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



to be a migratory movement in the first week of April, when 

 considerable numbers may be seen in a limited area. 



17. Daulias luscinia (L.). Nightingale. 



Arrives regularly about the 12th or 13th of April, and 

 breeds in great numbers, especially in the dense vegetation 

 which fills the lesser gorges. Never seen after August 30. 

 It is in demand as a cage-bird. 



18. Sylvia cinerea Lath. Whitethroat. 



Arrives about April 23 and breeds in great numbers, 

 shewing a preference for the tangled hedges of whitethorn, 

 honeysuckle, and dog-rose, which are also the favourite 

 haunts of the Red-backed Shrike. It disappears in the first 

 week of October. 



19. Sylvia atricapilla (L.). Blackcap. 



Common on migration in spring and autumn. In 1903 

 I observed the first specimen, a male, on April 4, and on the 

 10th, after a heavy fall of rain, there were many in the 

 willows along the Salonika road, all males, so far as I re- 

 marked. A certain proportion remain to breed, especially 

 in the villages in cooler situations, but I have also found 

 nests in gardens in the town of Monastir. 



20. Eegulus cristatus (Koch). Gold-crested Wren. 



Is found wherever there are fir-trees. On November 4, 

 1903, I came across a small troop in a bushy gorge below 

 Krstovo, near the level of the plain. 



21. Regulus ignicapillus (Brehm). Fire-crested Wren. 

 On November 12, 1903, I shot one from among a flock of 



about twenty on the outskirts of the town. 



22. Phylloscopus trochilus (L.). Willow-Wren. 



The earliest date on which I recorded the arrival of the 

 Willow- Wren is March 30, 1904, but the birds did not 

 appear in numbers till April 15-19, almost invariably after 

 stormy weather accompanied by rain or snow. Until 

 April 25-29 they swarm among the willows and then dis- 

 appear for the summer. In 1903 they arrived in numbers 

 on August 30. There was a rush on September 13, from
