APPENDIX A Note 1, p.7. Feb. 10, 1934. At the time of writing this entry, the sexes of the birds were not known. As a matter of fact, it was the male, Brownie, Brown-eyes, B.E. or B that took the worm. It was not until October 12, 1933 (See p. 462) that the sexes were distinguished. Therefore, in these notes, up to the time of determining the sexes, the personal pronouns are wrong as applied to these birds, as also are the designations male and female. Thereafter they are correct, except, perhaps, for an occasional slip, to be expected under the circumstances. Note 2, p.10 Feb. 10/34. Their attitude toward crossing this space has not changed in the slightest--they are as much afraid as ever. As it was across this space that they had to come during the taming period, or nearly all the way across it, it now seems in retrospect the more remarkable that they should have come to me at all. Note 3, p.33 Feb. 14/34. The differences noted have proved to be con- stant, although occasionally either bird may temporarily change the carriage of its wings.
