Door

A door is a movable structure used to open and close off an entrance, typically consisting of a panel that swings on hinges or that slides or rotates inside of a space.

When open, they admit ventilation and light. The door is used to control the physical atmosphere within a space by enclosing the air drafts, so that interiors may be more effectively heated or cooled. Doors are significant in preventing the spread of fire. They also act as a barrier to noise.

They are also used to screen areas of a building for aesthetics, keeping formal and utility areas separate. Doors also have an aesthetic role in creating an impression of what lies beyond. Doors are often symbolically endowed with ritual purposes, and the guarding or receiving of the keys to a door, or being granted access to a door can have special significance. Similarly, doors and doorways frequently appear in metaphorical or allegorical situations, literature and the arts, often as a portent of change.

Gray-headed Kite

The Gray-headed Kite, Leptodon cayanensis, is a raptor found in open woodland and swamp forests. It shares the genus Leptodon with the extremely rare White-collared Kite. It breeds from eastern Mexico and Trinidad south to Peru, Bolivia,Brazil and northern Argentina.

The nest is made of sticks lined with grass and is built high in a tree. The clutch is one or two white eggs, purplish at one end and spotted brown.

The Gray-headed Kite is 46–53 cm in length and weighs 410-605 g. The adult has a grey head, black upperparts, white underparts, and a black tail with two or three white bars. The bill is blue and the legs grey. The flight is a deliberate flap-flap-glide.

Immature birds have two colour morphs; the light phase is similar to the adult, but has a white head and neck, with a black crown and eyestripe, black bill and yellow legs. The dark phase has a blackish head, neck and upperparts, and dark-streaked buff underparts.

The Gray-headed Kite feeds mainly on reptiles, but also takes frogs and large insects. It usually sits on an open high perch from which it swoops on its prey. The call is a mewling keow.
