I will update this post continually (instead of writing multiple posts that could easily take over this blog) as I explore the capabilities of the Flir One infrared camera device. The updates will appear in descending order. The latest update was posted on December 19th, 2016.
DECEMBER 19, 2016: I know people who are getting much better results with their Flir One than I am. I realize my long rambling post here probably isn’t providing the best information because I’ve more or less taken the point-and-shoot approach. I want to turn this thing on, take a thermal image and immediately see something that’s useful — without having to modify the image later on using another application or program, because I don’t have time for anything else. Easily 95% of the images I get following that approach don’t show me anything that helps me. For people like me who may have day jobs, family responsibilities or other activities that don’t allow them much time to fiddle with something like this, I’m not sure I can recommend the Flir One. It’s too expensive and time-consuming. I’m not saying it doesn’t work, but in my experience so far, it’s definitely not something that produces great results just by plugging it in. It takes time and perhaps some knowledge of thermal imaging to get the most out of it.
DECEMBER 07, 2016: I took the following thermal images with my Flir One today. The automatic settings didn’t give me much to work with, so, again, I tried to adjust the settings on the fly and got various results. Using the Flir Tools app or the software on my computer would probably produce better images, but I don’t have time for that. If I can’t get a half-decent image by using the Flir One as I would my cell phone camera, then it could easily become yet another beekeeping chore that takes up more of my time. I’d rather instant results, not something that requires additional processing afterwards. So I’m aiming for simplicity at the moment even if it means I’m not utilizing the Flir One to its full potential. So… It was about -10°C when I took these pics, and no wind. It felt icy cold. Everything was frozen.
It was zero degree Celsius today (also known as the temperature at which water freezes). It was also extremely damp and miserable. Not a bad day to see if visual inspections of the clusters match the thermal images from my Flir One for Android camera device. Not a bad day to make some pre-winter adjustments to some of my hives too.
Hive #1. Other than dropping in some sugar over the top bars in a week or two, and maybe wrapping the hive, Hive #1 is just the way I like it.
A word about that top cover. Yup, it’s a piece of plywood I found in the corner of my shed. I put something heavy on top to keep it in place, but that’s it. I’ve had it on the hive for several months now, always meaning to replace it with a real top cover but never getting around to it. I may leave it on the hive all winter. Why not? The inside of the hive is warm and dry. Whether it’s a commercially made telescoping top cover dipped in wax with a metal cover, or a dirty piece of scrap plywood taken from a junk heap, it doesn’t seem to make any difference to the bees.
Here are some quick snapshots I took this morning of my hives using an infrared camera device attached to my cell phone. It doesn’t provide the most helpful readings at the moment, probably because it’s not cold enough outside to highlight the heat that’s radiating from the insides of the hives. I also used the default settings on the device. More precise calibrations might provide me with better images. But for now, here are my best guesses about what’s happening inside my hives according to these infrared images.
Here’s a low-rez infrared video of one of my beehives recorded through my “Flir One for Android” device connected to my Samsung Galaxy s7 smartphone.
Like most electronic beekeeping gadgets, it’s not for beekeepers on a budget and it isn’t really necessary. This is only a test recording. I’ll post more about it probably sometime in the winter, if I find a practical use for it.
All the photos and videos from the Flir One are low resolution, but it doesn’t matter.
People who idealize and romanticize beekeeping — I would guess that’s 99% of all people who have ever gotten into beekeeping, including me — are in for a big wake up call after they kill their first colony. Sometimes colonies die of natural causes, but whatever the reason, a hard fact of beekeeping is that bad things happen and colonies die. If honey bee colonies can die in nature even under ideal circumstances, they can die in a beeyard too.
