Species Specifics: Downy & Hairy Woodpeckers
Many people have a hard time differentiating
between two species of woodpeckers that visit our backyard feeders.
Both downy (top picture) and hairy woodpeckers (bottom picture)
have white backs, black wings with white spots and black and white
streaked faces. The males of both species have a red patch on
the back of their head and the females do not. The only obvious
difference between the downy woodpecker and the hairy woodpecker
is size. Downy woodpeckers are about 6 long and their bills
are about half the length of their head. The hairy, whose bill
is almost as long as its head, is about 9.
Both downies and hairies drum to announce territory and to attract
a mate. They rarely accept a manmade nest box. The male and female
of both species spend 1-3 weeks excavating a nest hole
the downy more often in dead wood, the hairy more often in live
wood. No material is added to the nest. Both species lay 4-6 white
eggs right on top of the woodchips. Both males and females incubate
the eggs about 12 days, the males incubate at night. Downy babies
are in the nest about 21 days and after fledging are cared for
by the parents for up to 3 more weeks. Hairies leave the nest
after 28-30 days and are on their own a few days later.
Downy and hairy woodpeckers predominantly feed on wood-boring
insects but both species will visit suet feeders and feeders filled
with sunflower seeds or peanuts. Hairies, however, are not as
common at the feeders as their cousin the downy woodpecker. Youll
often see more than one pair of downies around your feeders because
they are not as territorial as the larger hairy woodpecker.
