Bar-headed geese are listed on the IUCN Red List as Least Concerned. They have no special status under the US Migratory Bird Act or on the US Federal List because there is no population living in the US. Nor are they protected under the US Endangered Species Act. CITES contains no special status for the species either.

US Migratory Bird Act: no special status

Justification

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Bar-headed geese (Anser indicus) have a breeding range that stretches from Mongolia south through Russia and Western China to Tibet and as far west as Kyrgyzstan. Approximately 25% of the global population of bar-headed geese winter on the southern Tibetan-Qinghai Plateau. Another wintering area for a portion of the population is India and Bangladesh.

Uses:

斑头雁为我国青藏高原地区较为常见的特产种。青海、西藏的许多地区都曾驯养过大批斑头雁，是一种易于驯养的雁类。由于它的形态优美，而在一般地方又极罕见，因而很早就被各地动物园饲养展出，以供观赏。
