We've had a pretty typical year for the hummers, just starting to slow down this week a little. We have 2, 7 station feeders that hold 40 oz. each (2 1/2 qts. total) and they go thru those in less than 24 hrs. At the "peak" a week or two ago they were going thru them in approx. 12 hrs but have settled back down now. Been feeding them on the front porch here for 14 years now. Usually the last birds are seen in mid-Oct here and the latest we've ever seen them was about 4 or 5 days before Halloween. Northern middle TN. here.
