We’ve lived in our house for 34 years now. In all that time, I’ve only seen Eastern Bluebirds once or twice. Even then, they’ve never stayed long . . . until now. For the past few weeks, two male and one female bluebird pop up at the feeders periodically. Most days I see them for at least a few minutes. I’m trying to encourage them to stay. 

This post will be a bit different than my usual posts. Instead of sharing everything I’ve learned afterwards, I’m going to offer a real time journal along the way. Hopefully I’ll be able to report that I’ve succeeded in enticing a pair to stay and nest in the yard. I hope you’ll take the journey with me.

A Yard Appealing to Bluebirds

I have to say that I’ve never tried to lure in bluebirds before. There didn’t seem to be much point. Our yard is a one acre wooded suburban lot in central Maryland. It’s not forest, but it does have a lot of mature trees and not much wide open grass.

If you’ve ever watched bluebirds, you know they like to sit maybe five feet or more off the ground out in an open area. From there they fly down to the grass to nab insects to eat. So you’ll usually see them in large fields or places with a lot of open lawn. That doesn’t describe our property . . . BUT.

In January, a very large pine tree fell down in our back yard. Its loss has made the back yard much more open. I think that is why bluebirds have been willing to spend more time in our yard than they have in the past. So maybe there is a silver lining to the loss of the tree.

Mid-February: Bluebirds Arrive

Two males and one female Bluebird are eating suet from the back suet feeders. I’ve never seen this in our yard before. The feeders are the upside down type that requires a bird to cling to the bottom surface. Bluebirds can’t spend a long time dangling from them. But they repeatedly nibble at it and sit on the shepherd’s hooks they hang from.

A few days later, I again saw two males and one female at the suet feeders. They were at the feeders at both the front and back yards this time. Now they are also eating sunflower hearts from the back Squirrel Buster Plus feeder and drinking water from the heated birdbaths.

And a day or two later, the same three (apparently) are in the yard again, eating suet and sunflower hearts. This time they are also eating some dried mealworms in one of the hanging feeders.

They are becoming regulars, showing up at least once most days. They don’t stay for more than fifteen or twenty minutes. Typically they will go for some suet, sunflower hearts and dried mealworms and a sip from the birdbath. Sometimes they sit under the suet feeders when woodpeckers or other birds are on them so that they can pick up fallen bits of suet. This is a strategy I’ve seen others bird use in the past.

February 20: Bluebirds in the Snow

Here in Maryland we had a decent amount of snow on February 20th. A male and female bluebird spent quite a bit of time on the back suet feeders. They are about twenty-five feet from our back door.

I sat on the back step and took pictures. They were definitely aware of me but it didn’t seem to bother them that I was sitting there.

February 27: Buying a Bluebird Box

I’ve decided to try to entice the bluebirds to stay. Researching Eastern Bluebirds, I learn that they traditionally use nesting cavities in trees but cannot excavate them themselves. So they often use those originally carved out by another species.

With more people around and fewer old and holey trees in the right settings, this type of cavity has become less easy to find. So people are encouraged to put up bluebird nest boxes if they have the right type of area for them. I’m going to give it a try.

I went to my local birding store (Mother Nature’s in Columbia MD) and asked for advice. They had a variety of nest boxes and were able to point me to several that would work. (2024 Note: Mother Nature’s has just converted to a Wild Birds Unlimited Store.)

You want one that has an entrance hole that is 1 ½ ” in diameter. This hole needs to be big enough to allow bluebirds access but not so big that European Starlings or other large birds can get into it. The box I picked has copper around the access hole. This prevents it from be enlarged by another bird or other predator.

The nest box I chose is a “wooden nest-roosting box” from Birds Choice. Quite a few of the feeders in my yard are from Birds Choice (although they are made of recycled materials.) This box is made of red cedar which should last quite a long time.

The entrance hole is at the top of the front panel. In the winter, you can optionally unscrew the box and flip the front panel around. This puts the entrance hole at the bottom so that it can be used for roosting.

There are also two dowels included that can be used in this roosting position. They are not to be used when it is set up to be a nest box. It has an “overhang roof, vents and drainage holes to keep the nest dry and cool.”

