I think It's best to refrain from comment on Andy's last sentence
I know some of them are said to be good for green woodpeckers and spotted flycatchers (and owls and bats), but I've never seen much in a cemetery.
Probably being over-sensitive but I confess to find birding in such places slightly unnerving ( not to say 'spooky' which would probably be as inappropriate a use of terminology as Andy's).
What would happen if a 'mega' turned up in a cemetery and hundreds of twitchers arrived? Would some sort of restriction be in order?
Would it be distasteful to take a photo of the said rare bird if it perched on the grave or gravestone of someone recently deceased?
This an area of birding etiquette that seems to have been overlooked.
Does the club have any members who are in the clergy? If not, I shall have to look up the subject on Google.
