seen in the foot of the Cuckoo or the Woodpecker {Fig. 272). 

 The term applied to the group is that of Scansores or 

 climbers. The fourth is composed of those birds whose beaks 

 are so wide and gaping that they appear as if cleft ; hence they 

 are named Fissirostres. The Swallow or Swift, in chase of 



their insect prey, are famihar examples 

 of this structure. A much mahgned 

 bird, that also feeds upon insects, exhi- 

 bits this peculiarity. We allude to the 

 Goatsucker {Caprimulgns Europceus, 

 Fig. 265), which popular credulity has 

 '^ ■ accused in Italy of sucking goats, and 



here of sucking cows, and inflicting a fatal distemper upon 

 weaning calves. We have thus four tribes of perching 

 bu-ds : — 



I. Tooth-billed, Dentirosires. 

 II. Conical-billed, Conirostres. 



III. Climbers, Scansores. 



IV. Gaping-billed, Fissirostres. 



We shall now notice some well-known individuals of each 

 of these tribes, though necessai-ily with great brevity, devoting 

 our space principally to those which are natives, in preference 

 to the more brilliant inhabitants of foreign climes.

 Of which we in the ballad read." — "Wordsworth.

 blance in habit, and in the curved projection of the upper 

 part of the bill, to the birds of prey. " The Grey Shrike," 

 says Mr. Yarrell, " feeds upon mice, shrews, small birds, frogs, 

 lizards, and large insects ; after having killed its prey, it fixes
