observed in Switzerlana . 161 



It will be understood that, unless otherwise stated, my 

 remarks refer to the districts mentioned in the title, and are 

 merely the results of a short and limited experience in a 

 country where the natural features tend to upset broad or 

 general statements. For instance, the avifauna of the western 

 portion of Lake Leman is far richer than that of the upper 

 end, especially in those migratory species which frequent 

 open cultivated ground and flat shores. If my residence had 

 been at Geneva, the character of my list would have been 

 considerably modified, for no migration of importance ap- 

 pears to take place by the Valais, on the way to or from the 

 south. 



The greater part of this paper was written in November 

 and printed in December last, but I have endeavoured to 

 work in the results of the observations of two months more. 



TuRDUS viscivoRUS, Linn. 



The Mistle-Thrush was not seen or heard near Lausanne 

 until the middle of March, and I do not think it is a resident. 

 In the Jura it was plentiful — though very shy — from May 

 till September ; and birds were observed above Vevey till 

 the end of October. 



TuRDUs Musicus, Linn. 



The Song-Thrush is a migrant, and was not identified near 

 Lausanne until April 13th, although it may have arrived a 

 little earlier. Instead of being the familiar bird which we 

 are accustomed to see on our lawns and hammering snails on 

 the gravel walks, the Thrush, in Switzerland, is a shy, 

 retiring species, frequenting the forests on the mountain- 

 sides above 2000 feet, and seldom visible, except for an 

 instant, as it darts, high in the air, from one tall fir to 

 another. On Chaumont, where it was in full song in May 

 and June (inferior in melody to that of English, and especially 

 of Scottish birds), I never saw adults on the ground feedingj, 

 although later the young were noticed hopping along wood- 

 land paths. The nest is placed in the spruces, and is not 

 easily found. In early autumn the Thrush is found on the 

 fields, and for a short time on the vineyards ; and I saw a
