I should like to explain that this work, being, with one or two insignificant exceptions, a record of my own observations only, it has not been my intention to make general statements in regard to the habits of any particular bird. In practice, however, it is often difficult to write as if one were not doing this, without its having a very clumsy effect. One cannot, for instance, always say, "I have seen birds fly."
