THE STILT- WALKERS. II 



them very timid. We learn from Badeker that the eggs of this species are from three to four in 

 number, short and broad, with a sand-coloured glossy shell, marked and dotted with a darker shade. 

 These are deposited in a slight hollow in the ground amongst short grass or stones. We are 

 unacquainted with farther particulars respecting the nidification of the Cream-coloured Courser. 



THE TROCHILUS, OR CROCODILE WATCHER. 



The Trochilus, or Crocodi-le Watcher (Hyas sEgyptiacus, or Trochilus), differs in many 

 essential particulars from the above group, to which, however, it is nearly allied. The body of this 

 bird is compact, the neck short, and the head moderately large. The beak is not more than 

 half as long as the head, compressed at its sides, and drawn in at the margins ; the upper mandible 

 rises gently from the base, and again curves downwards towards the tip ; the lower mandible is 

 straight ; the leg is high, bare, and but three-toed ; the wing, in which the first quill exceeds the rest 

 in length, is so long, that it extends as far as the tip of the iounded tail. The secondary quills 

 are also unusually developed. In this very beautiful bird, the top of the head, the broad cheek- 

 stripes which unite at the nape, a wide stripe on the breast, and the long slender back-feathers 

 are all black ; the eyebrows, throat, gullet, and entire under side are white, shading into pale reddish 

 brown on the sides and breast, and into brownish yellow in the region of the rump ; the feathers 

 on the shoulder and upper covers are pale slate-blue or grey; the quills, with the exception of 

 the first (which has only a light border at the base of the outer web) are black in the centre and 

 at the tip, the rest of the feathers being white, thus forming two broad stripes to the wings, which 

 have a very fine appearance when fully spread. The tail-feathers are blueish grey tipped with white, 

 and decorated with a black stripe. The eye is light brown, the beak black, and the foot light grey. 

 The body is about eight inches and a half in length ; the wing measures five inches, and the tail two 

 inches and three-quarters. The female is but little smaller than her mate. 



Herodotus gives the following quaint account of the supposed strange friendship between 

 this species and the crocodile : — " All other beasts and birds," says that old Greek writer, " avoid 

 the crocodile, but he is at peace with the Trochilus, because he receives benefits from it, for ' when 

 the crocodile gets out of the water and then opens his jaws, which he does most commonly towards 

 the west, the Trochilus enters his mouth and swallows the leeches which cling to his teeth. The 

 huge beast is so pleased with this service that he never injures the little bird." This well-known 

 account is still current in Egypt, with the addition of another tale traditional among the Nile boatmen 

 concerning this bird, which they call the Zic-zac, in imitation of its call. The crocodile, they say, 

 while reposing on a sandbank, often falls asleep, quite forgetful of his bird friend, who is busy within 

 his large mouth clearing his teeth from their troublesome leech appendages. The Zic-zac, finding 

 the huge door closely shut upon him, gives the crocodile a sharp reminder of his presence by striking 

 his spurs into the mouth of the monster, who immediately sets the prisoner free. The Hyas 

 ALgyptiacus is met with throughout all the country watered by the Nile, and on the shores of all the 

 rivers of Western Africa. It is very doubtful whether any stray specimens have really visited Europe 

 as has been stated ; this species, according to our own observations, being strictly stationary 

 in its habits, and only quitting one sandbank for another when compelled to do so by the rising 

 of the water. In all its movements this brisk and pretty little bird displays great ease and rapidity. 

 During the course of its flight, which is never long sustained, it keeps close to the surface of the river, 

 and frequently repeats its shrill whistling cry. Towards every living creature the Trochilus manifests 

 the same utter fearlessness which he exhibits towards his neighbour the crocodile, over and around 

 whose large body he constantly disports himself on the sandbanks, and gleans off the insect parasites 

 that torment him. We can distinctly affirm that we have ourselves repeatedly seen the little creature
