The bluebirds fooled me once this summer. There were three fledglings around my nest box, so I assumed they were hatched in that box. Not true; when I opened the box to clean it, it was completely empty.
There has been a lot of activity around the box the past few days. I'm not assuming anything, but the hope is these younger birds will produce their own batch before the season ends. I have literally hundreds of trailcam images from the past few days, and these are some of the better ones. The sixth and seventh image show that the birds are going inside the box.
If I did this the way I usually do it, my website would be overflowing with trailcam images. Instead I'm using the capability of Blogger to put them all in a slide show. Click on an image to see the larger version, then use the arrow keys to go forward and backward.
