Andrew,
You are now a little south of me. I saw a drone in one hive yesterday. I have heard reports of another beekeeper with some drones. There are dandelions blooming in protected areas not in the fields. I am seeing fresh nectar in the hives but, that may have all been from a week ago. The 20 degree temps set some things back.
It is probably another week or two before the earliest swarms. Plus, the winter may have been hard on ferral colonies.
Tom
