An exciting month coming up!!! The month of dinosaurs. I remember when JP first came out and I caught dino fever. I watched it 3 times at the cinema and countless times since. This is why I will be releasing 2 Jurassic park/world related prints in the next 2 weeks. Sit tight for more details!!

morning, Audubon Society of Portland conservation director Bob
Sallinger headed out to band peregrine falcons on some of our city’s
bridges. This photo shows Bob holding a juvenile peregrine while mom
keeps a close eye on them. This is Audubon’s 22nd year of monitoring
Portland’s growing peregrine population.
Yes, that’s an osprey! They are not here year-round, but will migrate through here. We do have lakes, so they do have opportunities to fish! Their wingspan is amazing (almost 6ft) and have bluish/gray feet. This guy was found on the side of a road with no injuries, but is a bit emaciated. All he needs is lots of fish and a quiet place to recover.
Microraptor is a fairly famous little dinosaur due to its clear four wings on its fossil. It is known from numerous (over 300 specimens), very well preserved fossils from Liaoning, China, in the Jiufotang Formation. Microraptor lived in the Aptian age of the Early Cretaceous, about 125 to 120 million years ago. Microraptor was distinctive at the time of its discovery for having long, pennaceous feathers, the kind that we typically associate only with birds - solidifying the link between birds and dinosaurs. It was about 1 meter long and only would come up to the calf of a 1.8 meter high person. It had a thick covering of feathers all over its body, with a fan on the end of the tail. Its fossilized melanosomes, or pigment cells, have been analyzed, and found to have black, glossy coloration and iridescence like modern starlings.
Microraptor, in having four limbs, and a tail fan, was probably able to glide between trees. In fact, the hind wings would have hindered its ability to run on the ground, and would have been confined to an arboreal environment. However, whether or not it could actually fly - meaning, power its own movement through the sky - is fairly controversial. It may have had too primitive of shoulder joints to flap; however it did have a shoulder girdle that could have allowed the wings to be positioned vertically, allowing upstroke of the wing. Wind tunnel experiments have been conducted that Microraptor could actually glide fairly well, regardless of its ability to power its own flight.
To glide, it has ben suggested that its hindlimbs and forelimbs were on different levels, such as on a biplane. It could have then glided by launching from a perch, swooping down, and then landing on another tree. Through this model, Microraptor could have potentially achieved powered flight, in addition to gliding. There are some who criticize this hypothesis, though these studies have been insufficient at best. Whether or not the biplane model is correct will require more testing and analysis. On the ground, Microraptor would have dragged its feathers behind him, and only by keeping the wings elevated could it have avoided damaging them. Thus it did not use its forelimbs to capture prey. It may have parachuted from trees to ambush prey on the ground from short distances. Thus, this creature was a mainly arboreal species, spending most o fits life in the trees.
This has profound implications for the evolution of flight in birds. It indicates that avian flight evolved from predominantly being powered by all four limbs to being only powered by the forelimbs. Studies of Archaeopteryx, modern birds, and dinosaurs with long primaries on their feet such as Pedopenna indicate that bird flight did undergo this shift. Microraptor has been preserved with remains of food in its stomach as well- specifically it could feed on mammals, lizards, and even tree-perching birds. It also could have eaten fish, due to the evidence of fish scales found in the abdomen. Thus, Microraptor was an opportunistic hunter, feeding on those things it could find in its habitat and glide down to catch. It may have been nocturnal, however its iridescent plumage indicates that this is unlikely.
My girl Allie giving a big smile to the camera, she has so many facial expressions it’s unbelievable!
She is comfortable sitting on her perch in the display arena now, so much so that she’ll tuck her foot up and start to nod off! She now hops from the glove to her perch and is gradually grasping the concept of stepping up onto the glove.
She has a strop here and there but it’s completely understandable, but she has a great attitude towards me and training and so she should be flying in no time!
