Do you mean it should be Motacilla yarrellii rather than Motacilla alba ?

M. a. yarrellii

Our bird is essentially a subspecies of the White Wagtail Motacilla alba (there are many subspecies), subspecies yarrellii. The correct form then is Motacilla alba yarrellii.

The continental bird, which we occasionally get in the UK, is Motacilla alba alba and is called the White Wagtail.

OK I see. So do I need to

OK I see. So do I need to change the Sci name - or is it OK as is, just down to the species level?

No need but could do

It’s perfectly correct as is but I would be tempted to change it just to make sure someone else doesn’t sneak in with yarrellii.

"Do you mean it should be Motacilla yarrellii..."

"Do you mean it should be Motacilla yarrellii rather than Motacilla alba ?"

There are some who would argue for this! Most follow the decisions made by 'official' taxonomical bodies though, and at present most of these treat Pied Wagtails as one of the subspecies of Motacilla alba - as described by Ray.

Don't worry about posting a new ID giving the subspecies (unless you want to), your ID is correct as it is.

Thanks for all the info - I have changed it to include the subspecies - 'just for completeness' as it so often says in my maths text books...
