February 2018
The hefty Hawfinch invaded the British Isles in numbers this winter from North-Eastern Europe giving all a great chance to observe this elusive woodland species.
The influx last October continued well into November with birds settling down over the winter period usually in areas rich with Hornbeam. So the opportunity to see this large and exotic finch should not be missed this winter, before the birds return to their breeding grounds most likely in Russia.
Irruptive movements were first observed with flocks of about 10 to 45 birds moving South during visible migration watching,  'Vizz-Migging',  at Old Hunstanton in the latter half of October.
It is thought that t
his year's southwards migration from central and Eastern Europe coincided with the arrival of Storm Ophelia which headed eastwards from the Atlantic.  Strong and swirling anti-cyclonic winds pushing many of the migrating Hawfinches into the UK.  Also the  invasion could indicate a successful breeding season of the Russian population closely followed by a lack of suitable food as the passage into the British Isles occurred over quite a long period.
There is historical evidence of sporadic large scale winter influxes into Norfolk mainly during the nineteenth century but these have rarely been seen  in recent times. There is now less than 800 pairs of Hawfinch breeding in the UK, the species being in continual decline, but surprisingly the Dutch population is very healthy from which many in this invasion may belong.
Migration data on this species is very thin on the ground due to the Hawfinches wary elusiveness, arboreal habits and irregular movements. Ringers therefore have been unable to get their hands on them in significant numbers to generate reliable data. Surely a Hawfinch is sturdy enough to carry a latter day satellite tagging device? 
As ever  Lynford Arboretum  holds good numbers each winter with 17 on the 10th the birds gathering prior to  roosting in conifers here.

We obtained great views of the species at Great Massingham Church yard where up to 15 birds have regularly showed on Yew here. The attraction appears also due to an assault course of massive bird feeders in the large back garden next door and adjoining the Yew hedge. It should be noted that Common Yew leaves and seeds are highly poisonous to livestock and humans but obviously not to Hawfinch and Mistle Thrush which were avidly feeding on them. The pleasant and fleshy aril contains the poisonous seed  but even so we have heard tell of a Cornish bloke who to this day eats the aril spitting out the kernel and seed thus avoiding immediate death...  Two birds were also attracted to  Yew near to the Holkham Park main gate earlier this month.
