Just off the top of my head, one way of doing this is by the number of
recorded sightings i.e. vagrant equals <10, rare <100, uncommon <1000,
common >1000+, or something like that, depending on your context, place,
birds etc.

Another way is to link it to the particular habitat type, such 'vagrant:
few records in appropriate habitat', 'rare: rarely seen in appropriate
habitat', 'uncommon: occasionally seen in the appropriate habitat',
'common: expect to see in appropriate habitat', and 'very common: you'll
be kicking them out of your way!'

Hope this helps.

Does anyone know if there is a standard definition of the terms Common,
Uncommon, Rare.

We are in the process of trying to update some brochures and attempting
to assign a frequency of occurrence to the bird species.

This is traditionally done with the the notations C=Common, U=Uncomon,
R=Rare, V=vagrant etc.

Here I have at least 8 various publications and checklists, all of which
give a different definition to these terms.
