"Few wildlife spectacles equal the sight of thousands of snow geese spread
out to feed across a Texas coastal prairie, resembling giant snowflakes drifted
by the wind. Groups of the large white birds flutter up from the ground on black-tipped
wings and settle back into the vanguard of the advancing front. Other flocks come
streaming in, flying in ragged, interlacing lines and U-shaped formations rather
than the precise Vs employed by the larger Canada geese. The calls of the newcomers
overhead are strangely musical, a high-pitched whouk or kaahk, but
the massed voices on the ground become a constant, ringing clamor." (J.T.)
The snow goose is a medium-sized waterfowl with two distinct color phases--white
and blue. Most snow geese found in Texas are white with black-tipped wings. The
blue goose is bluish gray with a white head, neck and belly, and is found primarily
along the Gulf Coast of Texas and Louisiana. Both phases have pink feet and a
pink bill, marked with a black grinning patch.
Snow
geese breed on the high Arctic tundra and migrate southward after the nesting
season to spend the winter in scattered locations throughout the interior of the
U.S. and Mexico. In Texas they inhabit the Panhandle and eastern half of the state
during the winter months. Here they roost on marshes, playa lakes and coastal
wetlands, foraging on plants, seeds and grains from nearby agricultural fields.
The white and blue snow geese are members of a subspecies sometimes called
the "lesser snow goose." The larger "greater snow goose" breeds around Baffin
Bay and winters only along the mid-Atlantic coast while the "lesser snow goose"
typically nests on the western shore of Hudson Bay. Another white goose --the
Ross' goose--can be found among flocks of snow geese in Texas, although it normally
winters in central California. The Ross' goose resembles the white-phase of the
snow goose but is smaller...about the size of a mallard. It also lacks the black
"grinning patch" on its short, stubby bill. The snow goose and the Ross' goose
are often referred to as "light geese" and are game birds.
Over the past three decades, populations of snow geese have increased dramatically.
The mid-continent snow goose population, estimated at approximately 6 million
birds, now threatens to destroy its Arctic nesting grounds. To learn more about
