widely distributed winter visitor, breeding locally

Pauu’s: The Tufted Duck is observed every winter in 
some part or another of the Metropolitan area. [ 
strongly suspect that wild birds occasionally join the 
wildfowl on the Serpentine and other ornamental waters, 
and it is a more or-less regular visitor to the larger 
reservoirs, Kingsbury, the Welsh Harp, and so forth. 
I have seen this bird on the Penn Ponds in Richmond 
Park; it frequents at times the large lake in Wimbledon 
Park; whilst I have records of it from sheets of water 
in the Wembley and Northolt districts. Some localities 
are much more favoured than others, whilst the numbers 
vary a good deal in successive winters. It is just one 
of those species that may be casually met with in winter 
on almost any large expanse of water anywhere within 
our limits. ‘The Tring Reservoirs, some thirty miles 
from London, are a favourite winter resort of the Tufted 
Duck, and it is very probable that some of the individuals 
seen on the waters of our northern suburbs are wanderers 
from this locality. On the Essex side I may mention 
Wanstead as a resort of this species. 
Those Tufted Ducks that winter in the British Islands 
migrate to them in October or November, and retire 
in March and April. The bird migrates at night, and 
during its stay with us is not only gregarious, but often 
consorts with other species, and frequents fresh water 
as well as the coast. Its habits are much the same as 
those of the preceding, but it is more nocturnal, and
