Bee-atrice log hive is on the left.  The inner tube is a draft reducer, not what it looks like, so no snide remarks!

Here's a better shot of Bee-atrice.  The blue tarp in the background is protecting my Tower of Jewels echium plants and artichokes.  I'm hoping they will bloom this time around.

Here’s a better shot of Bee-atrice log hive. The blue tarp in the background is protecting my Tower of Jewels echium plants and artichokes. I’m hoping they will bloom this year because the nectar is so good for the bees and they’ll bloom all summer.

The outside temperature is a frosty 34˙F.  Barely above freezing.  It's no wonder the bees aren't flying today.

While the outside temperature is 35˙F (1.67˙C), the inside is 50˙F (10˙C).  Someone should have cleaned off the cob webs. :)

While the outside temperature is 34˙F (1˙C), the inside is 50˙F (10˙C), which means there is something warm inside.  Someone should have cleaned off the cob webs before he shot the photo. 🙂

Looking through the observation window of Bee-atrice Log Hive reveals lots of honey.  It's such an improvement over last year's status of 'no bees.'

Bee Beard Log hive is doing well with the August 9th swarm that chose to move in.

This hive in the tree swarmed three times during summer.  Two went to Bob and one we transferred into Del's hive.

This hive in the tree swarmed three times during summer. Two went to Bob and one we transferred into Del’s Warre hive below.

Del's hive...the bees came from the green hive in the tree.  After hanging on the pine tree for about three days, I tried to get them to crawl into an inverted swarm catcher scented with lemon grass oil.  No luck.  They finally disappeared.  I thought, "Good, I've got enough hives," only to find them on a branch of this spruce tree.  After they had hung out for at least 6 days, I dropped them into this hive that I had planned to donate to the bee club.

This hive catches the afternoon sun.  Some bees responded to the warmth.

12-31-14...Birdhouse bees.  These bees came from Mary's backyard birdhouse swarm.  When I couldn't get them to move into my new Warre, I 'posted' them here.  Today they are not flying.  Too cold.  You can see frost on the ground in front.

12-31-14…Birdhouse bees. These bees came from Mayor Mary’s backyard birdhouse swarm. When I couldn’t get them to move into my new Warre, I ‘posted’ them here. Today they are not flying. Too cold. You can see frost on the ground in front.  They are in the shade possibly until March.

A closer look at the birdhouse bees shows no bee activity.

A closer look at the birdhouse bees still shows no bee activity.  Guess I’ll have to wait til it warms up.  This hive is in the coldest part of the property.  If they make it, it’ll be because they are strong bees, not because I treated them.

Warre 3...The bees came from Warre 2, around May 10, 2014.  They built up fast but only in the top box.  This 'shelter' leaves something to be desired because every time we get a stiff wind, the sheets of fiberglass blow off.  Thus the reason for the tie down.

So there it is…from three hives a year ago to eight hives this year.  As a third year natural beekeeper, I believe in letting my bees swarm.  I like the article written by British beekeeper John Haverson that “Swarming Bees are Healthy Bees,” so I don’t destroy the queen cells or otherwise try to thwart their natural tendency to swarm.

I go against the recommendations of my local bee association which advises to kill the varroa mites.   I know there are beneficial mites in the hive.  According to long time beekeeper Michael Bush, who wrote “The Practical Beekeeper,” there are over 30 kinds of mites in a typical hive.  If you are killing varroa mites, you are upsetting the ecology of the hive.  I think we should let the bees adapt to living with mites.  Conversely, if we poison the mites, they will eventually build up a resistance at the expense of the bees.

Since we have just started winter, I know that it’s possible that some hives won’t make it, especially if I choose not to feed them.  Those would be the weak hives.  As a fairly new beekeeper I’m constantly questioning whether I’m doing the right thing.  Right now, I am of the mindset that we should not be propping up weak hives because we will be passing on weak genetics.   In my humble opinion when you capture a swarm, you should not kill that queen,  but keep her with the swarm.  She has survived the winter and proven herself.  All my bees have come from swarms.

If my bees can make it to early February, the pussy willows will bloom and weather permitting, nectar and pollen will be available in a critical stage of winter.

