The nesting season is just getting going with the early nesters like bluebirds and chickadees.
I was recently asked a nesting question about chickadees that I thought would be fun to share and shed some light on a not-well-understood scenario with chickadee nesting.
“A Chickadee built a nest in a box in my yard. The nest was finished 8-9 days ago but no eggs yet. I have read that they can build multiple nests, choose the best site, and usually begin laying in about 2 days. Is this nest not likely to be used or should I leave it alone for a while longer?”
Chickadees shop around for nest sites. They check out lots of potential locations. They have been known to begin excavating and even start building a nest in three to five different locations in a season. Usually before the nests are complete they make a final decision on their favorite spot, complete the nest, wait a few days and then begin to lay eggs.
When chickadees excavate homes in rotten wood, the building process can take some time. Carolina Chickadees take about 20 days to lay the first egg after beginning to build a nest site. Black-capped Chickadees will take 7-14 days to lay an egg after beginning to build a nest site.
So, patience is in order before cleaning out a nest box that is thought to be abandoned by chickadees. If the nest looks finished, give it a week to see if eggs show up. If not, they may have chosen another location to raise their brood.
If you are having trouble getting Black-capped Chickadees interested in your nest box, try filling it with wood shavings for them to excavate. They seem to prefer that; whereas, Carolina Chickadees don’t seem to have a preference either way.
