An Egg SVG, or oocyte, or an ovum, or an ovum, is a female sex cell from which a new organism develops as a result of fertilization or through parthenogenesis. The size of the eggs can vary greatly: the mouse egg has a diameter of approximately 0.06 mm, while the diameter of the African ostrich egg can reach 15-18 cm. Eggs are usually spherical or oval in shape, but they are also elongated, for example in insects, hagglings or mules. Oology is a department of zoology dedicated to the study of animal eggs, mainly bird eggs.
Bird Eggs SVG
Females of all kinds of birds lay eggs. Different species of birds lay eggs of different shapes, depending on where they lay their eggs. Birds nesting in holes or holes are rounded. Birds nesting on rock outcrops have oblong eggs.
As a rule, the larger the bird, the larger the eggs it lays, but there are exceptions to this rule. Eggs of brooding species, whose nestlings are immediately able to feed themselves, are larger in relation to the mother’s body than those of nestling species, whose offspring are born helpless. The ratio of egg weight to body weight in small species is often higher than in large species. The largest egg is an African ostrich Egg SVG. However, if we compare the relative weight of the ostrich’s egg with the size of the bird itself, the weight of the ostrich’s egg is 1% of the weight of the ostrich’s egg. The hummingbird egg is 6% of the weight of the bird itself.
Eggs of some birds living in mountainous areas have a “rib” (like a rib of hardness). This rib is necessary in order not to break the eggs when the bird lands on a nest that has a small area. It has been found that the “rib” can withstand pressure of about 40 kg/cm², while on the side without rib it can withstand up to 2 kg/cm².
The surface of the Egg SVG can be rough or smooth, matt or shiny and almost any color from dark purple and green to pure white. In some species it is covered with specks, sometimes forming a corolla around the blunt end. The colour of the bird’s eggs depends on the location and nesting pattern. The eggs of many hidden nesting birds, as well as many domestic hens, are white, and those who lay them on the ground often blend in with the background of the pebbles or plant rags that lined the nest. Birds’ eggs are colored by pigments still in the female genital tract. For example, the pigment biliverdine in chelate with zinc gives the eggs a green or blue color, and protoporphyrin gives the eggs a red, brown color, or spots of such colors.
