at once recognizable, even if not in sight, by its entirely different 

 caw, quite unlike that uttered by the other crows, and when 

 flying, the tail extending far beyond the secondaries, made the 

 bird quite conspicuous, when in company with individuals of the 

 following species.

 $ $ 9 Berbera. 



This crow was very plentiful in many parts of Cuban and Ogo 

 as well as in Ogaden, and could always be recognized when on 

 the wing by its long secondaries, which extended over two-thirds 

 the length of the tail. It was common at Berbera, and the spe- 

 cies was represented in about every place in which any crows 

 were seen. It was quite tame like most birds in Somali-land, 

 and there was no difficulty in obtaining specimens. One pecu- 

 liarity of this species and of the preceding, and one I do not 

 remember to have noticed among other crows, was its habit of 

 soaring. A number would rise in the air, generally in the middle 

 of the day when the heat was excessive, and ascend in more or 

 less extensive circles, until they became mere specks in the sky 

 or disappeared altogether. Often during this performance they 

 would join, or be joined by, vultures, eagles or hawks, and then 

 the entire company would sail along, circling as they went, the 

 crows cutting across the paths of their large companions in utter 

 disregard of their movements, or without apparent fear of a colli- 

 sion. While thus soaring I never noticed any movement of the 

 wings, the birds propelling themselves onward and upward in 

 the same mysterious manner as is observed of the birds of prey 

 when similarly engaged.

This curious starling was only seen twice, at our camp at 

 Gelalo in the middle of Toyo. Plain, and again, a flock of them, on 

 the southern edge of the Haud. They were rather shy and 

 approached our camp in order to drink at the rain pools which
