_{Maynard Sumner checking a nest box.}

Here you can download the latest MBS Nesting Data form to compile your nest box results for the entire season. Then, you should submit it to MBS to be compiled with other data from across the state. Also, there is nesting season results for two recent years to compare what you may be seeing in your yard. (But don't be concerned if your results are a lot different. No two seasons in Michigan are the same!). Finally, there are some tips for you to monitor your nest boxes more efficiently and safely for the birds.
