The Striated Caracara can solve problems just as much as Cockatoos can, reports the New Scientist magazine in November 2023 about a study at the Messerli Research Institute at the University of Veterinary Medicine Vienna in Austria. The Johnny Rook Project was conducted in collaboration with the Institute of Marine and Coastal Research at the National University of Mar del Plata in Argentina and the Austral Scientific Research Centre in Ushuaia in Argentina. It was funded by the Austrian Science Fund.
Researchers at the Comparative Cognition Unit at the University of Veterinary Medicine (VetMedUni) Vienna, led by cognitive ecologist Katie Harrington, conducted studies on the problem-solving skills of the Striated Caracara in the Falkland Islands.

During the COVID-19 pandemic lockdowns in 2020, humans stayed inside. This period was called the ‘anthropause period.’ This gave researchers an opportunity to study the behaviour of urban (city) birds when humans were not around.
During the anthropause, in cities, there were fewer people, fewer vehicles, less pollution, and less noise. In a study published in the Science journal in September 2020 by researchers in the Department of Ecology and Evolutionary Biology at the University of Tennessee in America, it was found that White-Crowned Sparrows (Zonotrichia leucophrys) changed their songs – with less noise to compete with, their songs became louder.
When lockdown finished, researchers were interested in how birds behaved when humans resumed their usual acitivities.

How do birds know when winter is coming?
Many bird species migrate when winter is coming. They are called migratory birds. They migrate to locations near and far to find food, to find nesting grounds, to return to breeding colonies, to find new places if their habitat is damaged or destroyed, to escape predators, or for other reasons.
The birds that do not migrate are called residential birds. They stay in the same location and prepare themselves for winter.
Birds need to know when winter is coming so that they can start their migration, protect themselves from winter storms, start hoarding food for the coming winter, or fluff-up their feathers to protect themselves from the winter chill.

The Mallard (Anas platyrhynchos) is a medium-sized dabbling duck in the Anatidae family. It is a water bird, living in wetlands.
The male is called a drake, and the female is called a duck. The babies are called ducklings.

What is a smart egg?
The Oregon Zoo and researchers at the San Jose State University of California, in the United States, used a smart egg to learn more about the nesting behaviour of the California Condor. The California Condor (Gymnogyps californianus) is a large accipiter, bird of prey, in the Cathartidae family. Native to North America, it is critically endangered.
Zoologists placed a smart egg – a dummy egg – into the nest of a pair of nesting California Condors during the spring of 2023. It was a single, enormous egg.

Parrots love video chats, say scientists conducting research on parrot intelligence.
Scientists have found that parrots need social connection and mental stimulation. They then wondered whether parrots would welcome video chats to satisfy their need for sociability.
Rebecca Kleinberger, a researcher at the Northeastern University in Boston, America, enrolled 18 parrots and their human owners in an unusual experiment to see if the parrots would connect with their owners and other parrots over video calls.

What do the emu head feathers look like?
The Australian Emu (Dromaius novaehollandiae) is a flightless bird in the Casuariidae family of ratites, and a relative of the Ostrich. It is the second tallest bird in the world, after the Ostrich.
The Emu has soft, shaggy feathers, that are mostly brown or flecked with black. In the red desert of Australia, the feathers have a reddish or red-bown colour. It does not fly, but it can run fast – and it flaps its wings as it runs.

Take a look at the photographs. Are the legs of the Emu and Ostrich crossed?

Why is seabird poop good for the environment?
The poop of seabirds is important for the environment, writes Jason Bittel for the Natural Resources Defense Council (NRDC). Jason Bittel writes that seabird droppings – from Penguins and especially flying seabirds – help to fertilize plants, and whole colonies of seabirds depositing their poop can have a positive affect on coral reefs and climate.

To breathe, birds have lungs and humans have lungs, but birds breathe more efficiently than humans. Why is that?
Bird lungs take up more space in a bird’s body than human lungs in a human body. For example, a human’s lungs compose about 5% of its body, but a bird’s lungs compose about 20% of its body.

Where do most of the birds on Earth live?
Scientists think that there are about 9,500 species of birds in the world.
Birds are classified into 23 orders, such as passerines (song birds), accipters (eagles and hawks, for example), galliformes (game birds), and strigiformes (owls) etc.

What is an alula?
Birds have an alula on each wing.
An alula is a small projection – like a human thumb – on the edge of a bird’s wing. It means ‘winglet’ or small wing.

Humans have unique voices and can tell the difference between one person’s voice and another person’s voice (most of the time). Our friend next door sounds different from our teacher.
The Monk Parakeet is the first bird species known to have multiple vocalisations within its colony of individuals, reports New Scientist magazine in February 2023. Having different individual voices in the parakeet colony means that they can tell the difference between their friends and their enemies.

Scientists found that cockatoos understand when a job requires a toolkit and multiple tools.
Scientists at the University of Veterinary Medicine Vienna, in Austria, studied Goffin’s Cockatoos (Cacatua goffiniana) from Indonesia, reported the New Scientist LIFE magazine in February 2023.
Antonio Osuna-Mascary, a researcher at the University, said that the cockatoos know when to use more than one tool to retrieve food which, previously, scientists thought only chimpanzees could do. This makes the cockatoos only the second non-human animal to use multiple tools to achieve one task.

How do birds manage to stand on cold ground, especially ice, and still keep themselves warm?
Birds in the coldest regions, with ice and snow, still manage to stand for long periods of time on the cold ground.
Birds in arctic and polar regions are adapted physically to extreme temperatures.

What is special about a Woodpecker’s tongue?
The Woodpecker grabs its prey out of holes and crevices in tree trunks. It has a sticky or barbed tongue. When it sticks its tongue in a hole, the tongue acts like glue and insects stick to it. A Woodpecker can eat 1,000 to 2,000 ants a day. It also eats beetle larvae (grubs).
