RACCOON MOON

Mississippi Valley, Green Island Wetlands, Iowa

I left the Green Island Wetlands in the Mississippi Valley late last Sunday evening. My hope was to spot maybe a Short-eared Owl, which I had seen in this area before some years ago. This didn’t happen but instead the call from a Great Horned Owl echoed from the rocky bluffs that line the edge of the valley after sunset. I enjoyed it for a few minutes while sitting in the car with the windows down. Just as I was ready to leave I looked to the east and realized that I had missed the moonrise over the Mississippi River. It was still gorgeous and since the Sigma 150-600 S was still on camera, I used the long end of the lens for a compressed view across the wetlands.

I finished the book “Saga of the Sioux” just recently and learned that many civilizations, including native Americans, used a calendar based on the cycles of the moon. Some would call the one we see here “Moon of the Dark Red Calves”, others call it “Racoon Moon”. It makes sense, raccoons mate in February and amorous raccoons become especially raucous. Yep, let’s call this photo ‘Raccoon Moon’!

AFTER THE AMBUSH

Great Horned Owl, Mississippi Valley, Green Island Wetlands, iowa

Here is a photo from our second kayak trip last weekend, on Memorial Day in the Green Island Wetlands. At this time of the year it is nothing but pleasure to paddle this area, and always good for a surprise. During the heat of the summer algae usually effect the area and sometimes it is impossible to even maneuver a kayak through the thick green carpet.

On the way back to the boat ramp I suddenly saw a movement of a big bird on my left hand side. A Great Horned Owl took off from the dense grass on the dike, immediately attacked by some Red-winged Blackbirds. I made a U-turn, paddled a few meters back and saw the owl in the tree you see here. The interesting thing about this encounter is, that we have watched a Great Horned Owl in the same spot before, but several years ago. It seems they like a depression in the dike to perch and ambush for a potential prey. The photographer had a smile on his face while going back to the boat ramp… 😊

BALD EAGLE ON THE NEST

This Bald Eagle and its mate started building this nest already last year. It is only a few yards away from the former location of an old nest, a Great Horned Owl had used for several years. It fell finally apart two years ago. I have posted about the owls many times here in my blog between 2013 and 2017. Last year the eagles were maybe still too young to breed but it looks like they feed their first offspring now.

I went with my tripod into a swampy area about 50 yards away from the nest while none of the adult eagles was in it. I tried to hide between bushes and small trees and when the adult came back it didn’t look in my direction. It probably knew I was there but didn’t seem to mind my presence. These Bald Eagles are used to humans, there is a campsite nearby (of course, not used at the moment) and the access to a boat ramp and marina is not very far either. You can drive up very close to the nest, and some people may do because they don’t even know it is there.

It was sunny but still a little chilly today and after the adult bird arrived it seemed to feed and wiggled its body into the nest, probably keeping some young bird(s) warm. The partner was in another tree, closer to the Mississippi River, and hopefully came back with a good meal for the family…

OWL IN THE CAVE

Great Horned Owl, Dubuque, Iowa ------------------ 

Are you tired of seeing photos here in my blog taken in the wetlands along the Mississippi River lately? Well, today I have something different for you. Friends who follow my blog since several years know that at this time of the year I have reported about the breeding efforts of a pair Great Horned Owls down at the Mississippi not very far from home.

The bad news is, it isn’t happen this year. Great Horned Owls don’t really build their own nest but take possession of an old nest instead and maybe move a few sticks around. In this matter it was the nest of a Bald Eagle that the owl used for five years in a row. Well, rain, snow, and in particular wind have finally succeeded and the nest had fallen apart after the last breeding season. There are still a few branches and sticks up in the tree but it isn’t big enough to be the place for another generation of Great Horned Owls.

And here comes the good news. Thanks to a couple photography friends I learned about two other locations around Dubuque, Iowa with an active nest site. One is in a small cave and it isn’t easy to see mother owl back on the nest. I used the flash to throw some light into the hole but this wasn’t enough to make a difference, at least from what I saw on the display of the camera back. The solution for this photo was to expose all the way to the right of the histogram, but still making sure the surrounding rocks were not blown out. It is amazing how much dynamic range today’s cameras are able to capture and the RAW files can hold. Later at home in Adobe Lightroom I lowered the exposure of the rocks and lifted the shadows of the cave locally. And this revealed some detail inside the cave. I don’t know if there is an owlet deeper in the nest but will hopefully find out as time progresses.

