26 Nebraskaland • August-September 2021 and markings of a duck wing's feathers. The envelope then is marked with that wing's sex and age. The empty envelopes get mailed back to the Service, where a person will scan the barcode to record age and sex. For geese, species and age are determined; sex of geese can't be determined from the tail feathers. For goose tail feathers, color, length and shape are evaluated. All goose tail feathers were shipped to checkers in Texas for evaluation this year. Lincoln's mini-Wingbee Over several days in late January and early February of this year, Stutheit led Lincoln's mini-Wingbee. He was joined by a group of wildlife biologists, wildlife technicians, professors and university students. They evaluated 1,685 duck wings of mallards, northern pintails, American wigeon, blue-winged teal and green- winged teal from across the flyway. As a wing checker, Stutheit kept a watchful eye over everyone else's work. The data they collected will be used to help formulate waterfowl regulations for 2022. "It's pretty cool that they just didn't cancel the Wingbee this year because of COVID-19, but that they did choose to go ahead and ship wings and tail feathers out to various experts across the Central Flyway to work on them in our home states," Stutheit said. While some of the work was done at Game and Parks, other sessions were hosted at the University of Nebraska- Lincoln. Students in the Waterfowl Ecology and Management class of Dr. Mark Vrtiska, Professor of Practice, at the School of Natural Resources, got to participate. "I think it's a pretty special opportunity for college students that are majoring in this field to take part in a survey like this," Stutheit said. "You just don't get that opportunity otherwise." The students get hands-on experience and much-needed practice identifying ducks. "What they gain from it is that practice of doing it and knowing how to age and sex duck wings and recognizing you can do it," Vrtiska said. "But part of my waterfowl class has a waterfowl ID component that we'll have a quiz on. It helps them not only just to gain some experience but to help them in their ID of waterfowl." How Collected Data is Used The information gathered at Wingbees not only breaks down harvest by species, it breaks it down by state and county. Each wing or tail envelope includes information about where the waterfowl was harvested. "What this does is break down duck harvest by species composition," said Vrtiska, a former Game and Parks waterfowl program manager. "For example, if it's determined that there are a million ducks shot in the Central Flyway, with this Wingbee, you can determine out of that million birds harvested that there's 500,000 mallards, 200,000 green wings, 100,000 gadwall, etc. "That data can be useful for looking at trends of where ducks may or may not be harvested. You can break that down by state. In Nebraska, duck harvest will be about 100,000 birds. We know 50,000 of those birds are mallards." A Checker's Beginning Stutheit had been participating in five or six Wingbees when, one year, a checker who was planning to retire noticed his work examining wings. "He'd been watching how I'd been doing, aging and sexing wings and he thought I was getting fairly proficient at it," Stutheit said. "He asked me if I'd be interested in becoming a checker. I said, 'Oh, yeah, definitely'." Stutheit and three other biologists from California and Oregon in the Pacific Flyway were then flown to Laurel, Maryland, for training to become checkers. "Really what we did is just look at more wings. The only way to really become good at this is to look at a lot of wings." He took a test in which he had to correctly identify at least 95 out of 100 wings. "If we did well, we would get a slap on the back, and they would say 'Congratulations, you're checkers!' " Vrtiska has been to several Wingbees with Stutheit, around 15. He's not an official wing checker, but he has aged and sexed wings and goose tails. He said the comradery that builds among the individuals present results in a familiarity with each other's skills in evaluating wings and tails. "The checker will know because he's going through everybody's wings at his table and he or she can determine that person isn't missing very many of these wings," Vrtiska said. "There is a little bit of an art – and there is definitely a science to it – but I think the cream rises to the top, and you get to know people who are very good at it. They just don't miss very many." Stutheit hasn't missed many Wingbees or wings over the years. A very good thing for the waterfowl, whose numbers have remained healthy because of checkers like him.
