Birds are the only creature to have feathers called plumage,
they are warm blooded and lay eggs. A birds bones are light with
a honeycombed structure for strength. They have good eyesight
and hearing but sense of smell is poor.
In Britain some of the birds we consider common such as the sparrow
are in decline, reasons why are not fully understood. You can
help by putting food and water out for birds - in winter it is
recommended putting out high energy food such as fat, birdcake
seed and nuts. Try to avoid nylon mesh bags as they can trap birds
Spring and Summer feeding is not advisable unless you know what
you are doing, at this time birds require high protein foods such
as mealworms sunflower seeds and currants. Peanuts and bread are
not recommended as they can be harmful if brought to nestlings.
