I'm doing some research into the diet of magpies and carrion crows in conjunction with GWCT. I know that lots of folk will be trapping and shooting them at this time of year. I'd be really grateful if you could send me 2/3 feathers pulled out of a dead crow or magpie's wing - the bigger the feather the better. I can then run an analysis of the stable isotope ratio in the feathers or better still of any blood in the feather shaft and get an idea of their diet level, looking to see what their level of predation on nestlings and eggs may be.
It is helpful to know the date that the bird was killed and a postcode for the area or more precise details if you are willing to supply them.
I'm happy to send you stamped addressed envelopes to post feathers to me.
Any questions or comments, do drop me a PM.
Thanks for your help with this and please do circulate the request.
