Coming out. Again and Again.

I was away from home today, so at 6.30am when I got up for work I duly skyped into our 'incubator' to see if any of our bees were up and about. Nothing. That seemed odd. I checked again at 7.30. Nothing. Definitely Odd. 

At about 10.30 I logged in again and saw BCW tending to the box, refreshing the honey-water and helping to upturn a bee that was obviously struggling to get up. I assumed it was TLB (TinyLittleBee) whom we added to the box yesterday. But then she texted me to say that LBB (LittleBigBee) was in trouble and not well. It was not news I wanted to hear - he's only been in our care for 8 days. I dread this moment, wondering if it's something we have done or caused. (We did, for example, add some sugar water to the 'ward' a few days ago).

LBB was struggling to move around and cope with the undulating floor of the nest area; and refusing any kind of drink. He was dragging his sorry body clumsily about the box, barely making any progress whatsoever. He got stuck in the small gap where we plant the lavender stalks. It was very sad to see. We agreed that BCW should move him to a small separate tub so protect him from falling over and getting stuck. He rallied a little, appeared to drink from some soaked kitchen paper, but ultimately crawled to the edge of the tub where he has been still since for many hours. We will wait 24 hours for a final verdict.

Meanwhile, TLB, who had already started to inherit from LBB's behaviour, and benefitted from his helpful presence, appears to have gone from strength to strength. She climbs over the moss in the nestbox with great ease; she patrols the perimeter of the outer tub over the stones behind the nestbox; she hauls herself up the pine cones. Just over a week ago she was a still and lifeless as LBB is now - her recovery is miraculously remarkable.

Her routine, during the main part of the day at least, consists of patrolling the outer tub for short periods of time, then returning to the nestbox, sometimes to feed or scratch away in the moss - behaviours we still don't fully understand. This evening we've seen her come to the pollen in the outer tub, walk over it, then return to the nestbox; it's not obvious that she's collecting pollen, but it is obvious that she is heading straight for it.

Also, I say patrolling the tub quite deliberately: she is not exploring like she did initially - appearing to map out the box by going over and over its various sectors. Rather, her behaviour is quite deliebrate, following a short path that either involves checking the pollen or nectar supplies, or touring round the edge of the tub that encloses the back of  the nest box. Then she heads straight back in again.

Quite what triggers her to come out and perform this routine is not obvious to us, other than she seems to do it regularly. So it seems this is not a response to a nest attack (even though we have observed this behaviour in our outdoor hive). One of my theories is that it's part of the standard behaviour to check what's happening outside the nest. While we have not observed this to the same extent in our outdoor nestbox, we have from time to time seen a bee sitting in the entrance/exit and not actually leaving the box. I wonder if this happens more often than we realise (our CCTV would not really trigger the motion detect if the bee doesn't come right out of the exit). 

This would explain something that has puzzled me: how do the bees know, when they spend their time in a nest that they keep at 30 degrees, when to come out in the morning as the temperature changes. The only sensible theory is that they come and sense what is happening outside the nest at regular intervals, triggering a chain reaction when the time is right for foraging. 

Is TLB teaching us how bumblebees manage their working day?

House on fire

I think before writing this update it's useful to recap where we are with our indoor bees. All of our indoor bees have been rescued from the garden - all of them have had some kind of wing problem which has prevented them from being able to fly. This means they can't feed unless they were to stay in their own hive.

But I learnt my lesson with the first one, trying to put her back in the hive twice. An hour later she was back out again on the lawn, destined to prey or die of starvation. 

So, we created an indoor environment to house our disadvantaged. It started off as an ordinary ice-cream tub but has pretty much evolved into a full scale incubator with indoor nest box, infra-red heating and "daylight" lighting. And of course, 3 video cameras! 

indoor "incubator"

So, at the time of writing we've had four disabled bumblebees come into care. In chronoligcal order (often the best), they are as follows:

• Holly - confirmed female - very small, missing left wing and left middle leg, and twisted body
• BLB ("Big Little Bee") - confirmed male - now deceased - same missing wing and leg as Holly
• TLB ("Tiny Little Bee") - unconfirmed female - actually just slightly larger than Holly - 1 broken right wing
• LBB ("Little Bigger Bee") - unconfirmed male - one missing left wing

We added LBB to the "incubator" last week and discovered that he got on really well with Holly - neither of them moidered each other. Since then LBB has been very busy in his new world - scooting from the nestbox to the outside and back again with regular fervour. 

