Hawfinches galore!

The incredible numbers of Hawfinches across southern England has dominated the migration picture this week, with thousands of birds thought to be involved and there does not appear to be any let up.  Many areas where Hawfinch would be a rare bird if a single bird appeared have seen staggering numbers, with the largest count being 115 over Steps Hill in Buckinghamshire on a single morning.

Possibly the most unusual record this week was a Razorbill about as far inland as it is possible for a seabird to turn up, at Draycote Water in Warwickshire, but unfortunately it was found dead the following day.

Despite a continuation of westerly winds in many areas this week, few new vagrants from North America were found, though Blackpoll Warbler on North Uist, Grey-cheeked Thrushes in Co.Cork and on Scilly, and a fly-through Cliff Swallow at Spurn Point were seen. 

Rare birds from the east as a result have been relatively few with Pallid Swift at Spurn and it or another further up the Yorkshire coast and a Black-throated Thrush on Fair Isle being the highlights.  A scattering of Dusky and Radde’s Warblers, Olive-backed Pipit and Little Buntings were found too, fairly typical birds seen at this time of the year.

A brief switch to much colder northerly winds this weekend will see further arrivals of Redwings and Fieldfares along with Song Thrushes and Blackbirds and finches, in particular Chaffinches and Bramblings from Scandinavia.  Wildfowl too will be on the move with more Pink-footed, Barnacle and Brent Geese and Whooper Swans arriving from their arctic breeding grounds to spend the winter in the UK. The first Little Auks of the autumn may appear, mostly in Scotland, though some may penetrate into the North Sea down the east coast of England as far as Norfolk or Suffolk.

After the brief spell of northerly winds over the weekend, westerly winds are again set to dominate next week which may curtail the arrival of many traditional migrants, though we could see further American vagrants – American Robin and Rose-breasted Grosbeak are often among the later autumn vagrants found.
