THE WILLOW-WARBLER. 



Phi/Uoseopus trochilus (L.). 



The Willow-Warbler arrived along the whole of the south 

 coast, but chiefly on the western half. 



A single bird was reported as having been seen in Ports- 

 mouth, Hampshire, at the end of January, but the first 

 record of the arrival of migrants came from the Scilly 

 Isles, where one or two passing birds were seen on the 

 9th of March. Between that date and the 30th stragglers 

 were evidently arriving, particularly during the last six or 

 seven days, and were reported from widely separated 

 localities, chiefly in the western half of the kingdom, as far 

 north as Cheshire and Nottinghamshire. The first immigra- 

 tion occurred on the night of the 30th of March and was 

 followed by others between the 2nd and 5th of April. All 

 of these seem to have been small, but together must have 

 contained a considerable number of birds, for the species 

 rapidly became distributed over a large portion of the 

 country, as far north as Lincolnshire on the east and 

 Lancashire on the west side. 



The second immigration, which also seems for the most part 

 to have included small numbers, took place on the nights of 

 the 8th, 9th and 10th of April at the lights in the Channel 

 Islands and off our south coast, but was hardly noticed 

 inland, though northward-bound migrants were observed on 

 the two last-named nights at one of our west coast lights. 



The third movement, which was of larger dimensions, 

 landed along the whole of the south coast between the 12th 

 and 17th of April, being recorded at the same southern lights 

 on the nights of the 13th and 14th. The larger proportion
