THE WOOD-WARBLER. 



PhylloscopiLS sibilatrix (Bechst.). 



The somewhat scanty data available renders it difficult to 

 trace the movements of this species, especially as it did not 

 occur at any of the lights. 



The earliest arrivals recorded were in Dorsetshire and 

 Staffordshire on the 10th of April. Some had reached 

 Cumberland on the 22nd and Northumberland on the 24th, 

 and by the end of the month the species was thinly scattered 

 over the country. 



Their numbers had increased generally by the middle of 

 May, and they were settling down to nest. 



Many pairs were reported to be building in Devonshire 

 between the 15th and 21st of May. Nests with eggs were 

 found in Surrey on the 20th, in Hertfordshire on the 24:th 

 and one ready for eggs in Northumberland on the 21st.
