Highest US waterfowl population in 59-year history

Postby Fitter » Fri Jul 18, 2014 7:33 pm

Waterfowl breeding populations in 2014 are mostly good to excellent in Wisconsin and North America, according to recent surveys by state, federal and Canadian wildlife officials.

The surveys were conducted by Wisconsin Department of Natural Resources, the U.S. Fish and Wildlife Service and Ontario Ministry of Natural Resources. The USFWS survey showed the highest North American duck population estimate in the 59-year history of the survey.

"While some recent variations in state level waterfowl surveys are difficult to interpret overall, we have excellent news regarding waterfowl populations in North America," said Kent Van Horn, DNR migratory waterfowl biologist. "Population data is good to excellent across North America with good wetland conditions to support promising local and continental duck and goose populations."

The full report is available by searching the DNR website dnr.wi.gov for "waterfowl breeding population survey http://dnr.wi.gov/topic/wildlifehabitat ... wlsurv.pdf.

In addition to Wisconsin's breeding population study, two additional sources of information regarding yearly waterfowl breeding conditions are used to determine fall season structure.

A cooperative survey organized by the Ontario Ministry of Natural Resources provides annual data on Canada geese. Roughly 60 percent of Wisconsin's regular goose season harvest is supported by Canada geese nesting in northern Ontario.

A final piece of supplemental information is provided by the USFWS through their breeding waterfowl survey for the northern U.S., Canada and Alaska.
Ducks

Waterfowl breeding areas in North America showed mostly good to excellent conditions in 2014. The quality of duck breeding is expected to be high overall. Wetland conditions were on the rise in all regions of Wisconsin's breeding waterfowl survey - this should provide good brood rearing habitat. However, widespread flooding, a late winter and irregular migration timing impacted survey conditions and created challenges in generating state population estimates.

The four most abundant ducks in Wisconsin's fall hunting harvest make up close to 75 percent of the total harvest and include mallards, wood ducks, green-winged teal and blue-winged teal. Van Horn notes that many of the mallards and wood ducks harvested in Wisconsin come from birds that breed in Wisconsin, while about two-thirds of the blue-winged teal harvested in Wisconsin are raised in other prairie regions. Most green-winged teal migrate into Wisconsin from boreal forests in Canada.

"The recent trend of wet conditions, increasing duck numbers and liberal regulations is very exciting," said Van Horn. "Many older waterfowl hunters have experienced years with drought, shorter seasons and low breeding populations -- with the help of many agencies, conservation organizations and hunters, we have placed ourselves in a position to enjoy great hunting all over the continent."

In Wisconsin, the spring waterfowl survey provided mixed results, with a total breeding population estimate of roughly 395,000 ducks. This estimate shows a decrease from 2013 and is below the long term average.

"These are population estimates, not exact counts, so changes of 20 percent (whether an increase or decrease) may not reflect any real change in the actual population and are best viewed as trends," Van Horn said.

The trend in the total breeding duck population in Wisconsin has been relatively consistent the last ten years in the range of 500,000 total ducks. The mallard and wood duck portions of this state total have provided more stable contributions, while the blue-winged teal and "other duck" survey estimates have been more variable.

Mallards are the number one duck in the fall bag, accounting for nearly 40 percent of the total fall duck harvest in Wisconsin. The 2014 continental mallard population estimate of 10.9 million is the second highest on record. The Wisconsin mallard population estimate of 159,000 is statistically unchanged from 2013 and consistent with a stable trend experienced over the past ten years.

The second most abundant duck in Wisconsin, registering at close to 20 percent of the total fall harvest, is the wood duck. The 2014 breeding population estimate of 104,000 is similar to 2013 and consistent with a stable trend experienced over the last ten years.

The continental blue-winged teal estimate of 8.5 million was the third highest for that species, while the 2014 Wisconsin blue-winged teal breeding population estimate of 34,000 is down from 2013. A trend in the state population estimate for blue-winged teal for the last 10 years is not clear, due to challenging survey issues and high annual variation in population estimates.

Conservation funding and the efforts of Wisconsin's waterfowl hunters have protected and managed wetland and upland habitats crucial to the maintenance of these breeding duck populations statewide.
Canada Geese

The 2014 Wisconsin breeding Canada goose population estimate of 126,000 was similar to 2013 and the average spanning the last decade. Wisconsin's resident breeding Canada goose population may be stabilizing at 120,000 after a long term increase.

"We expect a healthy Canada goose population this fall, particularly for the Early September Canada goose season (Sept. 1-15 with a five-bird daily bag limit), which makes up one-third of our total statewide goose harvest" said Van Horn.

According to Van Horn, two populations of Canada geese represent most of the geese in Wisconsin during the fall. Wisconsin's locally breeding Canada geese represent over 90 percent of the goose harvest for the early season from Sept. 1-15 and about 40 percent of the harvest during the later regular goose season.

Most of the remaining 60 percent of regular season goose harvest is supported by a second population of Canada geese that breed along the Hudson Bay coast in northern Ontario. Although Wisconsin shares this population with other states, it is unique in that these birds comprise over half of the state's annual harvest. In neighboring states, like Minnesota, locally breeding birds comprise the majority of harvest. This breeding population of Canada geese appears to be at normal levels, with an estimated 2014 breeding population of 323,099. These data are similar to estimates in 2013 and the long term average.

Overall, 2014 looks to be an excellent year for duck and Canada goose populations. With survey data now available, federal and state biologists are conducting analyses and harvest projections to help form hunting season structure in the coming weeks. As a part of this process, DNR staff will meet with state, federal and provincial agencies at the Mississippi Flyway Council meeting in late July. Following the council meeting and USFWS Regulations Committee meetings, these organizations will use further coordination to guide 2014 waterfowl hunting regulations.

The problem as I see it with duck populations in Wisconsin is that there are far to many geese. I am seeing large populations of geese where we never saw geese in the past 4 decades that I am aware of. My favorite inland lakes are holding nesting populations too high for the areas. Few if any ducks are seen anymore on some of these waters. Along the shores of Ashland and up to Bayfield on Lake Superior the geese are everywhere all summer long. Do we need to thin the population? I think so, but I do not know many goose hunters around here anymore.

In relation to the numbers of geese I can relate. I see a lot here on the shores of lake Michigan as well as in my pond. But far more than seeing the geese you only find the waste they've left behind. I visit marinas, docks, boat launches, and beaches throughout the summer. So many times I find that picture perfect spot has already been visited by geese.

send them all this way, I will do my best to thin the population
