NATURE CLICKS #572 - EASTERN BLUEBIRDS

Male Eastern Bluebird. Their vibrant blue feathers during breeding season are easy to spot between the trees, even under low light conditions.

Shortly after our return from Oregon I saw a pair of Eastern Bluebirds inspecting a nest box I have built for this particular species a couple years ago. I saw both, the female and the male last weekend again and my hopes grow that they may take possession of the place and built a nest. The biggest competitors are the House Wrens and the first one has already arrived. Last year a male wren stuffed a lot of loose little twigs and branches into the hole and as I later found out, all on top of a bluebird nest. The wrens are much more aggressive and the bluebirds had no chance. We have several bird boxes for the House Wrens but they have their own mind and choose whatever place they like the best. Since we had a breeding pair of Eastern Bluebirds in 2020 in another nest box I still hope it will happen again.

The colors of the female are much more subdued. After a male has attracted a female to his nest site, the female actually builds the nest. Both parents feed the brood.

SPRING ENCOUNTERS

Cedar Waxwing

After quite a bit of traveling lately it feels good to sit on the porch in the morning with a cup of coffee on the table and spend some time behind the camera. We had some really warm days in February already but this was the first weekend that felt really like spring, with lots of sunshine and very warm temperatures. During the last couple of weeks, after our return from Oregon, several migrating birds have arrived, some earlier than usually. Among them are Eastern Phoebes, Ruby-crowned Kinglets, Chipping Sparrows, Eastern Bluebirds, and this morning the first House Wren inspected our nest boxes. At the other hand, a couple species are still present that normally leave our woods and move further north as soon the temperatures are above freezing, like Dark-eyed Juncos and Purple Finches. A trend we have seen already during the last three years and that makes me wonder if we experience a change in migrating behavior due to much warmer winters. I make notes every spring since 2007 beside recording first sightings of the season with the camera.

The most colorful bird I had in front of the lens today was this Cedar Waxwing. They are supposed to be here all year long but we don’t see them very often during the cold season. Their appetite for cedar berries during the winter gave them obviously their name. Since we have red cedars here on the bluffs above the Little Maquoketa Valley, the waxwing’s appearance is not really a surprise.

LIFE IN THE TIDE POOLS

Sea anemones

I was at a conference in Dallas, TX this week and a busy schedule prevented that time was spent behind the camera. Luckily I still have a number of pictures from our trip to the Oregon coast I like to share with you.

It took a few days before we had the conditions that we were looking for to explore the life and beauty in the tide pools. It needs of course a low tide at a rocky beach and the colors can be revealed if the sun shines at least a little bit. A polarizing filter in front of the lens works great for eliminating most of the glare on the water and for revealing the colors on mussels, clams, sea anemones, crabs and whatever else we found.

A NOISY BUNCH (SEE THE VIDEO)

California Sea Lions, Newport, Oregon

Back to our trip along the Pacific coast in Oregon. You have not seen Newport if you didn’t see the sea lions in the harbor. From late August through early June adult and juvenile male sea lions can be seen on the docks of the Newport harbor. The females stay in California waters all year around. During the summer months male sea lions migrate south to join the females for their breeding season. (source: information board at the Newport harbor)

You don’t need a map to find them at the harbor, just follow the barking noise. There is a constant pushing and shoving going on while competing for space on the docks. Feel free to click the video below to hear and see the noisy bunch.

UNTIL THE LIGHT WAS GONE

Greater Yellowleg, Mississippi Valley, Green Island Wetlands, Iowa

The weather this week was not very pleasant, with temperatures around the freezing point, rain, even a little bit of snow, and almost no sun in the sky.This changed finally today and I could realize my plans going for some wildlife shooting to the Green Island Wetlands in the Mississippi Valley this evening. All the clouds disappeared and the best thing was that the air stayed relatively cool, means it was clear and the often feared heat shimmer above the surface of the wetland didn’t occur. With other words, great shooting conditions.

I saw lots of ducks, mostly Wood Ducks and Northern Shovelers, of course Canada Geese, Bald Eagles, the local Northern Harrier, and a small number of Tree Swallows. But the most exciting encounter were three Greater Yellowlegs. These migrating sandpipers were feeding in the shallow water at Green Island but they were quite a bit away. By attaching the 1.4x Teleconverter to the lens my focal length went up to 850 mm. This seemed still not close enough and I set the camera to ”crop mode”, which uses a smaller part of the sensor only, but gave me the equivalent of 1275 mm focal length. I thought without heat shimmer, as often present at this time of the year above the water surface, I can try it and had indeed quite a few sharp images.

