Spring must be here. Every year we have a woodpecker that comes here; AND, starts pecking on our metal furnace exhaust. He is at it this morning, first time this year. It sounds like rapid taping -echos though the house. First year couldn't figure what was causing the noise until went out side and saw it for ourselves. After a series of pecking at a rapid pace he calls, listens and pecks again. Carries on about 10 min. then quits. Does this several times during the day -- week or two he stops -- then we only see him in the big cottonwood by the house. <br /><br />Cool - it's now spring time in So. Alberta!
