Study casts doubt on traditional view of pterosaur flight

This is an image of a reliable reconstruction. Soft tissues like ligaments play a big role in determining a joint's range of motion. But soft tissues rarely fossilize, causing problems for paleontologists trying to reconstruct who extinct creatures may have lived. Now researchers have shown a new method for inferring the extent to which ligaments inhibit joint movement, which could be helpful in reconstructing ancient species.

Quaillike creatures were the only birds to survive the dinosaur-killing asteroid impact

When the dinosaurs died, so did forests -- and tree-dwelling birds

Paper: Early Evolution of Modern Birds Structured by Global Forest Collapse at the End-Cretaceous Mass Extinction

https://www.cell.com/current-biology/fulltext/S0960-9822(18)30534-7


Avialan Diversity at the End-Cretaceous

At least four major clades of near-crown stem neornithines persisted into the latest Maastrichtian [4], including Enantiornithes, the most widespread and diverse clade of Mesozoic Avialae. The figure follows stratigraphic ranges from [4], with topology following recent work (e.g., [21, 22]).

Scientists can predict which storks will migrate to Africa in autumn and which will remain in Europe

https://www.sciencedaily.com/releases/2018/05/180524141655.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


A few week-old young storks in their nest, which were equipped with transmitters. The transmitters, weighing less than 60 grams, record the GPS coordinates and the acceleration of the birds. The latter piece of information tells the researchers whether an animal is flapping its wings or whether it is gliding.

Water samples were collected and analyzed for markers indicating the source of bacteria to beaches, and gulls were a significant source.
