Nestbox update - House Wren
After no adult bird came to feed the Wren babies for almost 24 hours, we thought and pondered all day and then took them out the nestbox and brought them to a rehabber (Wild Wings in Hazel Park, they will be happy about donations, it is how they finance their good work). They were nine days old yesterday, not ready to fledge. The day before, the parent had fed them almost every 5 to 10 minutes, then suddenly nothing. The camera takes videos when there is motion or sound. It did not malfunction and I checked the clips as well as the livestream regularly to make sure. I did not want to see the babies die in the box, and I think waiting until the next morning would have sealed their destiny.
No adult bird has returned to the nestbox since. There are strong little birds and I hope they make it. Birds have a rough life, and unfortunately it happens that baby birds lose their parent/s too soon. The good thing is that there are licensed rehabbers who will take them in and care for them until they are ready to fledge.
I hope I get some updates. Be well, Wren babies ❤️
Hatch day for the House Wrens
Yesterday, the House Wren babies have started to hatch. It was interesting to see how the female was taking the egg shells out rather than eating them. But maybe she ate some and threw some out because seven eggs make a lot of egg shell. In the video, you see her tossing out two shells and then you also get a glimpse of the teensy babies. Since they built the whole structure so well, lighting in the box is a bit murky but hopefully things improve a bit once the babies get bigger. I think that so far, all but two eggs have hatched. I am curious to see if the babies will keep them busy enough so that the male loses interest in the BB box. So far, he has not returned with any sticks. The BBs are still around too. They feed their babies from brood 2, and at least the male checks by the box regularly.
Nature can be cruel.
This morning, Dr. Clara laid her third egg and despite the extreme heat, things looked great. However, at 9 pm, a House Wren went into the BB box, pierced all three eggs and threw them out. I am not sure what is going to happen now but I am heartbroken, tbh. This has never happened in the five years I’ve been doing this, and it feels like this season is cursed. I will think of solutions, and the nestbox that is currently occupied by the Wren will be removed once the babies have fledged.

Another nestbox update
Dr. Clara laid her first egg of brood 3 this morning and Lady Corleone is diligently incubating her clutch of seven. Meanwhile the yard is starting to fill up with bird babies, yesterday I saw a Cardi feeding a youngster, they seem to have two. I hope they go and visit the cameras too! The birdbath is a good point to watch right now too, the baby Orioles and Grosbeaks like it a lot. I am still waiting for the second clutch of the Bluebird babies to come to the yard too but that should also soon happen. Things are picking up again finally!
Video: A nestbuilding timelapse
Dr. Clara the Bluebird has been very busy building her nest, a lot faster than the first two. I always find it fascinating to see them build, and the timelapse shows nicely the different sections. First a base, then some framing, then bedding and then embellishments. Since she started in such a hurry I expect her to start laying eggs soon too.
I have been a little behind here with posts lately but there is not a lot happening, and then there was all this rain. The rain has mucked up the pond quite a bit too, so it needed a bit more cleaning than usual but it will be up and running later today. And more photos :) Happy Thursday!
It looks like Dr. Clara and Mandrake
are going for another round. She has started building a nest yesterday, and once again was not too happy with Mandrake trying to help 😄 The House Wren has laid a total of seven eggs and is currently incubating. We had some nasty weather here recently and I am happy to see the nestboxes withstood the storms just fine. I hope the same goes for the bird babies in the area. I am expecting to see more any day now.
Wren update
While the Bluebird babies have grown and started to fledge, the House Wren has gotten comfy in her nest and enlarged her clutch. This morning, she laid egg number six. It is possible that she does another one tomorrow, but then she should be done.
Video: Fledge day!
Four of the Bluebird babies left the nest early this morning. There is a runt, and he / she is still in the box, all dry with torrential rain outside. It was cool to properly see and hear the process of them getting ready to leave, it’s gotta be such a big decision for them. They do a back and forth call with the parents, and once they feel save enough, they just go In the second video you can hear the parent answering outside a bit too. The third video was a cute scene from the other morning. Mom came to check on the babies, and the sun made her shadow appear on the wall like a little movie.
Update - all five babies have fledged now. That a big day for them! The last one left the box at around 2 pm during heavy rain. Such a little trooper.
Things have been busy
for me work-wise lately, so I wasn’t able to dedicate as much time to bird photos as I wanted, but I have put the cameras out every day and curated the harvest. But there is also a relative calm in the backyard. The Wren has now five eggs, which is wonderful. I can hear baby Blue Jays and mostly baby Grosbeaks but they are rare to see still. The Bluebird babies are ready to go and I think they will fledge tomorrow. The weather forecast is a bit nasty, but I think they are so sick of the nest they will go for it. There will be photos tomorrow / Friday. Good night!
A happy Father's Day
to all the fathers and father figures out there. Sir Corleone, the House Wren, has now good chances to be one soon too. Lady Corleone has graced the nest with a first egg this morning. She will now lay one per day until her clutch is complete. As you can see, they have been obstructing the view a bit but things are always in motion, and maybe it improves over time. Observations so far - they are still vocal even if they have mated now, and one of them spends the night in / at the box even if they are not incubating yet.
The Robins
are having more than one brood per season, and since I have seen them gathering more nesting material, I put up the little bowl with mud and leaves and grass up again to help them out a bit. This one apparently took a good portion, and then came straight to the feeder. Happy Friday!
Video: Dr. Clara and Mandrake
both take turns to bring caterpillars, flies, moths, yellow jackets and spiders to their young. It is amazing what these tiny shrimp can swallow, but often, they need to empty themselves right away too. Which is what you see here. Mom takes the white fecal sac, the "diaper", and either eats it or discards it away from the nest.
