The largest species can be adapted to flying at high speeds and long distances when it comes to wingspan. The albatross who wanders holds the record with a maximum wingspan of 3.7 meters, but the prehistoric creatures were larger.
Pelagornis Sanders was a bird that lived for 25 million years and was estimated to have a wingspan of 7.4 meters. Similar to albatrosses, it could fly by soaring downhill in the wind or launching from the cliffs. But even P. The pterosaurs dwarfed Sanders – flying reptiles found in the age of the dinosaurs. The biggest one discovered is Quetzalcoatlus northropi, which could have weighed more than 200kg, with a wingspan of 11 meters. This is as large as the Cessna 172 airplane! Computer simulations have revealed the possibility that Q. Northrop could soar at 130km/h and remain in the air for as long as ten days.
The biggest-ever flying animal acted as a gigantic heron.
The largest flying animal in history behaved like a gigantic heron. It plucks prey off the water before launching into the sky.
Quetzalcoatlus northropi was a pterosaur that controlled the sky for millions of years, along with a recently discovered relative.
A few details of the most massive animal to ever take into the air have been revealed. It acts as a heron on the ground and as a condor in the air.
With the area of an airplane Quetzalcoatlus, Northrop was an arachnid that lived in the wetlands of present-day Texas, the USA, over 67 million years ago. Researchers have discovered that the wings’ length of 11 meters required it to leap up to 2.5 meters into the air, then follow by strong flaps that would have pulled it up into the skies.
For the first time, the researchers also identified an even smaller cousin, Quetzalcoatlus lawson. This was likely to have a shorter wingspan, roughly the length of a vehicle. Together, the pterosaurs would have eaten a variety of fish and smaller prey in the water.
The co-editor for a series of recently published papers about the reptiles, Prof. Brian Padian, says, “These ancient flying reptiles are mythical, but the majority of the popular perception of the reptile is artistic and not scientific.
“This is the first comprehensive glimpse of the largest animal to fly in the sense we can tell. The findings are groundbreaking for studying Pterosaurs, the first animal, following insects, to develop flying powered.’
These papers appeared as a “memoir” in the Journal of Vertebrate Paleontology.

Breeding ground
Great bustards are lekking species. At the time of year when they begin the mating season, all males of the area congregate at one place called the lek to fight with females. The females get the opportunity to look at all local males and pick the best to be the father of their babies.
Males first arrive in January, while the females show up in April or March. Before that, males will compete and could even compete to establish their place within the social order. The stakes are very high during the mating season only a quarter of males will attempt to co-marriage, and less than 10% will be successful. In males, only the most dominant ones pass on their genetics.
Male peacocks sport stunningly colored tails; however, great male bustards have to live by using whiskers of white. Thin feathers could be as long as 20 centimeters and have no use apart from a pleasing appearance to females. When they are displayed, males will lift them to display their size.
During mating season, males can also be seen sporting noticeable necks of their males. Instead of the normal simple grey color, males get two-toned patterns that are white on the neck and chestnut brown towards the base. Their necks expand, and two bare streaks of skin appear along their length. As if all that wasn’t enough, males sport glowing white tails, aiming towards the sun to draw females in from some distance.
I’m an old-fashioned bird.
As Juan Alonso of the National Museum of Natural History in Madrid, Spain, and colleagues, whiskers and neck plumage signify high quality. Males with noticeable whiskers and necks are telling females and males that they are tall and old. This makes them both a great mating opportunity and a foe to compete.
Alonso and his group caught the males of 41 from central Spain and followed them for four years with radio tags attached to their backs. They discovered that heavier birds were more likely to have larger whiskers and older animals were prone to more mature neck plumage.
It appears that males’ display is “honest”: males with better displays are in better shape than those who display poorly. The elaborate decorations appear to pay off. Better-developed males display later in the summer, are involved in fewer fights with males, exhibit for longer in the day, and mate more frequently.
