An eagle (from the Latin word,
aquila), is a family of birds of prey in the
order of
Falconiformes.
They live in mountain areas and spend most of their time above the tree line. In Europe, they have become very rare; you'll need to go high up into the mountains to spot any golden eagles.
Eagles are large birds of the type Americans call hawks: broad-winged, with a broad, rounded tail. They hover rather than fly, often in circles, using thermiek whenever possible. The name of 'eagle' is reserved to the larger species, but the smaller buzzards (Buteo), one of the commonest birds of prey in Europe, are very similar. In America, a much bigger continent after all, there is a much larger variety of species.
Also, a song released as a single off ABBA - The Album in 1977. Enjoyed moderate chart success compared to ABBA's other efforts, which went solidly to #1 all over Europe.
The music is very melodramatic, depicting the flight of an eagle with swirling, falling lines from the two singers and the synthesizer.
It brings me to tears just to think of this song. YMMV.
