Hi there, I found this thread after searching for advice on sparrows bullying house martins.
I live in a rural village near Stirling which has colony style houses with eaves running the length of the block, which are fantastic for HMs. Its the absolute highlight of the year when they arrive, and the sky is often like a motorway with the number of birds dashing in an out busily building their nests.
Firstly I have been worried about the returning numbers this year as we have a lot less than normal, which everyone in the village has noticed. My mum monitors numbers over in the central belt and says the same. There are about 7 nests on one side of my block, all of which were occupied by HMs last year. So far only 2 have been occupied by HMs (1 of which sits above my front door) and a couple are occupied by sparrows.
That's why I'm so annoyed to witness what happened today. The sparrows had taken up residency before our wanderers returned, and are now feeding young. The empty nest above my door had been damaged and I have loved watching the HMs diligently repair this over the last 2 weeks, however to my horror I noticed the sparrows making a racket this afternoon and there appeared to be a scuffle between the birds. It looks like the sparrows have managed to fight the HMs off the nest, after they obligingly repaired it, and are now sitting guarding this nosily like a mob of hooligans lining up on the guttering and hanging off the side of the nest. There's loads of them and the HMs don't stand a chance!
I can't understand why some of the nests have been left empty altogether by both species, seems like such a shame when there are plenty of options. I guess the sparrows know what they're doing, and waited for the upgrade!
I'm not a fan of singling out certain species for protection, we often interfere and get it wrong, but I am so sad that the few HMs which made across the seas have been bullied out their nest by a thriving population of sparrows. The sparrows aren't bothered by me at all, I tried shooing them away but of course that didn't work. I came across the RSPB advice re hanging weighted strings and was looking for some examples of that in practice, so thank you Robbo for the photos in your other thread. I just wondered whether trying to hang strings at this stage might scare both species away? The HMs are quite shy, and I might make things worse for them. Is this something better left until next year, before anyone is trying to nest, and hope the HMs aren't spooked by the new obstacles in front of their nests?
Thanks, Mari
