Bird in the extractor fan duct
Plus 3 more
The outside panels of an air duct broke so a bird was able to get into the extractor pipe hose for the cooker hood. I had to replace the extractor fan hose and the external air duct. Thankfully the bird got out okay and I was just left with a feather and a bit of nesting materials in the pipe. Frightened the life out of me as didn't know what was making the noise in the kitchen