FIVE RAPTORS

CYSCO, Harris’s Hawk, hatched in captivity in 1994, excelled as a falconry bird, and came to the Schlitz Audubon Center after retirement. ------------ 

It was fun at the 30th Annual Bald Eagle Watch in the Grand River Center of Dubuque yesterday. The event that celebrates the American Bald Eagle had a very good turnout with people of all ages. We had lots of good conversations with visitors at the information desk of the Dubuque Camera Club and the other participating organizations have been very busy as well. The highlight for many guests was without any doubt the live bird program, presented several times during the day by staff and volunteers of the Schlitz Audubon Nature Center, Milwaukee WI. The program was great education, not just for all the kids who got involved by Sara, who did a very good job of moderating it.

BARON VON SCREECH, Eastern Screech Owl, lost his right eye in a car accident.

It was allowed to take pictures, even with flash lights, but I decided to use just the ambient light for making some images of the raptors and the people who showed them to the audience. All photos were made handheld at f/4 between 1/20s and 1/40s. The ISO was cranked up to 1600. Shooting indoors is not my usual thing to do and dealing with white balance in very dim incandescent light had its challenges. The presenters moved around to give everybody a chance to have a close-up view of these beautiful raptors and the birds themselves move as well, with other words, not an easy task to get a sharp image.

CUTRIGHT, Peregrine Falcon, a retired falconry bird.

All seven birds of prey that were introduced to the audience (I only show five of them) are unable to make a living out in the wild for various reasons. Since I didn’t make notes (too busy fiddling with the camera 😉), the information about each bird under the photos is from the website of the Schlitz Audubon Nature Center. https://www.schlitzaudubon.org/education/raptor-program

TSKILI, Great Horned Owl, was stolen from her nest by a human who wanted her as a pet.

VALKYRIE, Bald Eagle, Was left by her parents earlier than normal. She did not have the hunting skills to survive in the wild. I like this photo because it shows the enormous size of an eagle, next to Sara, the main presenter of the program.

NOT LITTLE ANYMORE

Juvenile Great Horned Owl, Mississippi River, Mud Lake, Iowa ---------    

I made an early visit to Mud Lake this morning and came back with nothing. Looking for the branchling between all the leaves is like searching a needle in a hay stack. My photography friend Linda went later in the day to the same place and spotted the owlet successfully. I finally went back in the afternoon and found the young Great Horned Owl sitting on a branch in a large cluster of maple trees, the same spot Linda had described in an email to me. I’m very thankful to her for sending me the message.

I guess we shouldn’t call the owlet “little” anymore. It’s hard to believe it was only 37 days between the photos from today and my first shot of the young bird in the picture below. The click above was made when the bird turned its head and had an eye on our little dog Cooper, who sat quietly in the grass below. Maybe there were some thoughts about a future meal… Looking at its big claws leaves me without any doubts that this owl will be a great predator.

First sighting, March 28, 2017 (image cropped)

SPRING BIRDS UPDATE

The Male House Wrens sing and try to attract the females since April 21, 2017. Today a female wren inspected both floors at one of the nest boxes, and the male was probably praising how good of a place that would be for raising a family.

I like to photograph small birds any time of the year but spring is probably the most rewarding time. Most birds look at their best because it’s also mating season and during that time some species don’t care so much about the presence of a photographer because their mind is of course somewhere else. I love the light that we have when the first leaves just come out here in our woods. Yes, the sun can be powerful and make it harsh sometime but I love how crisp things appear under the spring sun.

Today new bird arrivals can be reported. We saw the first hummingbird at one of our feeders. The Rose-breasted Grosbeaks, males and females, are here since yesterday, and a male Scarlet Tanager was present today for the first time this season as well.

Chipping Sparrow, arrived already April, 21, 2017

So, what about the young Great Horned down at the Mississippi River? I was there Monday night during a rain shower and the nest was empty. It took me just about five minutes to find the owlet, now called a “branchling”, in a tall tree next to the nest. Other birders and photographers had sent me updates and photos today (thank you Linda and Kevin!). I will try to locate the owl tomorrow again, but with the leaves growing rapidly it’s going to be a challenge as always during an owls branch hopping stage.

Female Purple Finch, has still not left for their summer grounds up in northern Minnesota and Canada.