Video: The House Wren has been diligently constructing the nest,
and I am so intrigued by witnessing the whole process. He builds something like a little fortress, with ladders going all the way down to the nest. Here, you can see him adding spider egg sacs. There are several theories about why they do it, one is that the spiders will help with mite control, another that they are purely ornamental. I have decided to call him Sir Corleone because "Lion Heart", "cor leonis" is one of the names that has been attributed to these fierce tiny birds in the past. He is a strong singer, and I am excited to see if he can attract a female.
Nestbox update: Bluebirds
I have enjoyed peeking into the nestbox via camera all week, and am happy to report that everything looks fine with these Bluebird babies. The fifth egg hatched one day later than the first four, but all babies look healthy and have been growing well. The summer weather is a two-sided coin, I am always a bit nervous about them getting too hot, but I think it is also giving Dr. Clara a break because she does not have to sit in the box the whole time. When she does, Mandrake often comes to bring food. There are plenty of insects in our yard so I am fairly sure that this brood has a good start in life. I will post some more videos later this weekend.
Videos: Finally!
It’s hatch day for the Bluebirds 🥰 Very early in the morning, Dr. Clara and Mandrake's babies started to hatch. In the first video, you can see her helping and also eating the eggshell. In the second video, you can see Mandrake coming in, making a call and bringing food. The vocal interactions during incubation have been sparse, but now there is communication each time food is brought. Four have hatched, one egg is left. It is swampy outside today, so they should feel nice and comfy.
Video: House Wren cleaning up and starting nest
The "Starling-proof" Flicker box that we built and hung did not attract the species it was designed for, so I decided to change things up a bit and hung the Troyer that I built in that spot. I saw a Downy checking it out and packed it tightly with wood shavings in case she wanted to excavate a roosting spot. Then, a differently looking beak showed up and started to get to work. A House Wren! It started taking the shavings out, one by one, hyperactively, and now has begun to bring sticks in. Wrens have nested in that spot before and I am happy to see them back. I don't want to tinker with the door to restrict access to larger species now, so we will have to see if the Troyer style works out. At least with the camera I can monitor precisely.
Bluebird nest #2 - 2021
Dr. Clara and Mandrake's second brood is underway. I am very excited about this and hope to get some cool videos with the new cam. The sparrow spooker is also installed now and Dr. Clara accepted it right away. If you want to know what a sparrow spooker is and how you can help Bluebirds and other native cavity nesting birds succeed, I recommend visiting sialis.org, a website that covers nearly every aspect of the topic. I will collect photos of the egg laying here.
May 26, 2021: Dr. Clara spent another night in the box. We finally got some rain last night, and it stormed for quite a bit. Temperatures have dropped a lot too, and today it is a lot more bearable outside. she is in the box a lot but I am not entirely sure if she is already starting to incubate or if she will lay another egg tomorrow. I guess we wil lsee then.
May 25, 2021: Like clockwork, Dr. Clara laid another egg this morning. She also spent most of the night in the nestbox which I found a bit unusual. Now it will be interesting to see how many more eggs she will lay. I had a clutch of six one year, and this is the “main season” brood with the best amount of bugs around and the mildest temperatures.
May 24, 2021: On time, egg three was laid this morning. Temperatures have fallen after a hot couple of days, and it is a bit rainy out. Dr. Clara has not spent a lot of time in the box yesterday but I was happy to see her coming right back this morning.
May 23, 2021: The second egg is laid, at around the same time, between 8:30 and 9 AM. Temperatures outside are very mild in the morning and turn hot in the afternoon, so the female is not visiting a lot. Both adults and the babies are hanging around.
May 22, 2021: Dr. Clara lays the first egg early in the morning.
Video: I have always loved
the song of the Bluebird but it is awesome to hear them up close, communicating around the nest. Here, the male, Mandrake, goes in to "rearrange the furniture" while the female, Dr. Clara, is waiting outside. It appears that she soon has enough of him doing that, and she demands that he come out 😊
In the second video, he is showing off his vocal skills when he again went into the box to “fix things”. At the end, you can hear a little warning call that they do when they feel that they need to take cover.
And just like that,
the second nesting is underway. I have said it yesterday already but i am over the moon that they are back and building. Here, you can see Dr. Clara bring in pine needles and then spreading her wings and pushing with her chest to form the nest cup.
Dr. Clara and Mandrake
and me have had a rough couple of days. After they sucessfully fledged four babies, the couple disappeared as usual to show the babies the world. They did come back occasionally to feed and check on the box. One day, however, a House Sparrow took a liking to the box. This was a first, it has never happened in five years. I use a Gilbertson box, which they usually do not like, with fishing line around the entrance, and the sparrow spooker also was still up. Shooing and spooking the sparrow did not deter him and his lady. One day, I was not home for one hour, and the sparrows had started a nest in the Bluebird box. House sparrows are invasive to the US and can have negative effects on the breeding success of native species like the Bluebirds. I will not let them nest in my boxes.
Eventually, I took the Gilbertson down. After one day, the sparrows moved on. I was very upset about this whole situation and decided to be proactive. I researched and built another box, a slotted style called Troyer. The slot and its relatively small volume are something that HOSP are usually not fond of. The slot lets in lots of light, and they like it dark and deep. The slot opening also enables the female to escape if a House sparrow should go in there to attack her. I also updated the camera in the same step. Now the BBs have brought their baby (it looks like possibly one one of the four has survived this far) to the backyard yesterday, and they have been checking out the new box already too. I hope this all works out, I did not like changing things like that mid-season but I did not want to keep the old box up that the sparrows ended up liking. This is a weird spring.
