't mind sharing our garden's bounty. We never pick the top of the tree anyway. Its interesting that you had a family of flying squirrels move in when you moved a bluebird house deeper into the woods, they are cute little fellows but not what you were trying to attract.
I also found it interesting that you had a variety of bluebird house styles and they chose the slant front style here last year, it will be fun to find out what they choose this year. Appreciated these plans for a bluebird nesting box. I have at least two pairs of Mountain bluebirds each season.
Peterson often credited his direction in life to a teacher who took her students outside regularly and nurtured his interest in birds after seeing his drawing of a blue jay. For more information about the Peterson program contact Norina.

While the photographs are quite small, pinch zoom will allow you to make them bigger.

It comes with an index where you can select a bird, and then the app sends you to its page. If you want to make things quicker, you can also use the search engine.
Once you find the bird you were looking for, you can view illustrations of the bird and maps of the areas it populates. The app contains illustrations instead of pictures, which provides a lot more details on the anatomy of the bird. This is the best birding app for both regular and experienced birders, as it provides both basic and advanced technology.
Also, this is the best app to identify birds or to let you document your own sightings. This way, you can create new entries in the database.
