Busy morning but no surprises

Thanks for these, Dan

Heysham Obs
A major ringing session on the north harbour wall today. Thanks very much to the harbour authorities for allowing this to take place before the weather breaks, despite the dredger rescue operation nearby. One bird had been ringed at Walberswick, Suffolk in December 2006 and two had been ringed on the Duddon estuary at Askam, either last Thursday or during the previous week. The Plain English Society have complained about the next bit so here is the re-write: 44 have been ringed during the past week (since 31/10). The maximum observed flock size has been 89. Therefore, because there were only 11 retraps in the catch of 66 birds this morning (52 unringed and three 'controls), this indicates quite a turnover of birds, as you might expect during the peak autumn migration period for this species. This proportion of about 20% ringed was also the same as observed yesterday, therefore is not due to a net-shyness bias towards unringed birds. Indeed, the impression was that all birds present were in fact caught this morning!

The high thrushes and Starlings were mainly heading north, but the general movement of grounded thrushes etc. through the bushes was to the south. A bit of a 'Heysham moment' with Starlings, but otherwise small numbers of other species with Woodpigeon a surprising absentee until a small mid-afternoon flock. Thrushes observed movening inland have been included here, rather than under 'grounded'.
