Female Yellow-bellied Sapsucker at Point Pelee
The characteristic pattern of horizontal rows of small shallow holes made by theYellow-bellied Sapsucker.
These holes ooze a resinous sap which traps insects. The woodpecker can then return and feed on both sap and insects.
It is the sap from these holes which attract the Ruby-throated Humming Bird which usually migrates to this area later than the woodpecker.
