CHAP. XVI. Of the Faulcon.
A Faulcon is so strong, that when he strikes a bird, he will •ut him in two, from head to tail. A Sea-Swallow call'd Drepanis, a little Bird about Lakes, when she hears the Castrel, will rather let men stone her, than she will rise. She is wont to be sick of a disease the Faulconers call the Filandre. That is, a kind of worms not far from their reins, near to which they are wrapt up in a thin and pro∣per membrane: they are as small as hairs, and half an ell long, it may be from their first originall; unlesse you prevent them, they will eat up the principall parts and the heart. The Gyrsaulcons are of di∣vers kinds; They are some white found in Moscovy, Norway, Ireland. They are bold: If one of them be let fly at five Cranes, he will fol∣low them all till he have killed them. The food of it reserved in its Cave, it will take in order. She never wets her self with water, but onely with sand. She loves the cold so well, that she will alwayes delight to stand upon ice, or upon a cold stone: sometimes untaught she is sold for 50 Nobles. There is a Faulcon called Ru•eus, because the spots, that are white in the rest, are red and black in this kind; yet they seem not to be so, but when she stretcheth forth her wings. The cause of this rednesse is a feeble colour infused into the superfi∣cies of the body, and inflaming the smoaky moysture, which is put forth to breed the feathers.
