During a tour this summer up Cypress Mountain in the Cross Country Ski Area we came across a Red-shafted Northern Flicker with just its head sticking out of a nest hole. Flickers are notorious for making holes in the sides of wood sided houses. They can make quite the racket while they are doing this. The also will find the item in their territory that makes the most sound when rapping on it with that very pointed bill. Sometimes that means the sheet metal fireplace flu. Now there is a noise.
