Slender, pointed beakSlender, pointed beak

Thin, slender, pointed beaks are found mainly in insect eaters. They are used to pick insects off leaves, twigs, and bark. This warbler is a good example.

Chisel shaped tipChisel shaped tip

Woodpeckers have strong beaks which taper to the tip, forming a chisel for pecking holes in trees for food or nests. Most feed on insects which live under the bark.

Hawks, owls, and other birds of prey which catch and kill live prey have sharp, "hooked" beaks. These are used to bite the skull or neck and also to tear the body into pieces small enough to swallow.

Flat and wide at baseFlat and wide at base Beaks which are flat and wide at the base

are found in birds which catch insects in flight, such as flycatchers. These birds also often have whiskers at the corners of the mouth, which effectively widens the mouth opening, allowing more effective capture of prey.

Independent, flexible toes for graspingIndependent, flexible toes for grasping

SONG BIRDS or PERCHING BIRDS (warblers, thrushes, wrens, etc.) have independent, flexible toes, with one pointing backwards, ideal for grasping perches. They don’t fall when they sleep because a tendon on the backside of the ankle automatically flexes locking their toes around the branch. With feet locked, sleeping birds don't fall. As the bird stands up its feet release.

WOODPECKERS have two toes pointing forwards and two backwards; for climbing up, down, and sideways on tree trunks.

Webbed for swimmingWebbed for swimming

WATER BIRDS such as ducks have webbing between their toes for swimming. GULLS also have feet similar to these so they don't sink while walking in the soft sand or mud near the water's edge.

FeathersFeathers

Feathers are one of the most prominent features of a bird's anatomy and they are unique to birds. Feathers perform a number of functions for a bird:

1) They provide insulation, body temperature of most birds is maintained at around 40 C;

2) Feathers allow for flight;

3) Feathers control what a bird looks like by supplying the bird with colors. Colors in birds are used for camouflage and attracting a mate(consider the tail feathers of a peacock).

Feather StructureFeather Structure Feathers have a basic form

of a hollow, central shaft called a rachis and a number of smaller side branches. The side branches are called barbs and are linked together by a set of barbules and their "hooklets" sometimes called 'Hamuli' (this is perhaps best understood by seeing the diagram). The base of the feather - where there are no side branches - is called the quill.

Contour FeathersContour Feathers

Contour feathers give the bird its characteristic smooth round shape. They also give the bird its visual coloring and provide a first level of defense against physical objects, sunlight, wind and rain. They are very important.

Down feathersDown feathers

Down feathers are smaller and lack the barbules and their accompanying hooklets so they are not zipped together and do not look as neat. In fact they are soft and fluffy. They provide most of the insulation and are so good at this that mankind for many years collected down feathers from various birds to put into sleeping bags and jackets to help keep us warm.

SemiplumesSemiplumes

Semiplumes are half-way between a contour feather and a down feather. These occur between the contour feathers and help to supply insulation and a certain amount of form as well.

FiloplumesFiloplumes

Filoplumes are very small and have only a very few barbs at their tips. They are believed to have a sensory function, helping birds keep their feathers in order.
