We've been enjoying heavy visitation schedules recently at the hummerfeeder on our window, as they fatten up for migration. This has included many more males than seen during the doldrums of August. All of a sudden, there's a new (well, never before seen by us) phenomenon of sugar wasps chasing off the hummers when they approach the feeder. In addition to a couple of sugar wasp traps, which I'm going out to purchase right now, does anyone on MDOsprey have any other recommendations? thanks, David Strother Bethesda, MD dstrother@pop.dn.net
