The unprecedented numbers of Hawfinch in southern England are now well documented, but this week I came across reports of a huge Hawfinch flock near Box Hill in Surrey, totalling at least 250 birds. These birds were found by Steve Gale who also got Peter Alfrey in on the act. Peter’s account of coming across this mega-flock of hundreds of Hawfinch is well worth a read and is here. Realising that this may be a once in a lifetime experience to see a huge Hawfinch flock in the UK I visited Ashurst Rough Wood, just east of Box Hill Country Park, this morning. There are a number of wooded hills in the area, with stands of Juniper among the deciduous trees.
As I made my way up to the local high point of Juniper Top I could hear Hawfinch calling in the woods, I had brief glimpses of 2 flying birds and found another pair perched up in bare branches. Most of the birds were lower down, feeding and flying between Ashurst Rough Wood and Bramblehall Wood. This valley was bursting with Hawfinch activity! I spent 90 minutes here and there was hardly a moment when I was not watching or listening to Hawfinches. Birds would fly between the two woods, sometimes as individuals…
.. but often in small flocks:
Occasionally larger flocks of birds, one nearly 50 birds strong, would swirl around the tree tops, or fly across the valley:
One such flock passed right overhead and the birds settled in the treetops, high up on the slope behind me. The woods were then filled with the calls of vocal Hawfinches, both the hard “ptik” call and the softer “zih” call. The sound of calling Hawfinches drowned out all other birdsong, was I really in England?! Scanning through the treetops also revealed flocks of Hawfinches perched up in bare branches before they dropped down to feed:
I estimated that I saw around 150 Hawfinch in total, based on counts as the small flocks gradually made their way south down the valley. However, with so many flocks swirling around the true number could easily be significantly higher. The views of the birds were usually in the medium distance and always in flight or perched, I saw no birds on the ground. However, this was a fabulous birding experience, 90 minutes of continuous Hawfinch activity, at times I felt surrounded Hawfinches, both in sight and in sound. Just incredible!
