Jackdaw in chimney

This question is not answered

Jackdaws are building a nest in my chimney. Advised by a sweep I removed the cowl on my chimney and now they are moving in. I can hear knocking noises through the wall. Are they damaging the bricks? What can I do and when should I do it so I can have fires again without hurting them?

Thanks!

  • I can't imagine why anybody would advise removing a cowl because it increases draft and prevents backflow, but too late now. As above, you'll have to wait until the birds have flown the nest, then get the chimney cleared if you want to use it. Then get a new cowl. I think it very unlikely birds will damage your bricks, but keep a look out for any brick debris in the fireplace just in case - however that would suggest the bricks were already damaged and the birds have merely dislodged bits.

  • Hi Alan ! you say it is illegal to disturb jackdaws while they are nesting in a chimney, so who would be to blame if the owner of the property wants them removed because they need to use the fire to keep warm, or the sweep for removing the nest because the customer says to do so ?
