Mosaic’s Hummble Bold glass hummingbird feeder is my new favorite small hummingbird feeder. I’ve been looking for a really small hummingbird feeder for a while now and settled on this one. I like it a lot.

Why I Wanted A Smaller Hummingbird Feeder
This is my fourth hummingbird feeder. The first two are fairly large, a plastic Aspects HummZinger Hummingbird Feeder and a Perky Pet Mason Jar Hummingbird Feeder. The third is a smaller version of the Aspects hummingbird feeder. They are all good feeders and work fine.
The trouble with the two larger feeders (for me) is that I just don’t get enough hummingbirds in my yard to justify them. And even when I do get several hummers, one usually chases the others from the feeder so I never see more than one feeding at the same time.
In our hot Maryland summers, I found myself constantly mixing up a new batch of sugar water just to dump most of it out a day or two later to keep things safe. You don’t have to fill these feeders completely of course, but I still felt like I was filling, dumping and cleaning bigger feeders than I needed and going through a lot of sugar just for a couple hummers. So I purchased the smaller plastic one a few years ago.
The smaller one did work better for the number of hummingbirds I typically get in my yard. It was easy to use and fill. But the little faux flowers on the feeder ports of all of these feeders have a tendency to develop tiny bits of mold. Cleaning out the flowers’ little crevices, even with a tiny feeder brush, was a pain. Tiny bees were also getting in through the ports and drowning. And I really wanted an even SMALLER capacity feeder that was easier to clean.

Choosing the Mosaic Bold Hummbler Feeder
So several weeks ago I looked over the hummingbird feeders on display at my local bird store, Mother Nature’s. They had some even smaller plastic feeders, but I found them awkward to open (which would probably lead to spilled sugar-water) and to be honest, I didn’t like the construction. I didn’t think they would last long.
But then I saw this Mosaic glass and metal hummingbird feeder on display. I liked the size and look of it. It was the last one they had, so I bought the display feeder minus the box. I’ve been using it for about a month now and the hummingbirds seem to like it a lot and so do I.

Why I Like Mosaic’s Small Hummingbird Feeder
This feeder is made up of three simple pieces: a glass bowl, a glass lid with four 3mm holes and a coated metal frame that forms a hook at the top for hanging. The feeder holds just a little less than a half cup of sugar-water and you could probably even fill it only half full and still be fine. The glass lid rests on top and is easy to take on and off.
Because it is a simple glass design, this feeder is very easy to clean. There are no little flowers to scrub out; simply smooth glass surfaces. It makes it quicker to clean and less likely to get mold. So far I haven’t seen a speck of mold on this feeder.
To use the feeder, hang the metal frame up by the hook. Fill the container with sugar-water, put the the lid on top and lower it into the feeder frame’s middle circle. That’s it.

Glass Lid Considerations
Reading online reviews for this feeder, apparently some people have had problems with the lid falling off and getting broken. I do see how this could happen. At first I had this feeder hanging on a limb of a small tree not too far from the salvia flowers that the hummers love so much. The hummingbirds found the feeder quickly and started using it, but squirrels like to jump around on that little tree. I’m not sure if the squirrel was trying to get into the feeder or was just squirreling around in the tree, but I heard the lid fall to the ground with a clink and saw the squirrel jump away.
Fortunately the feeder lid landed on grass and not my cement sidewalk, so it was fine. But I decided to move the feeder to a larger tree on the other side of the flower bed where I could protect it with a squirrel baffle. I’ve had no further problems. I do think I’ll take the feeder down on very windy days just to be on the safe side as the baffle could cause the feeder to kite around in the wind without added weight.
(Sept 2021 Update: I actually came up with a different windy day strategy: I filled an old cage suet feeder with small weights and on windy days, I hook the cage to the bottom of the feeder so it stays in place. It is very easy to take on and off and doesn’t seem to bother the birds a bit.)
Hummingbird Competition Around Feeders
This feeder’s current location is about four feet from my back bench, so I get a close view of the two female Ruby-Throated Hummingbirds that are using the feeder. Whenever they meet up at the feeder at the same time, there is a short aerial battle ending when one flies off and the other goes to the feeder.
(Sept 2021 Update: After a summer of watching the two females, a male Ruby-Throated Hummingbird appeared very late in the season. I suspect he was migrating through as he only stayed a few days. Male hummingbirds can be especially aggressive around their food sources. He spent more time chasing the two females away from “his” feeder and flower beds than he actually spent eating. I’m thinking of getting a second of these feeders next year for the front yard. For this year, I pulled out the old small plastic feeder to use there while he was around.)
Mosaic Feeder Versions
Feeder’s Glass Top and Base
The particular feeder I purchased is all red glass with a red frame. More typically, these seem to be sold with a red glass top and a clear glass base so you can keep a better eye on the water level and clarity. Replacement lids can be purchased from the company if you should happen to break one. (Some reviewers have said they secure the lid with a rubber band but I haven’t found that to be necessary.)
The woman who sold me the feeder said she had one at home herself and at other times of the year she takes off the lid to instead use the feeder to offer things like mealworms. So it actually can be a year-round feeder and not just something you use in the warmer months.
Feeder’s Frame Versions and Colors
This hummingbird feeder has two frame versions. As you can see in the above pictures, the Hummble Bold version I have includes both a vertical circle and an extra horizontal circle, creating a “globe” shape. This allows for a hummer to perch while using the feeder if they like. (Yes, there are two M’s in the name.) The company also sells a slightly less expensive Hummble Slim version that doesn’t include the extra horizontal circle.
Mosaic says, “All of our feeders are manufactured using BPA-free 40% recycled glass and rust resistant metal.” The glass is lead free. They also offer the powder-coated metal frames in a variety of colors, which I think could be a lot of fun, especially if you have several of them. (While this feeder does not hold a lot of sugar-water, if you want more capacity, you can purchase additional feeders and hang them from each other in a vertical line of feeders using the hook at the top of the feeder frame and the bottom loop of the vertical circle.)
Mosaic also offers Basic feeders in the same two frame versions but without the lid for a little less cost again. And they have a pretty line of orange glass oriole feeders on their website as well.
If you are looking for a nice looking, small, easy to use and clean hummingbird feeder, definitely check this one out.

Hello, I currently have a larger feeder and would like to switch to a smaller one like this. However, I have an ant problem and the water filled reservoir on the larger one keeps them out. Do you know if a way I could protect this smaller one from an ant invasion? Thank you!
Hi Sue,
I have a separate clear plastic ant moat that you fill with water and hang above a hummingbird feeder for exactly that purpose. You can see the very bottom of it above the feeder on the fourth picture in this blog post. It has a metal hanging loop at the top and a separate metal S-hook at the bottom that you can use to hang the hummingbird feeder from under it. I hung this ant moat over the feeder when it was simply hanging from the small tree but when I switched to the big tree with the big baffle over it, I decided to see if the baffle would thwart ants. So far no problem, but maybe I’ve just been lucky. Note: Mosaic also suggests that to keep ants away from a hummer feeder, be very careful not to drip any of the liquid underneath where the ants can find it to locate the feeder.) I purchased the ant moat from my local bird store, so you might check if you have a local store. It says “Nectar Protector Jr.” on it. Here is an Amazon link for it: https://amzn.to/3BQSBud. (Note: I suspect that you might get it cheaper in your local store since shipping won’t be built into the price.)
