The hen harrier is one of the most endangered birds of prey in Britain. Their numbers have fallen incredibly in England in the past, with just ten breeding pairs having been counted last year. While this bird species was once very widespread across Britain, it now seems its domain is limited mainly to Scotland where there are about 630 breeding pairs.
While many would argue that hen harriers can be found throughout the the northern hemisphere of the globe, conservationists in England are worried that this attractive bird may soon be a thing of the past in their country. According to research there are just twelve hen harrier nests in Bowland Fell and only two elsewhere in the country. Thus, Bowland Fell is considered to be something of a sanctuary for the bird in England.
