If you feed them well, particularly during very cold weather, they will come. Also a heated bird bath attracts them as well. My Blues love to bathe, even in the middle of winter. But more importantly, they will need access to clean, unfrozen water for drinking. I also feed them mealworms and suet (great recipes on sialis.org.) A lot of people set up a Bluebird feeder so the larger birds can't hog all the food. I have my feeder on a pole with a stovepipe guard so the squirrels and chimpmunks don't steal all the food. I hope this helps.

Yes, very helpful thanks! I didn't know bluebirds would ever come to a feeder?? I will have to check into that and also the heated bird bath!! They have been coming around some lately and what I love...they bring the family! Soo neat! What kind of food do you put in the blue bird feeder? Thanks for the info...I am still learning!!!

Shelter and Housing - Bluebirds that are year-round residents will always be seeking shelter for roosting and for bad weather. Our bluebirds sleep in there sometimes. When warm weather comes around, they will remember these for nesting. They will defend these sites from other competitors, making a claim even during the winter. The sooner houses are available, the better chance the bluebirds have to claim them and hold that claim.
Clean water for drinking and bathing - especially when other sources are frozen.
Food - natural foods such as berries, plantings that provide shelter and safe cover to hide from predators.
Feeders can be offered in a covered feeder - mealworms (will die if frozen, but birds might still eat them), peanuts, sunflower chips, or raisins. Remember that other birds will discover these food sources too (Chickadee, Titmouse, Carolina Wren, Nuthatch). In my opinion that's OK unless they are HOSP or EUST; then I quit offering food for a while. Never offer seed mixes especially millet, as bluebirds cannot digest these and it attracts the HOSP and EUST. There are feeders with holes that will allow only smaller birds to enter (a good investment for any time of year), and bluebirds will learn from the other birds how to get in.

kendra2 i was surprised to see that you are in MA and in zone 5 and have year round BB's. I am in SW Vermont in zone 4 (or 4B depending on where you look) and have been seeing BB's later and later each year and wondering what is going on as i thought they went south for winter.

It is hard to tell from the posts what is happening because not everyone identifies where they are located and what zone they are in but it appears they will overwinter wherever they can.

It seems unimaginable that BB's would overwinter in my region because it can go to -20 here at night and be in single digits for days at a time. Typically there is a stretch of 2 or more weeks in winter that don't exceed the teens. These temps are mitigated only slightly till one travels at least 75 air miles to Albany and the lower Hudson valley.

Nevertheless, I have seen BB's later and later in the year on nice days until I eventually stopped seeing them in late November. This year I saw groups of BB's around the nest boxes on nice days several times in November and December. On Christmas eve I saw a pair perched near the house going into the snow to pick up something. This weekend is supposed to be in the high 40's and i kind of expect to see them again.

So my question is: are they overwintering here or making "day trips" to their nesting grounds and why on earth would they be doing that in such a difficult environment when they could be in Carolina eating fresh fruit and bugs?

Lou,
It is speculated that some Bluebirds risk starvation in winter in order to be the first to claim nesting cavities in the spring. The first time I saw Bluebirds in the winter, it was during a particularly frigid spell with temperatures well below zero, which lasted for weeks. I couldn't believe my eyes when I saw them, but I had been growing mealworms to feed to them when they came in the spring, so I quickly started feeding and watering them. I think some of them may have succumbed if I hadn't, because a few of them looked like they were starving to death. After that winter, they have visited me every winter. I guess knowing a source of food and unfrozen water is available lures them here. My yard is such a minuscule part of their territory, so they are certainly around elsewhere as well.

Kendra2 I am amazed that you have seen them in below 0 weather. So far i have only seen them on nice days and assume they overwinter in some sheltered location somewhat nearby.

I do not grow mealworms but do grow red wrigglers and have access to them whenever i want. Do you think the BB's would eat them if I put them out even though they would freeze solid in a short while? If they would eat them should they be chopped up? If you don't know red wrigglers they are smaller than earthworms and commonly used to degrade and digest compost turning it into worm castings.

Also, I have never seen BB's at the "meat" feeders i hang out. I put venison meat/fat in them and woodpeckers, titmouse, nuthatches and others seem to love it but the blues don't - nor do they eat the black oil seeds. Do you think they avoid my "meat" feeders because of the competition, the cuisine, the lack of a special feeder like the one above, or what?

I am in the boonies and have to drive 30 miles to buy mealworms - which i am not likely to do - so any suggestion to help them out would be appreciated.

thanks...........Lou

Lou, make peanutbutter suit (recipies found on www.sialis.org) and mail order meal worms (also found on that website).

I agree with Lisa that making them suet from a recipe on the sialis site would be very attractive to them. That's where I got my recipe. I'm amazed any birds can survive in sub-zero weather with those tiny legs of theirs, but they do. I mail order my mealworms, and grow what I can too. I have no idea if they would like red wigglers, or if they'd be good for them. Here is an old photo from the first year they showed up. It was so cold the mealworms were freezing almost instantly. It makes it look like Mr. Bluebird is smoking a cigar.

Great picture, Kendra. I am not equipped to set up a bath until it's warm again but i think next summer i'll prepare better and build a feeder/watering hole for them. I am going to start a new thread to find out if they like red wrigglers as i have them handy. I haven't been seeing them since winter really set in here after Christmas. Next year i will be better prepared.

You know the TRES have picked up on how the BB's get an early start on nesting and last year took over a box that had usually hosted BB's. The BB's came early and hey had already put some grass in it and "staked their claim". Then a TRES tenaciously sat on the box until it was his/hers. I was upset but didn't interfere and the BB's moved on to another box. But that's another subject.

Thanks........Lou

This is the first winter that I have had a lot of success keeping bluebirds coming around during the winder. I think it must be a family from the past breeding season. But there are seven of them (one female and six males)who were coming to the feeder until this past week when a mockingbird started guarding the feeder and chasing all my birds away! Argh! I think they must have gathered together in my bluebird house during the unusually cold winter we've had in Atlanta. I know they were in there during the snow. Saw them all emerge to look for food.

Anyway, they love the seed I use in the feeder! All 7 of them will come to it at once. Quite a site. Its a mixture of hulled sunflower seeds, suet crumbs and a little millet. Its a mix I was getting and Wildbirds. When they closed, the owners set up a delivery service. It attracts the widest variety of birds I've ever gotten. Unfortunately, this year the mockingbird values it so much he is attacking any other birds that come near.

Dawn, I am in NW GA, and I have had success with feeding the Blues. Last winter, I had them coming often to 4 different types of feeders for raisins and Bluebird Nuggets. Of course, mealworms are always a favorite. I also own a heated birdbath which they do come to. This winter though, I am not seeing them at my feeders. I'm not sure why that is. Here is a pic of my favorite Bluebird feeder.~~Angie
