Breeding Duck Numbers up 8 Percent

Abundant precipitation boosts breeding pair estimates again
The US Fish and Wildlife Service today released its report on 2014 Trends in Duck Breeding Populations, based on surveys conducted in May and early June. Total populations were estimated at 49.2 million breeding ducks in the surveyed area. This estimate represents an 8-percent increase from last year’s estimate of 45.6 million birds, and is 43 percent higher than the 1955-2013 long-term average. This continues a three-year trend of exceptional water conditions and population numbers for many species.
“It looks like another good waterfowl breeding year for a good portion of the prairies and the boreal forest,” said DU CEO Dale Hall. “Precipitation in the form of snow and rain has provided sufficient water to fill important wetlands in key breeding habitats. We hope this will result in good production and another great flight of birds migrating in the fall. DU and its partners continue to work hard to protect and restore habitat to provide for the needs of these birds and so much more. While we still have much work to do in delivering habitat and securing key conservation policies for sustaining these populations, we are heartened by the good results we have seen in the past few years.”
The main determining factor for duck breeding success is wetland and upland habitat conditions in the key breeding landscapes of the prairies and the boreal forest. Conditions observed across the U.S. and Canadian survey areas during the 2014 breeding population survey were improved or similar to last year. Total pond counts for the U.S. and Canada combined showed 7.2 million ponds, which is similar to the 2013 estimate and 40 percent above the long-term average.
“Reports from DU biologists indicate a strong breeding effort across the prairies,” said DU Chief Conservation Officer Paul Schmidt. “This is despite late winter conditions that delayed nesting activity in some areas by one to two weeks. We need more moisture in the Western Boreal Forest and in parts of southern Alberta and Saskatchewan, and higher-than-usual water levels have posed some challenges for nesters in the Eastern Region. But overall this is a good breeding season, and depending on local conditions hunters across North America should look forward to another strong fall flight.”
“This spring, as has been the case for the past several years, saw abundant moisture across much of North America’s most important duck breeding areas,” said DU Chief Biologist Scott Yaich. “That bodes well for duck breeding success this summer and, we hope, for hunting this fall. But we remain concerned with the continuing and escalating loss of nesting habitat in these areas. Because ducks need water, wetlands to hold the water and upland habitats to successfully raise their young, the ongoing loss of grasslands and wetlands across the Prairie Pothole Region will increasingly impact the number of ducks in the fall flight in the long-term.”
The spring surveys provide the scientific basis for many management programs across the continent, including hunting season dates and bag limits. The four flyway councils and the US Fish and Wildlife Service Regulations Committee will meet in late July to recommend the season structure and bag limits for 2014-15. Individual states will make their specific selections within a federal framework of season length, bag limit and dates. Hunters should check the rules in their states for final dates.
