When the tulips bloom in Michigan, you can expect the Baltimore Oriole.. This year we have two pair. We put out three different feeders. However, one pair kept fighting over the same feeder while a feeder near by went untouched. They leave our yard when nesting is over. We don't seem to see their young, although we have found nest in our trees. I don't know where in Michigan they spend the summer. I wasn't successful using the sight that shows range maps for activity 3 to learn what other birds pass through. Laura
