It seems like we may be down to just the 'locals' now, the feeders are only taking around a gallon a day to refill lately. I don't recall seeing nearly as many kinds of hummingbirds this summer and fall as usual and not the quantity in each type, except for Anna'a and Blackchinned. The weather has been excellent for the last week and generally nice all summer and fall, a bit cooler than normal. Did this keep some of the travelers from staying in the area? Maybe they were searching for warmer climes. Maybe their migration route shifted a little this year.
Old Guy update: Have not seen positive sign for weeks now, 'his feeder is seeing plenty of multibird action lately. I am hoping he just decided to share! Other very territorial hummers have been a bit less so lately, maybe just the season.
New phenomenon this year - for the last 2-3 weeks large quantities of gnat-like insects are getting into the feeders. I have not yet done a close exam on these insects in order to identify this latest annoyance. They may be an effect of the early rain and then hot weather. Better than bees, and they may be a protein source for the hummers - if so, fine.
