NOTES FROM THE SOUTH. 627 



In the beginning of April I saw a great many flying about 

 Trebinje, but never met with them either in the neighbour- 

 hood of Mostar or in Northern Dalmatia. 



LANIUS COLLURIO. Red-backed Shrike. 



On April 13th I observed a Red-backed Shrike sitting on 

 a thorn-bush between Ragusa and Carina, but neither before 

 nor afterwards did I see another bird of this species. 



LANIUS RUFUS. Woodchat Shrike. 



On April 17th I saw a pair among the olive-trees on 

 Lacroma, and they remained for the next few days. 



MUSCICAPA ATRICAPILLA. Pied Flycatcher. 

 On April 19th I saw some on Lacroma. 



MUSCICAPA ALBICOLLIS. White-collared Flycatcher. 

 On April 17th I met with the first pairs on Lacroma. 



LUSCINIA PHILOMELA. Nightingale. 



On April 1st we heard the earliest of these birds warbling 

 in the bushes and low oak-woods between the frontier and 

 Trebinje, and afterwards in all suitable localities both in the 

 Herzegovina and Dalmatia. 



ERITHACUS RUBECULA. Robin. 



Very common in suitable localities on Lacroma and the 

 mainland both in March and April. 



PRATINCOLA RUBETRA. Whinchat. 



On March 10th I saw one in a little vineyard on Lacroma, 

 but after that no more until the middle of April, when whole 

 flocks appeared in the island, but generally stayed but a short 

 time. In Northern Dalmatia I only noticed solitary indi- 

 viduals.
