For Ornithology…

For ornithology (bird watching) we have been keeping a daily bird log, but we only fill it in when we pass by, or on occasion see a bird. So, I thought it might be neat to get one of those clocks that go ding-dong in some form every hour or half hour, and that would be a queue to check outside for birds. Perhaps a sailor clock or one of those bird ones.