Before driving back home I headed to the gravel road on the westside of the wetlands and found another Greater Yellowleg foraging in the water that covered the field below after the rain. The sun was setting behind me and the bird still searched for food and flew away only after all direct light was gone.

YAQUINA HEAD

Yaquina Head Lighthouse, Newport, Oregon

One of my favorite locations we visited at the Oregon coast last week was Yaquina Head with its lighthouse and rocky sea stacks all around. It is a great place for bird watching and offers many different angles for having some photography fun.

Colony Rock is a great habitat for thousands of seabirds. We saw Common Murres, Pelagic Cormorants, lots of Western Gulls, and some other species.

NATURE CLICKS #571 - COMMON MURRE (FIRST SIGHTING)

Common Murres, Yaquina Head Outstanding Natural Area, near Newport, Oregon

Our trip to the coast of Oregon was still a little too early for a big deal of bird photography. Nevertheless, we had a few good encounters and some of them were first sightings for us. The Common Murre nests on sea cliffs above the ocean and we found them on the cliffs at Yaquina Head Light, north of Newport, OR. During breeding season they lay one egg directly on a ledge without adding nesting material. The Common Murres feed mostly on fish, squid, or octopus and catch their prey in the bill during deep dives. They use their wings for propelling themselves and can remain underwater for up to one minute. These birds look a little bit like penguins with their tuxedoed look, but they are relatives of auks and puffins.

I had plenty of images already on the memory card when suddenly this flock took off and moved to a different cliff below the lighthouse in the Yaquina Head Outstanding Natural Area.

SWANS, SWANS, AND MORE SWANS

Migrating Tundra Swans, Mississippi Valley, Green Island, Iowa

I wasn’t able to count all the swans I found yesterday at Blakes Lake in the Green Island Wetlands. I think it’s safe to say there were at least 400, but probably more, feeding in the shallow waters of the lake. Heat shimmer above the water surface made it kinda difficult to  see details of the birds in the viewfinder of the camera. While standing on the dyke there were quite a few more swans moving in and this was the chance to make a few clicks from a shorter distance. It wasn’t until I had a closer look at the birds on the screen of my computer that I realized that there were quite a few Tundra Swans among the Trumpeter Swans, which latter I had seen during the last few weeks already. This also explained the considerable increase in numbers of swans present on the lake.

While the Trumpeter Swans may stay here in eastern Iowa during the winter, the Tundra Swans spent the winter at the Mid-Atlantic coast. They are back now and on the way to their breeding grounds in the arctic region of Canada and Alaska. Trumpeter Swans are slightly bigger but this is not always a safe indicator for identification. It is the yellow spot that adult Tundra Swans show at the base of their bill that leaves no doubt about what species we see.

The yellow spot is at least very good visible in the full size photo of these two Tundra Swans flying overhead. The size reduced picture you see here in the blog makes it a little more difficult to see this important feature.

WAITING FOR SPRING

Black-capped Chickadee

It is the time of the year when we start to hear the ”fee-bee” calls of the Black-capped Chickadees more frequently. The snow bells are out in the front yard and also a couple small crocus flowers. While driving to town this morning I saw a pair of Sandhill Cranes flying across the road. All sure signs that spring is right around the corner or at least not far away anymore.

ANOTHER CHANCE WITHOUT WIRE

American Kestrel, Green Island Wetlands, Iowa

More than once I have complained about that the kestrels mostly perch on utility wires along the road, which isn’t my preferred location for a wildlife shot. Well, the solution seems to be to drive along roads that do not have power lines next to them. Not easy to find here in Iowa! This female American Kestrel used the dead trees at the edge of a marsh for her hunting efforts. During the summer these small falcons often eat insects, like grasshoppers. Since this is not an available option right now, they are on the outlook for small mammals and birds.

NATURE CLICKS #570 - TRUMPETER SWANS

Nikon Z6II, Nikon FTZ adapter, Sigma 150-600mm / f5-6.3 DG OS HSM S

This afternoon we saw at least 40-50 white dots, far away and deep in the wetlands at Green Island and assumed that a large congregation of Trumpeter Swans was there. This all got confirmed during the hour before sunset when family after family crossed the marches and lakes and flew towards the setting sun. We don’t know where they spend the night but it was nice to watch groups between two and eight swans flying towards us and overhead. Since it is such a big bird it’s not so difficult to track them in flight and practice panning technique with the long lens on camera.

