The Goal of the Wise

In the top left margin, two large birds of prey (possibly eagles or vultures) are perched facing one another.

—the whole [carrion] wing, they were not sensing the meat thrown before them [if] they did not have a sense of smell. We have experienced also that they do not snatch birds when they are hungry—seeing [them], we presented one hen and they were not taking it, nor were they killing it. They were [known by] their head, their neck [is] through a narrow opening of the carcass, in which [they go] into the carcass to extract whatever is inside through that opening. Their head and neck are without feathers, as in most [vultures]. Concerning the manners [and] by which ways birds acquire food for themselves.

Below the first paragraph, two birds of prey are depicted scavenging a carcass. In the left margin next to this scene is the word "obserua".

The motion and operations and [ways] which birds have in the middle [of their lives] for the acquisition of food are manifold. For some, by running hither and thither and swiftly changing place, acquire for themselves [food]. Sometimes, however, [they acquire it] by biting with the beak, as crows, plovers, and rannelli small frogs or a species of small bird and the like; some by walking and not running, if by flying from place to place when they change locations for the acquisition [of food]; and by digging the ground with the beak, which are under the earth, and by biting with the beak, which are above the earth, as cranes; some by walking and fishing with the beak for reptiles which are under the earth or outside [it], which they can live [on]; they do not, however, bite with the beak to gather grains or—

In the lower half of the left column, several tiers of illustrations show various wading and marsh birds, including plovers and two cranes, one of which is inspecting a snail shell.

At the top of the right column, two storks are illustrated with the marginal caption "ciconia nigra".

—of fruits of trees or of herbs, because they do not live on such things, as are storks, those which [are] in the field and [the] middle [of the field] do not swim, and which are entirely flying [birds], and often recede from the waters so that they remain on the earth, and so that they are [found] anywhere. Concerning the diversity and by what [means] they live in the middle [of their lives]—

The diversity, truly, of the foods which they use is [a matter] of reason. Some live mostly on things from the water; [others] from the fields—namely, from grasses, roots of herbs, and seeds, fruits of trees and herbs and bushes and the like, as the manner of cranes. They dig up, however, willingly the roots of herbs and most willingly—some [live] on worms which they dig up under the earth, and sometimes on those which they find above the earth, as they speak, namely [on] beetles and other worms of birds and non-birds, which they find also upon the herbs and in the meadows and in the swampy places, and in the lands [and] fields, as are the genera of crows, rannelli small frogs or a species of small bird, plovers, and sperici starlings or starles starlings, having a long beak in the manner of crows, the greater part of whose life is to dig under the earth.

The right column features several tiers of bird illustrations. Mid-way down, a heron-like bird is shown eating a long worm or eel. At the bottom, two smaller birds are labeled "Guerzimus".
