I've just spent 2 full days working in gardens around Darlington (Teesside,UK) and saw two honey bees in all that time - both of them spotted in adjacent gardens within 10 mins of each other. This despite warm temps, sunshine and a huge burst in flowering plants, including many dandelions. I've also been watching trees in blossom and not seeing a single honey bee on them. I've now seen a total of 5 HBs since landing in UK on Nov 26 2012.
Things are not that bad here - yet. Still, it is worth keeping an eye on what may cause problems elsewhere. Today I came across an interesting if deeply troubling article describing some possible causes. the article seems based on reasonable scientific grounds so it deserves attention. The problem for me is that I cannot see what I or other beekeepers could do to make things better. It seems that all we can do is to sit and watch. Scary!
