March 24 /68/ Proportion of sexes
Gould believes strongly that males in excess is usual rule with Birds. When the bird-catcher first catch nightingales for first fortnight all are males, so severe contest when ♀ first arrive. Believes the male general with migratory Birds. Has known that with snipes & believes it general - with many birds as tit larks & the well-known case of Chaff finches sexes separate.
(As young ♂ resemble ♀. Error is probably be the other way)
