5. LOCDSTELLA. 113 



It is not known that the sexes differ in plumage, or that the 

 autumn moult produces any change of colour. Birds of the year 

 are said to be less rufous on the upper parts, and paler underneath. 



Savi's Grasshopper Warbler appears to bo sparinglj' distributed 

 throughout Central and Southern Europe, including the British 

 Islands. Eastwards it has been found as far as Palestine. It also 

 breeds in some parts of the southern shores of the Mediterranean. 

 It is said to be a resident in some parts of France, but probably the 

 greater number migrate to North Africa for the winter.

 typically LocustcUine ; upper mandible dark brown, under mandible 

 pale horn- colour ; rictal bristles obsolete. Wing rather short and
