grey lag goose - Grey Lag Goose
grey lag goose - Head, neck, and upper parts greyish brown; lower breast and abdomen dull white with a few black spots; bluish grey rump and wing-coverts; bill flesh-coloured, with a white nail at the tip; legs and feet flesh-coloured. Length, thirty-five inches.

Eight species of geese are counted among British birds; two of these - the snow-goose (Chen albatus) and the red-breasted goose (Bernicla ruficollis) - may be dismissed at once as rare stragglers to the British Islands. The other six are all winter visitors to our coasts, and are divisible into two natural groups - the grey geese (counting four species), all large birds, brownish grey in colour, and feeders on land; and the black, or dark-coloured geese (two species), very dark in colour, very much smaller in size, and feeders on the tidal flats.

The grey lag is the largest species in the first group, and the only goose that breeds within the limits of the United Kingdom. It was formerly a common summer resident, and bred in the eastern counties of England; it is now confined as a breeding species to a few localities in Scotland and the Hebrides, and in all these last refuges it is said to be rapidly diminishing. That it will diminish still further, until the vanishing-point is reached, hardly admits of a doubt. As a winter migrant from northern Europe it will long continue to visit our coasts, and as a domestic bird we shall have it always with us; for the grey lag is supposed to be the species from which our familiar bird has descended.

The grey lag goose pairs for life, and is gregarious, but is said not to associate with geese of other species. It feeds on grass and young shoots, and in the autumn on grain, and spends nearly the whole day in feeding, and resorts at dark to some open level space to roost, where it is almost impossible to approach within gunshot of the flock, owing to its watchfulness. The grey lag makes a large nest of reeds and grass, lined with moss, and lays six eggs, sometimes a larger number. During incubation the gander keeps guard over his mate, and afterwards assists her in rearing the young. These are led back to the nest every evening by the goose, and sleep under her wing. The male begins to moult a month earlier than the female, and when the time comes he leaves her in sole charge of the young, and withdraws to some hiding-place, or spends the daylight hours on the water, coming to the land in the evening to feed. The goose begins her moult after the young are able to take care of themselves.

The grey lag goose does not range so far north as the allied species; it is only in Norway, where the summer is longest, owing to the influence of the Gulf Stream, that it is found nesting north of the arctic circle.
