In 20 nest boxes…
11 Nesting pairs (includes second brood with two pair)
50 eggs produced (includes three non-viable/destroyed)
42 hatchlings
38 fledglingsThings seem to be slowing down. Our “drought” is over but we still need lots of rain. Drought is a relative term and is nothing like other parts of the US and Canada are experiencing.
I attempted to raise mealworms to feed the birds but have decided that making sure they have a nearby water source is more important. Now I just need to know what to do with thousands of Darkling Beetles. The bluebirds find their way to food even in our drought. I’ve read that feeding dried mealworms is not a good idea for hatchlings. The author’s reasoning was that the moisture in the bugs is the hatchlings only source of hydration until they fledge. Dried mealworms do not provide that very important hydration.
The number of hatchlings and fledglings I report are based on laid eggs. I monitor the nests regularly but I don’t open the boxes and count and I’m not there to watch the fledgling process. It is difficult to count hatchlings when they are laying on top of one another. I refuse to open the nest boxes during laying, incubation and raising of the hatchlings. I saw a video of an expert holding a nest with four eggs he removed from a box. Then holding another nest with two hatchlings and a couple eggs. One of the hatchlings rolled out of the nest and almost fell to the ground before he picked it up and replaced it in the nest. He rambled on about his method not bothering the parents. Opening a box and removing the nest is ALMOST never necessary. But what do I know as a rookie bluebird landlord.
I use a wifi endoscope that transmits a video image to my phone (and can take stills). I peek in, try to do an assessment of the nest and move on in less than three seconds if eggs, hatchlings or an adult is present. If none of them are in the box I may take a few more seconds to peek to check nest materials, wasp nests, etc.
Done with my lecture. If you are opening and handling babies please reconsider your methods.

As long as we are on the Wren subject I will say the little jerks are entertaining to watch. I think I’ve frustrated my Wren enough with dumping their stick. This afternoon they started hauling sticks in the box they were in the last month. At one point he had a Y shaped stick trying to put it through a very small entrance. I think it is the minimum size for a Wren. For close to 15 minutes he tried every which way to get the whole stick inside. He was noticeably frustrated making interesting noises when the stick would fall on the ground. He never did get it completely inside. Right now I’m debating whether to help him out by snapping the one leg off that’s sticking out of the hole. Little stinker doesn’t deserve my help but I’m probably going to weaken!

I’m amazed with the differences from one Bluebird pair to another. One pair’s babies, my earliest nest on a nearby trail, fledged. I cleaned the box out the next day. A day later I find an almost fully built nest and the next day an egg. There were three eggs last I checked. Another pair, which I never saw or heard, built a nice nest, laid three eggs and then the eggs were abandoned. I don’t know what happened. Maybe the adults succumbed to predators. And then there is the nestbox in my yard. The BB pair laid six eggs. Successfully hatched all six and they fledged on Sunday. I cleaned out the box Monday morning and haven’t seen or heard them in the yard since. Stinkin wren is taking over the box which kinda ticks me off because their babies fledged a couple days before the blues from a box across the yard. That box is clean and ready for occupancy but they decided to ignore it and build in the blues nestbox.
I’m just happy that I’ve had the success I have had. It really helped me get through a very long winter/spring.

Same here. My yard’s BB little guys fledged on Sunday. I cleaned out the box and the stinkin wren keeps piling sticks inside. I’m about to give up and let them have it since I don’t see or hear the Blues in the yard at all. Keeping my fingers crossed. One more day of stick dumping then I’m out of town for five days. Upon return I expect eggs to appear so I’ll settle with the little stinkers.

This is probably too late for a solution for you but my father in law says in the spring that wrens arrive before blues. In order to save a nest box from those cute little stinkin wrens he puts tape on the entrance hole until he is sure Blues have arrived.
I just tried this with a box I cleaned out yesterday after the blues had their first batch of babies. A Wren was starting to bring sticks into the box so I taped the hole to discourage him. I have a dedicated Wren box on the other side of the yard that the Wrens just fledged from and I cleaned out. Hoping this works. Unfortunately with an egg present discouragement is not the proper solution.

Hi Judy, those numbers don’t include three pairs of Tree Swallows. So thirteen occupied boxes. I have other boxes not on the list and include a pair of House Wrens (7 babies fledged yesterday) and a beautiful pair of Great Crested Flycatchers which fledged five babies the other day. The Wrens and Flycatchers are not in BB nest boxes.
Really enjoying this effort and all the posts here on BBnut.

