NATURE CLICKS #528 - GREEN HERON IN THE WETLANDS


Green Heron, Mississippi Valley, Green Island Wetlands, Iowa

I realized today that I haven’t been in the Green Island Wetlands since the end of May. A good reason to pack the long lens today and head out to this area of marshland, lakes, and woods along the Mississippi River. August is the time when herons and egrets are present, not always by large numbers, but with the lush green background of reeds, arrow heads, and water lilies the chances for a good shot are definitely there.

Green Herons are common and widespread, but it can be hard to see them. While their larger relatives, like the Great Blue Heron, can be often found in open parts of wetlands, the stocky and small Green Heron tends to be at the edges, in shallow water, or concealed in vegetation. The bird I found today balanced on a half-submerged tree branch in the water, surrounded by nothing than duck weed. As mucky as that may look to some, I think it makes for a nice background that separates the subject from the rest of the scene. As most of the time I use my car as a blind. The heron got a little nervous after I stopped but gave me about a minute to make some clicks before it finally disappeared in the jungle of cat tails and arrow heads on the mud bank in the background. The Green Heron wasn’t the only critter I had in front of the lens today, so please stay tuned for more to come…

NATURE CLICKS #519 - LONG-BILLED CURLEW


Long-billed Curlew, Badlands National Park, South Dakota

I have seen the Long-billed Curlew only along the coast in Southern California before, always during winter time, and it was a little bit of a surprise when I found them last spring in South Dakota. The Badlands have a lot of grassland to offer, with a few marshy spots here and there, and they are actually a perfect breeding ground for this large sandpiper. It is an uncommon bird and to my surprise we found them again a week ago at the same area of the national park. With their extraordinary long bill they are able to to reach ahead and pick up insects or to probe just below the surface of mud or soil. They also feed on burrowing wolf spiders in South Dakota, with the curve even matching the general shape of a spider burrow (source: sdakotabirds.com).

Distance was closer than last year but still not enough for an uncropped image. We watched them using the car as our “mobile blind”. In these wide open grasslands you have no chance to approach them by going on foot. There is also a lot of other birds and critters to watch and the last thing we wanted to do is disturbing any of them. Overall we saw five curlews and it was highly interesting to watch them foraging after their migration from the south.

COULDN’T ASK FOR MORE…


Trumpeter Swans, Mississippi Valley, Green Island Wetlands, Iowa

The biggest difference between my last visit in the Green Island Wetlands a week ago and today was the number of Canada Geese. Many more have arrived and spread wherever there was already open water. Most of the lakes and canals have still an ice cover but with warmer temperatures ahead of us this will change quickly. The bird migration has started and during the hour before sunset I saw hundreds, if not thousands, of geese flying upstream in the Mississippi Valley. The best sign that spring is probably just around the corner was the presence of seven Red-winged Blackbirds… YEEAAH!!!

Beside Canada Geese I watched and worked this pair of Trumpeter Swans with the camera. The light was lovely and while using the car again as my “mobile blind”, the swans acted like I wasn’t even there. It all came together in this photo. Both birds were very close together for a brief moment and their heads formed the shape of a heart. Couldn’t ask for more…

COOTS, DOING ME A FAVOR


American Coots, Green Island Wetlands, Mississippi River, Iowa

After not making a single click in over a week for several reasons I finally went out to the Green Island Wetlands yesterday evening. The water level of the Mississippi River is still rising and also in the Green Island area it is above normal.

It was windy and many of the ducks were hiding or at least not near the shore. Every year I have seen a large fleet of American Coots at this time of the year and I always was debating with myself how to make a picture that tells the story about their presence in large numbers. Quite often the raft of coots is stretched out and it is impossible to make this kind of a photo. This time was different and they did me a great favor. While I watched them through the binoculars in the distance, the whole fleet suddenly swam towards me and didn’t stop until they all were near my “mobile blind”, the car of course.

They were feeding and goofed around like coots do. Coots are kleptoparasitic, they’ll steal their meal from other birds if they don’t feel like hunting for their own food (source: iBirdPro app). Indeed, I have seen them arguing about water plants. Maybe that’s why it is always fun to watch this raucous and quarrelsome bird.

NATURE CLICKS #420 - HOODED MERGANSER


Male Hooded Merganser, Mississippi River, Green Island Wetlands, Iowa

As many times before I used my car as a mobile blind while watching for birds and taking pictures in the Green Island Wetlands yesterday. The Hooded Mergansers are usually very shy and take off quite often even before the car comes to a standstill. But love is in the air already and I watched several males competing for the attention of a female. This is our chance to make a successful click because they are distracted. The Hooded Merganser is the smallest of the three species found in North America. They find their prey underwater by sight. A third eyelid, the nictitating membrane, is clear and protects the eye during swimming. Beside aquatic insects, crustacians, frogs, plants and seeds, they feed on fish, capturing them with their serrated and hooked bill (see photo). More to come…please stay tuned!

NATURE CLICKS #403 - BLACK-CROWNED NIGHT HERON


Green Island Wetlands, Iowa

Only once before I have seen a Black-crowned Night Heron in the Green Island Wetlands and that was already five years ago. As hunters they have great endurance and can stand still for a long time until a small animal passes by. I saw this heron this afternoon sitting on this branch at the edge of the water. Using my car as a blind the bird didn’t feel bothered by me much and even closed his eyes a few times. I came back 90 minutes later in hope for some softer light and the heron was still on the same branch. I would call this true patience…😉

NATURE CLICKS #264 - HORNED LARK


It wasn’t an easy task to make the photos I show you today. There was a reason why I never was able to make any decent shots of the Horned Lark here in Iowa before. They live and breed in the open country, where no tree or bush can hide a desperate photographer ;-) I have seen them in a field just outside of the Green Island Wetlands many times before but never came close enough to make the image work. Yesterday evening I found a pair of Horned Larks foraging along one of the levees that separate the ponds in the wetlands. I maneuvered the car, which as you know serves as my mobile blind, several times in position. Many birds seem to accept the presence of a car quite often, while opening the door and getting out of it, may spook them away immediately. The two larks didn’t show much interest in me this time, but getting close was only one problem I had to overcome.

Most wildlife photographers are familiar (or at least should be) with using the peak of action, the short moment between movements, for the shot. It has been quite often best described with a bouncing basketball. The brief moment when the ball reaches its highest point and the speed is zero. This is the moment when you have your chance to make a sharp shot, no matter what your shutter speed is. The only way to make this work for your photography is trying to predict this moment a tad before and then use the ability of the camera to shoot several frames per second (the Nikon D300s does 6 fps). The Horned Lark gave me a hard time. Both were foraging, head down, and with high speed and intensity. Yes, there was peak of action but it occurred very irregular. Sometime the birds didn’t stop for more than ten seconds. Other times I thought I nailed it, but the lark had their eyes closed. Well, as you can imagine I had my good share of misses yesterday evening…

The good thing was that the light got better with every minute while working with the birds. You may ask why some of the grass and background looks black. The DNR (for my German friends: Department of Natural Resources, similar to Naturschutzbehörde) had a controlled burning in the area the week before. This is a way to keep prairie and marsh land in good condition. Wild fires have always played an important role for the health of these ecosystems and landscapes.
