R. E. Stewart 1952 <p> During the summer of 1938, detailed studies were made of the molts of the Northern Yellow-throat, <i>Geothlypis trichas brachidactyla</i>, in southern Michigan. Observations of the post-natal molt were made each day on nestlings found near Geddes Pond, one mile east of Ann Arbor. Studies of the post-juvenal and post-nuptial molts were from fresh specimens collected at Portage Lake in Jackson County. </p> application/pdf 10.2307/4081292 en American Ornithological Society Molting of northern yellow-throat in southern Michigan article