SPRING BIRDS AND MORE

White-throated Sparrow, near Durango, Iowa

I don’t mind to travel and it is an essential part of my job, but it is nice to be home again, especially at this time of the season. It’s getting green here in eastern Iowa, a little earlier than other years, and with the warm weather more birds arrive in our woods.

Yesterday I heard the wonderful sound of the male House Wrens for the first time this spring. He will wake me up in the morning during the next days and weeks by his melodious songs that hopefully will attract a female to one of our nest boxes.

There were several White-throated Sparrows in the grass below our bird feeders and they look never more beautiful than during this time of the year.

In addition a pair of Chipping Sparrows has arrived and unfortunately a Brown-headed Cowbird is around already. They like to lay their eggs into the nest of other birds and that doesn’t always go well for the offspring of the host bird.

Owlet, Great Horned Owl, Mississippi River, Mud Lake, Iowa

After being away for an entire week I had to go back to Mud Lake Park at the Mississippi and find out how the little owlet is doing. Other photographers kept me up to date during my time in California but since I watch this nest since five years I wanted to see it with my own eyes. The young owl has grown tremendously since I saw it the first time peeking out from under the mother’s feathers (Click HERE for the first photo). There is definitely only one owlet in the nest this year (last year we saw two) but it is so nice to see this episode continue.

MOTHER OWL

Mother owl did not show me her precious offspring this evening. She just sat on the nest and kept her owlet covered. I still don’t know how many owlets are in the nest but I talked to a camper, who had watched the owl since a while, and he told me he has not seen more than one.

As you can easily see the light had no character today. Yes, we had another day with mostly a deep overcast. I hope I can show you some more photos of a young Great Horned Owl soon.

ONE OWLET REVEALED

Nikon D750, Sigma 150-600mm / f5-6.3 DG OS HSM Sports Lens, tripod, Induro GHB2 gimbal head, Image cropped  -----------     

I had exciting thirty minutes at Mud Lake Park this evening. First I saw my first of the season Eastern Phoebe and Great Egret. There were also more than 80 Snow Geese heading north and a Brown Creeper worked its way up at one of the big trees. But the star this evening was the Great Horned Owl, revealing finally one owlet in her nest. Great Horned Owls are blind at birth and this little bugger didn’t have its eyes open yet. The female owl sat very high in the nest again and I wonder how many owlets were actually still under her body. I guess we will find out soon. Food seems not to be scarce. There was another gray-black feather ball at the edge of the nest, which I believe was a dead coot again that one of the parents had bagged.

UPDATE ON THE GREAT HORNED OWL

March 21, 2017  -------   

I have been several times at the nest of the Great Horned Owl at Mud Lake last week. As the two photos show the conditions can be very different from one day to the next.

Five days ago, March 21, great late afternoon light hit the nest. Mother owl didn’t change position at all. I recognized a ball of gray-black feathers on the right. This is probably the remains of some prey, possibly an American Coot, that she or the male owl had bagged.

March 26, 2017

This image is from today, March 26, 2017. The rain had just stopped and the owl still looks quite wet. She sits very high in the nest and that makes me believe that her offspring has hatched already some time ago. Here is a time table of my first sightings of an owlet at the same nest for each year:

2016: March 28, a second owlet March 31

2015: March 16

2014: March 28

2013: April 14

It looks like we may see some new life soon. I will try to visit the nest more frequently during the upcoming week.

Both photos were made with the Sigma 150-600, at 600 mm in DX-crop mode of the Nikon D750. This is the equivalent viewing angle of a 900 mm lens. I use the DX mode if I can’t go physically closer to my subject.

FIRST GLIMPSE

Great Horned Owl  ------------   

It looks like I show you the same image at this time of every year. Yes, a Great Horned Owl sits again in the nest at Mud Lake Park, just a stone throw away from the Mississippi River. 2017 is the fifth year in a row that the Great Horned has chosen this nest site. A couple other photographers have emailed me during the last days that they saw the owl and even the male was spotted in another tree (Thank you Linda and Ken!). Incubation takes about 28 to 35 days and is mostly done by the female.

 I was there yesterday afternoon but the bird was out of the nest. Today I used my lunch break to drive down to Mud Lake again and was even able to make a few clicks. Distance is always a bit of a problem and I used all my technical means to overcome it. First, the Sigma APO Teleconverter 1.4x EX DG was mounted between the Sigma 150-600 mm lens and the camera to extend the focal length to 850 mm. Second, the D750 was set to DX crop mode, which gave me the equivalent angle of view of a 1275 mm lens. I still cropped a little sliver on the right and top to keep a few distracting branches out of the frame. At that time of the day I had to shoot against the sun but a thin layer of clouds didn’t make this a big problem. Dialing in exposure compensation of +1 1/3 EV delivered the best results today. 

