Although people cannot directly compare annual harvest numbers because of varying season lengths and bag limits, coupled with different methods of gathering data, most northern states harvest far more ducks now than a decade or two ago.
For example, during a 40-day season, North Dakota hunters bagged 77,600 ducks in 1961, said Paul Padding, chief of the USFWS Harvest Surveys Section. In a 50-day season in 1985, North Dakota hunters bagged 135,000 birds. In 2001, hunters in North Dakota bagged 694,700 birds during a 60-day season.
“We are certainly seeing more ducks being shot because of the longer seasons,†Checkett said. “With 10 more days on the front end, northern hunters can hunt a higher percentage of days so they shoot more birds.
North Dakota averaged about 365,000 birds a year in the 1970s. Now, they are shooting between 500,000 and 700,000.â€
During those same years, Louisiana sportsmen bagged 211,000 birds in 1960-61, 1.717 million in 1984-85 and 1.710 million in 2001.
In 1985, Louisiana hunters bagged about 31 percent of the birds taken in the entire Mississippi Flyway and 300,000 more than the entire Central Flyway.
Recent North Dakota bags contained high percentages of gadwalls and green-winged teal, two ducks that comprise the bulk of birds harvested in Louisiana.
Only so many birds hatch in a given year, and that figure dropped by 25 percent over the last five years. Any bird short-stopped by steel in North Dakota or elsewhere simply cannot fly south. Starting with smaller numbers and taking more along the way equals fewer and smarter birds that arrive on the Gulf Coast.
Also in the late 1990s, spinning wing decoys hit the market. Initially, these devices that simulate birds landing in ponds led to increased harvests even in marginal habitat. They work especially well for fooling young birds or birds unaccustomed to shooting pressure, increasing harvest rates of juvenile birds, especially in northern states.
