Beside the ordinarie birds which keep constantly in the country many are discouerable both in winter and summer which are of a migrant nature and exchange their seats according to the season. Those which come in the spring coming for the most part from the southward those which come in the Autumn or winter from the northward. So that they are obserued to come in great flocks with a north east wind and to depart with a south west. Nor to come only in flocks of one kind butt teals woodcocks felfars thrushes and small birds to come and light together, for the most part some hawkes and birds of pray attending them.
The great and noble kind of Agle calld Aquila Gesneri I have not seen in this country but one I met with in this country brought from Ireland which I kept 2 yeares, feeding it with whelpes cattes ratts and the like, in all that while not giving it any water which I afterwards presented unto my worthy friend Dr Scarburgh.
Of other sorts of Agles there are severall kinds especially of the Halyætus or fenne Agles some of 3 yards and a quarter from the extremitie of the wings, whereof one being taken aliue grewe so tame that it went about the yard feeding on fish redherrings flesh and any offells without the least trouble.
There is also a lesser sort of Agle called an ospray which houers about the fennes and broads and will dippe his claws and take up a fish oftimes for which his foote is made of an extraordinarie roughnesse for the better fastening and holding of it and the like they will do unto cootes.
Aldrovandus takes particular notice of the great number of Kites about London and about the Thames. Wee are not without them heare though not in such numbers. There are also the gray and bald Buzzard of all which the great number of broad waters and warrens makes no small number and more than in woodland counties.
Cranes are often seen here in hard winters especially about the champian and feildie part it seems they have been more plentifull for in a bill of fare when the maior entertaind the duke of norfolk I meet with Cranes in a dish.
In hard winters elkes a kind of wild swan are seen in no small numbers, in whom and not in common swans is remarkable that strange recurvation of the windpipe through the sternon, and the same is also obseruable in cranes. Tis probable they come very farre for all the northern discouerers have obserued them in the remotest parts and like diuers other northern birds if the winter bee mild they commonly come no further southward then Scotland; if very hard they go lower and seeke more southern places. Which is the cause that sometimes wee see them not before christmas or the hardest time of winter.
A white large and strong billd fowle called a Ganet which seemes to bee the greater sort of Larus, whereof I met with one kild by a greyhound neere Swaffam another in marshland while it fought and would not bee forced to take wing, another intangled in an herring net which taken aliue was fed with herrings for a while. It may be named Larus maior Leucophæopterus as being white and the top of the wings browne.
In hard winters I have also met with that large and strong billd fowle which Clusius describeth by the name of Skua Hoyeri sent him from the Faro Island by Hoierus a physitian, one whereof was shot at Hickling while 2 thereof were feeding upon a dead horse.
