My guess is that this may be one of those years when sapsucker wells--those horizontal, sap-oozing holes made by Yellow-bellied Sapsuckers--may be of more importance than usual in the northern part of the ruby-throat's range.

Red maples are flowering in southern New England, but I suspect feeders may be of prime importance for those birds that have made it north already. John DAVID . . .

Hi David, I wonder what they are eating way up in Canada already. High bush blueberry (Vaccinium corymbosum) (yes, white flowers) and pinxter flower or pinxter azalea (Rhododendron periclymenoides, syn: R. nudiflorum) are some attractions and they are not flowering yet in southern New England.