My ragged queen bee (and her potential colony) finally died yesterday after what might be called a prolonged illness. And I’m okay with it. Honestly, I barely gave it a thought. Losing my first colony a few years back was a hard hit, especially since it was my fault and the colony was healthy and huge going into winter. The honeymoon phase of my beekeeping life died right there on the carpet. While it was certainly discouraging and sad at the time, I’ve come to accept that these things will happen and when they do, I give myself a moment (and curse to myself if no one is there) and move on. That being said, here’s the lowdown on what I found five days after I installed my ragged queen into a new hive — and after two weeks of keeping her alive with a light bulb inside a nuc box. (For anyone late to the party, all the details of this desperate tale are preserved through a unique label I just created called Ragged Queen.) So… …
I carelessly caused one of my colonies to slowly starve this winter. The cluster was about the size of my fist, maybe a little larger. Ten days ago while I was getting ready to dismantle the hive and cut my loses, I found the queen still alive. I knew the cluster was too small to keep her warm enough to survive another month of cold Newfoundland weather, so I quickly jury-rigged a nuc box with a light bulb for heat, put the bees in that and hoped for the best. The bright light bulb killed off about a hundred bees like moths to a flame. I eventually replaced it with a red light bulb. Today I put a cage around the light bulb (in a different box) for extra safety and it looks like this:
Then I put the bees in like this (that’s a dummy board on the outer edge of the frames to prevent the comb from melting):
I looked over the bees during the transfer and couldn’t find the queen. There’s a chance she’s in there, but it doesn’t look good. I’ve done all I can. The bees won’t freeze with that light bulb. They have an exit hole close by for cleansing flights and three frames of honey. Now all I can do is wait.
Let’s assume this is a lost cause…
I think I could have saved the bees if I’d discovered them starving at least a week or two earlier. The cluster would have been larger. They would have had a better chance. Not using a caged red light bulb from the start probably didn’t help, but it was the best I could do on the spot with the materials I had available. I learned about a beekeeper who uses a red light to keep his bees warm all winter. I would never do that, but I do plan to keep at least one heated nuc on standby for next winter just in case (and I’d probably use a ceramic light bulb instead so the bees can’t even see the glowing filament). I’ve also decided to pick up a thermal imaging device for my smart phone. I already have a stethoscope, which has been helpful though it’s not what I’d call a precision instrument. Cheap endoscopes are also available, though I’ve heard people having mixed results with them. But I’m pretty sure if I’d been able to take an infrared photo of my starving hive throughout the winter, I would have seen the cluster begin to shrink as it was cut off from its honey supply and I would have been able to move honey close to the brood nest and save the bees.
APRIL 6, 2016: Even the caged light bulb attracted and killed some bees. If I had to do it again, I’d wrap the cage with heavy duty tinfoil, or perhaps even better, I’d use a large tin can instead of a cage and poke some tiny heat holes throughout it. Judging from what I’ve seen so far, I’d say a 60-watt light bulb, even behind a big tin can, would provide enough heat to keep the cluster and the queen alive.
I’ve been asked many times now what I think of BroodMinder, a new device that monitors the temperature and humidity of a beehive through use of a cell phone app and sells for sixty bucks American. I haven’t written about it before because I don’t have much to say about it. But here’s what I have to say for anyone who’s dying to know.
I think the BroodMinder is really neat. (Please feel free to quote me on that.) I wouldn’t hesitate to install the BroodMinder device on one or all of my hives. I would love to add temperature and humidity readings to the observational data on my hives. The BroodMinder readings might not make any difference to how I keep my bees in the winter (or the summer), but more knowledge about what’s going on inside the hive is usually a good thing (usually). So yeah, it sounds great. I’m all for it.
But it’s not going to happen for me because I don’t want to spend almost another $80 in Canadian cash on each of my hives if I don’t have to. That’s about $400 to cover all five of my hives (and I expect to max out at about ten hives in a year or two). Even $80 for one BroodMinder is too much for something that isn’t essential to my beekeeping. So although I like BroodMinder and I support it in theory and would love to try it out in the real world, it’s a pass for me.
P.S.: I’m well aware of the perception that beekeeping as a hobby is, in essence, a money pit, and I have to confess a bias towards beekeeping practices that save money, not ones that cost more money. Not that the BroodMinder is overpriced for what it does, and I admire the efforts of the people behind it, but it’s one of many items that most hobbyist beekeepers on a budget (like me) probably don’t need.
I often use a cheap stethoscope to monitor my honey bees in the winter when they’re still clustering below the top bars and out of sight. It’s the least disruptive method I have for checking on the bees.
It took some practice, but I can tell how deep and how large the cluster is by listening through the hive with the stethoscope. Most of the time, though, I’m just checking that the bees are still alive. That’s usually good enough for me.
Sticking my ear against the hive works too, but it’s not as dignified as walking around with a stethoscope.
FEBRUARY 20, 2016: I have to say I continue to be impressed with the $7 stethoscope I bought on Amazon. I listened again to my bees today and could hear a lively buzz of bees in every hive. It takes a bit of imagination to interpret how the bees are doing from the often distant-sounding hum heard through the stethoscope, but at least I can tell they’re still hanging in there.