Yesterday I noticed honeybees on the gorse blossoms down the road from me.  This was a happy surprise because I don’t usually see bees on gorse blossoms possibly because gorse is harder to work (or so I’m told), but if there’s nothing else available, the bees will be able to get nourishment.  Some individuals around here hate the gorse.  It’s spiny thorns make it impossible to walk near, it grows prolifically, and it’s blamed for burning the town in the big 1936 fire.

March 4th note…  We lost Del’s hive.  It’s not a surprise because it never really built up any ‘honey weight’  pre-winter.  I haven’t taken it apart yet, but when I do, I’ll clean it out, put in observation windows, and donate it back to the bee club.

We lost #3 Warré too.  I took it down last week after I saw robber bees visiting it.  There was still some capped honey in the combs.  About 125 bees were dead on the bottom.  Some of the combs were moldy, so I’m guessing it’s been dead for awhile.  Both hives were weak hives.  While I’m upset at having lost them, I’m thinking that maybe it’s for the best because if the bees can’t survive in our relatively mild winter, maybe they shouldn’t be in the gene pool.  I’m down to six hives now, but the willow tree has been blooming for about three weeks and I can see the bees bringing in orange pollen and that means nectar too!

January 15, 2014  I mentioned the mites this hive and what I was going to do about it..."NOTHING!" (...hoping the bees would know what to do)

January 15, 2014…I noticed a bunch of varroa mites on the bottom board.  What was I going to do about it?  “NOTHING!” (I was hoping the bees would know what to do)

A pile of dead bees that had been dumped out of the hive sometime earlier. This picture was taken from a video I shot in April. The dead bees had been there for a while, but I just couldn't bring myself to photograph them. Too depressing.  It's possible these are all drones with deformed wing virus. I wish I had looked closer and examined them.   I guess I should be happy that the other bees cleaned them out.

April 18, 2014...Box #3 is almost full, I'd better add a 4th box, which is what I did.

April 18, 2014…Box #3 is almost full, I’d better add a 4th box, which is what I did, but that was before the hive started to swarm.  Compare the numbers to May 20th below.

 May 10, 2014...The second swarm that came out of Warre2 in less than two weeks.  I was able to transfer this swarm into a third Warre hive which is doing fine as of this date.

May 10, 2014…The second swarm that came out of Warre2 in less than two weeks. I was able to transfer this swarm into a third Warre hive which is doing fine as of this date. (I just noticed some evidence of DWV bees being evicted in October ’14.)

May 20...Elvis has left the building.  10 days after the second swarm, there's only a few bees left in this the third box.

May 20…Ten days after the second swarm, there’s only a few bees left in this the third box.

June 11...There's been a small group of bees milling around the entrance for weeks.

June 11…There’s been a small group of bees milling around the entrance for weeks.   They don’t seem to have any ambition.  Are they sick?  Maybe.

July 14...Even fewer bees in July.  That means (to me) only one thing.  This hive is going nowhere.  It's all over except for the robbing.

July 14...this is a shot at the middle box showing very few bees.  I'm just waiting for the robbing to start, but after tilting the hive, I realize there's really no honey to rob.

I’ve seen a hive get robbed.  It isn’t pretty.  Once it starts there’s no stopping it.  If it did get robbed, I was planning to take the new comb, freeze it (in case of wax moths), and save for future bait hives.

July and August came and went.  No robbing took place.  A swarm from my log hive presented itself on August 6.  I contemplated combining it with this weak hive, but in the end, that swarm went into Bee Beard log hive of it’s own accord.

September 20...It's possible there are a few more bees showing.

September 20…It’s possible there are a few more bees showing in this top box.

September 20...There are definitely more bees here.

September 20…There are definitely more bees here in the middle box than in the July 14 view.  The hive is building back up.

September 28...the activity around the hive has picked up dramatically.  No more milling about.  Bees are bringing in pollen.

September 28…the activity around the hive has picked up dramatically. No more milling about. Bees are bringing in pollen.

Could this mean the hive has come back?  Could it be that by taking this long brood break, the hive has reduced the varroa mite population naturally and now has started building up it’s numbers again?

 

A look through the observation windows in the back of the hive shows the top box full of empty comb, the middle box being full of bees and comb, and the bottom box with bees and old comb.  The question is…why aren’t the bees working the empty comb in the top box?

A short video showing how fast the honeycomb built up.  Luckily we are having an Indian summer into October.  I’m athinking I won’t have to feed this hive this year as our winters are fairly mild and they have honey stores now.
