Swift Nest being destroyed

Afternoon.

Can anyone advise?

We have two swift nests in our house (either side under the eaves)

Today we have noticed that one of the nests appears to be being broken up:

Is this normal?

  • Thanks Robbo.
    Not sure if we have house sparrows. To be fair my thinking that what we have are swifts to now discover they are house martins shows you my level of knowledge on ornithology!

    Funny you should
    Mention the woodpecker though as we do have one in residence. Frequently appears in our apple tree.

    I’ll do some investigating on the house sparrow possibility.
