|In Southern Michigan, Orioles prefer American Elm trees 7:1 over any other species of tree.|
|My guess is that the American Elm's unique twig pattern and spacing offers the best possible foundation for the Oriole's woven nest.|
I wonder if anybody has ever made the connection between American Elms and Oriole nesting success rates.
A foundation laid true-and-square is a house half built. See, nothing political about that!
