I received emails recently from Terry Fletcher, who lives on Vance Drive in Bristol, and Ernie Marburg from Abingdon, Virginia. Both emails involved flocks of birds, including American robins and cedar waxwings.

The past two days the robins have been going crazy in my small yard,” Terry wrote. “I live in a woodland area off Vance Drive.”

Terry described a flock of at least 40 robins passing through the relatively small yard. “They were also darting back and forth among the trees,” Terry wrote. “Any thoughts about this flurry of activity?

Ernie Marburg also sent me an email with a query about robins and waxwings.

“I haven’t had much to report recently, but yesterday and today I had large flocks of migrating birds,” Ernie noted. “Yesterday’s flock of cedar waxwings was extremely large.”

Ernie estimated the flock consisted of 400 to 500 individuals. He added that the flock rested for a time in his neighbor’s large oak trees and then went on its way.

“The flock today was less exciting for me, but somewhat even larger than the waxwings,” Ernie noted. The second flock consisted mostly of European starlings with a few American robins in the mix.

Ernie observed the starlings in some neighboring dogwoods as they consumed red berries. His question involved the migration habits of the starlings, waxwings and robins.

The fact is that, although we don’t think of robins very much in winter, they are still very much present in the region. The same is true of waxwings and is particularly true about starlings.

Terry’s wooded area sounds perfect for robins in winter. In the colder months of the year, robins form large, loosely organized flocks, often taking up residence in wooded lots. Ernie’s neighborhood also sounds like a perfect haven for these flocking birds.

The activity observed by Terry is just the way robins behave at time. The activity could have been an example of the birds sensing the approach of a weather front. The robins, reacting to changing conditions, were simply attempting to feed as much as they could before a change in the weather. arrived.

The American robin is a large bird in the thrush family, which in North America also includes such birds as Eastern bluebird, wood thrush, and Townsend’s solitaire.

In the British Isles, the European robin is simply known as “robin” or “robin redbreast.” When the first English colonists arrived in New England and other parts of colonial-era North America, they took pleasure in finding that some of the birdlife in the New World resembled familiar birds from their homeland. The red-breasted American robin looked like the bird they knew in the Old World as “robin,” which motivated them to name the New World bird “robin,” as well.

Other than the red breast, however, the two robins are not all that similar. The American robin is the larger of the two birds. Farther separating these two birds is the fact that the European robin is not a thrush but rather a member of the family of Old World flycatchers.

In some ways, the two robins are similar. Both are fond of earthworms, spending a great deal of their time on the ground foraging for worms. They will also follow human gardeners at their work, waiting patiently for the followed person to disturb the soil with a spade or hoe and expose earthworms for the waiting bird. They are also rather tolerant of humans and have learned to make their own homes close to human dwellings.

Some of the British transplants to North America must have felt homesick for familiar things because several unsuccessful attempts were made to introduce the European robin to the United States and Canada. European robins introduced in New York and Oregon failed to gain a foothold, unlike the introduction of such alien birds as the house sparrow and European starling.

On a few occasions, our American robins have overflown their destinations and ended up in the United Kingdom. For instance, an American robin became a first for London birdwatchers when one was found in that nation’s capital city in March of 2006. Whether of the European or American persuasion, robins have long been a favorite of birdwatchers and nature enthusiasts.
