S I R S , — I read Mr. Dunlop’s interesting article ” On Incubation ” in your May number (Vol. V., pp. 322-7) with much interest, a n d also the letters from Messrs. J . Lewis Bonhote and C. L. Collenette in your June issue (Vol. V I . , pp. 29-30). I do n o t agree with Mr. Bonhote in his remarks re the breeding of domestic pigeons. I am willing to grant t h a t in the majority of cases the incubation period in domestic pigeons commences on the laying of the second egg, b u t this is n o t a universal law. In domestic pigeons, as in the wild Columbarian races, the female lays her first egg and then allows a full day to elapse before the second egg is laid. If the female was the only factor as regards incubation, that first egg would n o t be incubated b u t merely stood over a t night until the second egg appeared, a n d then incubation would begin and both the young ones would be hatched simultaneously on the twentieth day from the laying of the first egg.

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.
