Ranger River Walks

a peregrine We have a new activity we're offering this summer at the Mississippi National River and Recreation Area called Ranger River Walks.  We meet at different parts of our park and show whoever is there around.  There's an asterisk next to the list of parks that denotes if it's a specific birding ranger walk, but if I'm leading any of them, they will automatically be a birding walk, I can't help it.  I did one yesterday at Lock and Dam 1 to see the peregrine nest box (above).  Unfortunately, the nest failed, but the adults are still hanging out.

The lock and dam is a fun place for some light birding anyway.  There are usually herons and waterfowl hanging out right under the platform and it's fun to look right down on them, it's your chance to see those great long heron toes.  The dam is a great spot for them to go fishing, you'll also see cormorants hanging out around the dame too.

a night heron

This poor black-crowned night-heron was trying to fish but the great blue herons kept chasing him off.  It finally found a spot around some rocks to fish in peace, but just another fun bird that you can find in our very urban park.

I think the next ranger walk I lead is on June 24 at Minnehaha Falls if you would like to come along.  Maybe we'll find a merlin, they've been around there in the past.

a bunting

After the Ranger Walk, I headed over to Crosby Park to help get things ready for the bird banding that we'll do this Saturday at the BioBlitz.  There were indigo buntings all over the place, if you've never seen one or had a good look at one, you'll get it this weekend if you show up.  Above is the same bird that I got the video of yesterday.

While I was there at about noon, I head some barred owls hooting and a black-billed cuckoo.  I doubt we'll get those in the nets, but still there are some great birds to be found in that park.

And I leave you with a video of that peregrine falcon preening:

The Upcoming Minnesota Bioblitz

This year's Minnesota Bioblitz is at my National Park (The Mississippi National River and Recreation Area) in the Crosby Farm Park area. The Bioblitz is a 24-hour survey where the public can help scientists find different plants and animals.  The event is coordinated by the University of Minnesota Bell Museum of Natural History, is free (except for the river boat ride)  and open to the public. Here is the current schedule of events--All events are free of change and open to the public until otherwise noted:

Friday, June 12 5 p.m. BioBlitz Kick Off 8:30 p.m. Night Creatures Ramble 9:30 p.m. Insect Survey*

Saturday, June 13 6 to 8 a.m. Bird Hike (I will be leading this) 8:30 to10 a.m. Bird Cruise/Bird Survey on the Jonathan Padelford. Tickets are $15; regist ration is required. 8 to 11 a.m. Bird Banding (led by Mark Newstrom & I'll help) 8 to 9 a.m. Mammal/”Herp” Survey* 9 to 10 a.m. Floodplain Forest Foray 10:30 a.m. Fun with Fish—Electro-fishing Demonstration* 10 to 11 a.m. Disappearing Waterfall Walk 10:30 a.m. Fun with Fish—Electro-fishing Demonstration* 11 a.m. to noon Mussel Madness

*  These programs include special activities for children involved in the  National Park Service’s Junior Ranger program.

Every year BioBlitz attracts hundreds of families and scientists from around the state who use sonar detectors, bug lights, live traps and laptops to count and chronicle an area’s floral and fauna. Volunteers of all ages work alongside biologists to collect plants and insects and live-trap animals, which are identified before being released back into the wild. Collection stations and inventory “leader boards” will be set up inside the Padelford which will be docked at Crosby Farm Park, the BioBliz base-camp.

This year’s BioBlitz will feature a Saturday morning birding cruise aboard the Padelford as it makes its way to dock at base-camp. The cruise leaves St. Paul’s Harriet Island at 8:30 a.m. and arrives at Crosby Farm Park two hours later. Tickets are $15 and shuttle service is included, click here to make reservations.

I noticed Padelford offers a Sunset Dinner Cruise and a Margaritas on the Mississippi Cruise...maybe we should do that for a Birds and Beers this summer?

The Bioblitz should be a great time, Mark and I scouted the park for net locations and I think we saw at least six male indigo bunting on different territories and heard broad-winged hawks calling.  This is also the park where I suspect a pileated woodpecker is nesting.

