Springtime Over Construction

Here in the Sierra Mountains, it is springtime. All the bugs and animals are in hyper mode. So many birds that are not visible during the winter months have come home to build their nests.
The nest in this picture is so overbuilt that the birds have no room to fit in the nest to lay their eggs. A portion of this nest was constructed of nylon fishing line. I can just picture these birds so excited to build their cozy spot that they neglected to take note of the space available for the nest.
