Dear Brian:

You asked:

Seeing as how the migrants are coming in slowly, is there a possility they take advantage of the (always) earlier blooms to our south and give us a slow spring migration??  As far as songbirds go.

Experiments with birds in planetariums and similar controls seem to indicate that prime mover for migration is day length. However, we all know that birds fly, so anything is possible.