Taking Interpretation To The Streets

I work part time as a ranger for the National Park Service at the Mississippi River Visitor Center.  The visitor center is located in the lobby of the Science Museum in downtown St. Paul, but it's right on the Mississippi River.  Yesterday, I was working the closing shift and things were rather quiet.  I was working on some promotion for the upcoming Minnesota Bioblitz (which is going to be loads of fun, if you are in the Twin Cities, you should try to come for part of it--bird banding, river boat rides, electro fishing, reptile finding--something for everyone!). I noticed that it was getting cloudy, I turned to face the window to see what the weather was doing and as soon as I did, a peregrine flew low right along Kellogg over the library.  I watched it corner and waited or it to pop up over the building.  It never popped.  I knew it must have landed and would be perched fairly low.  Since I had been out birding before I came into work, I just happened to have my scope and camera with me and made the decision to interpret the falcon on the streets.

scope

That dark spot in the middle of the red circle is the peregrine.  It was very visible to the naked eye.

interpretation

A woman with a badge and big scope is quite the attention getter and many people came over to see what I was watching, which I happily shared with them through the scope.  A cab driver even made one heck of a U-turn to pull over to see what the bird was.  With the Mississippi River right behind us, it was easy to talk about why the bird was here.

peregrine

Looking through they scope, you could see the bird was in immature plumage.  I think she was hatched last year and probably was perched low (for a peregrine) because the resident pair would be nesting and don't take kindly to other peregrines sharing their hunting territory.  She preened and relaxed or awhile and ended up staying after dark.  She was still there when I closed for the night.

When people weren't on the sidewalks, I would go back into the Science Museum and wait for families who looked like they were leaving and say, "Psst, hey kids, want to see a wild peregrine falcon?"  No one said no.  My favorite group of kids wouldn't leave.  Their mom kept saying, "C'mon kids, it's time to go eat." However, the kids would take turns and say, "Hey, mom, just one more look, one more look."

Unlike the programs at The Raptor Center where most kids already know so much about birds they could practically give the program for you, the people just randomly walking by knew very little about peregrines or birds in general and it was fun to just say, "Hey, check it out, that's the fastest bird on the planet right there." And they seemed genuinely surprised.  I even helped a few people take photos with their iPhones.

I took a quick video of the bird...it's also kind of a fun way to demonstrate digiscoping.  And, I know I call the bird a "guy" in the video, but based on size, this has to be a female:

Mystery Nest

st-paul-peregrine-2 Boy, spring hormones are kicking in with the local peregrine falcons. I was walking from the Mississippi National River & Recreation Headquarters to the visitor center in downtown St Paul when I heard a familiar "Per-chup per-chup per-chup." Sure enough, the local breeding peregrines were circling and diving towards each other. It didn't look like territory battle, but more display and pair bond reaffirmation.

While I was at headquarters, a co-worker showed me a nest that had been collected on one of the islands in our national park near the Twin Cities metro area.  She found it last fall and when she first described it to me, I couldn't figure out what was going on.  It was a nest that was covered with cotton, but had a perfectly round hole on top.  What could that be?  I finally got to see it today.

double-decker-nest

At first glance, I realized that it was two nests, one stacked on top of the other.  This could have been done for a couple of different reasons, maybe a bird decided to build on a nest from the previous year? Or, I wondered, if the bottom nest started as maybe a warbler nest and then a cowbird laid an egg and the warbler decided to start over with a new nest on top?  I asked my co-worker if I could pull them apart and she seemed hesitant, but then said it was okay.

hidden-eggs

I pried them slightly apart and low and behold, there were two eggs hidden in the bottom nest.  Now, here was the question, are these cowbird eggs or are these the original nest builder eggs?  For the non birders who read this blog, brown-headed cowbirds do not raise their own young, they are a parasitic birds and lay eggs in other species' nests.  Sometimes you will see a small bird like a yellow warbler feeding a brown bird twice its size.  That is a young cowbird that has been raised by unknowing birds.

mystery-egg

I set one of the eggs on a ruler to measure it.  It looked to be about 5cm long.  I'm going to have to go home and look up the length of cowbird eggs vs warbler and sparrow eggs.  Based on where the nest was found, the most likely candidates for who made it would be song sparrow, yellow warbler, or common yellowthroat.  I'm not that great at nest id and I don't have any of my nest books with me.  Are these the nest builder's eggs or are these cowbird eggs?

mystery-nest

We looked into the nest on top where there was some cotton looking material and a hole. At first I wondered if a mouse had covered up the top cup and used the double nest as a home, but then realized that the cotton looking layer was  mostly likely the lining for that nest, put in by the birds that built it.  The hole was probably made by a mouse or rodent, perhaps it could smell the eggs underneath and went to investigate? Perhaps there were originally more than two eggs and the mouse ate some (then decided they were old and nasty and not worth eating more).

