Some feed on native berries, fruit, nuts and seeds. Sapsuckers feed on tree sap as well as insects. Behavior - Woodpeckers peck into trees in search of food or to create a nesting site. Drumming usually occurs in the spring on metal or wood resonant surfaces. It may occur a number of times during a single day, and last for days or months.
Most woodpeckers live year-round in the same area.
They are very persistent and not easily driven from their established territory. Reproduction - They nest in tree cavities, holes in buildings, or other cavities. They have 4 to 8 eggs. In the summer, woodpeckers peck for larvae. In the fall and spring, many kinds of insects go into openings to hibernate for the winter, but move around when cold nights are followed by warm days.