Meanwhile TLB was in isolation in her own tub as we monitored her strength. It's hard to believe that this miniscule creature has recovered from a state of apparent death to darting around her box, climbing on lavender and feeding herself from the natural nectar rather than the honey water we freely provided for her. As her strength obviously continued to build, we took the decision that it was safe to introduce her to the other bees with some initial supervision. 

We are pleased to say it went very well, and just like LBB she has spent her time chasing round the big box, often in the footsteps of LBB. (Apologies for the picture quality - it's an iPhone screenshot from Skype over 2G!)

LBB and TLB explore together

Also like LBB, she has (at least initially) developed  a routine of coming in and out of the nestbox itself to explore the outer surroundings, and then head indoors for some relaxation and recovery. Quite often, in fact, this seemed to be in synchronisation with each other. At one point LBB even tipped TLB upright when she fell over on her back. What a wonderful thing to see. 

Finally, here's a picture of all three inside the nest box, getting along like a house on fire.

 3 bees in a boxWe are really hoping, that since bees are eusocial, allowing them to co-habit will actually be beneficial for them and help them develop or carry out their meaningful roles. So far, so good! Though I do wonder what chaos tomorrow will bring!

Yes, gravity still works...

It's tricky when things turn out not quite as expected and there's a whole variety of things to report, so to be brief here's a round up of today's events and findings:

• We have some quick responses from the Bumble Bee Conservation Trust on the ID of some bee pics we submitted. The most exciting of these was a possible Red Shanked Carder - which is like a Redtail but apparently has red hairs around the pollen baskets. Ours did, although it was a male, so strictly did not have pollen baskets. The verdict is indeed it was a Redtail - we are told by the BBCT they often have red hairs. This seems to contradict their own ID information which says they are black. So, glad to have clarification but yet another source of frustration in trying to ID the bees.
• Our ID of some Tree bees was confirmed as well as Early Bees, so it's great to have a positive on that and some photos to match. Also my ID on the Garden Bee (where I got the really close up face photos) was confirmed too. I thought maybe some kind of cuckoo bee, but the expert says not. 
• Finally, nothing conclusive on the "camouflaged" bee I found in the ditch alongside the Garden bee mentioned above other than some kind of cuckoo. It is probably either a Gypsy Cuckoo, Field Cuckoo, or Barbut's Cuckoo. I actually favour the latter due to the extra light brown band on the lower thorax and given it was 2 feet away from the garden bumble bee (which it typically attacks) there's a certain serendipty to it. 
• We confirmed we have a hedgehog visiting the garden with a 5 second CCTV clip from 4am in the morning of him crossing the garden. We suspect he is going for the tray of bird seed which goes down rapidly! And it explains the opening under the fence that has been mysteriously created. We don't mind him coming as long as he stays away from the bins!
• We also discovered a cat on the CCTV getting on top our bee hive, between it and the shelter roof! It shook the box a bit and knocked the thermometer off, but all the cameras and bees seemed to remain intact, which is a minor miracle. Can't say I'm too happy about this particular event; cats are generally a nuisance to the rest of the wildlife and the lawnmower!
• More to report on the behaviour of bees in their last moments. We tracked down the 3rd bee that has appeared on "hive corner" where two dead bees rest and discovered it went their of its own accord and over the course of 2 hours was finally laid to rest. Extremely intriguing behaviour to see it choose its final moments in the corner where the other (that we know of) departed bees also lie.

There is also good news to report on how our new disabled bees are doing with their indoor care. The smallest and weakest which appeared to die made a slow recovery and appears to continue that recovery with each passing day. She is too small and frail to join our other special care bees, but it's amazing to see her near miraculous discovery. Today for the first time she explored some cut lavender placed in her box and appeared to try taking nectar from it. This is the first time since being in our care that she has made such a large effort to get food of her own accord; and of course it will be the best type for her. We watch with interest. 

And finally, littleBigBee was added to Holly's nest earlier in the week and from the word go they got on charmingly. There appear to be no adverse affects or domestic incidents so far! LBB is very funny - he warms up in the nestbox, feeds a little, then scoots out and zooms around the the outside area; he particularly loves to climb over the roof of the nestbox and check that gravity still works. Which it invariably does.

LittleBigBee and Holly meeting for the first time

Once he is satisfied that the outside world is more-or-less still outside and still as he left it, he heads straight back into the nestbox with great purpose and shoots round the outside edge back to the "warm end" (lit with infra red). He repeated this route as a matter of course, but lately has started shortcutting his exit from the box and has now entirely created his own one way system in and out of the nest box ; all highly enteraining, if strictly unnecessary. It is unlikely to be down to health and safety given the way he behaves on the roof, which would put any of Matt Allwright's Rogue Traders to shame. 

