Interesting Facts

Himalayan MountainsOne of the most interesting things about the Bar-Headed goose is its ability to fly over the Himalayas on its way to and from its breeding ground. This requires the geese to fly at altitudes of 9,000 – 10,000 meters, making it the highest flying bird (Arkive, 2003-2013).

Some female geese will lay their eggs in other bird’s nests. These "parasitic" birds will lay their eggs in multiple nests, being careful to stay away from nests with females that are incubating. The eggs laid by "parasites" are much less likely to survive than the eggs being incubated by their own mother (Weigmann and Lemprecht, 1991).

Convallaria majalis
Bar-headed geese have a high tolerance for certain poisonous plants such as the Convallaria majalis (Arkive, 2003-2013). When the goslings are younger they have a higher tolerance for these normally considered toxic plants. As the geese age they become more selective in the plants they eat but still have a higher tolerance than most other animals (Englert et al, 1993).

The adult bar headed goose is about 68-78 cm in length with a wingspan of 140-160 cm (Arkive, 2003-2013).

According to the IUCN Red List of Threatened Species, the Anser Indicus is on the list of least concern, but it is decreasing in population (IUNC Red List of Threatened Species, 2013).
