Birds nesting on rock ledges are oblong egg.As a rule, the larger the bird, the bigger the eggs she lays, but this rule has exceptions. Eggs are precocial species, the chicks which immediately able to feed yourself, larger in relation to the body of the mother than the altricial species, whose offspring are born helpless. The weight ratio of the egg to the weight of the body in small species are often more than the large ones. The largest egg African ostrich egg is considered. However, when compared to the relative weight compared to the size of the bird, the weight ostrich eggs is 1% by weight of the ostrich. Egg hummingbird is 6% of the weight of the birds.Ostrich EggThe eggs of some birds living in the mountainous areas, have "an edge" (like the edge stiffness). This rib is needed in order not to break the egg, when a bird lands on the socket, which has a small area. It was found that "edge" can withstand a pressure of about 40 kg / cm², while on the side without the ribs to 2 kg / cm².The surface of the egg can be rough or smooth, matt or shiny and almost any color from dark green to purple and pure white. In some species it is covered with speckled, sometimes forming a halo around the blunt end. Color birds' eggs depends on the place and way of breeding. Eggs many secretive nesting birds, as well as many domesticated hen white, and those who lay them on the ground, the color of the shell is often merges with the background of pebbles or plant cloth that lined the nest.
