Well that is it, Bex and I have finished our cliff counting for the season. No more clambering around cliff tops totally immersed in the cliff birds lives and counting and counting. The counting of the guillemots and razorbills can be especially challenging but after a while you start to spot and differentiate between even little bits of them.
Obviously when you see them singly in the open they are easily distuiguished
Sometimes they line themselves up along a ledge making it easier to count them.
Guillemots have short tails, razorbill have longer pointed ones.
Guillemots are a browner, chocolate colour, razorbills are a blacker brown.
The white line on the trailing edge of the wing can be a give away, the guillemot has a shorter, broader line, the razorbill has a longer, thinner line.
The bill is easier to tell apart. The guillemot has a sharp pointy one, the razorbill a vertically broader bill.
