My two-hole test box in House Sparrow territory in Woolwine has somewhat of a repeat performance from last year. House parrows had numerous attempts to build a nest and lay eggs–ALL NESTS AND EGGS REMOVED so they could not reproduce in this box! I keep the nests and eggs for educational purposes (displays). After the HOSPs gave up FINALLY (from February through June 2011), bluebirds moved in and were raised successfully. I found partial-HOSP nest materials on June 13. By June 27, bluebirds moved in and finished the nest with their own nesting materials and one egg was laid that morning, the 27th! On July 29th, all bluebirds were fledged. I took a photo of two of the three babies at the age between 13-15 days old–QUICK SNAP and count from 3 babies to 2 babies between July 18 and July 26th. I do NOT know if one died and the parent removed the body (which I doubt because the baby would have been too large by then) or that one baby fledged prematurely. That does not seem
far-fetched considering the number of bird species wanting to use that box and perhaps causing some stress on the parents and the bluebird youngsters in the nestbox…..THEORY on my part as this box is not easy for me to watch on a daily basis. On July 26, here were the babies (photo below). When I returned to the box on July 29, the other two had fledged. HOWEVER, interestingly enough, the female was swooping and “clicking” at me, even when the nest was empty. I saw a couple of sticks on top of the nest, which tells me House Wrens are entering the box.  Perhaps this female wants another brood here and she’s fighting for the box
back, including from me. Wow! Here are the babies on July 26th, 2011. This photo has also been added to my gray tabbed page titled “2-Hole Test Mansion Results” page. Yay for the blues! They are doing all they can to keep territorial rights on this box! This is Year 2 of the test. 1 more year to go and I believe this box will either be sent elsewhere in the U.S. to be tested somewhere else……..OR…….I may continue the test or move it elsewhere in my locale for more testing. Please see the website link of the creator’s page of this test box for more info on this test below:

About 13-15 Days Old....Almost ready to fledge! Photo taken July 26, 2011. CAREFUL and fast photography at this age is a must so as not to spook these little guys!
