This year I was asked to participate in a contaminants survey. I believe it was NY, NJ, and PA. They were interested in Black Ducks, Mallards, Teal, and Canada Geese. I was asked to take a picture of each bird, submit it, show on a map where it was harvested, and a biologist would contact me within 48 hours and let me know if they wanted the bird. Each bird was to be kept intact (not dressed) until they contacted me. If they wanted the bird (mature birds only) they would send a cooler and prepaid label. I was skeptical as I did not want a pile of whole birds in my fridge. The whole process went well though and the biologists usually contacted me within a few hours. I sent quite a number of whole birds in. The results of the study are to be shared with me later this year.
I've never been asked to do a wing survey.
