the Birds of Peking. 23 



14. AcROCEPHALUS ORIENTALIS. 



This species arrived at the end of May and was very 

 common during the summer. It is a very noisy bird, and 

 frequents thick reed-beds over water, where, perched at the 

 top of a high stem and singing a loud harsh song almost 

 continuously, it is a very conspicuous object. 



15. ACROCEPHALUS BISTRIGICEPS. 



Schmidt' s Reed-Warbler was also common. It arrives 

 at the same time and lias much the same habits as the pre- 

 ceding species. 



16. ACROCEPHALUS AGRICOLA. 



Common at the same time as the last two species. It 

 is found further away from water than the latter. 



17. Arundinax aedon. 



A summer visitor to Peking. This bird is often kept in 

 captivity by the Chinese, who carry it about the streets 

 tethered to a twig by a fine silk thread fastened round the 

 neck. It seems to become tame within a day or two of its 

 capture. 



18. Phylloscopus fuscatus. 



The Dusky Willow- Warbler was common for about a 

 month, from the middle of April. I did not notice it after 

 the middle of May, by which time the reproductive organs 

 were still very little developed. It probably does not breed 

 at Peking. 



19. Phylloscopus proregulus. 



Large numbers of this species passed through Peking on 

 migration in April and October. I saw none in the inter- 

 vening months. This was the earliest of the Warblers to 

 arrive. I shot the first specimen on April 6th. 



20. Phylloscopus superciliosus. 



Common for about four weeks in May, arriving at the 

 beginning of the month. Also fairly common at the be- 

 ginning of September. This bird keeps to the tops of the 

 trees and has a dissyllabic call-note — very loud for such a 

 small bird.
