This is a regionally significant bird demonstrating breeding behavior, so please be prudent and don't disrupt any breeding birds. Atlas note: It’s May and many of the birds that we now enjoy are on territory and seeking mates. Whether simply seen or heard singing in suitable habitat, your observations are most welcome in the Third Ontario Breeding Bird Atlas: a once in a generation opportunity to provide important data that will help inform conservation policies for years to come.
