I haven’t seen our annual influx of Hummers, here in NE Florida, yet. It was 20F, night before last, killed lost of new growth and blossoms, but there will be more. The Hummers and other migratory birds seem to be hanging out a couple of hundred or so miles south of here (I am north- west of Jacksonville) until some inner swareness of the exterior weather tells them OK GO!
If I put feeders out too soon, then the yellow-jackets (wasps) and ants and mold and fungi find them before the birds do. The insects and have no trouble finding feeders that are moved regularly, or even irregularly.
It is a daily bother to keep up with feeders, but if you create dependent birds, then you must. So don’t start what you can’t keep up. To not feed dependent birds is the same as starving them. Not just the hummers, but the birds you feed other foods, as well. —-Granny Bear
Researchers say warmer weather may be encouraging hummingbirds to migrate to North America 12 to 18 days earlier than in years past.Johnson said. extremely early arrivals, he said.
