Number: 300

This is the second year in a row we have had the migration in our back yard. Either I missed their first day with us, or there were many fewer this year. Last year, they arrived more than a week earlier. This photo shows only a portion of the butterflies. They stop in several trees in the yard, not just this one. The 300 number is a small estimate. There are more than we can count.
