Bird Notes from the Zoological Gardens.



VII. Experiments in change of color due to moult.


VIII. Adaptability. The plasticity of animals. How great a

factor is this in domesticating new kinds of animals ?


IX. The leisure of animals. How is this acquired ? Being

acquired, how is this employed ?


X. Instinct, habit, and the development of intelligence.


XI. The possibility of breeding insectivorous and other

beneficial kinds of birds to re-stock a given region or to

increase native birds, as has been done in the case of

fish, by the United States Fish Commission.


A temporary laboratory and aviary is being equipped, and

preliminary work will begin with the instalment of a large

number of native and foreign birds early in September. Mr.

Worthington has procured the services of Mr. William E. D. Scott,

Curator of the Department of Ornithology at Princeton Uni¬

versity, as Director of the proposed work. Mr. Bruce Horsfall

has been engaged as chief assistant and artist. The corps of

assistants and workers will be increased as the plans of the

Worthington Society develop.
