No.07 Oriental Greenfinch

The kingfisher is a resident and drifter bird of the family Anseridae (sparrows) and is about the size of a sparrow.
In the fall and beyond, dozens to hundreds of male and female brown-eared bulbul form flocks and begin to mate in groups. The flocks are small, with a diameter of about 30 meters around the nest. They then cluster several of these small territories together to form a loose colony, which is called a loose group. If a female enters the couple's territory, the female will drive her out, and if it is a male, the male will drive him out.

Compared to the CT image of an amphibian already published in the CT bio-illustration book, even the lungs, digestive organs, and other internal organs were clearly captured, despite the large size. The interior of a bird's bone is hollow, and it is known that a pillar-like structure exists to reinforce the bone, but the tomographic images taken this time also show the hollow interior of the bone. Unfortunately, we were not able to see the detailed internal structure under the shooting conditions, but by bringing the X-ray tube and the object of observation closer together, it will be possible to capture even finer details of the shape of the bone.
