Last night's class was about water in the landscape: ponds, streams, lakes and rivers. Part of the class was dedicated to learning about the different tests and indicators of pond health. In the photo above I'm holding on to a "thermometer on a stick" (no, you won't find that as a new food vendor item at next summer's state fair!) in an effort to determine whether the temperature of this pond is different at the surface vs. a depth of 60 centimeters (it wasn't, if you're curious).
As of last night, we have completed 6 Master Naturalist classes and have 3 more to go, plus the last class which includes graduation. May will be quite a busy class month as we have our regular Wednesday night sessions, plus 2 all-day Saturday field trips, and the Master Naturalist conference weekend event. AND, I still need to find some time in between Master Naturalist activities and working to get out and spot migrating warblers (finding a Cerulean Warbler is tops on my list this spring).
I wonder, what's the minimum number of hours of sleep I will need per night to still remain functional and do all the outdoor things I want to each day.......I think I'll be finding out in May!

Penny sez, "I approve of these sprouts being grown for my noms!"
A few weeks ago, after reading Jennifer's post about her new camera and seeing the wonderful pictures it took, I decided to take the plunge and purchase one for myself.
I've been wanting a smaller, more portable and less expensive camera than my big Canon PowerShot and this seems to be the perfect little camera. In fact, the first 3 photos on this post were taken by my new camera. Now I have a nice little pocket-sized camera to carry along on walks, to my naturalist classes, in my bag to work, or wherever there's a chance I might have that perfect photo opportunity (as long as I don't forget it!)

Yesterday, we had a little preview of summer here in southeastern Minnesota. It was a beautiful, sunny day and we reached a record high (for the day and the month!) of 92 degrees. It was a perfect day to get some more spring chores done outside and so I decided to get my purple martin gourds "furnished" and hung up on the gourd rack. The purple martins have arrived back in Minnesota and once again, I begin another season (Year 4!) of what is turning out to be the eternal quest to establish a purple martin colony in my backyard.
I have 12 gourds -- half are giant natural gourds and half are these plastic "Super Gourds." The plastic gourds are pretty much maintenance-free and will last for years, but I've found that the purple martins who do visit me and move into gourds definitely prefer the natural ones. Inside the bottom of the gourds, I put in a few handfuls of white pine needles that I've raked up from under my trees. This will give the martins a good base layer on which to build their nest and in addition to the drainage holes in the bottom of the gourds, will also help to keep their nests drier in the event of heavy rains.
Here are all the gourds in place. I've plugged the holes in the natural gourds and may have to do that with the plastic ones also if I notice that tree swallows, house sparrows or starlings are trying to take over the gourds before the martins arrive.
I really like using gourds for purple martin housing. They are so easy to care for and lightweight. If I was rich and had an established purple martin colony though, I would definitely get one of these Lonestar purple martin houses. They have huge nesting compartments with built-in predator guards inside each "apartment." I've visited a couple purple martin landlords who have these houses and they swear that it's the best martin house out there.

Now, to get back to the title of this post.......
This afternoon, I headed down to my sissy's to dig a hole in her front yard so she can get her new purple martin house put up, because they've finally made it back to Minnesota from Brazil! It was fun listening to a few martins flying overhead for distraction while I was trying to dig a 26" deep hole through the limestone buried under her front lawn. While I was digging, my niece was keeping me company outside and she happened to find this little birdie in the flower bed--an apparent casualty of a collision with the front window. As soon as she handed it to me, I knew it was a Brown Creeper.
I was saddened to know that this poor little bird's life had ended, but at the same time, it was quite amazing to hold this tiny creature in my hand and examine it a bit more closely. They're so well-adapted for survival in the wild. Look at this skinny, curved beak--a perfect tool that enables them to search in deep crevices of tree bark to locate a tasty insect or grub for nourishment.
Look at this bird's incredible feet--especially the huge hind toe claw! Perfect for gripping bark and "creeping" up the trunk of a tree in search of food.
I wish you could have felt how stiff and bristly its tail feather were. These stiff tail feathers also help to hold the brown creeper in place as it finds and extracts its food from tree bark crevices.
Its feathers were quite beautiful--even for a little brown and white bird. Look at the lovely markings on its wing feathers. I've only seen a Brown Creeper flying once and it was so fast I didn't even get a chance to notice its wings.
I was sorry this little bird had to die and I hope you don't think I'm exploiting the situation by showing these pictures in my blog. Even though it was dead, I felt honored to be able to hold such a tiny creature in my hand and be able to see up close the physical adaptations that enable this bird to live in the wild.

