This video was produced by the Michigan Department of Conservation featuring Chuck Floyd. This production features Michigan Department of Conservation cartoonist Oscar "Ozz" Warbach as he illustrates various wildlife found in the state of Michigan. The video is undated, but it is believed to be around 1954-1957.
A Peregrine falcon (Falco peregrinus) chick after being banded by a DNR employee. Young peregrine chicks are banded so they can be identified later should they turn up in another state or are found injured. The peregrine falcon population was decimated by the use of the pesticide DDT in the 1950s and 1960s. The DNR has worked with other agencies to successfully restore peregrines in Michigan, and the banding program helps in these efforts.
A moose cow in winter, fitted with a radio collar by the DNR to help track the state's moose population.
Fisheries Division employees use gill-nets to survey inland lakes for cisco, also known as lake herring. The survey has two purposes - to find out where cisco populations exist and to, potentially, serve as brood stock lakes should the DNR ever decide to re-introduce the creatures into other waterways.
A smallmouth bass (Micropterus dolomieu) that will be tagged by DNR employees on an inland lake as part of the Large Lakes Program. This program specifies that one to two lakes, which are 1000 acres or larger, are scheduled to be surveyed every year. The fish tagged will be walleye, northern pike, musky and smallmouth bass. This study is designed to better determine population abundance, growth and survival, and harvest and fishing pressure.
The crew of the DNR's Survey Vessel Steelhead prepare a trawl mesh bag by attaching a digital sensor. The crew conducts an annual hydroacoustic (sonar) and mid-water trawl survey of alewives and other prey fishes (like the mottled sculpin) in Lake Michigan to get a snapshot of current conditions. Once the survey work is completed, estimates of total prey fish abundance are generated by managers and are used to balance predator-prey dynamics. Fisheries managers then adjust salmon stocking rates to keep alewife abundance in check with lake productivity levels.

Two peregrine falcons (Falco peregrinus) fly around buildings. The peregrine falcon population was decimated by the use of the pesticide DDT in the 1950s and 1960s. The DNR has worked with other agencies to successfully restore peregrines in Michigan, and the banding program helps in these efforts.
Small or big brown bat at Millie Hill Bat Viewing Site. The site is actually an old mine entrance that has a protective steel grate that allows bats to enter and leave, but keeps people out of the mine shaft. The Millie Mine is a critical hibernating and breeding location for up to 50,000 bats—one of the largest known concentrations of bats in the Midwest. Big brown and little brown bats from all over the region come here to hibernate during the cold winter months.
DNR employee holds a recently born black bear (Ursus americanus) cub. Cubs are born around January and stay in the den with the mother during the late winter months. The mother of these cubs was tranquilized and given a radio collar to help biologists track and check up on the species in Michigan.

DNR biologist Jessica Mistak measures the size of a mussel in the Menominee River watershed for her research project, which examines freshwater mussels, including the purple wartyback and elktoe, trying to determine their populations as well as unlocking the secrets to where they live.
Biologist Barb Barton captures Mitchell's Satyr butterflies in Jackson County as part of a mark-and-recapture program. The adult butterflies are caught, marked with a number on a wing with a fine-tipped felt pen and released. The number of times the marked butterflies are recaptured compared to the overall number of specimens captured gives biologists an idea about the size of the population.
Two moose, who are designed to withstand the heavy snows and cold temperatures of Upper Peninsula winters, resting in a glade.
A group of DNR employees and volunteers work on handing off coralled Canada geese individually to be banded. The DNR is responsible for banding hundreds of ducks and geese each year, with quotas set by the U.S. Fish and Wildlife Service according to local conditions. The banding process is performed by DNR employees and trained volunteers. Once the age and sex are recorded, a metal, pre-numbered, federal ID band is placed loosely around the goose's leg and gently pushed closed with a pair of pliers. Waterfowl hunters across the United States and Canada are asked to report any harvested birds with federal identification leg bands. Doing so assists waterfowl managers when it comes to setting future hunting seasons and bag limits.

Internal/PIT tags and implanter. These are implanted into a fish and contains a series of numbers and letters that can be obtained by passing a "PIT Tag reader" over the implanted tag. The tagging program helps biologists to determine movement and seasonal distribution of the species.
Adult and youth collect an American Beaver (Castor canadensis) from a trap. The DNR has established specific trapping seasons when furbearers may be taken. Wildlife biologists recognize trapping as an important wildlife management tool and regulate and scientifically monitor trapping to ensure that the most humane methods are used and that the population is never endangered.

DNR employees fit a white-tailed deer with a radio collar for a predator/prey research project. The project will provide information about the local deer population and the effects of predators on it.
A biologist takes a sample from a walleye to be tested for Viral Hemorrhagic Septicemia virus (VHSv) as part of a program monitoring the deadly fish disease. In 2007, a total of 8,933 fish from 36 species were collected by DNR Fisheries Division personnel and tested at the Aquatic Animal Health Center lab at Michigan State University.

A group of DNR employees, boy scouts and volunteers extricate mallard ducks from a net to be banded near East Lansing. Every year, the DNR attempts to band ducks as part of a national survey, which focuses on mallards, wood ducks and black ducks. The mallards are affixed with aluminum bands; each with its own unique number, plus a phone number and address. Hunters who later harvest a banded duck are encouraged to report the bird's band number to the telephone number or address printed on the band. The goal of this program is to engage hunters in the collection of data about ducks and to help set quotas and establish hunting seasons that coincide with migration patterns.
The DNR Fisheries Division research vessel 'Chinook' trawling on Lake Huron. The ship has been used by the DNR for a variety of purposes since 1947.
A Peregrine falcon (Falco peregrinus) coming in for a landing. The peregrine falcon population was decimated by the use of the pesticide DDT in the 1950s and 1960s. The DNR has worked with other agencies to successfully restore peregrines in Michigan, and the banding program helps in these efforts.
A volunteer releases a mallard that has been freshly banded near East Lansing. Every year, the DNR attempts to band ducks as part of a national survey, which focuses on mallards, wood ducks and black ducks. The mallards are affixed with aluminum bands; each with its own unique number, plus a phone number and address. Hunters who later harvest a banded duck are encouraged to report the bird's band number to the telephone number or address printed on the band.

Wildlife Services employees from the U.S. Department of Agriculture oils double-crested cormorant eggs in a nest to prevent young from hatching as part of a population control measure on the Les Cheneaux Islands in Lake Huron. The booming cormorant population has been pointed to as a reason behind the decline of certain sport fisheries. The DNR works with the U.S. Fish and Wildlife Service in recommending sites for population control.
A banded piping plover perches on a piece of wood. While the Great Lakes population of piping plovers has rebounded since it was first put on the federal endangered species list, the population remains extremely vulnerable to both natural and human-caused disturbances.
Fisheries Division employee holds up a cisco caught as part of an inland lake survery. The survey has two purposes - to find out where cisco populations exist and to, potentially, serve as brood stock lakes should the DNR ever decide to re-introduce the creatures into other waterways.
