New study: Bird-like dinosaurs hatched from eggs less efficiently than birds

New research suggests that oviraptor dinosaurs, which looked like birds but couldn't fly, hatched their eggs less efficiently than modern birds. The findings suggest that dinosaurs may have relied on more than just body heat

Tropical rainforest birds are disappearing even in undisturbed forests – researchers fear a new “silent spring”

Long-term monitoring data in Brazil, Panama and Ecuador indicate a sharp decline in birds, especially insectivorous species, and it is possible that the climate crisis and the decline in insect numbers are destabilizing tropical forest ecosystems.

The Great Migration of Small Birds: Who Will Be More Threatening – the Climate Crisis or Humans?

Small migratory birds, weighing no more than a few grams, travel thousands of kilometers each year between their nesting sites in Europe and their breeding grounds in Africa. Dr. Yoav Perlman of the Israel Ornithology Center warns that food shortages, hunting

What about AI and saving eagles from poisoning?

Researchers have developed an innovative algorithm that turns vultures themselves into a smart warning system and prevents mass poisoning events.

Are animals susceptible to optical illusions? What fish and birds can teach us about perception

This led to our research question: Do other animals also “fall for” the same tricks? If a small fish or a chicken is exposed to the illusion, what does this tell us about the way they see and interpret their environment?

High Voltage: How can we reduce bird collisions with power lines?

Israel is a major migratory route for birds, but many of them are injured here by collisions with high-voltage power lines. A new study examines what can be done to reduce the number of these injuries.

Even birds can't escape global warming

A Yale University study examines the movements of 406 migratory bird species and finds that most birds are not moving fast enough to keep up with rising temperatures.

Breakthrough in the study of the evolutionary transition between dinosaurs and modern birds

Among the notable findings: unique feathers known as tertiary feathers, which help close the gap between the wing members and the bird's body, thus enabling flight support - until now, these feathers have not been documented in dinosaurs related to birds.

The divergent adaptation of cuckoos

Cuckoos develop eggs and chicks that resemble those of their hosts, to avoid detection. When they have more than one host, this can lead to the creation of new species of cuckoos – especially if they are “violent”.

Studies from Israel and abroad have found that birds do not chirp only for courtship purposes, and that they have a complex language that affects their choice of who to communicate with and how - even during migration

The crows have become a routine part of our landscape. How smart are they really, and why is one species more successful than another?

The crows know how to count... out loud!

Research shows that crows can intentionally produce up to four vocalizations in response to specific cues, indicating a non-symbolic number system and vocal control similar to that of human infants. This ability offers a foundation

The solar eclipse may confuse the behavior of the birds

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.

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

"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

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

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 ability
