The Wildlife Trusts have a fantastic spotter chart available to use for marine month. You can see which birds are in your local costal area... a lovely way to pass some time but if you want it to be really useful, you can log your spots on iNaturalist for some local cities science and/or sea bird tracking projects.
You can download the spotting chart here.
You can find iNaturalist here (or if you're on a phone, download it from the app store).
