Winter bald eagle watching events to held around the state

Eagle watching kicks off Jan. 14-15 in Prairie du Sac

MADISON - Sauk City and Prairie du Sac on the Wisconsin River will hold the 24th annual Bald Eagle Watching Days on Jan. 14-15, 2011, in partnership with event sponsor, the Alliant Energy Foundation. Cassville will hold its 17th annual Bald Eagle Days on Jan. 30-31 and Prairie du Chien will hold Bald Eagle Appreciation Day on Feb. 26.

Each winter, hundreds of bald eagles congregate along areas of the Wisconsin and Mississippi rivers where they feed on fish in the open water below dams. Wildlife officials say this is the largest concentration of wintering bald eagles in the lower 48 states, offering some of the best eagle viewing in the nation.

Volunteer spotters from the Ferry Bluff Eagle Council (exit DNR) counted 115 eagles on Dec. 5, 2010.

Wisconsin currently has approximately 1,145 territorial pairs of eagles, according to surveys conducted by DNR wildlife biologists.

In 1971 Wisconsin banned the use of DDT after scientists determined eagle numbers were dropping as the birds, impacted by DDT, failed to reproduce because their eggshells were weak. The bald eagle was listed as both a state and federally endangered species.

A major milestone was reached in August 2007 when the bald eagles were removed from the Federal Endangered Species Act's endangered and threatened species list. Wisconsin's large and successful population played a significant role in that federal delisting.

The Endangered Resources tax check-off option found on Wisconsin state tax returns gives taxpayers the option of donating a portion of any tax refund toward the protection and management of endangered resources in Wisconsin.

Many of the best eagle viewing destinations are featured in the Great Wisconsin Birding and Nature Trail guides available from the Department of Natural Resources.

Bald Eagle Watching Days at Sauk City-Prairie du Sac

The 24th Bald Eagle Watching Days will be held Friday evening and Saturday, Jan. 14 and 15. Events begin at 7 p.m. Friday with a live birds of prey show featuring hawks, eagles, owls and falcons put on by The Raptor Center from the University of Minnesota. Information is also available by calling 1-800-683-2453.

The raptor show will be repeated at 11 a.m. and 2 p.m. on Saturday.

Also on Saturday, Wollersheim Winery, the event's Conservation Partner, will offer Eagle White Wine tasting throughout the day. And, at 12:30 p.m., Wildlife humorist David Stokes will do a show titled "Fun Animal Adaptations." DNR staff will run kids activities and give talks on eagles in Wisconsin and eagle conservation efforts. There will be eagle tours throughout the day led by Ferry Bluff Eagle Council members and DNR staff. A complete schedule of activities (exit DNR) can be found on the Ferry Bluff Eagle Council Web site.

Open water below the dam on the Wisconsin River at Sauk City and Prairie du Sac is a customary winter gathering place for bald eagles. The Ferry Bluff Eagle Council maintains an overlook for viewing eagles, preserves habitat for eagles, conducts eagle programs, educates people on how to watch eagles yet maintain the bird's safety, creates educational material for schools and works with landowners to manage habitat. Council members also monitor night time eagle roosts during the winter.

Cassville Bald Eagle Days

The 17th Annual Bald Eagle Days Celebration will be held Jan. 30 and 31 in Cassville on the Mississippi River in Grant County. Every year hundreds of eagles spend the winter in the Cassville area where the birds can be seen along the village's waterfront.

Comments sought on draft study of health effects of silica in outdoor air

MADISON -- The public has an opportunity to review and comment on a draft study by state air quality officials on the possible health effects of exposure to silica in the outdoor air.

Silica is a compound made up of silicon and oxygen atoms and can be both naturally occurring and man-made. It is present in the environment in both crystalline and amorphous forms; only the crystalline form is of concern as an air pollutant. Ambient sources of silica include mining and rock crushing, construction, foundries, glass manufacturing, abrasive blasting, or other uses of sand and quartz.

"While health officials generally do not consider ambient exposures to silica, a known carcinogen, to pose a health risk to the general public, data from some states shows emissions from some industrial facilities could result in levels of concern for people living near the sources," said Jeff Meyers, an environmental toxicologist with the Department of Natural Resources Bureau of Air Management.

The study focuses on exposure to silica in the outdoor air. DNR has the responsibility and authority only to manage outdoor, or ambient, air quality and not indoor air quality.

The draft silica study [pdf; 2.3 MB] is available for review on the air management pages of the DNR website.

After reviewing the study, individuals can go to an online questionnaire to submit comments on the draft. Supporting data, studies or other relevant information can be submitted via e-mail or post to: Jeff Myers, Wisconsin DNR - AM/7, PO Box 7921, Madison, WI 53707-7921 or send them by e-mail to [].

Submissions will be accepted until 5 p.m. on Friday, Feb. 18.
