Birds   🐣

Birds are oviparous animals, they are mostly herbivores but not all of them are herbivores . Their body is covered  of feathers, to keep them  warm. Although birds have wings, not all birds can fly, for example the flemish and the penguin cannot fly . There  are 10,000  species in the world !
                 
                                             
What do the birds eat.
  
The herbivores birds eat plants and seeds. But carnivores birds eat worms and little insects...

Where do the birds put their nest

Many birds place their nests in trees and shrubs, birds can use  human objects por example:
chimneys, holes in roofs, etc...

How do birds reproduce

Birds reproduce by mating and then depositing eggs which they incubate and hatch. When chicks are born, their parents feed them and raise them until they can learn how to fly.

How birds fly and about migrations

Birds can fly thanks to their wings but also to their weight, to the aerodynamics of the lift, drag and thrust.

Birds migrations are very interesting to study. They are the regular seasonal movement, often north and south along, depending what season of the year.
