More birds ruby hummingbird feeder: quick verdict

The Ruby is a small glass hummingbird feeder with a red top and base, four flower-shaped feeding ports, and a built-in ant moat that the listing says stops ants before they reach the nectar. It holds 10 fluid ounces. It suits buyers who want a simple glass feeder with an ant moat and a modest nectar supply.

Specs at a glance

Extended verdict

Put plainly, the Ruby is the compact member of this small family. It gives you a glass bottle, a red top and base, four integrated perch feeding stations and an ant moat in a package listed at 6.5 x 6.5 x 8.75 in. and 10 oz. Its two siblings hold twice the nectar and add a fifth port, so the trade is size and refill frequency against a smaller, lighter feeder.

The listing is clear on its main features and silent on a few details, such as how long a fill lasts and how large the moat is. That is worth knowing before you order, because it means you will learn those details by using the feeder, not from the page.

Size and fit

Going by the listings, the Ruby is the smallest and lightest of the three. The Red Jewel is listed at 6.3 x 6.3 x 9.9 in. and 1.6 pounds, and the Vintage Glass at 8 x 8 x 9 in. and 1.8 pounds. At 10 oz, which is under a pound, the Ruby is the lightest by a clear margin once the units are lined up. The listing does not say whether that weight is the empty feeder or includes packaging, so treat it as approximate.

All three are hanging feeders, so check the hook, bracket or branch you plan to use. The listings do not state a hanging-weight limit, which matters more with the 20-ounce models once they are full of nectar.

Using it day to day

The description says the wide bottle opening and detachable flat base make filling easy and cleaning simple. Hand washing in warm soapy water is the listed method, so keep a small bottle brush or sponge nearby and plan to wash it each time you refill.

The ant moat only works as designed when it holds water, so glance at it whenever you check the nectar. The details list the included components as the ant moat and the bottle.

Who it suits

The Ruby's 10-ounce reservoir is the smallest of the three feeders, so it will need refilling more often than the 20-ounce models. If you plan to keep a feeder full through a busy season, check the reservoir size against how often you can refill it. The listing does not state how long a fill lasts, so plan for regular checks.

What to check before you buy

• The listing gives 10 fluid ounces of nectar, and the ports are flower-shaped with a red top and base.
• The built-in ant moat is a listing feature, so keep water in the moat as the design intends.
• The listing says to wash the feeder by hand with warm soapy water and not to use the dishwasher, because high heat can damage the parts.
• The details list the material as glass and plastic, and the description calls the bottle glass.
• The listing says red is a hummingbird's favorite color. That is a manufacturer's claim, so treat it as the listing's view.

How it compares

How it compares. The More Birds Red Jewel holds 20 fluid ounces, has five red metal flower ports and polished copper accents. It is the better choice if you want a larger reservoir.

Both alternatives list five feeding ports, while the Ruby lists four, which is one of the clearest differences in the listings.

The More Birds Vintage Glass also holds 20 fluid ounces, with five red flower ports and an aqua-tinted antique glass bottle.

Alternatives in more detail

The two larger feeders differ from each other as well as from the Ruby. The Red Jewel has an eight-sided red glass bottle, a metal basin cap with five polished red metal flower ports and copper accents, and a 600 ml capacity in the details. The Vintage Glass has an aqua-tinted antique glass bottle, five red flower ports, a metal hanger and a construction that comes apart into three pieces for cleaning.

The Ruby is also the only one of the three with the colour name Ruby Red in its listing, and its listed theme is Ruby Hummingbird, which is a styling note rather than a performance claim. Neither alternative lists the Ruby's built-in ant moat in its bullets, so if ants are your main worry, that is a point for the Ruby. If you want to refill less often, both 20-ounce models are the better fit. For a wider look at what is available, see our guide to hummingbird and oriole feeders.

Capacity is the clearest numerical gap: 10 fluid ounces against 20 fluid ounces on each alternative. The Red Jewel's details list 600 ml, which is consistent with a 20-ounce bottle, and the Ruby's list 295 ml, consistent with 10 ounces. In other words the larger two hold roughly double, and the listings agree with themselves on this point.

Questions to ask before ordering

• Is 10 fluid ounces enough for how often you can refill and clean the feeder?
• Do you have a hanger rated for the feeder's full weight?
• Are you happy to hand wash it, since the listing says not to use the dishwasher?
• Do you want an ant moat, or is a bigger bottle more important to you?

Conclusion

The More Birds Ruby Hummingbird Feeder is a simple 10-ounce glass feeder with four flower-shaped ports and a built-in ant moat. It is the most compact of the three feeders in this review, and it is the only one whose listing includes an ant moat in its bullets. Its smaller reservoir means more frequent refills, and the listing calls for hand washing rather than the dishwasher. It suits buyers who want a modest glass feeder with an ant moat, while buyers who want a larger reservoir should look at the Red Jewel or Vintage Glass, which each hold 20 fluid ounces. This verdict is based on listing data only, and the ant moat's effectiveness is the manufacturer's claim.
