The solar eclipse may confuse the behavior of the birds

  • 2 תגובות
Unlike the 2017 eclipse that occurred in August, this eclipse occurs when the spring migration is already underway. And since most birds fly at night, a solar eclipse may affect them significantly
Researchers at the University of Queensland have found that humans can understand the emotional state of chickens from the sounds of their clucking. This ability, which is not affected by previous experience with chickens, has significant implications for improving poultry welfare and can assist in the development of artificial intelligence-based surveillance systems.

Interspecies communication: Humans have cracked the chickens' clucking code

Research led by the University of Queensland has found that humans can tell if chickens are excited or disappointed, simply by the sound of their clucking

Who is braver, the city bird or the country bird?

A new Israeli study examined the siksak, a common species of bird - and found that urban siksaks are braver than their rural brethren. Although we usually all appreciate this beautiful feature, it is possible that the change in behavior in question is actually not so positive for these birds

Buzzards ("Egyptian eagles") born in Israel, disappeared in Yemen - where found thanks to volunteers in Poland and Portugal through watching YouTube

According to Dr. Motty Charter, the fact that two amateur observers are the ones who identified the raccoon, an endangered species, through watching the Charter Group's Birds Online YouTube channel, highlights the enormous importance of citizen science in protecting wildlife.

If birds were visible to the planes

A new Israeli study presents a solution to the many accidents between aircraft and winged creatures, and for the first time succeeds in identifying with the help of radar flocks of large birds, which until now were considered "invisible"

How are the birds coping with the climate crisis?

Researchers have found changes in the body structure of birds, which are probably due to adaptation to global warming

Lessons from birds

"A wise man learns from the experience of others, a fool learns from his own experience." indeed? According to sparrow research, the answer is: it depends

For the first time artificial intelligence for the benefit of the birds

  • No comments
Researchers at Tel Aviv University have developed a system that allows the tracking of hundreds of birds using a tiny GPS device * Thanks to the new system, the researchers were able to encourage the culture of breathing in agricultural areas, thus keeping away birds and various pests that harm the fields

Does artificial feeding of cranes affect them negatively?

Examination of faeces (and movement) of migratory birds, reveals the effect of nutrition on intestinal bacteria. The feeding is of course intended to prevent the birds from raiding the fields

Why do the birds fly?

The researchers mapped the birds' neural network, which controls the coordinated movement of the wings. They found that the evolutionary basis for the development of the coordinated and uniform flapping ability of the wings in birds was created thanks to a natural mutation that developed in a guiding gene, which caused the development of a unique neural network

The reproductive performance of roosters improves according to the changes in the lighting color

It turns out that artificial lighting plays a central role in the reproductive processes of poultry. Prolonged exposure to light in a red wave absorbed through the extraretinal receptors while suppressing the activation of retinal photoreceptors has a positive effect on the reproductive capacity of chickens. The study was published in the journal Poultry Science.

Falcons in the window

In the spring of 2019, the pot in the window of Shlomit ben Meshulam in the Department of Veterinary Resources became a falcon's nest. Shlomit, the secretary of the department, accompanied the chicks until they flew from the nest

Cuckoo without borders

A particularly energetic cuckoo crossed 26 thousand kilometers in the last year and visited 16 countries. Along the way, she became an international network star and provided more important information about the migratory patterns of the world's birds
