I hope that your Seagulls are ok Whitewave. I live in the countryside and have many different nests around my house. I have House Sparrows and Starlings under the eaves of my cottage and lots of Dunnock's in the hedges and Robins, Wrens and Blackbirds in my trees of which I allow Ivy to grow through as it's great coverage for nests.
I wouldn't be without birds, I love their song and their cheeky antics.
What is a garden without bird song and what is a seaside town without the cry of a gull?
It infuriates me to see notices about being fined £1000 if you feed a Sea Gull or Pigeon! These creatures are not vermin, they are just trying to survive.
For goodness sake, there are so many human "vermin", but they are all fed and looked after.
Lets not forget God gave us all these creatures and we are not the only living race on the planet!
