Hmmmm

Cool night, just below o°C but the sun came out mid morning. At around midday (air temperature +5°C) had a look at the hives (externally). There are still lots of dead bees in front of the weaker colony. Removed the entrance restictor and apart from one or two bees in the last moments of life, there was nothing to be seen or heard. I suspect this colony will not survive. I would like to look inside but don't want to cause any additional strees.

In comparison the stronger colony is a "hive of activity", well at least quite a few at the entrance enjoying the little bit of warmth the sun must be giving. Important they have these days so that they feed. During the cold periods they huddle around the brood keeping it warm by vibrating their muscles which in turn needs food as energy. Most brood combs have honey cells at the outer corners but the bees in the middle can't easily get to it. Their colleagues can pass on the message that they are hungry and this will be passed along the line and some honey then sent from mouth to mouth but for many not enough and with time these handy food stores are empty and one needs to get it from other combs. This they can only do when the temperature is warm enough. Also need these days to do the housekeeping, carrying refuse to the entrance.
