This is a Yellow-bellied Sapsucker which was just released recently from NEWC. One of many species of woodpeckers, Yellow-bellied Sapsuckers will drill holes in trees by repeatedly tapping with their beaks in order to consume the sugary sap inside.They live mostly on the eastern side of North America, migrating down to the tip of Mexico in the winter and up to the middle reaches of Canada in the summer. You can tell one of these birds has been around by the neat row of holes, called sapwells, that they leave in the trees they feed in.
