Three millimetres wide. That is the whole idea.

Fourteen Ounces
9.84 inches tall on a base 5.5 inches across, holding 14 fl oz. Small on purpose: nectar goes off in warm weather, so a batch you finish in a few days is a batch that never had time to go cloudy. The ant moat cup comes in the box with two S-hooks.

Five Ports, Each One 3 mm Across
Each of the five yellow flower ports narrows to a 3 mm opening. A hummingbird bill passes straight through it; blunter mouthparts stop at the plastic, and the nectar sits below the guard rather than at the surface. It removes the easy meal rather than promising anything absolute.

Wide Mouth, Warm Water, Done
The mouth is wide enough that a bottle brush reaches the whole inside, and the two-part base pulls off the glass so every surface the nectar touches is a surface you can get at. Hand wash in hot water — the base does not go in a dishwasher.

It Comes With The Bits You Need
The ant moat cup, two steel S-hooks and the two-part base all come with it, so there is nothing to buy before you can hang it. A cleaning brush is not included.

Hang it low. Watch who settles.

What guarded ports and a moat do that an open saucer cannot.
Frequently asked
questions.
The questions people actually ask before buying one.
They narrow every port to 3 mm, which a hummingbird bill passes through and a blunter mouthpart does not, and they keep the nectar below the opening instead of at the surface. That removes the easy meal. It does not make the feeder invisible to wasps — anything sweet hanging in a garden gets visitors — but they have far less to work with.
It is a separate red cup that hangs above the feeder on one of the two S-hooks included. Fill it with water; ants coming down the line reach the water and stop. Top it up when you check the nectar, because water goes faster than nectar in hot weather.
14 fl oz, standing 9.84 inches tall (25 cm) on a base 5.5 inches across (14 cm). The ant moat cup is 2.17 inches tall.
No — the base is not dishwasher safe and we would rather say so than let you find out. Hand wash everything in hot water. The mouth is wide enough for a bottle brush, so it is a quick job either way.
Five ports, with a scalloped tray running round the base for them to sit on. In practice one bird will often try to hold the whole feeder against the others — that is hummingbirds rather than anything about the design.
No. Any long-handled bottle brush fits through the wide mouth. The ant moat cup and two S-hooks are included.
Fill the glass, screw the base on, turn it over and hang it. The moat screws onto its long hook; on some units that takes a couple of attempts to line up and tighten properly, so work slowly rather than forcing it.
Free U.S. shipping and a 30-day return window. Hang it, give it a week or two, and send it back if it is not what you pictured.
