First Documented Predation of Sika Deer (Cervus nippon) by Golden Eagle (Aquila chrysaetos) in Russian Far East
... Forest-dwelling reindeer might feel more protected from a predator flying above while hiding in the forest and move less to decrease the chances of being detected. Eagles usually attack and successfully kill ungulates in open areas (but see Kerley and Slaght 2013), and most predation events caused by eagles on reindeer occur in open areas (Nieminen, Norberg, and Maijala 2011). Ultimately, the response of reindeer to aircraft observed in this study may also depend on the occasional herding of the reindeer with helicopter performed by the herders in the study area, which may have made the animals less prone to acute responses to flights, as well as on the domestication process (Reimers, Røed, and Colman 2012). ...
"It would be fitting, i think, if among the last manmade tracks on earth could be found the huge footprints of the great brown bear" (Earl Fleming, 1958)
Green artos, what info do you have on the above flying reptile? size, when it lived and when it became extinct. What did it feed on etc.. I know what it's called as you most certainly do to, just want to see if everyone else knows, which they should.
Anyone want to take a guess what these birds are? They visited my backyard a few weeks ago and I shot this vid. Likely a male and female as it's breeding season back then. Hint... they are migratory birds.
*Pteranodon was one of many species of pteradactyls. I have argued for years that neither pteradactyls nor dinosurs should be classified as reptiles. They were both warm-blooded animals which evolved from reptiles; just as birds evolved from Coelurosauria, a particular group of theropod dinosaurs. Pteradactyls left behind no living relatives.
