I think I have read some where that they are after the linseed oil in the putty , your next post may be "My windows have fallen out".
The windows that they are attacking have been there since 1935. The putty is as hard now as it's ever going to be. Their attention is clearly directed at the glass. The one pane that I replaced ten years ago does not seem to be of any interest to them. They have removed some small pieces of loose putty, but that would seem to be more with the intention of providing themselves with safer working conditions. Initially, I wondered if they were taking spiders off the glass, but they've been at it for two days now.
It's not just me they're irritating, there's some sparrows in the hedge that come out now and then to shoo them off when the noise gets too much to bear.
