Animal 911


by Ben Bettterly, Wildlife Educator
Every Thursday, the North Lakeland Discovery Center hosts an EE program for 11-14 year olds called “Eco-Adventures. Eco-Adventures is an offsite program, where we explore local communities and natural area as part of a weekly theme.
Last week’s theme focused on Northwood’s wildlife; and so for Eco-Adventures we visited two wildlife rehabilitation centers in the area: Northwood’s Wildlife Center in Minocqua, and Wildlife Instincts in Rhinelander.   During our visit, we learned about ins-and-outs of wildlife rehabilitation, and found out what it takes to become a wildlife rehabilitator.
 The goal of any wildlife rehabilitation center is to help sick, injured, and/or abandoned (often young) animals, so that they can be released back into the wild as soon as possible.  It’s important to remember that animal rehab centers are not zoos, where animals are put on display for our entertainment. Instead human contact should be minimized as much as possible in order to avoid conflicts between humans and the “patients” when they are finally released back into the wild.  For this reason, animal rehabilitation centers are often limited, if not closed to the general public.
 Most animal rehabilitation centers rely purely on citizen donations for their funding; and animal rehabilitation doesn’t come cheap. For example, although we didn’t get to see them, Wildlife Instincts currently takes care of 10 abandoned bear cubs.  Each bear cub cost approximately $3,000 dollars by the time they are released.  This cost includes the price of food, and any medical or cleaning supplies that might be needed; and this can add up fast! That’s nearly $30,000 for bear cubs alone, and this doesn’t include the costs to take care of all the other animals that might need help such as foxes, otters, porcupines, raccoons, baby birds, etc.
 If you would like to support the Northwood’s Wildlife Center or Wildlife Instincts, donations are graciously accepted in the form of money or supplies (such as fruit, dog food, paper towels, etc.); however, I’d recommend calling first to find out what supplies are most in need.

Bat Survey Results Are In…….


by Licia Johnson, Naturalist

A few weeks ago I went out on a bat survey with DC member Ed Marshall on Squaw Lake in Lac du Flambeau.  We have received our results and map and it turns out it was an amazing survey!  Our map is below with all of our bat encounters.  A key is also below of the bat species we encountered.  The blue line on the map is our route we took, as you can see, it started out pretty slow with no encounters, but then we had bats the entire survey!  The majority of them being Little brown bats, a few Silver-haired bat, and we were excited to see the elusive Hoary bat on our survey.  Thanks Ed for taking the time to survey, looking forward to the next adventure!

Did You Know?


by Angie Ziobro, Environmental Education Intern

I have heard numerous jokes before about penguins and the north pole. For example: what do you call fifty penguins at the North Pole? (Really lost because they only live in the southern hemisphere). Fun jokes to keep kids thinking, yes, but did you know that this was not always true?

The Great Auk was a very interesting bird that lived off the Atlantic Coast until it was hunted to extinction in the mid nineteenth century. It was the only modern species in the genus Pinguinus. It was the similar appearance that what we call penguins today shared with the great auk which earned them the name “Penguin”. Modern day “penguins” are not related to the great auk however. Black and white like what people call penguins today, the great auk was flightless and a powerful swimmer.  Their song was not nearly as musical as that of our northern bird the loon, but like them their plumage was different as juveniles and in winter and summer.


Interlopers on our wetland invaders!!!


by Anne Kretchsmann, Waters Specialist


We are starting to supplementally feed the purple loosestrife bio-control beetles being reared at the Discovery Center by adding additional loose stems to each netted plant. Thanks to the rain we have gotten, we haven’t had to add water to the kiddie pools to keep the plants’ roots wet, which decreases our work. The plants are beginning to die at the top which signals that our release date is near!

Today I went to check on the beetles and feed them as necessary. I thought a few plants looked particularly sparse of leaves so I took a closer look. 



Much to my surprise, there were 3-inch long White-lined Sphinx Moth caterpillars munching away INSIDE the nets! I’m puzzled as to how they got into the nets which are designed to keep predators such as spiders OUT! While it’s good to know that sphinx moth larvae enjoy eating purple loosestrife, I went about trying to coax them to come out of the nets without letting the beetles out. It was a three-ring purple loosestrife circus!





“Greater familiarity with marshes on the part of more people could give man a truer and more wholesome view of himself in relation to Nature. In marshes, Life’s undercurrents and unknowns and evolutionary changes are exemplified with a high degree of independence from human dominance as long as the marshes remain in marshy condition. Marshes compromise their own form of wilderness. They have their own life-rich genuineness and reflect forces that are much older, much more permanent, and much mightier than man.” ~Paul Errington
