Western Bluebird Nest from my Bluebird Trail
Oak Titmouse Nest from my Bluebird Trail
These are photos of a Western Bluebird nest and an Oak Titmouse nest from two of my nestboxes on my bluebird trail. When monitoring a birdhouse or nestbox trail it is important to be able to identify the birds and the nests that you find being built in your birdhouses. It is also important to note when eggs are laid and when the hen begins to incubate those eggs.
Even if you only have one or two birdhouses in your yard it is important to monitor them and it’s fun too! You get to see the birds and eggs close up and you help prevent any problems before they occur. Another reason to monitor your birdhouses if you live where there are House Sparrows or European Starlings is to make sure these two species don’t claim one of your birdhouses for themselves (click on the link above to read that post).
My friend Bet has a great website with loads of information on nest and egg identification and monitoring here: Sialis.org