BALD EAGLES IN ABUNDANCE AND AN EARLY RETURN

Bald Eagle, Mississippi Valley, Green Island Wetlands, Iowa

Yesterday I received a message from a friend that the water was open down at the Sabula - Savannah bridge that crosses the Mississippi River and both sides of the road that leads to the bridge were filled with eagles. As wildlife photographers we have to take the opportunities when they occur and as the ice on the river disappears, many eagles quickly move upstream. I went down south this morning and the first chance came already while driving slowly through the Green Island Wetlands. There is a big solitary cottonwood tree next to one of the dikes and this adult Bald Eagle just posed nicely against a blue sky and the unavoidable clutter of small branches. This tree has served many times as a perch for eagles and other raptors over the years but it is in bad shape and might be gone sometime soon. I moved with the camera so the white head of the bird was in front of one of the bigger branches.

Down near the Sabula - Savannah Bridge were still dozens of Bald Eagles. The downside is you can’t stop and park your car along the road that connects the Sabula island with the actual bridge, except for a small pull-out right at the bridge. I was lucky, one eagle had perched within the reach of my lens and this time against a clean background. Later I had some other opportunities but this was my favorite shot.

Sandhill Crane among Trumpeter Swans, Green Island Wetlands, Iowa, February 11, 2024

Hours later, on my way back home, I made another round through the Green Island Wetlands and had an interesting discovery. The ice where nine Trumpeter Swans rested earlier had melted and they were foraging in the shallow water of a flooded field. Among them was a solitary Sandhill Crane, searching for food as well. It moved with the swans and seemed to take advantage of whatever was stirred up while they swam slowly across the water.

At home I checked my digital photo library, going back to 2007, and can confirm, February 11th is the earliest I ever saw a Sandhill Crane here in eastern Iowa. Seeing them in March is not uncommon but this early was my first time. Other birders may have made a different experience and I like to hear from you about your observations in this area.

NATURE CLICKS #569 - AMERICAN KESTREL

American Kestrel, Green Island Wetlands, Mississippi Valley, Iowa

Here is another image from last weekend’s visit to the Green Island Wetlands. I was already pretty happy since I just had photographed the Rough-legged Hawk I showed in my last blog post. A few minutes later, on my way out on the muddy road, this American Kestrel just landed on a branch in front of me. With a slight turn of the car and the window down I was able to make a few clicks of this small falcon. I have written about in the blog before, the American Kestrel perches nine times out of ten on a utility wire between the poles. The bird gave me less than a minute and half of the time it looked away from me. Having the kestrel sitting actually on a tree branch is much harder to get and with the warm light of the setting sun, this is definitely a keeper.

NOT ”SKUNKED” AGAIN

Rough-legged Hawk, Green Island Wetlands, Mississippi Valley, Iowa

I have been at Green Island, the wetlands down south in the Mississippi Valley, the third time in a row during the last weekends and after getting ”skunked” twice, I came finally back with some photos on the memory card today. I know that a number of local fellow photographers and birders follow my blog and I like to report about the sightings first today.

While I was even further south in Sabula, Iowa my hopes to get some Bald Eagles in front of the lens did not came true. There was still too much ice on most parts of the Mississippi River and the eagles had no reason to be there due to the lack of open water.

At the Green Island Wetlands I found to my surprise 100+ migrating Greater White-fronted Geese. Among them was one single Snow Goose and a school of seven Trumpeter Swans had joined the party as well. This was all too far away for a decent photo, but I enjoyed watching the birds through the binoculars. The picture below is from 2019.

New photo opportunities came during the hour before sunset. While driving through the mud on the west side of the wetlands this Rough-legged Hawk seemed to take advantage of my presence. It let me come really close with the car, took off and flew to the next tree ahead. This repeated several times. Maybe the bird was hoping my movement would startle other birds or rodents along the muddy road. There was only one stop that would allow a shot without any obstruction. Of course, I took my chance!

Rough-legged Hawks breed in the tundra and taiga of North America and Eurasia. They migrate to the Central US for the winter. An area with marshes and fields, like the Green Island Wetlands and with rodent prey present, is their preferred habitat. More to come…

FUN IN THE SETTING SUN

Downy Woodpecker, Little Maquoketa Valley, Iowa

The sun came out finally this afternoon, reason enough to spent the hour before sunset behind the camera with the SIGMA 150-600 S attached. With the much warmer weather the birds seemed to visit the feeders less frequently and some patience was required at times. Most of the snow has melted away but in our front yard was still plenty enough to bounce the light upwards. With the sun sitting low above the ridge, the natural light had a nice quality and I didn’t employ a speed light for better color control this time.

Before the woodpeckers approach a suet feeder they carefully check the surrounding area from a nearby tree or shrub. This is the moment I’m mostly waiting for. Just fun in the setting sun…
