I think the Marquis of Tavistock's scheme a very good one, and I 
am looking forward to the time (when 1 have been able to collect a few birds 
and house them decently — when materials are procurable) that I shall be in 
a ])osition to place my n.ame on the List of Club P>reeders — I have been serv- 
ing with the colours, but am now discharged.

HYBRID GREENFINCH x ROSEFINCH. 
RECORDS OF BIRDS WHICH HA\'E BRED IN CAPTR'ITY. 
Sir, — As Dr. Hopkinson asks that members should enable him to make 
the above list as complete as possible, by forwarding particulars of any cases 
omitted, perhaps I may be allowed to draw his attention to a greenfinch x 
Siberian rosefinch cross which is not included. An account of the occurrence 
will be found in B.N. for 1916, pp. 206 and 256. Though the evidence was 
then stated to be not quite explicit enough, an inspection of the skin of the 
hybrid (which was unfortunately subsequently killed by another bird) satisfied 
the Committee, and a medal was awarded. (See B.N. K)i6. pages 206, 256 and 
1917 pink inset, pages 22 and 31. 
I am 
Yours faithfully,

ARRIVAL OF SPRING MIGRANTS. 
The accompanying tabic shows that our visitors this spring were rather 
later than usual in arriving on our shores (Esse.x). This, no doubt, was owing 
to the bleak, not to say severe, weather prevailing in April till quite the end 
of the month.
