It’s time to clean out your bluebird box if you haven’t already! Bird Protection Law permits the cleaning out of nests between 1 September and 31 January. I haven’t already… So today I did. I didn’t last year, I forgot. So there are probably two maybe three nests in this box on top of each other. I thought it would be interesting to document what they were made of. So here goes.
The little cup was toward the back corner of the box. The first thing I see is Cedarbark The layers are pretty definite, it looks like moss and horse manure at the bottom.
On top of that maybe some fluff from grass seeds, horse hair and then on top of that grass stems.
The red in the final layer is I believe shredded cedar bark.
