Oxford Bees

Bearding

An early morning viewing

I went to the visit the bees at my out-apiary this morning. I took the lids off the hives but left the brood area alone (except for Hive F) because the air temperature was cool. Everything was finished by 0630.

A side effect of looking at hives in the early morning is that all their flying bees are still in the hive. These are the bees which are most likely to defend the colony. As a result the bees seemed noticeably more angry when I opened the hives.

All the hives have plenty of space, with the possible exception of E.

Hive D. The hive floor had evidence of a lot of activity: comb building; hatching of brood; Varroa mite drop and a couple of dozen antennae. The antennae are interesting. Gareth says that when brood are ejected from the nest the antennae are pulled off first, where they fall to the hive floor. The body is then removed and will be disposed of by undertaker bees away from the hive. The brood may have been diseased or have been chilled. I would expect disease - specifically the effects of Varroa and their diseases. This hive needs further inspection into the brood nest. In any case, this is the hive where I was having difficulty with the Queen excluder so I ought to check that all is well.

Hive E. There seems to have been bearding yesterday. Bearding is when bees gather in large numbers outside the hive. This behaviour allows more space to cool the hive and suggests overcrowding. There were still bees outside the hive this morning looking wet and unhappy from the overnight showers. The hive floor had several splotches which I assume are bee poo. They may be pollen which has become wet. If they're poo then this suggests dysentry. Bees normally evacuate outside the hive. I need to read about dysentry and maybe have another look in the hive. I didn't look at the brood comb so I don't know whether there is more poo on the comb.

Hive C. There are signs that there's been a lot of activity in the hive. There are quite a few Varroa on the hive floor. This hive has a super which can be taken off.

Hive F. This is the recently established colony which swarmed from Helen's Top Bar Hive. There are still lots of Varroa on the hive floor but the rate of drop seems to be decreasing. This may not be a good sign because they're probably reproducing inside brood cells. It will be interesting to see how this colony fares. They have plenty of space. I get the strong impression that this colony is more aggressive than the others.

Hive G. This is the recently established colony which was caught as a swarm on the tree in front of my apiary. I gave them a Commercial hive with a super on top - and a Queen excluder. They have built loads of comb including new comb in the super. This shows a preference for building vertically through the boxes, rather than across the brood box as we might want. The colony looks very healthy. It has plenty of space and is dropping very small numbers of varroa.
