Right around Thanksgiving, a large group of migrating cedar waxwings, and a few other birds, decided the berries on this tree were ripe and ready. There were plenty of berries to go around but not enough space for all the birds at once. They would take turns visiting the cedar tree for a meal, while the bulk of the flock waited in a nearby oak tree.
These birds are very considerate to each other and have been known to form chains and pass berries along. When the flock is larger than the tree, cooperation is the key!
