[27] These cases would seem to contradict the statement made on p. 82 that small families occur when the young are protected by the parents. I cannot explain this exception. But what I have stated about the dependence of the birth rate on the amount of parental care is commonly true. In this connection I would quote Mr. Pycraft (Infancy of Animals, p. 214): “A careful survey of the facts shows us that the production of large numbers of eggs and young produces the same result as obtained where but few eggs are laid, and are either carefully guarded by the parents or are specially protected by some other means.”

[28] Quoted by St. George Mivart.

[32] Several examples are mentioned in Darwinism, p. 281. Wallace, however, brings them forward in quite a different connection to prove his theory of the protective duller colours of the female birds.
