The tickers dilemma! You hear a bird but don't see it. Can you tick it for whatever list you are keeping?
Obviously, some species are very difficult to see i.e Quail, Corncrake to name but two. For me , if it's a LIFE bird it HAS to be seen.
What about a County tick? Same criteria for me.
BUT...How about a year tick for a Patch. Mmmmm.
You hear it, you recognise the song/call, so it's there right...on the Patch...but you can't SEE it.
What to do?
This scenario happened to me this morning at Sammy's Point. I had great audio of a Thrush Nightingale (a first, the song that is) but no visual (as Jack Bauer would say). This was supplemented by a Marsh Warbler...same scenario.
Answer...not sure...! Let's face it...who cares anyway...it's my/your list!!
