 very strong, the upper mandible toothed and abruptly hooked at 

 the tin; both mandibles distinctly notched. Wings short, rounded. 

 Tail long. Tarsus scutellate on the outside as well as in front. 

 Si vs alike. 



Specie- about 100, found in most parts of the world, remarkable 

 for their vigor and pugnacity. Their habits, corresponding with 

 the form of the bill, are similar to those of birds of prey, for which 

 reason they were placed by Linmeus among the Accipitres. They 

 have a remarkable habit of impaling small animals on thorns and 

 leaving them there.
