These robins were part of a large flock passing overhead on this warm but dreary day. Were they the harbingers of Spring? It is more likely that they have stayed in the area all Winter.
The Audubon explains that:
“Robins have been known to overwinter in Massachusetts since at least the early 1900s. The number of wintering robins depends largely on the severity of the weather and the abundance of food.
Most birds that regularly winter in New England are well suited to withstand cold temperatures. In the fall, many birds grow additional feathers for insulation. To keep warm while roosting, birds fluff their feathers. Because of the way their feathers are layered, this behavior traps pockets of warm air next to the skin.
During winter days, many birds feed almost continually, storing up fat that they burn off at night to keep warm. There isn’t much one can feed robins in the winter. They’re very adept at finding their preferred food and rarely visit feeding stations. ”
No matter what, I look forward to the day when these perky birds arrive to enjoy my garden for the Summer.
