Pinging you guys. Think you might find this interesting.
It does not explain the anecdotal reports that I'm hearing that the problem is mostly affecting migratory colonies used for pollination. I'll have to re-read the article, perhaps there might be an "angle" whereby stationary colonies are just that more stabalized, they are not affected as much. In the bee club wintering poll, I can say that just about everyone with up to 3 hives (these would all be stationary), had all come thru the winter.
I now have 3 colonies, all stationary in the same spots for 4 years. All made it thru the winter, and one in particular. This one hive is full to the brim - it has the population a normal hive might have in late July ( it took me getting stung in the ear to determine this! they stung me thru the veil where I guess my ear was brushing up against it). I'm sure I'm gonna see some swarming in the future from this hive, although I added the first honey super to give them some more room and hold off swarming if possible.
