I’ve posted several photos and some videos of honey bees fanning over the years. Let’s add this cell phone video from yesterday to the list:
The bees clamp on tight to a spot outside the hive entrance and beat their wings with everything they’ve got to create an air current inside the hive that helps evaporate nectar into honey and regulates the temperature of the brood nest.
If I wasn’t home sick with the flu, I’d be out with my hives adding ventilation rims, screened inner covers, screened bottom boards, slatted racks, dummy boards and whatever else I could think of to help my bees cool off on a day like day — or I should say a summer like the one we’ve had since the first week of June with record-breaking consecutive days of sunshine and above-seasonal temperatures. If I took a look at my country hives today, I’m confident I’d see considerably more bearding than I did back in August 2011 when I took this photo:
I wouldn’t be surprised if the combs are melting inside the hives on a day like today, especially inside the dark green hives that are absorbing the most sunlight. I gotta get me some white paint.
One of our honey bee colonies swarmed into a tree last week. We caught it and put it in a new hive with a small frame feeder and three frames of empty drawn comb so the queen could start laying right away. We checked on it yesterday and here’s a video that shows what we found (it’s doing well):
It’s not the greatest video, but it shows how things are working out for us since we moved the hives from our backyard to a place in the country. I won’t say exactly where we moved the hives, but anyone familiar with farms around St. John’s probably won’t have a hard time guessing correctly.
A couple notes about the video: 1) I got lazy with making my improvised ventilated inner covers. I came up with an equally effective but much easier to make version of the same thing at the 3:19 mark in the video. We haven’t tested it much yet, but I’ll write up a more detailed post for it later if it works. 2) The hived swarm probably doesn’t need two deeps just yet (and probably doesn’t need the extra ventilation), but swarms are known for building up fast. We gave them the extra hive box in case we can’t make it out next week. We’ll keep feeding the hive now just like we would with a nuc.

3:13pm. May 22, 2012. St. John’s, Newfoundland. Temperature: 31°C. Check it out:
I had to post the photo because otherwise no one would ever believe me.
Updates: It went up to 31.1°C while I was writing this. 3:56pm update: 31.6°C. 4:25pm update: 31.9°C. 6:40pm update: It’s 25°C. The digital thermometer may have reached 32°C around 5 o’clock, but I was too busy painting hive boxes too check. The bees were out in full force from 10am to just about now. I added ventilation rims to all the hives and what passes for a screened inner cover to Hive #1, our three-deep hive that’s literally busting through the roof with bees. Today was a good day to be a honey bee in St. John’s.
It was warm enough today (1°C / 34°F) to take a peek inside our four hives and add some pollen patties. I didn’t have to top up the dry sugar that was added 46 days ago. The bees in the foundationless hive are low on honey, as I suspected, and have eaten through the most sugar, but they have enough to keep them going for a while. The bees in the conventional hives have eaten some of their sugar, but I still think they would have been fine without it. I could see several frames full of honey in each of the hives. The bees in the conventional hives were clustering above the top bars by the end of December, but a lack of honey doesn’t seem to be the reason. Okay, then, here’s how it played out in video form. First, a short version in HD that cuts to the chase.

We finally got around to wrapping our hives for the winter. Here’s another how-to video narrated by me with a sore throat.
I thought about using corrugated plastic as a type of winter wrap, but I didn’t have time to mess with that, so I stuck with following the traditional roofing felt wrap method. We don’t plan to touch the hives again until late January or early February when we might have to feed them candy cakes and pollen patties. See Wrapping Hives for Winter and Winter Preparations – Part 1 for more info.

It went up to a stifling 11°C yesterday (52°F), so I took the opportunity to insulate our hives for winter and staple on some mouse-proofing mesh. This is as simple as it gets.
|Hard insulation installed over winter-positioned inner covers (minus the top covers.)|
The inner covers are in the winter position (with the convex side up, a.k.a. the flat side, which is misleading because both sides are flat, but basically you know it’s the winter position because it gives the bees more head space than when the “flat” side is down; anyway…). A piece of hard insulation is installed flat against the top of the inner cover. It covers the hole in the inner cover and you don’t have to make a tunnel for the bees through the insulation or anything because the bees have no problem getting outside through the upper entrance notch in the inner cover. Some beekeepers put duct tape over the inner cover hole so the bees can’t eat away at the insulation, but I didn’t use duct tape last winter and the bees didn’t get hungry for the insulation once. And that’s all there is to it. (See Making Insulated Inner Hive Covers for more info.) Just put the top covers on once the bees get out of the way, and you’re done.
The only problem with this method of insulation is that it doesn’t leave much space under the inner cover for feeding the bees candy cakes or pollen patties in late winter. To make that extra space, all you have to do is install a two or three inch rim (or an eke) under the inner cover. That’s what I plan to do. There are more than a few ways to insulate the hives for winter (moisture quilts, etc.) — and more importantly, to prevent condensation from building up inside the hives. This is just one of them. Along with wrapping the hives, it worked perfectly for us last winter. There are also plenty ways to feed the bees over winter (candy boards, etc.), but I can only talk from my own experience. Okay, then, let’s take a closer look at what I did yesterday…

Here’s a short uneventful video I took of the hives today where I mistakenly refer to Hive #2 as Hive #1. (I need to paint numbers on the damn things.)
And now here’s a quick review of the 4 hives in our backyard as they stand today:

That’s right. I made a screened entrance reducer and it looks like this:
The wasps or yellow jackets hanging around our hives have become intense in the past few days. They’re constantly trying to get into the hives. I’ve added entrance reducers, but the entrance reducers also reduce the air flow (the hives don’t have screened bottom boards). The humidity builds up fast inside the young 2-deep hives when the sun comes out. So I made this screened entrance reducer from scrap wood, a piece of mosquito mesh, some duct tape and a piece of corrugated plastic from an old campaign sign I stole from a local politician who didn’t get re-elected. It’s just a prototype, but as you can see in the photo, the entrance has been reduced to about one bee-length while the bottom entrance space is still fully ventilated. Theoretically, it seems like a good idea. We’ll see how it works out.
UPDATE (Sept. 26/11): The screened entrance reducer works fine. Some of the bees get confused by the screen and it takes them a little longer to find their way back into the hive, but I doubt it holds them up any more than a solid entrance redcuer would. The general concept works. Now I just need devise as easier way to make them.
I got creative this summer and built a solid bottom board and a screened bottom board from scrap wood in my shed. I can’t continue to use either of them for long because the wood I used is old and half rotted and I’m afraid the boards will collapse under the weight of the hives during the winter, and around here that means damp and soggy, great conditions for softening up old plywood. So I went ahead and got more creative with my limited carpentry skills and woefully inadequate tools (or maybe it’s the other way around), and I built a new and improved sturdy bottom board that is both screened and solid. I won’t have a chance to put it into action this year, but I’ll show it off anyway. Here it is as a screened bottom board:
