Subject: [MDBirding] Autumn -- are we there yet??
As sunset approached, I saw a single crow fly over. Haven't observed any
large groups yet. But in a "normal" year (remember those?), wouldn't the
big winter roosts have started to form by now?

Climate change certainly provides an interesting opportunity to compare
the influence of day length vs. air temperature on a variety of plants
and animals.
