SIRS,–While it must be well known t h a t t h e ” fledgling “Guillemot (Uria troile) and Razorbill (Aha tarda) resemble in all essentials of their coloration t h e adults of their respective species when in summerplumage, extending even to t h e white stripe in front of t h e eye in t h e case of the Razorbill, it does n o t seem to have been recognized t h a t this plumage answers to t h e ” mesoptyle ” or second generation of down-plumage in other birds, e.g. t h e Tawny Owl.

British Birds – how it works
BB 2000 Ltd, the company that owns and publishes British Birds, is run by a board of directors, all of whom are volunteers. The company employs two full time staff – Roger Riddington is the journal’s editor while Hazel Jenner manages subscriptions and administration – and three part-time design/editorial staff.
The company is wholly owned by The British Birds Charitable Trust (BBCT, registered charity no. 1089422). Neither the company directors nor the trustees are paid for their services, providing their time and enthusiasm because they passionately believe in the value of BB. The Company is managed with a view to making a small profit which can be donated to the Trust to help fund its charitable work.
Over the past six years, this, combined with donations from other sources, has enabled the Trust to give almost £70,000 support to a variety of conservation and educational projects ranging from rat eradication on seabird islands to the study of cuckoo migration, as well as assisting young birders develop their interest.
A full list of projects is given here. The Trust is seeking to expand its charitable endeavours and would welcome donations from like-minded organisations and individuals.
