294 Mr. P. J. C. McGregor on Birds observed 



44>. Anthus trivialis (L.). Tree-Pipit. 

 So far as I am aware, the Tree-Pipit is only to be met with 

 as a migrant in April and May, returning in October. 



45. Anthus spipoletta (L.). Water-Pipit. 



Very abundant in the rocky gorges of Peristeri in sum- 

 mer, descending in winter to within a short distance of 

 Monastir. 



46. Anthus campestris (L.). Tawny Pipit. 



Is to be found in the drier and more barren parts of the 

 plain, but does not seem numerous. I only once saw a pair 

 on the higher level of Brusnik — in July, 1904. 



47. Oriolus galbula L. Golden Oriole. 



Arrives in mid- April and breeds in considerable numbers, 

 shewing no aversion to the vicinity of human habitations. 

 The autumn migration is at its height about August 27, when 

 many individuals fall victims to local gunners. 



48. Lanius excubitor L. Great Grey Shrike. 

 Observed in the plain on September 27, November 24, and 



December 13, 1904. 



49. Lanius minor Gm. Lesser Grey Shrike. 



Arrives in the first week of May and is fairly abundant 

 everywhere till August. A nestling which I kept for some 

 time assumed the black frontal stripe in December. 



50. Lanius collurio L. Red-backed Shrike. 



One of the most abundant, conspicuous, and widely 

 distributed summer visitors, arriving between the 20th and 

 24th of April. It seems to nest by preference in the tangled 

 hedges and thickets dear to the Whitethroat, but is also 

 seen in numbers in the mountain-gorges 1000 feet above 

 Monastir. I have never found anything but insects in 

 the stomach. 



51. Lanius pomarinus Sparrm. Woodchat. 



The only specimen which I ever saw was a handsome 

 male observed on April 26, 1904, when I had unfortunately 

 left my gun behind me.
