The Brant is analogous in look to the Canada Goose, however smaller and darker. The adult has a grey stomach and breast, white rump, and black neck and head with a skinny white necklace and no chin-strap.
No different geese nest as far north because the Brant, and few migrate as far. These small geese are attributes of coastal areas in the summer season and winter; most birdwatchers know them from seeing their wintering flocks alongside each of our coasts.
Traveling between their summer season and winter outposts, they might fly at altitudes of a number of thousand feet as they cross great expanses of land or open ocean.
The Brant Goose could also be thought of as a salt-water bird, for it by no means ascends our rivers past the effect of the tides, neither is discovered on inland lakes or ponds, except or not it’s wounded, and occur to alight by chance in such locations.
To this natural predilection for salt-water could also be attributed its behavior of flying round the projections of capes and headlands: it very seldom passing immediately over a neck of land, except abruptly stunned and alarmed by the gunner.
Brant Goose Description
In North America, two subspecies of brant are acknowledged, principally on account of variations in plumage traits.
Atlantic or Pacific (black) brant are separated into subpopulations inhabiting distinct ranges and having a genetic variation.
Brant are small, darkish geese that have giant wings, which give them their attribute robust flight.
The compact, somewhat short-necked Brant is a beautiful small goose with a blackhead, white necklace, and wealthy brown body brightening to white below the tail. They winter in flocks in bays, estuaries, and lagoons, the place they eat eelgrass and different aquatic vegetation.
They nest within the Arctic in wetlands thick with grasses and sedges. Flocks give pleasing calls harking back to Sandhill Cranes, and the sounds carry for long distances.
In the latest a long time, some Brant have begun to make use of upland fields, grazing on the grass a lot as Canada Geese do.
Brant has quick necks, small heads, and bills. All subspecies have a blackhead, bill, breast, primaries, tail, and legs. The in any other case black neck has a sequence of white striations, referred to as a necklace, close to the center.
The shade of the stomach varies in accordance with subspecies and subpopulation. Both sexes are identical in plumage, besides that the male’s white necklace is bigger than the feminine’s.
Brant spends a lot of the year in flocks. They forage by grazing or by swimming into shallow water and tipping ahead to achieve aquatic vegetation. Flocks kind of tight swarm-like groupings, much less linear than skeins of Canada Geese.
They give distinctive, grating calls which are usually the first clue to their presence. On breeding grounds, they nest on the ground in small colonies close to water.
There are presently two populations of brant acknowledged in North America: Pacific and Atlantic.
The Pacific (or black) brant have exhibited a major downward pattern from 1964 to 1992 and look like under historic inhabitants ranges.
Brant is strongly dependent upon sure meals and thus the inhabitants are weak to losses on account of hunger and temporary breeding failure.
Salt bays, estuaries; tundra (summer season). Usually on most coastal tundra of high Arctic in the summer season, alongside coastlines in pretty gentle climates in winter. Migrants could make regular stopovers on just a few freshwater lakes within the inside of the continent.
Brant Goose Breeding
Brant usually nest in free colonies in Arctic North America and Russia. They breed on the coastal tundra, on low and barren terrain; on islands, deltas, lakes, and sandy areas amongst puddles and shallows, and in vegetated uplands.
To keep away from predation, brant usually constructs nests on small offshore islands, on islands in small ponds, or on gravel spits. Parents are bonded for all times and each is inclined to nests and younger. Female brant lay an average of 5 eggs.
A compact, small goose with a stubby bill and a comparatively quick neck in comparison with most geese.
Brant Goose Color
Adults have a blackhead, neck, and breast with variable white neck markings.
They have brown wings, white undertail, and pale flanks and stomachs that may range from pale brown (in eastern North America) to blackish (within the West).
Juveniles have pale fringes on the wing coverts and little or no white on the neck.
Principally plant materials. In migration and winter, eats aquatic crops; eelgrass closely favored the place out there, additionally takes wigeon grass, rock grass, green algae, others. On breeding grounds, grazes on sedges, grasses, pondweed, others. Also eat just a few aquatic bugs, mollusks, worms.
Forages by wading or tipping up in shallow water, or by strolling on tidal flats or onshore. Feeds in flocks at most instances of the year.
Brant Goose Eggs
3-5, hardly ever as much as 8. Creamy white to pale olive, changing into nest-stained. Incubation is by feminine solely, 22-26 days, often 24. When feminine leaves nest to feed, she covers eggs with down, maintaining the heat.
Young: depart nest inside 1-2 days after hatching, are tended by each parent and led to feeding areas, the place younger discover their very own meals. In long daylight of high Arctic, younger feed in any respect hours and develop quickly, fledging at 40-50 days.

Pair bonds often shaped on wintering grounds. Often breeds in free colonies.
Nest site is on a small island in a tundra pond, the slight rise in low grassy flats, often inside 1-5 miles of coast and infrequently subject to destruction by storm tides.
The nest is a shallow bowl of grass and different supplies, closely lined with down.
Brant Goose Migrating
In North America, brant winter alongside the Pacific coast from Alaska to Baja California and mainland Mexico, and alongside the Atlantic coast from Massachusetts to North Carolina (primarily from New Jersey to North Carolina).
Since the mid-1960s, more than 80 p.c of the counted winter inhabitants from Russia, Japan, and North America have occurred in Baja California and different elements of northwest Mexico.
Brant winter primarily in marine habitats which are marshy, alongside lagoons and estuaries, and on shallow bays. Habitat use is commonly restricted by the provision of eelgrass, a staple of the brant diet.
Brant Goose Facts
The extreme winter of 1976–1977 in eastern North America froze Atlantic Brant out of their conventional marsh and lagoon habitats for a number of months.
Some Brant compensated by shifting inland from estuaries onto farm fields, lawns, and golf programs, to feed on grasses not usually a part of their diet. This behavior remains to be seen some 40 years later, as eastern Brant nonetheless forage inland from New York to Virginia.
All adult Brant have white markings on the neck, most pronounced within the “Black” Brant and least developed within the “Atlantic” Brant, although people present variation within the size of this necklace in all populations. A Canadian study discovered that people tended to pair with others that had comparable quantities of white within the necklace.
Brant additionally happens in western Europe, the place they’re usually referred to as Brent Geese.
The oldest recorded Brant was feminine and was over 27 years, 6 months old. It had been banned in Alaska and was present in Washington.
Where to search out Brant Goose
Look for Brant in winter in saltmarsh lagoon techniques, bays, and sounds. They feed most closely at decrease and falling tides when eelgrass beds are inside attaining.
In some locations, Brant has change into regular visitors to golf programs and parks the place looking isn’t permitted. In such locations they might tolerate pretty shut method; in any other case, they’re fairly skittish. Bring or borrow a recognizing scope to get one of the best views of their lovely plumages.
In the 1930s, a sudden die-off of eelgrass alongside the Atlantic Coast (the primary winter meals of Brant) could have had a serious impression on this species.
No long-term harm to numbers, as Brant had been in a position to change to different meal sources, and eelgrass has made partial restoration in these areas.
