A bearded vulture has been seen flying once again over Romania, for the first time in 83 years, according to a statement of the Romanian Ornithological Society.
The bearded vulture (Gypaetus barbatus) is one of the four species of vultures that used to live in Romania.
However, the vulture was last seen on Romanian territory in 1933.
The vulture that is now flying over Romania is named Adonis and is one of the birds that were supposed to contribute to the restoration of the bearded vulture population in France.
The vulture was released in the Massif Central in France in 2014, but didn’t stay there.
The bird left France and flew over several countries such as Denmark, Slovakia, Belarus, Poland, Ukraine, and now Romania.
A satellite transmitter tracks the bird’s route. The bearded vulture is a diurnal bird of prey, characteristic to mountain areas, being typically present at altitudes between 500 and 4,000 meters.
However, it was also found at 7,500 meters altitude, in the Himalayas. It is 105 –125 cm long and weights between 4.5 and 7.8 kg. The female is slightly larger than the male. The wingspan is between 235 and 275 cm.

What do the wolf, the beaver, and the yellow-bellied sapsucker have in common? Each is a keystone species, that is, a species that by its actions may affect a whole community. In many cases, other species greatly depend upon their actions for food, shelter, and habitat.
As a predator, the wolf keeps certain animal populations, like deer, from becoming overabundant and destructive to the surrounding habitat. The beaver creates habitat for songbirds, ducks, and muskrats by building dams.
The yellow-bellied sapsucker provides not only habitat but also food for other species.
This medium-sized woodpecker is what’s known as a primary cavity-nesting bird. It makes—by drilling into a somewhat decayed tree—a cavity where it can build a nest and raise young.
The next year, secondary cavity-nesting birds like swallows, chickadees, and bluebirds can then move in to nest there and raise their own young.
The yellow-bellied sapsucker is also a great provider of food. It drills many “wells” in living trees that bleed throughout the year. The sap attracts insects, and the sapsucker feeds on those as well as the sap itself.
Other small birds like warblers and hummingbirds, as well as butterflies and bats, also come to these sap wells to feed.
Sapsucker wells have been found in over a hundred species of trees, but the sapsucker seems to prefer trees that bleed more than others, such as red maple and birch.

Story Behind the Shot: I visit this park near my home to photograph blackbirds on cold mornings, often aiming to capture the “smoke rings” that form from their breath as they sing out.
On this occasion, I arrived early on a frigid day and heard the cry of the blackbirds all around the boardwalk.
This particular bird was very vociferous, singing long and hard.
I looked to set it against the dark background of the forest, shooting to the east as the sun rose over the trees, backlighting the vapour.
Bird Lore: Red-winged Blackbirds are some of the most abundant and conspicuous birds in North America.
Beginning in early spring, males perch above marshes, pond edges, damp fields, and roadside ditches, flaring their red shoulder patches and belting out arresting songs to announce their claims to breeding territories.
This peculiar device, in the collection of the Science Museum in South Kensington, London, looks like a tiny gas chamber a movie villain would use.
Throw in your enemy—in this case, a small innocent canary—close the hatch, turn open the valve to let in poisonous gas from the cylinder above, and then laugh manically as the bird suffocates and dies.
In reality, it’s the opposite. This device is used not to kill canaries, but to revive them. The cylinder attached to the top of the metal box contains life giving oxygen.
They are known as Canary Resuscitators. Coal miners used to go down to work carrying canaries with them in glass chambers such as these.
Underground mines can contain potentially deadly gases such as carbon monoxide that can form during an accident such as fire or an explosion.
The colorless gas is equally deadly to both humans and canaries alike, but canaries are much more susceptible to the gas, and react more quickly and visibly than humans do, thus alerting miners to the presence of the poisonous gas.
When a disaster strikes inside a mine, rescue workers would descend into the mine carrying a canary in a Resuscitator.
The glass and metal box has a circular open door in the front to let air in, but a grill prevents the canary from escaping.
If there is carbon monoxide in the air, the canary would show signs of distress. It would start swaying noticeably on its perch and eventually fall of it.
If the canary loses consciousness, the door to the box would be closed and the valve opened, allowing oxygen from the tank on top to be released and revive the canary.