So many questions left unanswered with this mystery nest, but quite a few stories in there as well.

My Life As A Part Time Park Ranger

So, in April, I got a part-time job as a park ranger for the Mississippi River and it is a great time! I work primarily at the Mississippi River Visitor's Center at the Science Museum of Minnesota but I do get a chance to get out in the field. Last week, a group of staff went canoeing along the Vermillion Bottoms. What a joy to canoe in spring and get to know some of the people who work for the parks like the Historian, Botany Bob, and Rock Girl (nicknames all based on their areas of expertise--although Non Birding Bill said that we sounded like some sad band of super heroes: "The Historian and Birdchick canoe the river using their magical interpretation skills to save the people!")

I had a great time, the birding was fantastic. I couldn't really take my digiscoping equipment in the canoe, but still could watch the birds. Above, you might notice a bright yellow spot in that pile of brush--that was one of about eight prothonotary warblers we saw. You can't really tell it from the photo, but we could see them very well with the naked eyes. We heard parulas (and other warblers), had a flock of caspian terns fly over, saw one sandhilll crane, lots of eagles and I was totally surprised to see a flock of common nighthawks hawking for insects above our heads. I figured these normally nocturnal birds were mid-migration and very hungry.

We stopped for bit and had lunch along the river. We were there at least thirty minutes and a few of us snuck off into the woods to...see a man about a horse. As I was working my way back, I heard a strange noise right about where the above photo was taken. I pished a few times and a few seconds later a HUGE turkey hen burst out of the grass...almost causing me to relieve myself on the spot. All of us should have noticed a turkey lurking in the grass during lunch...unless she was totally hunkered on a nest. I walked over to where she burst forth:

There were the eggs. Poor thing must have been terrified when we pulled up our canoes and started eating. We had finished our lunch so we packed up as quick as we could and left to give her a chance to come back to her nest of fourteen eggs.

You do see quite a bit of litter along the river, one of the most disturbing piece we found was this two liter bottle of 7-Up filled to the brim with used hypodermic needles. EW!

Canoeing isn't the only thing I've been up to. The week before the canoeing, I got to go out and follow along with some of the eagle banding happening along the Mississippi River.

Even though the bald eagle is off the endangered species list, it's a good idea to keep tabs on them. Because they are so high on the food chain on the river, the researchers are using the eagles as an indicator species--if something is affecting them, it's eventually going to affect the humans. The birds all have a bit of blood drawn that's DNA tested and also checked for pollutants. Because the research is still going on, I can't give all the details at the moment...but it does make me want to be a bit more choosy about what part of the river I would eat fish from.

Check out those eagle toes! I will say that it was fun to work with big birds in my banding comfort zone as opposed to those teeny warblers.

Professional tree climbers from out west were brought in to get the eagle chicks out of the nest. It was way cool to watch them work. They used a crossbow with an arrow and string attached. Once the arrow made it over an appropriate branch, a climbing rope was added and then the guys would climb the rope into the trees. It was impressive to say the least.

It was interesting to notice the animals living the trees with the eagle nest. One tree had an oriole nest a few feet away. Above, a guy from the DNR was measuring the circumference of the nest tree when he shouted, "Hey, there's something nesting in here...and it's furry." He didn't want to stick his hand in, so I gave him my camera to stick in the hole and snap a photo:

At first, we weren't sure what they were. I wondered if they were otter, but if you look at the back paws, that gives them away. Do you know? They're baby raccoons--prey, right in the base of a tree with an eagle nest!

There have been requests to see the park ranger uniform:

If you're thinking "Wow, a badge and a cool hat--that's gotta be fun!"

It is.

If you're at the Science Museum, stop in and say hello.