There is a little thin metal piece on the bottom right front. Turning it allows you to lift open the front panel to check on things in the box or so you can clean out the box after nesting is completed. Attached to the inside front panel is a bit of metal screen. This allows little birds to more easily climb out when they are ready.

March 2: Where to Put the Box?

I again did some research to decide where to put up the box. Most bluebird information sites online tell you to put the box so that it doesn’t face into prevailing winds. You should put it in an open area and not among trees. But it should be close enough to a perch to give nestlings a place to land when they fly out.

I was also interested in how far a box would need to be away from bird feeders. I have a lot of feeders and assumed that it shouldn’t be right near them, but needed distances.

According to the Michigan Bluebird Society, nest boxes should be at least fifty feet from feeders and the house. So I found a spot in the back yard near our back neighbor’s chain link fence that is fifty feet from the closet feeder. It’s probably twice that far to the house.

We oriented the box facing roughly southeast. Our neighbor’s back yard has some large trees but is mostly open grass, so between our yard and their yard. I’m hoping the siting will make them happy.

Mounting Box on a Pole

The box was mounted on a metal nest box pole that I also bought at the store. It is an Erva “Wolf Point Forge” bluebird house pole. Erva is the company that makes the baffles I like so much. The bird feeder poles in my yard are also made by this company. They are sturdy and have held up well for the several years that I’ve been using them.

There were two holes in the pole for mounting the bluebird box using screws. The spacing was a little off for this particular box’s holes though. So Jim drilled a new extra hole in the back of the box to accommodate it. The screws that came with the box were long (probably designed to screw it to a thick fence post. So Jim used some shorter screws he had to mount the box to the pole.

March 3: Bluebirds Find the Box!

I saw one male and one female bluebird at the back yard feeders off and on over several hours. No bird activity around the nest box though. Then suddenly the pair flew over to the nest box and peeked into the entry hole a few times. Yes! They didn’t hang around on the box long but they seem interested.

Our yard still has a lot of old trees that woodpeckers have put holes in so it is totally possible they already have or will choose one of those when they are ready to nest. So this box may wind up being redundant . . . or maybe they will choose it and nest in it. We’ll see.

March 5: Bluebirds Eating Dried Mealworms

I saw one male and one female bluebird at the feeders early this morning. After eating, the male flew over to the nest box, peeked inside and then sat on the box for a few minutes before flying off.

Today is a Feederwatch day for me, so I spent a good bit of time watching birds. I started from the dining room window but then moved to the (very unseasonably cold!) back step. I hoped to get some bluebird pictures.

Dried Mealworms

I’ve been putting out dried mealworms for quite a while now. But mostly I toss a few in the hanging platform feeders and a handful into the nearest brush pile for Carolina Wrens. (Blue Jays and European Starlings also seem to enjoy them.)

For the past few days, I’ve been putting out extra dried mealworms for the bluebirds in the hanging platform feeders. But the European Starlings cleaned them out before the bluebirds had a chance at them this morning. So after a little while, I went out and put some more in those feeders. The bluebirds must have seen me do it. They immediately came back to check it out but couldn’t get close because of the European Starling and Blue Jay activity.

So I went out again. This time I put more mealworms in the hanging feeders and also some in the pole-mounted platform feeder further out in the yard and on the metal platform of the old hopper style feeder right next to it.

The bluebirds quickly reappeared and again were unable to get to the hanging tray feeders. They then moved to the two pole-mounted feeders where I had never put mealworms before. While they happily ate them there, the more dominant birds ate them at the other feeders.

I can never leave things alone though. Still fiddling with things, I later also tried putting some in a ground platform feeder near the hanging feeders. When the male bluebird couldn’t get past the starling in that feeder, he dropped down to eat some of the dried mealworms from this feeder.  (Late in the day, a squirrel got into this ground feeder to eat them. I didn’t know squirrels would eat dried worms!)

It is now mid-afternoon and the bluebird pair have been around all day. A second male also popped up in early afternoon briefly, grabbing some sunflower and then moving on.

