Swallows

Swallows return every year on time to build nests. poop on my porch an to begin each day with cheeps, chitters and chatters, flying, swooping and typically swallowing through each happy day ending each evening paired up sitting on the electrical wires.  Good night. Babies are fledged who  rarely fall from the nest pasted onto a wood plank. Good grief, cleaning up after them is a chore. Winter peace until another year of evolutionary wonder dawns.
