I hope by using the guide intensively, a lot of the disadvantages Yoav pointed out will solve. Indeed the information packed on pages makes it in the beginning hard to use. But on the other hand, where can one find so much up to date info on (ie.) waderID in the hand?
Indeed I also missed some species-accounts. I've had more rough-legged buzzards and ruddy shellducks (to name a few) in the hand than great snipes. The first one is only mentioned in the account on the common buzzard to point out the differences. But really, does one deserve a ringing-permit if he doesn't know a rough-legged buzzard has rough legs and a common buzzard hasn't?
And for the Ruddy shellduck, it outnumbers the great snipe easily on the Dutch ringing totals (329 Ruddy's and 5 great's, Op het Vinkentouw 2016). But this Ruddy shellduck isn't in the book.
Perhaps it deserves some thoughts to make a web-place for additional species accounts and where errors can be placed?
Anyway, Laurent and the translators deserve a big thank-you for this work. I will use and enjoy it a lot, I'm sure!
