THE CRITTER AND A WORD ABOUT THE HABITAT

Striped Skunk, Upper Mississippi Valley, Green Island Wetlands, Iowa

A little hike deep into the marsh of the Green Island wetlands in the Mississippi Valley started with a nice surprise. With my eyes mostly up and looking out for birds, I almost stumbled over this Striped Skunk that was obviously in search for food. After we discovered each other the skunk kept searching, had still an eye on me ones in a while but wasn’t bothered much by my presence. I kept my distance, knowing that they can spray their musk, with its very powerful odor, several meters from the two scent glands they have around their anus. If you look at this beautiful animal it is easy to understand why it was one of North America's most sought-after fur-bearers.

I took a new lens I just had acquired for the first time on a hike and wanted to learn how it performs and how it handles in the field. The Nikon NIKKOR Z 100-400 f/4.5-5.6 VR S is only since a few days in my bag and using 400 mm focal length was perfect for this shot, keeping the distance and not making the skunk feeling threatened. I still cropped the picture a little bit because at the end of winter there is a lot of dead plant material scattered everywhere in the marsh and I tried to keep as much as possible out of the frame, especially in the foreground.

The second picture is a view across the marsh at Green Island, with the Illinois side of the Mississippi River in the background. This was shot with the same lens at 100 mm. It was quite cold during the last few days and most of the water was frozen again. The photo shows also the dilemma we face in many parts of the Upper Mississippi Valley. Floodplain forests along the Upper Mississippi River are experiencing mass die-offs, with thousands of trees lost due to prolonged, intensified flooding caused by climate change and altered river hydrology. These "dead zones" are compounded by invasive species, specifically the emerald ash borer.

I have visited and photographed the Green Island Wetlands since 2011 and even if I shoot mostly wildlife pictures, the landscape images from the past document some of the wildlife habitat loss we can see.

IN THE MEADOWS

Dickcissel, Dubuque, Iowa

Today I have a couple bird species for you that are threatened by habitat loss. I still find them every year in a meadow that can be easily turned into commercial use. It has been developed for this purpose but so far nobody has built anything there. I hope every summer it stays this way.

Both species are beautiful songbirds and even when they are hunkered down in the grass, like yesterday afternoon, we can at least hear them. I waited patiently and had a few moments when they left the grass, perched on a higher point, and posed for my camera.

NATURE CLICKS #449 - YELLOW-HEADED BLACKBIRD

Green Island Wetlands, Mississippi Valley, Iowa

It has been six years that I saw and photographed a Yellow-headed Blackbird in the Green Island Wetlands. There was a habitat, a smaller pond with lots of cattail plants, that went through a lot of abuse from construction related measurements by the railroad company that operates the neighboring railroad track. As a result the Yellow-headed Blackbirds disappeared from that location, the only one I knew where this species lived in this area.

Today Joan and I went back to the wetlands in hope to see the White-faced Ibis again. But they had moved on and were not found anywhere. Instead we saw two male Yellow-headed Blackbirds in this thorny tree while driving slowly down the gravel road on the dike. This gives me hope that this species is not lost for this area. Their call is a little different from that of the Red-winged Blackbird, which can be found in abundance. I will keep my ears and eyes open during this summer and maybe I can locate a new breeding ground somewhere between the reeds…
