September Teal Season 2026: Dates, Limits, and Why It Exists

It depends on the state, and September teal seasons are nine days in 2026 rather than the 16 they used to run. Nebraska opens earliest at September 5-13, 2026, in both the Low Plains and the High Plains. Missouri's is September 12-20, 2026. Arkansas's is September 19-27, 2026. Neither Dakota holds a separate teal season at all; North Dakota allows two bonus blue-winged teal per day from September 26 through October 4, 2026, and South Dakota allows two during the first nine days of each zone's season. Every state sets its own dates inside the federal September window, so check your own agency before you go.

The length is tied to the blue-winged teal breeding population. Under the federal framework a September teal season runs 16 days only when the spring breeding estimate tops 4.7 million birds, and 9 days when it falls between 3.3 and 4.7 million. The 2024 survey came in at roughly 4.6 million, just under the line, which cut seasons to nine days starting in 2025-26. The May 2025 estimate was lower still at about 4.4 million, roughly 13 percent below the long-term average, so the shortened season carried into 2026.

Blue-winged, green-winged and cinnamon teal, counted together toward one six-bird daily limit. Lookalikes are not legal, and the ones that get hunters in trouble are shovelers, pintails and wood ducks, which share water with teal in September and can look similar in low light. This is the reason several states push the start of shooting hours back to sunrise.

Green-winged teal, yes; blue-winged teal, no, and the difference is the whole story of this page. Blue-wings are largely gone from every state DuckCast covers before the regular seasons open, so there is nothing to forecast once the September window closes. Green-wings are a different bird on a different calendar: they arrive in October after the blue-wings have left, peak with the mallards in November, and outstay them into hard freezes, which is why the app scores green-winged teal as its own species with its own season curve in every state and opens on it in Texas and Mississippi. Both are legal in September and count toward the same six-bird limit; only one of them is still around in December.

Identification. A half hour before sunrise there is barely enough light to separate a teal from a shoveler or a wood duck, and only teal are legal. The federal framework sets hours at one-half hour before sunrise to sunset but carves out ten states, Arkansas and Missouri among them, where the season opens at full sunrise instead. The later start trades some of the best flight time for a fair chance at telling the birds apart.

Blue-winged teal migrate before any regular duck season opens. They tolerate cold poorly and are among the first ducks to leave in the fall, and most of them winter in Mexico or South America rather than in the United States. By the time a normal duck opener arrives in November, the blue-wings are largely gone. September teal seasons have existed since 1965 for exactly this reason: it is the only window in which those birds are still in the country.

Cold fronts, and earlier ones than most hunters watch for. Blue-wings do not wait for hard freezes the way mallards do; a September front with a real temperature drop and a north wind behind it is enough to move them, and their stopovers are short. That is why teal hunting is so front-dependent: the same marsh can be full one morning and empty two days later, and the birds that left are not coming back through.
