Bar-headed Goose (Anser indicus) Distribution

They breed in the mountainous regions of central Asia north of the Himalayas ((southeast Russia, northern India and western China). For the winter, most migrate over the Himalayas to Northern India, some to Assam, Northern Burma and the wetlands of Pakistan.

They usually nest near mountain lakes and prefer areas with short grass. During the winter, they favor cultivated grazing areas that provide opportunities to feed on their favorite crops, which are wheat, barley and rice.

These long-distance migrants can fly a 1,000-mile migration route in just one day - as they are able to fly in jet stream; and they are one of the world's highest flying birds, having been recorded at altitudes of up to 10,175 m (33,382 feet).

Bar-headed Geese are popular in captivity and they have been introduced in many areas outside their natural range. For example, escapes are frequently seen in Britain.

These geese are generally peace-loving and generally don't interfere with native birds.

Its wild population appears to be declining due to over-hunting.

Waterfowl, such as ducks, geese, swans and cranes can cause problems around homes.

Bar-headed Geese usually start breeding during the spring-summer of their second year.

They breed in colonies of thousands near mountain lakes. Most nest on the Tibetan plateau. Their ground nests are usually situated in grass or tall weeds.

Most breeding activities are observed in May or June until July.

The typical clutch consists of 3 - 6 (rarely up to 8) white eggs, which are incubated for about 27 - 30 days.



Diet / Feeding:

Bar-headed Geese Bar-headed Geese often feed on agricultural crops during the winter in particular. Their diet includes : grass, wheat, barley and rice. Farmers in many areas consider them as pests.

Geese generally feed on larvae and pupae usually found under rocks, aquatic animals, plant material, seeds, small fish, snails and crabs.

Feeding Ducks and Geese ...

We all enjoy waterfowl and many of us offer them food to encourage them to come over and stay around - and it works! Who doesn't like an easy meal!

However, the foods that we traditionally feed them at local ponds are utterly unsuitable for them and are likely to cause health problems down the road. Also, there may be local laws against feeding this species of bird - so it's best to check on that rather than facing consequences at a later stage.

Please note that feeding ducks and geese makes them dependent on humans for food, which can result in starvation and possibly death when those feedings stop. If you decide to feed them, please limit the quantity to make sure that they maintain their natural ability to forage for food themselves - providing, of course, that natural food sources are available.
