10 x 10 Challenge

The challenge is a simple one – you have ten hours consecutive to record as many
species as you can in a single ten kilometre square.

It is quite a lot like a bird race but on a smaller and more compactBarn Owl
scale.  All usual bird race rules apply – birds can be heard or seen
but must be in the square, not seen/heard from the square and in an
adjacent one.  Around three quarters of you team must record it for
the species to count – easy if that’s one of you, both of you for two,
two out of three, or three out of four.

On 2nd May 2015 a team of three (Steve Blain, Matt Burgess and Darren
Oakley-Martin) had a crack at TL14 between 5am and 3pm.  They scored
94 species and set the initial benchmark for other teams to beat.

A repeat  in TL14 on 1st May 2016 with a team of three consisting of Steve Blain, Matt Burgess and Andy Grimsey stretched the total to 99 species missing one other species by a couple of minutes  so we know the 100 is possible.

The same top team has got 29th April 2017 in the diary already… but which square?

Pick your square and see how many you can get:
