Like this male widow skimmer. This one looked like it had quite a bit of pruinose on the tale which is an indication that this was a mature dragon.
I was also a bit surprised to find a variegated meadowhawk. We do not see as many of this type then we do many of the other types of meadowhawks. When we do see them it is usually in the spring when they migrate north in large group or in the fall when they migrate east. Since this was late July it was a bit uncommon to see one.
Here is a better view of the variegated meadowhawk. The red color indicates that this is a male. The females are usually more of a yellow, mustard type color with a similar pattern on the abdomen.

So I headed off to Eden Prairie after work to explore the park and check out the mud flats for any possible shore birds. I was not disappointed. There were a lot of things for me to photograph. They even had a small mud flat with a few shorebirds like this killdeer.
Besides for the killdeer I also spotted a solitary sandpiper. You can tell that it is a solitary, as I learned later in August at the shorebird workshop which I attended, because of the white eye ring and the dark shoulder.
Solitary sandpiper often found alone, thus the name. They are unlike most other shorebirds in that they do not mind having vegetation around, so they are often found wandering small ponds.
The lesser yellowlegs, on the other hand, will usually avoid mud that is filled with greenery. They use their long legs to wade through the water looking for aquatic insects, and small fish to eat.
It is difficult to tell the difference between the lesser and greater yellowlegs. A lot of people look for a difference in size to tell them apart but this can be difficult when you have only one bird. In our shorebird class we were told to examine the beak of the bird, if it is two toned then it is a greater yellowlegs but if it is a single color, as this bird demonstrates, then it is a lesser yellowlegs.

After the banding I stuck around to help get ready for the Raptor Release that was held on Saturday. Pretty much my whole day Saturday was spent at Carpenter also. Between doing education at the hawk/falcon ring in the morning and the owl ring in the afternoon and sneaking away to take pictures off the release in the middle I was pretty busy.
I was so busy that I did not even get to go watch the nature centers program on reptiles and amphibians. Which is too bad because it may have given me some good info for today's post. As the summer went on I began to see more and more toads on my little journeys out into nature, so I decided to get a few pics, while I was out at the Bass Ponds back in July, to share on the blog.
I did a bit of research and I was surprised to find out that while all toads are frogs not all frogs are toads. You see the term frog is the scientific term of all frogs and toads. Toad is just a distinction or type of frog. So what makes a frog a toad? Well the main difference is that toads tend to have rough dry leathery skin typically filled with many bumps that resemble warts. This protective skin allows them to live further away from water then the other members of the frog family who have smooth skin. Toads usually also have shorter legs then other frogs and do not have teeth, other frogs have small fish like teeth.

Our educational birds out at the nature center, so that people can get a real close look at a live raptor, plus there will be a stage which will have music and programs from The Raptor Center as well as Carpenter Nature Center
There will be two different bird releases scheduled at 11:30 and at 1:00. These are birds that have been patched up down in the clinic and then rehabilitated and are now being released back into the wild.
These are pictures from the spring release. As you can probably tell from the expressions on the peoples faces the release is a wonderful experience and something, if you are in the Twin Cities area, I would definitely recommend.
In the afternoon I will be answering questions about Owls, like Samantha here, from 12:30 to 3:00. You can find more information on the event here and directions to Carpenter Nature Center here.

With the way that things are going in the US these days, especially with W in charge, I am pleasantly surprised to see the flag still flying every morning. The problems that we are seeing daily, due in most parts to the Bush administration, are much more dangerous then the bombs that Key witnessed back in 1814.

The eastern comma, pictured above, is one of earliest butterflies that we see each year. This is because they hibernate as adults. They spend the winter in a state of suspended animation in a crevice or hollow tree with their wings folded together and head down. In this position they avoid predators, while they are helpless, by appearing to be a dead leaf.
The red-spotted purple is actually a subspecies of the red-spotted admiral. These butterflies over winter as a Caterpillar in a rolled leaf of one of their host plants, which include willow, aspen, hawthorn, birch, poplar, basswood, juneberry, black cherry and apple trees.
The red-spotted purple resembles the pipevine swallowtail, which is toxic. This mimicry helps the red-spotted purple to avoid predators in the south where their ranges overlap. Up here in the north they are not so lucky and you can see this one has a few pieces missing from its wings.
Skippers are always tough for me to ID, I am still pretty new at butterflies, but I think that this may be a Delaware skipper. If anyone thinks that I am wrong please let me know in the comment section.

The twelve spotted skimmer is one of the most common dragons around. It is easily recognized, by the spots on the wings, and usually perches in the open making them easy to photograph. An added bonus is that if they flush when approached they will typically land back on the same perch or one near by.
The common whitetail male is also pretty hard to mistake. The wing pattern along with the white pruinose abdomen make them recognizable from a pretty good distance away. The female common whitetail looks a lot like a female twelve-spotted skimmer.
Widow skimmers are identified by the black and the white pruinose bands on their wings. The female widow skimmer only has the black band and does not get pruinose on the wings or abdomen.
One dragon that was not as common as the rest, that I was able to photograph that day, is the eastern amberwing. These small dragons are usually less then an inch long and prefer still or slow moving water.
This was a male eastern amberwing, you can tell because the wings are completely colored. The female amberwing has a wing pattern that is similar to the Halloween pennant, although they are quite a bit smaller.
The final dragon that I photographed was the four-spotted skimmer. This type of dragon can be found all over the globe including North America, Europe, North Africa and Asia.

So now that we are officially in fall I think that it is quite symbolic to post these pics of Halloween pennants that I took back in July at the Bass Ponds.
Halloween pennants have a very large range. They can be found from Southern Canada all the way down to the Florida Everglades. Males are orange, like the ones pictured in this post, while females are often more yellow in color.
Halloween pennants can be seen flying into about the middle of September, although I have not see any around here since the beginning of August, they are often active on colder days and when it rains.

So for today I have some more dragons from the Bass Ponds that I took in July. These are all meadowhawks. Meadowhawks are smaller, an inch to an inch and a half, dragonflies that are commonly seen mostly in fields later in the summer and into the fall.
There are at least 8 types of meadowhawks in my area. Several of the different types are very difficult to distinguish between unless you have them under a magnifying lens, especially juveniles and females.
Most of the male meadowhawks in my area are red in color. The exceptions to this would be the black meadowhawk, which is all black, and the band-winged, which can sometimes appear brown. The variegated is red but has an unique pattern and the Autumn meadowhawk is the only one with yellow-legs. The other four types are very similar. Females of all the species are usually a yellow orange color. My guess is that these were white-faced meadowhawks, especially the males.

So nothing fancy to start with, just a sky shot from Wood Lake Nature Center that I took while I was out yesterday.

The bright yellow color of a male goldfinch, in breeding plumage, stood out pretty well against a backdrop of green algae. The American goldfinch is one of the more common birds seen here in late summer. This is probably due to the fact that it is a late nester, nesting in late June or July when most other passerines are already done. Last year I got some great goldfinch shots on the thistle by one of the ponds, but the higher water level this spring prevented the thistle from growing back in that spot. So I have not had the opportunities to photograph goldfinch that I did last year. I also managed to get a pic of a great crested flycatcher. Usually great crested flycatchers are found at the top of the trees so I felt fortunate that this one came down so that I could get a pick. I had spotted them several times around the Bass Ponds so I am guessing that at least one pair nested in the area, wooded swamps would be prime breeding habitat.

Last fall as I got into my truck to come home from work I was stung on my arm by a yellow jacket. That was nothing though compared to this year. Yesterday I was on my way home from work, driving down the freeway when I felt a sharp pain in my right shoulder blade. Right away I thought that I had been stung but since I was on a freeway I could not stop. I leaned forward in my car seat and began to feel around for the culprit. I found nothing. I began to wonder if it was not just a nerve spike that sometimes I get as a diabetic, although usually in my arms, hands, feet or legs, especially since I had not heard any buzzing and I had been driving for over 15 minutes before the pain started. I began to relax and since the initial pain was diminishing began to slowly sit back. That was when I felt another shot of pain. Fortunately I was getting off the freeway and only a few minutes from home so I drove the rest of the way home leaning forward. When I got home I took off my shirt off right away and ran to the mirror to take a look. Sure enough there were 3 sting marks on my back but I still did not know what happened to the bee. That was until I shook my shirt out a bit and out fell a yellow jacket.
Maybe I should look into getting a bee keepers suite to keep me safe on my drive home.
In the fields I will just keep wearing jeans and a tee shirt because out there the bees, like the one above, are more interested in collecting pollen and nectar then they are stinging me. This bee is pretty loaded up with pollen, you can see the full orange pollen sack on its leg.
I was kind of excited to get these next couple of pics. Not because the red milkweed beetle is a rare insect that is difficult to find but instead because one of the guys that I work with went to college down in Austin, Texas and he is a big Texas Longhorn fan.
These beetles lay their eggs at the base of the milkweed plant. When the eggs hatch the larvae bore into the milkweed stem. They will spend the winter as larvae down in the roots. In the spring they will pupate and emerge as adults early in the summer. The adults usually can be found eating milkweed leaves, the toxicity of which make the red milkweed beetle a distasteful morsel to most predators.
The mourning cloak butterfly, on the other hand, is one of the few butterflies that over winters as an adult, in the northern portions of its range. This butterfly hibernates in suspended animation in a sheltered location over the winter. During this time the mourning cloak secretes chemicals like sorbital into their bodies which act as a natural antifreeze and prevent ice crystals from forming inside the butterfly.
This last picture is I believe a moth but I have no idea what kind. I am hoping that maybe some of the people over at bugguide.net, who I invited to come and take a look at the blog, can give me some idea as to what type of moth that this is. If you think that you might have an idea please post a comment to this post.
