The hen harrier earned its name from once targeting free-range fowl for their prey. This comes with the downside of being the most intensively persecuted bird of prey in the UK. This is because of the effect the hen harrier has on the grouse population, particularly limiting the number available to shoot. This is especially a problem on the driven grouse moors of Scotland and England.
Female hen harriers and juveniles are brown, with white rumps and long, barred tails. Males are more of a light grey colour.
Whilst in flight, these birds of prey hold their wings in a shallow 'V' shape and glide low whilst searching for prey - this is mainly voles and meadow pipits.
Their diets mainly consist of mammals and small birds.
Europe’s smallest eagle, the booted eagle, otherwise known as the Booted Hawk Eagle, prefers the warmer climes of southern Europe and south central Asia and whilst not threatened globally, its population within Europe is showing signs of decline.
A member of the sub-family of booted eagles due to its feather covered legs and named after the famous Italian ornithologist Franco Andrea Bonelli, the species is considered endangered across Europe but secure elsewhere within its range.
