Curva Modern Bird Feeder (1" Pole Mount)

from $79.95

The Curva Modern Bird Feeder is an open Corten steel birdseed feeder with a gently curved profile, designed by Zac Feltoon. It stands 7" tall and 11" across the top. It mounts on any 1" outside-diameter feeder pole with an optional Erva mounting flange.

Designed to blend seamlessly into your garden

Curva's profile gives it a distinct shape without competing with the plants around it. It fits a modern garden, a patio, or a natural landscape equally well. The open form gives birds an inviting place to feed and gives you a clear view of who is visiting.

Built for pole mounting

The optional Erva mounting flange fits a standard 1" outside-diameter pole and locks in place with a thumbscrew. You can easily lift the feeder off for cleaning and refilling. A feeder mounted on a pole is steadier in the wind than a hanging feeder, so it stays level and is easier to photograph.

Curva is part of our 1" pole system. It does not fit the ⅝" poles used with the hummingbird nectar feeders in our other kits.

Corten steel that changes with the seasons

Curva is made of Corten steel, also called weathering steel. Outdoors, its surface develops a rust-colored patina, and that patina protects the steel from further corrosion. The color develops over several months to a few years, depending on rain, humidity, and sun. Each feeder takes on its own character as it settles into the landscape, and there is no paint or coating to maintain.

A note on the patina. Curva's finish keeps evolving after it arrives. Its color and depth shift with exposure and local weather, so no two feeders look exactly alike, and the same feeder will look different a year from now. While the patina is still forming, rain can carry rust-colored runoff from the steel.
