Box1 has been given the full treatment. This has involved removing the old nesting material, and in this case the 5 great tit eggs that were deserted last May, and sterilising the inside as much as possible by using boiling water.
No sooner had I done this than we had our first visitor! The bluetit didn't go inside, but it gets us off to a good start!
We are going to try for a bluetit brood in this box again this year. This means making sure that the metal hole plate is bluetit rather than great tit sized. We will see what happens!