Because last week was quite nice, many of the farmers around here have started on their field work. We came across this old cemetery located some distance away from the road and in the middle of a cornfield. I don't remember ever seeing this cemetery before and once the corn gets tall, you would never be able to see it from the road.
I would have liked to walk over and look at some of the gravestones, but the ground was too muddy. I tried to find out more information on the internet, but this cemetery wasn't listed as one of the public cemeteries in Fillmore County. It looks very desolate on this dreary day, doesn't it?
Fly away vultures!
We continued heading south and eventually ended up at Goethite WMA. On one of the ponds near the road, we spotted a large number of Blue-Winged Teals.
While we were watching the ducks on this pond, I looked to my right and spotted another large flock of birds flying in the distance.

So far we have learned about Minnesota's biomes (we are in the deciduous forest biome), glaciers and geology and what effect they had on the big woods, management and identification of terrestrial plants (trees and shrubs), and last night's class on wildlife. I'm enjoying these classes and especially all the new things I'm learning.
Those dang starlings! It took them almost 3 months to figure out how to get to the suet log inside this cage. I don't know if it's just this one bird, but when I got home from work this afternoon, there was a starling all the way up inside--with one foot braced on the suet log and one on the cage. I was hoping they'd never figure this out, but this is one smart bird. Now I'm going to have to attach a pie plate to the bottom of the log and cut off that access. The only bad thing about that is the hairy woodpeckers will also lose their access to the suet log. Crap!!

I was even more surprised when I got home to find that there was also a pair checking out a woodpecker cavity in the dead birch tree in my front yard! (The downy woodpeckers excavate these holes, but to the best of my knowledge, they have never used them for nesting.)
I had seen house sparrows going in and out of this hole earlier in the winter, so I hope the bluebirds can keep them away. It would be so amazing if they nested here because this dead tree is right outside the bedroom window and it would be extremely cool to wake up to the sound of bluebirds singing every morning!
And here's Mrs. Bluebird waiting for Mr. Bluebird to come out of the tree cavity.
And here's one more short movie, because I just can't get enough of these birds!

We're still enjoying some pretty decent spring weather and although today was overcast and not quite as warm as yesterday, I decided to go out this afternoon and do some more yard clean-up chores. Last week I burned off part of the wildflower patch and since it wasn't very windy and fairly cool this afternoon, I decided to finish burning the rest of the patch. It's been quite a few years since I burned the entire patch, so it was way overdue.
I had the garden hose ready and watered down the grass around the trees and shrubs within the area to be burned so that none of these would get burned. In the center of both pictures you can probably make out my big ol' brushpile. The bunnies and possums live under it and the birds use it to escape from the Cooper's hawk, so I took special precautions to make sure that the brushpile didn't burn either.

Goethite WMA is south of Spring Valley, Minnesota (about 30 miles from my house). After I turned off the main highway, I traveled past several ponds close to the road, and managed to spot these Greater Yellowlegs at one of the ponds.
A couple more miles down the road brought me to my final destination. I didn't remember this area being so large!
Here's the first view I saw after parking and getting out of the car -- a big pond that was an open pit iron ore mine back in the 20th century. No waterfowl on this pond, I guess I must have missed most of the migrating ducks and geese that Troutbirder saw last week when he was down here.
Since I was wearing my boots that were made for walking, I took off down a fairly well traveled trail to see what kinds of birds and other cool stuff I could spot. While watching a pair of Eastern bluebirds, I happened to notice this sweet little goldfinch nest that had survived the winter. Isn't it neat how they can fit their nests into little trees like this?
Oh cool, what's this? It looks like a beaver dam on one of the ponds. You probably can't tell from this picture, but the dam is almost 5 feet high and if you click to enlarge it, you might be able to see just a little bit of the pond on the other side (right in the middle).
Shee-it! That water was WAY DEEPER than it looked -- and really COLD too! Oh well, I had my wool socks on, so at least my foot didn't get cold (and my pant leg was just about dry by the time I got home!)
So here's the beaver dam from the other side, with the pond right at the top edge. I didn't see evidence of any recent beaver activity, so I'm not sure if they're still present in this area, but it was nice to see that their sturdy dam is still intact.
I was glad I made the crossing to this area because while I was over there, I had the great fortune to spot two sandhill cranes walking around in the tall grass. I tried to sneak up on them to get some pictures, but had no luck with that. I did however, spot this large raptor (juvenile red-tailed or juvenile bald eagle?) with a red-winged blackbird monitor nearby.
I continued to wander around this area looking for birds and I hoped I was traveling in a big circle and would eventually find my way back to the road. After coming out of a little woods, I was relieved to spot the car right where I had parked it (of course, that huge pink arrow in the sky was a big help too!)
Now that I knew for sure where I was, I could continue with my explorations and not worry about being lost. I watched this Canada goose for awhile....I thought maybe it was injured or something because I've never seen a goose lay its head down in the water like this, have you?
Because Goethite WMA was once an iron mining area, you can still see chunks of iron ore while walking around here. Some are small, like this piece I found on the trail.....
Back at the car, I watch a black-capped chickadee checking out a possible new home across the road.
