FOOTNOTES:
[1] In classification and nomenclature this list conforms to the American Ornithologists' Union 'Check-List of North American Birds,' Second Edition, 1895. L. S. Foster, New York.
[2] As this little pair dressed like twins, I could only infer which was which from the song and the actions of the two, which were quite distinct.
[3] The difference in the dress of the woodpeckers is so slight that the sexes were not distinguished at this nest.
[4] Since this paper was written, I have consulted an authority on nests, who thinks that this nameless bird was probably Hutton's vireo.
