Bald eagles in Wisconsin, and across the country, were once on the verge of extinction, but they’ve made a comeback through conservation efforts. Nests for these distinct birds are now found in 71 of Wisconsin’s 72 counties, typically near a water body such as the Mississippi River. In just the last year, numbers in the southeastern part of the state have increased by 27 percent.
“Eagle flight” surveys are conducted via plane by researchers, who are looking to see if known-nests are active and incubating. Bald eagles are known for having one of the bird world’s biggest nests so they can be easy to spot and eagles tend to return to the same nest year-after-year.
We sat down with Rich Staffen, a zoologist and conservation biologist working with our Natural Heritage Inventory to learn a bit more about these raptors, and Carly Lapin, a National Heritage Conservation ecologist, about how Wisconsinites can help with continued conservation work for eagles.

TRANSCRIPT
Intro Voice: [00:00:00] Welcome to Wisconsin DNR's Wild Wisconsin - Off The Record podcast. Information straight from the source.
Katie Grant: [00:00:12] Welcome back to another episode of Wild Wisconsin - Off The Record. I'm your host DNR's digital media coordinator, Katie Grant. Imagine it's a warm summer day. You're sitting on the edge of the lake relaxing. Maybe reading a book. You look up long enough to notice an eagle soaring across the sky and it seems everyone around you is also staring in awe. There's something about seeing an eagle that just makes everything stop. Bald eagles in Wisconsin and across the country,, used to be rarely seen, and we're on the verge of extinction, but they've made a comeback here in Wisconsin, and nests can now be found in 71 of our 72 counties.
In just the last year, their numbers in the southeastern part of the state have grown by 27%. We asked our followers on Instagram what they wanted to know about this captivating bird, and you guys sure came through with the questions. We sat down with Rich Staffen, a zoologist and conservation biologist working with our Natural Heritage Inventory to learn a bit more about these raptors.
So sit back and listen in.
Rich Staffen: [00:01:22] So I am a zoologist and conservation biologist for the DNR and the Natural Heritage Conservation program. Formerly, we were the Endangered Resources program. So I work within a, um, section of the Natural Heritage Inventory. Okay. So as the name implies, we do a lot of inventory or surveys throughout the state, and I focus largely on vertebrate species, so birds and raptors, reptiles and amphibians and mammals, largely small mammals, and doing surveys, um, or inventory around the state on public lands, um, to help identify where some of our rare species are located.
Their distribution throughout the state, um, how they're doing, and then identify some really important or significant areas, um, for rare species on, um, state lands, state forests, state, natural areas, state parks. So all this information gets built up into the Natural Heritage nventory database, which I help, uh, add records to.
Katie Grant: [00:02:30] Okay.
Rich Staffen: [00:02:31] And that's the, like the central location for rare species and high quality natural community data that helps, um, researchers and managers and, um, is the resource for environmental review to minimize impacts on rare species throughout the state.
Katie Grant: [00:02:49] Okay. So you spend a lot of time outdoors then?
Rich Staffen: [00:02:52] Yeah, I get to spend, luckily, probably about maybe a quarter of my time, maybe a little bit more out in the field.
I'm doing surveys and monitoring, um, rare species. And then also, like I mentioned, um doing some, um, adding information to this rare species database, so mapping and GIS. And entering data, tabular data for the database as well.
Katie Grant: [00:03:17] All right. What... I know you work with a lot of different things. What is your favorite thing to get out there and look for?
Rich Staffen: [00:03:25] Yeah, that's, people ask me that. That's a tricky question. I mean, I think I've started with birds and and raptors. Um, so that's still holds a special place for me for sure. But I am doing a lot more work with, um reptiles in particular... so snakes, I do a fair amount of work with some of our rattlesnake species.
Primarily. We have a state endangered rattlesnake, the Eastern Massassauga rattlesnake. Um, and then some other, um, uncommon or rare snakes and do some turtle work. So I enjoy that a lot. And then I've, um, started to get into some small mammal work, um, for state properties and it's always kind of exciting cause it's kind of a new um realm for me to learn more about small mammals and see some of those,for the first time.
Katie Grant: [00:04:12] Something a little different.
Rich Staffen: [00:04:13] Yeah. Yeah . It's kinda fun.
Katie Grant: [00:04:15] So you mentioned working with raptors, um, and obviously we have you here today to talk about birds and eagles in particular. What, what first got you interested in eagles and raptors and that whole world.
Rich Staffen: [00:04:31] Yeah. I think, um, from the bird perspective, when I was in getting my degree in wildlife biology, I spent a summer working in the Great Smoky Mountains National Park, and that was my first kind of initiation to bird work. So I spent the summer, um chasing birds down there and um watching how they nest and how productive they are and nesting down there for a PhD student at the time. And then once I got my position here with the Wisconsin DNR and focusing in the Natural Heritage Inventory realm, I kind of, um, a lot of the work that we do again, is for rare species. So we have several, um, rare, uncommon raptor species that I, um, got to work with, um, including the red shouldered hawk, bald eagles, northern goshawks... so forest raptors... peregrine falcon, um, so several uncommon raptors.
So Irkinda got my feet wet working with some of those, um, rare Raptor species. And then, um, at the time bald eagles were um still federally listed until 2007. So we were, um, tracking how they were doing, of course, and doing the, um, aerial surveys that we still do to this day, which is one of the longest running Eagle surveys in the country.
Katie Grant: [00:05:51] Here in Wisconsin?
Rich Staffen: [00:05:52] Yeah. It's over 30 years. Um, that's been going on. So it's been going on for a very long time. Um, and we got some great information and have kind of been able to monitor how the population has recovered. So, um, and then kinda got on board with that mostly through the data side of it. Um, keeping track of, um, the records of bald eagles for rare species database. And then in the last, uh, three or five years, kind of getting, um, to do some of the eagle flights as well, eagle and osprey flights in southwestern Wisconsin. So...
Katie Grant: [00:06:27] Very cool.
Rich Staffen: [00:06:27] It's been really fun.
Katie Grant: [00:06:28] Yeah. It sounds like it. While we're kind of on the topic, why don't you tell me a little bit about surveys? How do they w...
