Re: Sam Welles and the history of an idea

For some early references to birds as arboreal, flying dinosaurs, try these
two:

Beebe, C. W., 1915. "A Tetrapteryx stage in the ancestry of birds," Zoologica
New York 2(2): 39?52.

Beebe, [C.] W., 1938. "Why Do Birds Have Scales on Their Feet?" New York
Zoological Society Bulletin 41(1): 20?22 [January?February 1938].

and, if you can find them,

Abel, O., 1911. "Die Vorfahren der Vögel und ihre Lebensweise," Verhandlungen
der Zoologische und Biologische Gesellschaft Wien 61: 144?191.

Abel, O., 1919. Die Stämme der Wirbeltiere, Berlin & Leipzig: xviii + 914 pp.

I've only seen excerpts from the latter two. Would like to see more someday.
