Griffon Vulture

The Eurasian griffon vulture is a large Old World vulture, 93 to 122cm long with a wingspan of 2.3 to 2.8m. It has a white head, broad wings, short tail feathers, a white neck ruff and a yellow bill. In the nominate race males weigh 6.2 to 10.5kg and females 6.5 to 10.5kg, while the Indian subspecies averages 7.1kg (Wikipedia, general species account).

The rest of the source read is about European populations, such as the Spanish population of about 31,000 breeding pairs, which are not relevant here. It gives nothing on where the species occurs in Bhutan or on its habits there, so none are stated, and its occurrence in Bhutan is flagged for checking.
