Which birds fly the fastest?

In terms of cruising speed available for a long flight, swifts are the fastest birds, in terms of flight duration they are the most tireless. For example, a black swift is able to tirelessly rush through the air for several hours at an average speed of about 100 kilometers per hour. It is believed that they can reach speeds of up to 200, and the needle-tailed swift - even up to 300 kilometers per hour. For comparison: in an hour, geese fly 70-90 kilometers, swallows - 60, starlings - 70, cranes - 50, sparrows, finches, buntings - 40 kilometers.

A swift spends 17 hours a day in flight, a city swallow - 15, a barn swallow - 10, a buzzard - 4, an osprey - 2,5 hours, waders, ducks, partridges and most small songbirds that do not use flight to obtain food are in air for a total of no more than one hour a day.

Swifts gave everything to the flight, retaining a minimum of other opportunities for themselves. To be in the air, for example, a swift needs to rush from a high perch, thereby gaining a margin of speed. The swift will not always take off from the ground - the wings are too long and the legs are short.

Swifts can only crawl on a hard surface, but they do it very dexterously thanks to strong paws with strong and sharp claws. They are needed to cling to rocks and climb the walls of deep hollows.

Random interesting fact from the Great Encyclopedia:

Why does a person round his eyes and open his mouth in surprise?

Rounding the eyes in surprise or fear is a reflex action that allows you to expand the field of view and thereby better assess the situation and the degree of danger. A similar reaction is demonstrated by the great apes. Also, in unexpected situations, many animals involuntarily open their mouths, which is associated with the connection to the perception of the vomeronasal organ, which is part of the additional olfactory system. In humans, this organ is not associated with the oral cavity, but the reflex is preserved.

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 ... >>

Potato and electrons 15.09.2005

Japanese scientists from the Institute of Nutrition in Ibaraki propose to treat potato tubers before storage with a low-energy electron beam to guarantee against germination.

Result: Treated potatoes keep at room temperature for four months without sprouting, while untreated potatoes start sprouting after two months. The bombardment of electrons does not change the taste of the potato.
