Which bird lays the largest eggs?

Usually, the larger the bird, the larger the egg it lays, but the size of the eggs is not always related to the size of its "parents". The size of the egg depends on the amount of food needed to feed the growing embryo until it hatches from the egg.

Birds that are able to take care of themselves almost immediately after hatching from the egg develop into large eggs, which store a large enough amount of nutritious yolk so that the chick hatches already sufficiently developed. The chicks that hatch blind and helpless are born from small eggs in which the supply of food is insufficient for their full development.

Not all bird eggs are similar in shape to chicken ones: some birds lay oblong, round and even pear-shaped eggs. Eggs laid in high places are usually shaped to prevent them from rolling as much as possible. As for the size of the eggs, the champion here is the ostrich. An ostrich egg can reach 15-17 cm in length and 13-15 cm in diameter, occupying the same volume as 12-18 chicken eggs! But ostrich eggs are the largest among the eggs that are laid by living birds.

In ancient times, there were birds, next to whose eggs, ostrich eggs would have seemed tiny. We are talking about the prehistoric legendary Roc bird, which was found in Madagascar. The egg shell of this bird, found by scientists, gives an idea of the size of the eggs themselves. They reached 33 cm in length and 23-26 cm in diameter. The volume of such an egg was equal to 8 liters, which is 6 times more than that of an ostrich egg and 150 times more than that of a chicken!

And the smallest testicles are hummingbirds. Some varieties of hummingbirds lay eggs as short as 6 mm long.

Random interesting fact from the Great Encyclopedia:

Why did the Turks and Caicos Islands have igloos on their coat of arms?

The old coat of arms and flag of the Turks and Caicos Islands, which are part of the United Kingdom, showed a sailboat, a local resident on the shore and two piles of salt, which reflected the role of the colony as a major salt mining point. However, the English designer, having received the images, confused the mounds of salt with buildings and added black "doors" to them. Thus, the national dwellings of the Eskimos - the igloo appeared on the coat of arms of the tropical islands, which was in use until 1968.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