July 2…
20 Nest boxes
10 pair nesting (1 second brood)
44 eggs (incl hatchlings, 3 abandoned)
38 hatchlings
20 fledglingsGood success. Three eggs abandoned in one nest box. Otherwise I am assuming eggs became hatchlings and eventually fledglings. I don’t think that is a poor assumption considering I don’t open the boxes and do a head count once hatched, though I admit that the fledgling number may be higher than reality.

First pair I had nesting had five babies fledged sometime between June 20 and 25. I cleaned out the box and the next day there was a full nest in it. I had to look back at my spreadsheet to see if I was confused (so many nest boxes). Nope, I definitely cleaned it out about 36 hours ago. One day later there is an egg and this morning three eggs. Those little buggers work fast and are keeping me on my toes.Another box the last time I checked were five hatchlings. This morning it’s empty. Cleaned that box and hoping for a quick return.
The only negative outcome so far is a box I installed on May 26th. On June 15th and June 25 there were three eggs and no sign of BBs. The next day one egg appeared to have been hatched but whatever that pile of stuff inside it definitely wasn’t a baby bird. I cleaned out that box the next day. I’m hoping they return. I don’t know if it was abandoned or what. Normally I don’t go ten days between checking but I was out of town for a week.
Having a dozen and a half nest boxes to monitor is proving to be challenging. But I am probably over monitoring due to beginners excitement. I hope next season I can delegate some of them to someone else. I’ve had many inquiries about who is putting up all these boxes!

June 25
9 pair nesting
38 eggs (incl hatchlings)
21 hatchlings
5 fledglingsSo I’m new to this and will appreciate feedback if there are any experienced bluebirders that do monitoring of similar numbers of nest boxes. My earliest nesting pair had five hatchlings. After returning from a trip the nest box is empty with no sign of hatchlings. I do hear BBs singing in the trees nearby. I decided to clean out the nest even though I don’t know when the birds fledged. The first sign of incubation was 5-28. So it’s been about 29 days since incubation started.
I want to report to BRAW at the end of the season with numbers as accurate as possible. I am assuming all five hatchlings fledged even though I don’t have evidence of that. And I also assume that when I peek into a nestbox with hatchlings and they are sitting on top of each other I all the eggs hatched. Are any of these assumptions problematic?
Thanks,
Tim

9 pair nesting
35 eggs (incl hatchlings)
10 hatchlings
0 fledglingsOnly monitored five boxes today. I’ll check the others tomorrow and update numbers. Then I’m out of town for a week so no updates until at least 6-25. It’s getting crazy out there!

Haha. Thanks for the encouragement.
I’ve pointed out snakes on the trail to Rosie but she isn’t interested. Now if chipies and squirrels were a danger to bluebirds then she’s a champion!
U am really enjoying this. Though I’ve found that the number of nest boxes I’m monitoring is a challenge. I’m hoping my library will have a bluebird seminar next winter and I can find some folks to delegate some of that work.

I’m going out on a limb and saying this has been a big success for this rookie bluebird landlord who less than a month ago didn’t know if I was going to get any nesting pairs. Keeping my fingers crossed that hatchlings and fledglings are close to 100%.
One thing I didn’t realize is how much this hobby has consumed me. My daily dog walks have turned into daily bluebird trail dog walks. The birds definitely notice Rosie but don’t seem to be too concerned. I do have to apologize to my Yooper neighbors. I may have put a small dent in bluebirds migrating through to the UP : )

My method is probably not for most people. I am a member of a teardrop camper forum and they host their own photos on the site. It creates a “Image BBCode” (I don’t know how that is different from JPEG). Anyway, if you are a member of a forum that uses that format when you post photos there you may be able to copy and paste here.
I try not to overdo posting bluebird related photos there when they have nothing to do with campers. Maybe bluebirdnut could look into offering that option, but, I suspect it is a costly upgrade.

I’m lucky. I haven’t seen a House Sparrow in my community yet. I know they are here but not bothering my nest boxes.
About six miles away (as the bluebird flies) there is a Home Depot that they seem to prefer. When I go there I hear them under the canopies and inside they are chattering all day.
