Here is one of the nicest wheels we have. It was made in the 30s by our friends at the Chart of Knowledge Co., of America. This one says it's part of its Nature Study Series. I really hope we can find others in the series some day.
This is 10.25 inches in diameter and in very good shape. It includes some of my favorite birds: the Cardinal, Blue Jay, King Fisher [sic] and the Cedar Waxwing. I have seen every bird on this wheel except for the Bobolink, which I'm beginning to think is fictitious after all these years of NOT seeing one.
There is plenty of information here to attract the would-be bird fancier: nest structure, plumage, migration dates.
The King Bird's [sic] distinctive habits box says he is pugnacious and likes to chase hawks and crows. That's why they call him The King! The Blue Jay is mischievous. The Scarlet Tanager's distinctive habit is "around tall shrubs and trees". That doesn't seem very distinctive to me.
Not surprisingly, the "nature of young" for every bird here (and every bird everywhere) is "blind, naked, helpless." Poor little things.