Our delight is that he is habiting both worlds - going to rest and sleep and groom inside the nestbox and coming out of it at other times to - well, whatever it is he does, which is run round the whole area, climb everything there is to be climb, drink everything there is to be drunk. He is very much a boy. This is unlike BLB who after a few days came out of the nestbox and never really bothered to go back in it. It seems, however, that LBB has figured out the relationship between the environments we have created and his natural instincts in the wild. Obviously we are thrilled with this. 

Down but not out...

It's been a busy few days with more bees coming into care. There on the grass was a stranded bumble - still - silent. 

It looked liked it was a bufftail or vestal cuckoo and on closer inspection it had both wings - but the right one was damaged - sort of "folded". 

found on the lawn - damaged wing.Of course, it couldn't fly. Actually, I say of course, but this is not necessarily a given. There are reports that bumbles can fly with as much as 50% of the wings missing. But that's "edge damage" as opposed to "structural damage" which what we have here. Little bee can't, for example, join the front and rear wings together with her special "hooks", owing the bend. And that's another thing, we're not 100% sure she's a girl or a boy.

The ice cream tub was summoned and duly mossed and honey-watered. And for a while it was looking good, even though when she tried to take off she managed only a slightly sustained hop. Not being entirely sure of her constitution and origin we decided on an overnight quaratine before contemplating addition to the main indoor nest, occupied by Holly. 

We were glad about this decision. The next day came and little bee was less well. Slow, lethargic and by mid morning unmoving, keeled over, with all the memories of the untimely death of BLB. We took her indoors to wait the long 24 hours that we felt we needed to be sure. 

Thank goodness we did - the next day some signs of life. A little twitching; antennae probing; sufficient energy to drag herself away from the heat of the laptop, though not to consume any drink. In the end BCW accidentally spilled some honey water on the kitchen towel and finally little bee quenched her thirst. With new energy, she heaved herself onto the moss and bedded down for the night, while we moved the tub over Holly's infrared lamp. This maintained a temperature somewhere safe around 24 degrees. 

After another night, she still had life signs, though barely impercetible. Perhaps if she was humanoid she'd be four score and twenty; creaking at the joints; wheezing and failing. Still, she dragged herself around the tub a little. She's a brave fighter. And we, the helpless spectators. 

The morning was further punctuated by the finding of another invalid by BCW. Racing across the grass, with only one wing to show for it. BCW came to the rescue and before you could buzz, this biggerLittleBumble was in a care ward of its own too. Same protocol: isolation and quarantine to begin with, for the safey of all concerned. Now, biggerLittleBumble is more energetic, but again is doomed never to fly. All that energy has to be worked off somehow - racing round the box is one way; perhaps he's a boy. Boys do that kind of thing. Well, BLB did for sure, and he was a boy.

So, in total we have taken 4 bees into care. BLB passed away soon after and it seems that littleBee might do so soon. But we still have Holly (who is doing amazingly well, almost miraculously so) and biggerLittleBumble. The big question is, can they live together harmoniously? 

What happens after death?

Death is, of course, a natural part of the 'cycle' of life, so there's no getting away from it, even though it's sad when the time comes for our bees to go to the "great big hive in the sky".  

Over the last few weeks we've seen a few deaths and finally today I downloaded some of the footage from the CCTV system. This may seem unduly morbid, but it turns out we were observing some behaviour we hadn't expected. 

A few weeks ago a bee had died and we saw one of its siblings drag it up through the nest layers to a position just under the camera. In the process it seemed to be trying to revive it, even dragging it to the area where the sugar-water wick was. Here's the video:

This seemed to be quite interesting but we thought no more of it until earlier this week we noticed two more stationary bees had appeared in the same location. I went over the CCTV footage to find what had happened and when. What I discovered was that one bee had made its way (very slowly) to the leftmost position on the camera and, sadly, over the course of two hours gradually subsided into stillness.  It seemed probably just a mere coincidence to find two in the same place - especially since we can only see about a sixth of the nest and anything similar could be going on elsewhere.

However, the following dayI was amazed to see the following footage. Very similar to the first with a sibling bee dragging a dead bee to its final resting place. But the intriguing thing is that the location is the same and behaviour ever so similar. In this clip a second bee comes along 5 minutes later and re-arranges things slightly. Here it is:

The whole thing leaves me rather intrigued and wondering whether Bumblebees are known to treat their sick and dead bees in this way? Is this co-incidence or indicative of some kind of organised behaviour? I've not found any other studies yet that answer that question.
