Number One
My top 10 natural history events of the last five years has reached its conclusion...
1. The Hawfinch irruption in Surrey, 2017-18
It had to be, didn't it - you do not get to witness many unprecedented ornithological events in a lifetime. The Hawfinch irruption of 2017-18 was truly remarkable. The first suggestion that 'something was going on' started in early October, when larger than usual numbers of this big-billed finch were being recorded across the (mainly) southern part of England. This in itself would have been enough to rewrite the perceived status of migrant Hawfinches, but it didn't stop there. Many stopped off to winter, and here I was very lucky indeed. Firstly, I had the time. Secondly, I had the bit between my teeth. And thirdly I lived right in the thick of it, as the largest Hawfinch gatherings ever recorded in Britain decided to haunt the yew-clad slopes of the North Downs in 'my' part of Surrey.
I spent a great deal of January, February and March 2018 hunting Hawfinch. It became an obsession and it paid off. I located birds at over 25 localities and recorded 6,327 bird days. On February 22nd my day total was of 705 individuals. On March 13th my morning was enlivened by a single flock of 600 birds. Within a three-mile radius of the Mole Gap I am confident that there were over a thousand present. Minimum. Bramblehall Wood became a site of celebrity, hosting hundreds between early February until early April, and enticed many birders to traverse the undulating, muddy footpath to join in the Hawfinch-fest.
