sounds a lovely place to be,you are very lucky and sound very happy.I find great joy in watching wild life and I know some things are not very nice to witness but it is the way nature is.
I agree with Alan4711, it's worth a try, if you explain nicely. Maybe take a dog along with you once and tell them how thirsty it is!
I hope your swallows didn't fly into the new window glass looking for their nest. Have they nested under the eaves?
