If you're looking for cheaper prices for birdseed, check out Ocean State Job Lot.
They have 50lb. blackoil sunflower seed and 25lb. thistle for $20.00 each.
They also can have cheaper prices for suet (when the season calls for it) as well.
Probably not uncommon, I just never saw it before. Easily 5 times recently hummingbirds have shown up at my feeder and landed on the feeder or the iron post that it hangs from, stopped flying and perched for a bit.
