194 DUTCH AND ENGLISH BIRDS. 
As a nest was found with young birds as late as Sep- 
tember in the Naarder-meer, it is probable these birds 
breed twice in the same season. Resident in Norfolk and 
Cambridgeshire. 
Genus Acredula. 
Acredula caudata (Linn.). 
A common resident in Holland, accidentally found in 
Gr. Britain on the east-coast. 
(Acredula rosea) * * (Blyth). 
A common resident in England, which I think highly 
probable never leaves the Br. Islands. In Holland longtailed 
tits with white heads and birds with striped heads con- 
stantly mix and breed together, which last thing they 
would probably not do if they belonged to different spe- 
cies. I am therefore inclined to think that so-called speci- 
mens of Acredula rosea of the continent are simply not 
quite mature specimens (as far as the colouring of the 
feathers goes) of Acredula caudata. 
Genus Parus. 
Parus major Linn. 
A common resident in Holland and the Br. Isl. 
Parus ater Linn. 
A common winter visitant in Holland occurring in small 
numbers, generally two or three, mixed with the more 
numerous troops of Parus major. It has bred now and then 
in Gelderland, Noord Brabant and Noord Holland. In 
England, if the specific distinction of Parus britannicus 
holds good, it is a rare visitor. 
(Parus britannicus) ** Sharpe and Dresser. 
Parus palustris Linn. 
A common resident in Holland and the Br. Isl. 
Parus coeruleus Linn. 
A common and numerous resident in Holland and the Br.Isl.
