"On a walk through the woods you might spot rows of shallow holes in tree bark. This is the work of the Yellow-bellied Sapsucker, an enterprising woodpecker that laps up the leaking sap and any trapped insects with its specialized, brush-tipped tongue. Attired sharply in barred black-and-white, with a red cap and (in males) throat, they sit still on tree trunks for long intervals while feeding. Yellow-bellied Sapsuckers aren't regular bird feeder visitors, although they are fond of suet feeders." --Cornell Laboratory of Ornithology website: www.allaboutbirds.org