GREAT HORNED OWLS, EMPTY NEST

Owlet #1

I received an email this morning from another photographer (Thank you Ken!), telling me that yesterday he found the nest of the Great Horned Owls down at the Mississippi River empty. I replied that they might just be hunkered down in the nest because of the cold and wet weather we have at the moment. I just learned that owl feathers are not waterproof and rain can impact their ability to fly noiselessly, which can be trouble for an adult during the breeding season because they cannot hunt. Wet feathers lead also to a higher loss of body heat, which could be a thread for the owlets. However, I had to check it out during my lunch break today.

Owlet #1

As Ken already reported, I found the nest empty. It took me about half an hour until I discovered one of the owlets sitting on a big branch in a tree about 50 yards to the east from the nest. I took several pictures from both sides of the tree. Because of their ability to turn the head by 270 degree, owlet #1 had an eye on me most of the time without moving the rest of the body. The wind was blowing hard and getting an unobstructed view was a challenge because branches and leaves were swaying around the whole time.

Owlet #2,  All images: Nikon D750, Sigma 150-600mm / f5-6.3 DG OS HSM Sports Lens, tripod, Induro GHB2 gimbal head, Nikon SB 800 speed light, Better Beamer flash extender

I scanned every tree and branch around with my eyes in search for #1’s sibling. I just couldn’t find it. Ready to give up and go back to work I suddenly saw owlet #2 sitting upright in the tree next to me and only a few yards away. It was probably watching me the whole time while I tried to find it and laughed its head off…

It’s great to see that the young Great Horned Owls started branch hopping. Pretty soon they will learn to fly and they may stay with the adults until fall. The leaves in the tress grow rapidly and it will become very difficult to find the owlets again. I’m very happy that we can see two owlets, instead of just one, for the first time during the last four years.

WARM LIGHT AND THE LATEST ABOUT THE OWLS

Mississippi River, Mud Lake, Image made at 500 mm with Nikon D750, Sigma 150-600mm / f5-6.3 DG OS HSM Sports Lens

It’s a nice situation, I have made so many images recently , I just need to make up my mind what stories I like to tell first or maybe never. Sometimes the latest observations seem to be more important than the older pics… 

The backwaters of Mud Lake are the closest access to the Mississippi River for us, just ten minutes away from home. As you know, I watch the Great Horned Owl and their offspring during this time of the year at Mud Lake State Park and the photo below tells hopefully more I can even write about here…

Using the long lens for landscape photography may not be on every photographers mind. The compression of a scene, combined with gorgeous light, made me push the shutter release button this evening. The kiss of warm light during sunset is the right time to be there. The mighty Mississippi is behind this dike and the canal in the foreground is part of the Mud Lake backwaters.

UPDATE ON THE OWLETS

600 mm, 1/100s, f/6.3, ISO 320, flash fill

I know I have some friends out there, and as far away as South Africa, who like to hear about how our little owlets are doing. The weather has been kinda “crappy” during the last few days but I try to drive down to the Mississippi River after work several times a week in order to see how the young Great Horned Owls develop. For those who do not always read my blog, this is the first time during the last four years that the Great Horned Owl is raising two young owls. Any other year before was only one owlet in the nest.

Today it seemed again that the juveniles are in good condition and there was a brief moment when I saw both of them at the same time. The mother perched in trees nearby most of the time. She was at the nest only once while I was there. Mother owl went always back to the same trees and branches during the last week because she probably can observe the nest very good from all of her preferred spots. She must trust me, because she turns quite often her back to me and rather looks over to the Mississippi and perhaps watches for some prey.

600 mm, 1/100s, f/6.3, ISO 320, flash fill

Rain and dark clouds during the last evenings made the photography very challenging. There wasn’t an ounce, and not even a gram of nice light! In these conditions I like to master flash fill for my images, with all its quirks, like overexposed branches, red eyes, or just dealing with the settings in camera and in the flash. The missing contrast on an owlet’s head or body in low light makes it difficult to obtain always focus for a sharp image and not every picture is a keeper. I know, this doesn’t sound like fun but I really enjoy the process of trial, error, and improvement, and it makes me happy if at the end of the day there is an image on the memory card that tells the story…
