For more years than I care to remember, I have vainly tried to entice purple martins to nest in my yard. Each year during the late winter or early spring, a handful of purple martins magically appear at my martin house.
When these early migrants show up, my hopes run high that this will be the year I will become a purple martin landlord. My high expectations are dashed in a few days when the birds disappear, never to return.
