hummers vs. wasps ...?
The wasps come to the hummer feeder & take over ... the hummers try to 'dive bomb' them but then seem to give up. Will the wasps sting the hummers, how can I keep the wasps away? The feeder is near the fish pond & the wasps also are all over the pond surface getting the water ... do they use it is nest making?
Some hummers perch while drinking & others hover (seems a waste of energy!) ... any reason?
Thanks for any info. for a novice hummer watcher!
