Who's knocking on my house?

You'll know when they're back by their drumming on your roof vents or the side of your house (I spotted the first one this year on Feb. 22 pecking a telephone pole). You may love them or hate them when they cause damage to your house. Northern flickers, also known as woodpeckers, are migratory birds that winter in the southern United States and arrive back here around March.

What can you do about...