The pair seem to be either at the feeders or perched up high in various trees along the fence line. They’ve gotten sunflower hearts a few times but the dried mealworms seem to be the real draw for them. They’ve come back for them repeatedly.

I haven’t seen any more activity at the nest box but they definitely like the food offerings. So they have been sticking around. (The Carolina Wrens seem quite pleased with the extra dried mealworms as well!)

March 6: More Bluebirds Arrive

This morning I put out the last little bit of the dried mealworms. So picked up another bag while I was out running errands. Within five minutes of putting them in the feeders once I got home, five bluebirds popped up to partake of the feast! Today there were three females and two males.

Today is another unusually cold day for this time of year, with temperatures in the twenties. The local birds seem especially hungry. The yard is hopping with twenty-three species and a couple hundred birds. So the bluebirds had some competition for the mealworms. As well as the continually annoying European Starlings who seem to want to eat ALL of everything, there were also two Northern Mockingbirds munching on them.

Although we have mockingbirds in the neighborhood, they don’t usually hang out in our yard very often. They usually only come for a sip of water once in a while. I rarely see one, let alone two, so it was cool having them hang around for hours.

March 14: Starling Problems Continue

The bluebirds continue to be around the yard. They still haven’t claimed the nest box. Myaybe they never will, but either way, I am really enjoying getting to watch them up close. I did add a baffle on the bluebird box pole today to keep out predators just in case.

For the past few days I’ve been seeing two males and two females occasionally during the day. They pop in to see if there are any dried mealworms in the feeder and sometimes grab a sunflower heart or a drink of water.

The European Starlings continue to be a problem with the dried mealworms though. They love them obsessively. Once they find them in a feeder, they are tenacious about sticking around to fill their bellies with them until they are gone. If a bluebird is eating them first, they force her out. If I’m outside, I chase the starling away. The bluebird will usually come right back until the starling gets obnoxious again. But otherwise, the bluebirds are out of luck.

Today I bought a new little weight-activated feeder that I’m trying dried mealworms in. I hope to block out the starlings or at least slow them down.

March 25: Feeder Experimentation

I’m still seeing two or three of the bluebirds every day. I think they are probably nesting elsewhere but it is a joy to have them visit a few times a day.

The feeder I bought to offer dried mealworms is doing pretty well. It doesn’t block the starlings but it does slow them down. I’ve been experimenting with a few tweaks to the feeder to make the ports smaller and deeper to see if I can block them completely.

Switching to a Mealworm Feeder

Several bluebirds are still to be found in the yard (usually at least two males and a female.) I spent a couple weeks trying to tweak the ports on the Squirrel Buster Standard feeder to keep starlings out.

While I could slow them down, I could never exclude them from that feeder. Eventually I started seeing five or more starlings spending way too much time bickering among themselves over the feeder.

So I gave in and purchased an Erva Mealworm feeder. I like it very much, as do the bluebirds and the Carolina Wrens. They can now eat in relative peace and starlings can’t get in. (Every now and then a starling tries to hang on the feeder but they can’t nab more than a stray spilled mealworm or two. They mostly leave it alone now.)

The bluebirds come by for mealworms, washed down by a sip or two from the birdbath and maybe a few sunflower hearts a couple of times a day now. They never did claim the nesting box, but I’m still greatly enjoying having them in the yard.

Summer Bluebirds

The two bluebird pairs each had several young, nesting in other yards in the neighborhood. The bluebird parents then brought their fledglings to our yard for dried mealworms. So it was lively for awhile. But once the young bluebirds were fully fledged, I stopped seeing bluebirds in my yard.

They’ve been absent for the bulk of the warm summer months. I suspect they will start popping up in the yard again once it gets colder and bugs become more challenging to find. The dried mealworms should become popular once again.

Fall Bluebirds

November 2019: The last few days have turned cold here in Maryland with temperatures in the 40s and sometimes lower at night. I’m starting to see bluebirds pop up at the mealworm feeder again. I expect that there is less insect activity so the dried mealworms are once again interesting to them.

Spring Again: Nesting Bluebirds!

Now the calendar has circled again and this year a pair of bluebirds decided to nest in my bluebird box.
