Archaeologists found ancient bird footprints that are 60 million years too early. ... the evolutionary transition from dinosaur to bird and the timing of the birds’ origin are still contested ...
A phylogenetic tree unequivocally indicates that modern hummingbirds originated in South America, with the last common ancestor of all living hummingbirds living around 22 million years ago. [9] A map of the hummingbird family tree – reconstructed from analysis of 284 species – shows rapid diversification from 22 million years ago. [43]
Here's a riddle: how did an order of flightless birds manage to spread to places they would have had to fly to? Rheas live in South America, cassowaries and emus in Australia, kiwis in New Zealand ...
If to come on the table cold, place the bird in a wooden trencher, in the middle of which is fixed a wooden skewer, which should penetrate the body of the bird, to keep it upright. Arrange the claws and feathers in a natural manner, and the tail like a fan, supported with wire.
