The Hawfinch irruption in Surrey 2017-18
I have been collating material for a paper on the Hawfinch irruption in Surrey for future publication in the Surrey Bird Report. As this is unlikely to see the light of day for a while, I thought it worthwhile making the first draft accessible, not only because it is still fresh in the minds of those who witnessed it, but also in the hope that there will be plenty more information forthcoming from observers who will hopefully read it. This is very much a first draft.
