Be careful! Birds are getting older...

The bird’s age is commonly measured in calendar years (i.e. the "official birthday" of every bird is the 1st January). It means that since the 1st January 2022, birds born in 2021 are in their second year (and not in their first year). Those born in 2020 are now in their third year and so on... Keep it in mind if you specify the bird’s age in your sightings!

However, this information is optional. Indeed, the determination of age and sex is often far from obvious, sometimes impossible, or only if the bird is in hand.

The golden rule is therefore to use these boxes only when you are absolutely certain of the determination. It is better to leave them empty than to enter false information.

Thank you very much!
