About the Cuckoos
The cuckoos are a family, Cuculidae, of near passerine birds.
The order Cuculiformes, in addition to the cuckoos, also
includes theturacos (family Musophagidae, sometimes
treated as a separate order, Musophagiformes). Some
zoologists and taxonomists have also included the
unique Hoatzin in the Cuculiformes, but its taxonomy
remains in dispute. The cuckoo family, in addition to those
species named as such, also includes
the roadrunners, koels, malkohas, couas, coucals and anis.
The coucals and anis are sometimes separated as distinct
families, the Centropodidae and Crotophagidae respectively.
The cuckoos are generally medium sized slender birds. The
majority are arboreal, with a sizeable minority that
are terrestrial. The family has a cosmopolitan distribution,
with the majority of species being tropical. The temperate
species are migratory. The cuckoos feed on insects, insect
larvae and a variety of other animals, as well as fruit. Many
species are brood parasites, laying their eggs in the nests of
other species, but the majority of species raise their own

About the Eagles
Eagles are members of the bird family Accipitridae, and belong to
several genera which are not necessarily closely related to each other. Most of
the more than 61 species occur in Eurasia and Africa. Outside this area, just
two species (the Bald and Golden Eagles) can be found in the United States
and Canada, nine more in Central and South America, and three in Australia.
Many different species of eagle are found in the Philippines. Eagles differ
from many other birds of prey mainly by their larger size, more powerful
build, and heavier head and beak. Even the smallest eagles, like the Booted
Eagle (which is comparable in size to a Common Buzzard or Red-tailed
Hawk), have relatively longer and more evenly broad wings, and more direct,
faster flight. (Despite reduced size in aerodynamic feathers) Most eagles are
larger than any other raptors apart from some vultures. Species named as
eagles range in size from the South Nicobar Serpent Eagle, at 500 g (1.1 lb)
and 40 cm (16 in), to the 6.7 kg (14.7 lbs) Steller's Sea Eagle and the 100 cm
(39 in) Philippin Eagle.

About the Owls
Owls are a group of birds that belong to the order Strigiformes, constituting
200 extant bird of prey species. Most are solitary and nocturnal, with some
exceptions (e.g. the Northern Hawk Owl). Owls hunt mostly
small mammals, insects, and other birds, although a few species specialize in
hunting fish. They are found in all regions of the Earth except Antarctica,
most of Greenland and some remote islands. Though owls are typically
solitary, the literary collective noun for a group of owls is a parliament. Living
owls are divided into two families: the typical owls, Strigidae; and the barnowls, Tytonidae. Owls have large forward-facing eyes and ear-holes; a hawklike beak; a flat face; and usually a conspicuous circle of feathers, a facial disc,
around each eye. The feathers making up this disc can be adjusted in order to
sharply focus sounds that come from varying distances onto the owls'
asymmetrically placed ear cavities. Most birds of prey sport eyes on the sides
of their heads, but the stereoscopic nature of the owl's forward-facing eyes
permits the greater sense of depth perception necessary for low-light hunting.

About the Bats
Bats are mammals of the order Chiroptera (pronounced from
the Greek cheir (χείρ) "hand" and pteron (πτερόν) "wing") whose forelimbs
form webbed wings, making them the only mammals naturally capable of
true and sustained flight. By contrast, other mammals said to fly, such
as flying squirrels, glidin possums, and colugos, glide rather than fly, and can
only glide for a short distance. Bats do not flap their entire forelimbs,
as birds do, but instead flap their spread-out digits, which are very long and
covered with a thin membrane or patagium.
Bats represent about twenty percent of all classified mammal species
worldwide, with about 1,240 bat species divided into two suborders: the less
specialized and largely fruit-eating megachiroptera, or flying foxes, and the more
highly specialized and echolocatingmicrochiroptera. About seventy percent of
bats are insectivores. Most of the rest are frugivores, or fruit eaters.
