THE SPOTTED EAGLE
Aquila maculata (J. F. Gmelin)
At long intervals stragglers belonging to this species have been taken in these islands, all of them during the last three months of the year.
This species is a summer migrant to Central and Southern Europe, from whence it migrates on the approach of winter to Africa, large numbers passing down the Nile Valley.
The adult is of a warm brown all over, but the young bird has the feathers of the upper parts tipped with buff, and the lower parts striped with ochreous. Length of male 19 in.; the female is slightly larger.
THE GOLDEN EAGLE
Aquila chrysaetus (Linnæus)
This magnificent bird has only been preserved to us as a breeding species owing to the strict protection afforded to the deer in the Highlands and some of the outlying islands off the west coast of Scotland. Thanks to this, it is slightly on the increase in some places, though, as it meets with a speedy death should it trespass over a grouse moor, it can never become generally common. It is a truly grand bird to watch as it soars and circles over the few miles of country to which it claims suzerain rights, and eminently worthy of protection as an object of natural beauty.
The eyrie, which is resorted to year after year, is placed on the ledge of a crag or more rarely in a tree. It is a vast accumulation of sticks, to which additions are made every year, and is lined with tufts of grass. The eggs, usually two in number, are bluish white, marked to a greater or lesser extent with reddish brown.
Its food consists chiefly of mountain hares, though it also takes birds, lambs, and occasionally the fawns of the deer; but although it does sometimes take grouse, they do not form its chief food, and certainly the numbers taken are not sufficient to warrant its destruction.
