CETTIA SERICEA. 93 
22nd, and in 1872 on the 28th of that month, the migration 
lasting quite for weeks. They nest about the last week in May. 
In places where there are many vineyards (which they 
frequent) they are known as Viriadera. Alzacola is the local 
name about • Gibraltar ; and " Cocktail " is very nearly a 
translation of it. " Rufous Sedge-Wo.rhleY," as this bird 
has been hitherto called, is a most inappropriate name, as 
they are never seen near either water or sedges. 
103. Cettia SERICEA, Natt. Cetti's Warbler. 
Favier states that " this Warbler is rare near Tangier, and 
seen on passage in February and March, to return in October." 
This, however, is quite different from my own observations. 
They certainly are not rare in spring near Tangier, where, as 
on the Spanish side, wherever there are thick bushes (gene- 
rally bramble-brakes close to water) Cetti's Warbler is to be 
heard. Perhaps many migrate ; but at Casa Vieja they are 
quite as common during the winter months as at any other 
season, and, somewhat like our own Robin, may be heard 
singing at all times. Very difficult to see in the breeding- 
season, in the winter months they do not skulk so much. 
They are excessively restless, being ever on the move ; and 
often in the winter, when hidden up in the sotos near Casa 
Vieja, have I watched them quite close to me ; but the 
slightest movement on my part sent them off to the thickest 
depths of the jungle. In the breeding-season it is almost 
impossible to catch a glimpse of one. 
The only chance of shooting them is at the nest, which is 
always placed some distance from the ground, generally at a 
height of about two or three feet, and is either situated in a 
thick bush or (when in a bushy swamp) constructed, somewhat 
like the nest of the Reed-Warbler, on the stalks of reeds and 
Epilobium. These nests are built of bits of small sedges, 
intermingled with willow-cotton, and chiefly lined outside 
with strips of the stems of the Epilobium, inside with fine 
grass, a few hairs, and bits of cotton at the top. Those 
nests built in bushes are chiefly constructed with grass and 
cotton, and are entirely lined with hair. All the nests are
