I must admit, I planted the rubber duck to see how the birds, chipmunks and squirrels would react to it. This is the only good picture taken of a reaction. A chipmunk did go up to the duck and climbed on it, but the camera was not in reach at the time.
Spring is here... the birds are vigorously building nests... this couple were working together building a nest when the male ran into a slight problem; he could not get the string out of another birdhouse to take to his cozy little abode. The bird up on the perch with its "mouth" wide open is his mate. I don't think she is cheering him on. After he gave up, she tried her luck at dislodging the prime piece of string. No luck either.
