Oregon State College Campus -- December 5, 1941 10:30 to 12: Noon.
Weather cloudy, no wind near ground, and cold (breath fogs on exhalation)
Albino Robin - (partial) - This robin was seen feeding on the vines on the
of the Dairy building. during two different class periods
in Ag 203. He was seen on four instances--onee for five minutes at
50 feet.
The distinctively bright white areas were:
1. The top fore part of the head and on the cheeks
2. Each wing had the primaries and secondaries white with the
wing coverts the usual gray black color
3. The tail feathers are white.
As you probably have noticed the white areas on this Robin are located
at the extremities: The head, tail and wings. Could this possibly mean that
the albinism in this instance could be caused by some form of error or
mistake in structure of the circulation or nervous system in these areas?
Poor circulation in some way, may have caused this.
