We found hundreds of monarchs in our yard this morning (Sept. 6), and just got interested in the topic. We do have three children, and would like to learn a little science.
Editor's Note: We dated this roost sighting for Sept. 5, the night the roost formed. For consistency, we use the 'first night' date for all roosts even if they are not discovered until the following morning.) We are estimating a minimum of 200 monarchs based on observer’s estimate of “hundreds.”
