where have the hummers gone?
I've been feeding hummers successfully for 8-10 years. I maintain the feeders religiously. This year the hummers arrived pretty much on schedule - about 6 weeks ago. I've seen 10 or 12 birds at a time at the feeders daily UNTIL 2 days ago. Now they have simply disappeared. The feeders are clean, water is fresh, no ants, no spider webs, no cats, no chemicals. This has never happened before. I am totally without a clue as to what could have happened. Any ideas out there?
