The BOOTED EAGLE (_Hieraëtos pennata_) is yellowish white upon the brow,
and striped upon the top of the head with a darker shade; the nape is
reddish brown, the mantle and wings blackish brown, each feather having
a light edge, and thus imparting a mottled appearance to the back and
surrounding the wings with two indistinct borders; the shoulder is marked
with a white spot; the upper sides of the tail-feathers are dark brown,
with a light tip, the lower part is pale grey; the feathers on the lower
portions of the bird are light yellow, with brown lines upon the shafts;
these lines are broadest upon the breast, gradually decreasing until they
are scarcely visible upon the hose; in some old birds these dark markings
are only visible upon a small part of the breast; the eyes are of a pale
bronze tint, the beak light blue at its base and tipped with black, the
feet lemon yellow, and the cere straw colour. The young are of a pale
rust red upon the lower part of the body, but in other respects resemble
their parents. The nestlings are brown above, and reddish yellow beneath;
the shafts of the feathers are not striped, and there is no white upon
the shoulder.
