FAMILY CLXXIX. TURDIDuSB. 1 (THE THRUSHES.) 



Primaries 10, the first short or spurious; bill generally rather 

 long, not conical, usually with a slight notch near the tip ; nostrils 

 oval, not concealed, but nearly or quite reached by the bristly 

 frontal feathers ; rictus with bristles, which are well developed in 

 most of our species ; tarsus always " booted," t. e., enveloped in a 

 continuous plate, formed by the fusion of all the scutella except 2 

 or 3 of the lowest. Toes deeply cleft, the inner one free, the outer 

 united to the middle one, not more than half the length of the first 

 basal joint. 



A large family of about 300 species, found in most parts of the 

 world, and embracing quite a wide variety of forms. Nearly all 

 of them are remarkable for their vocal powers. Their food consists 

 of insects and soft fruits. 



a. Bill short, depressed, notched and slightly hooked at tip; gonys not more 

 than the commissure; tail about as long as wings. (Myadestince.) 



MYADESTES, 531.

 c. Tarsus longer than middle toe with claw; nostrils exposed; nasal fossae

 c?. Bill much widened at base; (breast spotted). . . . TURDUS, 532. 

 dd. Bill little widened at base; (breast in adult unspotted). 



MERULA, 533. 



1 One of the most remarkable of the thrush-like birds is the Ouzel or Dipper 

 (Cinclus mexicanus Swainson), an aquatic thrush which swims (or rather flies) freely 

 under water, although not web-footed. It is a fine singer, living about mountain 

 torrents in the Rocky Mountain regions ; a similar species ( C. merula) occurs hi 

 Europe. They are now placed in a separate family, Cindidve.
