Thanks Rab, that makes total sense. Ours are bringing back tons of pollen still so things are still good, and temperatures are still quite high. The drone I observed being kicked out about a month back must have been a wanderer from another colony then, as a few people suggested.no sighn of the big heave ho yet, would be intresting to see what happening around the country
I find this so very interesting - all those beeks worrying to know whether their colonies are normal or not.
There is very little connection between drone eviction and where you are located.
Eviction can coincide with a steep flow reduction, shortage of stores, very cold patch of weather, etc.
Retention can be related to supercedure, age of queen, etc.
So any colony anywhere could be throwing out drones for one or more of a variety of reasons, or the converse.
The autumnal chuck-out, readying for winter will simply be up to the worker bees - good foraging may make it later.
Indeed, some colonies seem to have a few drones all winter, although I have not experienced/observed that.
It makes those with just a very few colonies give replies which may be an isolated case, or scenario, totally out of sync with the vast majority of other local colonies.
I am sure those in Cumbria would have lost their drones when stores were running short (well over a month ago when we saw the inspector's warning letter? Last year it was happening at the end of July IIRC, but all of my (large) colonies were actively producing drones.
There is no particular correlation further than it generally happens later in the season, everywhere.
