Hundreds of Canada Geese often hang out in the Connecticut River, in the waters of the Retreat Meadows and the West River, and in the nearby pasture and cornfield. They did so through most of September, then disappeared. Now they are coming back.
Once in a while among those hundreds of Canada Geese which hang out in the Brattleboro waters, there will be a different goose. Last April there was one.
In mid-April the paired Canada Geese were beginning to nest, while the bachelor and bachelorette geese meandered around the waters and pasture. Among the unpaired geese was a Bar-Headed Goose. Smaller than the Canada Geese, the predominantly light gray Bar-headed Goose stood out among the flock. About two-thirds the size of the familiar geese, it was also stouter. The back of its neck was dark brown, the beak yellow, and the head white. The head was also marked with prominent black bars, hence its name.
Geese do not often get called beautiful. That is not fair, but by our species-centric aesthetic standards, geese just don’t measure up. Not so the Bar-headed Goose. It was a beautiful bird.
Most of the local birding community came around for a look, and some birders passing near Brattleboro stopped for a gander. But generally the response was rather muted, and that requires an explanation.
The Bar-headed Goose is native to Central Asia. It breeds on the high plateau north of the Himalayan peaks, then migrates over those peaks to winter in the Indian subcontinent. And that is the problem. How did the Bar-headed Goose get so far off course?
The answer is that it probably did not get off course. This goose adapts very well to captivity and, I am told, is a favored addition to waterfowl collections, especially in Europe and England. Our Bar-headed Goose had no leg band, but collectors often neglect to band their captive birds.
One inventive birder offered the following itinerary for the Bar-headed Goose in Brattleboro. It was a feral bird in England that hooked up with White-fronted Geese and flew north to Greenland. In Greenland it hooked up with Canada Geese and flew south to Brattleboro, where it was found by local birders in April - when most migrating geese are heading north. I need hardly say that there are more than a few problems with this explanation.
The most likely explanation is that the Bar-headed Goose was an escapee from some private collection or zoo in the United States. The Sibley Guide to Birds includes the Bar-headed Goose among “Exotic Waterfowl,” with this note: “Exotic species frequently escape from zoos and private collections; virtually any of the world’s wafterfowl species can occasionally be seen free-flying in North America.” At best, the rare bird records committee will designate Bar-headed Goose, “Origin Unknown.”
The Bar-headed Goose was around the Retreat waters for several weeks. Then it flew with a flock of Canada Geese to Sunset Lake, and from there to a pond in Wilmington. Then the Bar-headed Goose and the Canada Geese it was with, disappeared. Non breeding Canada Geese often fly north to Canada in the early summer for their molt, and it is a reasonable conclusion that the Bar-headed Goose went with them.
As unusual and distinctive as the Bar-headed Goose is, if it has survived and wanders anywhere in the proximity of North American bird watchers, it will undoubtedly be reported again.
Another rare goose which could show up in the Retreat waters is the Barnacle Goose, a close relative of the Canada Goose. The Barnacle Goose is smaller, pale gray with a black breast, white face and short bill. The white face and white eyebrow make it stand out, even at a distance. In recent years, the Barnacle Goose has been reported during the spring waterfowl migration at the Hinsdale roost just north of the Vernon Dam, and in nearby corn fields. I don’t recall any reports from the Retreat waters, but I would not rule it out.
The Barnacle Goose is European. It winters along the northern coasts of Europe and the United Kingdom, then goes north to breed on rocky coasts of arctic islands. In North America, the Barnacle Goose has been popular in zoos and private collections. The first Barnacle Goose I saw was at the Philadelphia Zoo - and, no, I did not life list it.
Birds escape from zoos and private collections, and for a long time it was assumed that any Barnacle Goose seen in North America was an escapee. There was considerable tension between life-listing birders who wanted another tick, and records committees who dismissed every report of the Barnacle Goose as an escapee, or origin unknown. The life-listers insisted that there were too many regular sightings among the flocks of migrating geese for all of them to be escapees. Their arguments were unpersuasive. The Barnacle Goose is European, insisted various rare bird records committees; it does not come to North America on its own.
Except that the Barnacle Goose does come to North America on its own. The proof came in October, 2005, when a hunter in Ontario shot a Barnacle Goose that has been banded in Scotland in November, 2004. This clearly established this particular goose as a wild bird, not an escapee. It also proved that the Barnacle Goose, like many other European birds, could occasionally make a wrong turn and end up in North America. At that point, records committees became more willing to accept Barnacle Goose sightings.
The Bar-headed Goose and the Barnacle Goose are handsome birds that will stand out in a flock of Canada Geese. The Bar-headed seen in our neighborhood last spring was an exotic escapee. The Barnacle, when it appears, is probably a bird whose GPS went awry. Though respectively “impossibly rare” and “very, very rare,” both are avian messages that encourage us to pause and to look at those abundant geese roosting in our waters.
Good birding!
Note: Photos of Barnacle Goose in the Hinsdale roost were taken by Terry Wright who was the first to find the goose in March, 2007, and post the sighting on the VTBIRD listserve. Terry gave me permission to use the photos then, and I hope his permission extends to the present use. Thank you Terry.
