and the precipitous rocks that overhang the sea on 

 many parts of the coast. 



It has a pecuHar fancy for breeding on any small 

 island in preference to the mainland. I have noticed 

 this particularly the case at the "Ferns" and Bass 

 Rock, together with all the islands in the Firth of 

 Forth on the east coast, and on the numerous small 

 patches of rock lying off the coast of Ross-shire and 

 Sutherland on the west. 



The case is copied from a sketch made on the Bass ; 

 the nest was placed among some fallen stones in 

 the passage leading through the Fortifications. Great 

 numbers of these birds nest on the rock, generally 

 among the buildings, or on the ledges on the south 

 side. 



The specimens in the case were obtained at the 

 Bass Rock, in May, 1867. 



TREE PIPIT. 



Case 20. 



This Pipit is only a summer visitor to our shores ; it 

 may, however, be met with in most counties during the 

 nesting season. Though possibly proceeding to the 

 north of Scotland, I have never myself observed this 

 bird beyond the Forest of Glenmore, in Inverness- 

 shire, where in the summer of 1869 I found it breeding 

 in considerable numbers. 



It has a pleasing note, and is known to bird-fanciers 

 by the name of Singing Titlark. 



The specimens in the case were obtained near 

 Brighton, in June, 1875.
