I realised when I came around to updating this that I completely missed posting about the last wash trip - we caught 238 Sanderling on Heacham beach. A very nice catch, although none of the geolocater birds were caught. Next wash weekend is in a fortnight but I'm not sure if I will be able to make it because I have a new job!
The RSPB are hiring me as a research assistant, looking (loosely) at the impacts of windfarms on Golden Plover. This involves radio tracking Golden Plover, habitat surveying and a lot of transects. Given that I'll have to be walking 20-25km a day, it's going to be pretty hard work but a lot of fun. I'm also now on the look out for anyone in scotland who does interesting ringing for my days off(!)

Windy days
The wind was too high to attempt catching again, but I filled the feeders up anyway - the fat ball that went up after dark on thursday had been completely consumed by friday lunchtime!
The wash trip a few weekends ago was a good success - 177 Oystercatchers on the Saturday morning (all of a good mass) and 2 oystercatchers and a knot on Sunday. These Oystercatchers were not in such good condition, weighing far less (although obviously the sample size was small and a pair of Peregrines had chased most of the birds off the beach by the time we fired). We also found a dead oystercatcher on the beach with the sharpest keel imaginable! It displayed arrested moult (where the bird has stopped growing feathers half way through its moult and instead retains its old ones) - leaving us in little doubt that this bird had starved to death.
There has been interesting research on waders collected by ringers* during harsh winters. Some waders (such as Grey Plover) weigh less on capture compared to a 'normal' year - they appear to be struggling to find food resources enough to put on enough weight. Other waders (e.g. Dunlin) instead increase their mass in colder weather - if they put on more mass then they are at a lower risk of starvation.
I am looking for some wader and/or seabird ringing for this spring/summer - please let me know if you've heard of anything. Must not be too expensive and preferably last more than a month.

Roudsea (back home)
I arrived in Cumbria at my mother's house on tuesday afternoon, after a relatively painless 6 hour journey. This morning I went ringing with my trainer (Jim) at Roudsea - report on the 01229 ringing group page, along with photos!
Tomorrow I'm off to the wash (at last!) for some long awaited wader ringing.

New years' catch
We got back yesterday after spending new year in Istanbul, immediately filled the feeders and then waited for the birds to realise there was food available (getting up at 7 is not a problem when you're still in a time zone 2 hours ahead!).
Putting the net up this morning but it was a little bit of a disaster - first the guys didnt reach quite far enough, then the net wasnt tense enough, the pegs didnt go into the ground properly, the net fell over (which of course led to some time leaf extracting). Finally (about 10 mins later than I would have liked) I got the net up. Typically, the next thing that happened was that a pigeon flew into the net, bounced, and this somehow managed to snap one of the guys so that the net fell over again...
After all that we only got a handful of birds - 3 bluti, 1 greti and a nuthatch (who was beautiful). I think I will wait a few days so that more birds find the feeder before catching again.
