from that date their numbers were increased rapidly by fresh 

 arrivals ; and towards the middle of the month the topmost 

 leaf of every cactus hedge, which forms their favourite perch, 

 was sure to be occupied by one of this species. They seem to 

 prefer plains, as, although they extend occasionally into the 

 low hills, I never remember seeing one in the high mountains. 



54. Lanius collurio. 



Arrives a great deal later than the preceding species (the 

 first I saw not being till the 10th of May), and is not so nu- 

 merous. They also differ considerably in their choice of lo- 

 cality, preferring the low hills and mountains, and being 

 rarely found on the plain. The stomach of one I shot was 

 full of the elytra of beetles and a small lizard. 



Note. — Lanius meridionalis is included in Dr. Salvadori's 

 list of the birds of Sardinia; but he has since rectified his mis- 

 take in Sharpe and Dresser's ' Birds of Europe/ in their ex- 

 cellent article on the Southern Grey Shrike. It, therefore, 

 cannot be included in this list. 



55. Parus major. 



By far the commonest Titmouse in Sardinia, where it is 

 resident ; and during spring their loud call-note is to be heard 

 ringing through every orchard. 



56. Parus ater. 



Scarce ; confined to the forests on the mountains. 



57. Parus CjEruleus. 



Moderately common. In the winter they come down about 

 the plains, where I never remember having seen them during 

 summer. 



58. TlCHODROMA MURARIA. 



Rare. 



59. Troglodytes vulgaris. 



Extremely common in the mountains; but I never remember 

 hearing or seeing one on the plains. 



60. ClNCLUS AQUATICUS. 



It surprised me very much to find this bird absent on many
