Hello,

me and my classmates are doing a project about how we can get birds away from sonic anemometers and we want to know are there smells birds don't like?



Your sincerely

I think it's probably fair to say that we don't know. It's worth noting that, based on comparative anatomy we think the sense of smell is much more developed in some avian groups than others. So if there is a generic smell that birds dislike, it may only be effcetive for some species.

If you search the internet you will find a lot of commercial products that go on as a liquid and claim to have smells repellent to birds on drying. However, I have not been able to find any peer reviewed evidence concerning their efficacy so it is perhaps hard to disentangle true effect from marketing hype.
