This Eastern Phoebe (Sayornis phoebe) was nesting on a porch rafter at the old Freels' cabin, where we have our annual science camp. These birds use mud and mosses as their nesting material. The only problem with having them nest on the porch is their bad hygiene habit of depositing their droppings in a pile below the nest! I can understand why they don't want them in the nest, but they sure do make a mess! The common name comes from the sound of the birds' call, "fee-bee".
