1. The oriole is entirely of a yellowish green. This bird is not visible in the winter. It is seen in the greatest numbers at the summer solstice, and takes its departure when Arcturus rises. It is of the same size as the turtle. The malacocraneus always perches upon the same place, and is captured there. This is its appearance: its head is large, and has the form of cartilage; its size is smaller than the thrush; its beak is strong, small, and round; its colour is entirely cinereous; its feet are strong, and its wings weak; it is generally captured by the owl. 2. There is another bird, called the pardalus, which is generally gregarious, and a single bird is never seen. Its colour is entirely cinereous. In size it resembles those already mentioned. Its feet are strong, and its wings are not weak. Its voice is frequent and not deep. The collyrion lives on the same food as the blackbird, and in size much resembles those just named. It is generally taken in the winter. These birds are visible all the year round, and so are those which live in the neighbourhood of towns, the raven and crow; for these are always visible, and neither migrate nor conceal themselves. 3. Of the jackdaw there are three kinds, one called coracias, which is as large as the crow, and has a red beak; another is called lycius; there is also a small one called bomolochus; there is also another kind of jackdaw in Lydia and Phrygia which is web-footed. 4. Of the lark there are two kinds. One dwells on the ground, and has a crest. The other is gregarious, and not solitary. Its colour is similar, though it is a smaller bird, and has no crest. It is used for food. 5. The ascalopas is generally taken in enclosed gardens. It is of the size of the domestic fowl, it has a long beak, and in colour resembles the attagen. It runs quickly, and is very partial to the neighbourhood of mankind. The starling is variegated, and is of the size of the blackbird. 6. There are two kinds of ibis in Egypt; the white and the black. The white live in all the rest of Egypt, but are not found in Pelusium. The black occur in Pelusium, but not in other parts of Egypt. 7. One kind of scops, called brown owl, is seen throughout the year, but it is not eaten, for it is not fit for food. Others occur sometimes in the autumn, when they appear for one, or not more than two days. They are eatable, and are highly esteemed. They differ in no respect from the brown owl, except in fatness; and they are silent, whereas the other has a voice. No observations have ever been made on their mode of generation, except that they appear when the west wind blows. This is manifest. CHAPTER XX.
