SHOREBIRD ARRIVALS

Every year in late winter I’m in joyful anticipation for the arrival of migrating shore birds. It is fun to watch them how they search for food in the shallow water and on the mud banks. Creating some pictures of the birds can be very tricky at this time of the season, as I had to experience again yesterday afternoon. The biggest challenge is often heat shimmer above the water or the ground, which makes obtaining a sharp focus sometimes even impossible. I go out early, even if the light is sometimes not the best in the early afternoon, but I like to have time to scout the location and see who is there and where is the best chance to make a decent image maybe later in the day.

In addition to the bird species I’m able to present here were also a couple Pectoral Sandpipers in the Green Island Wetlands, but they were too far away for a usable photo. All images were made between 5.19PM and 5.46PM, when the sun had slowed down and the heat shimmer was not an issue anymore. And of course, the light on the birds had a warm touch and was by far not as harsh as still during the mid afternoon.

Wilson’s Snipes. I have never seen so many of this species in the Green Island Wetlands and reported 28 on eBird yesterday, but I’m sure there were even a few more. Counting birds and making photos at the same time doesn’t always go well together… 😉

They probe fast like a sawing machine with their very long bill in the mud for larval insects, crustaceans, mollusks, and earthworms.

Greater Yellowleg. This sandpiper can be watched feeding mostly in shallow water. I don’t see them often on the mud flats. Their diet consists small aquatic and terrestrial invertebrates, small fish, seeds, and berries. Six Greater Yellowlegs were present yesterday evening.

The first Killdeers arrived already in February. Their call is distinctive and leaves no doubt who is present. They sometimes tap the ground with one foot to draw out prey and I watched this one doing it several times. They feed on insects and invertebrates.

USING THE WINGS

Brown Creeper, getting up a tree

It was a great day of looking for birds during spring migration in gorgeous weather but I need some time to go through all of the images I shot this afternoon in the Green Island Wetlands. Instead a photo from last weekend is posted today. If you are a follower of my blog, you may know from previous articles in the past that I’m really excited about the presence of two Brown Creepers here in our woods. For my German friends, it is a cousin of the ”Baumläufer”, a tiny woodland bird that spirals up tree trunks in search for insects and their larvas.

They glean, probe, and peck at the trunk with their long, down-curved bills. Starting near the bottom of the trunk, they work their way up the tree to within several feet of the top, then fly to the bottom of another tree (or sometimes the same one) to begin again.

The Brown Creeper you see here didn’t just hop up the tree trunk but used its wings to get to a higher spot. Getting any image of these very fast moving birds is already a reward, but catching them in flight is just priceless in my books…

COLLECTIVE EFFORTS

American White Pelicans, Mississippi River, Lower Sabula Lake, Iowa

It was so nice to see some colors again after a gray and nasty cold day yesterday. It was a good Sunday for checking out spring migration of the birds along the Mississippi again.

I have never seen so many pelicans fishing together before. This squadron contained more than a hundred birds, with many more on the water around, but choices had to be made what to leave in the frame and what not. First it looked and sounded like they all were fighting for the fish but pretty soon it was clear that it was a well organized collective effort by these American White Pelicans, as you can see in the second picture. I don’t know who was in charge to give the command, but suddenly they all took off and flew across the water to a different spot and started all over hunting for fish again.

ENJOYING THE TRUMPETERS

Trumpeter Swans, Mississippi River, Potosi, Wisconsin

I spent quite a bit of time on both sides of the mighty Mississippi River this weekend and like to share a some photos with you in the next few days.

This morning I saw about 25 Trumpeter Swans at the end of the John Deere dyke here on the Iowa side but all too far in the distance for a picture. A different scenario this afternoon at the Potosi boat landing on the Wisconsin side of the river, where close to 100 swans had congregated. Several family groups were feeding, resting, or socializing with each other and their loud trumpeting calls, that sound like a french horn, could not be missed.

Trumpeter Swans feed mostly with their head under water. I watched them today using their webbed feet to stir up roots. An adult swan eats up to 20 pounds (~10 kg) of food per day.

KILLDEER IN MIGRATION

Killdeer, Mississippi Valley, Green Island, Iowa

A couple days ago I spent the evening in the Green Island Wetlands, hoping for some good light and maybe spotting some migrating shorebirds. I’m not very good at counting large numbers of birds but I estimated about 200 Killdeer on one of the mudflats that have been under water for quite some time during the flooding we had in July. Food was obviously there in abundance. The birds were too far away and the camera stayed in my lap while watching them.

Later, an hour before sunset, I moved to a big puddle on the westside where I had good luck with sandpipers earlier this season. First I had only three Killdeer feeding in the shallow water or in the mud, but at the end, shortly before sunset, I was able to choose from about two dozen birds which one to get in the viewfinder. The Killdeer is one of the earliest birds that arrive after the winter and they are building their nests in shallow ground depressions in gravelly areas, like parking lots or in fields. It’s hard to tell which bird is a juvenile, they all have nearly the same size. The Killdeer is a common bird here during the summer but I have never seen so many at the same time. I’m glad I didn’t miss them during their migration to the South this year.

NATURE CLICKS #573 - PECTORAL SANDPIPER

Pectoral Sandpipers, Upper Mississippi Valley, Green Island Wetlands, Iowa

Last weekend ended with a short visit in the Green Island Wetlands, the area 40 miles south of our home that includes a wildlife preserve and a mix of lakes and marshland, separated from the main channel of the Mississippi River by dikes.

I saw Wood Ducks in their best mating mood, Sandhill Cranes, some pairs of Canada Geese with little goslings, Hooded Mergansers, a number of Pied-billed Grebes, and again two migrating Greater Yellowlegs.

As the sun got ready to set, a last drive along the gravel road on the west side of the wetlands led to the discovery of 30 Pectoral Sandpipers, foraging in a big puddle at the edge of a field. Their breeding grounds are high up in the arctic tundra of Canada and they obviously stopped at Green Island for some re-fueling. Their bills probed into the water and mud with high frequency in search for invertebrates. I used my car as a blind and moved slowly in the field towards the puddle. The sandpipers didn’t seem to take any notice of my presence and kept feeding.

Moments like that keep me going and feed my passion for bird watching and reporting about it here in the blog. The Pectoral Sandpipers spent the winter down in South America and their long journey to the breeding grounds up on the arctic tundra is just amazing.

I shot this at 850 mm with the 1.4 teleconverter attached to the Sigma 150-600 S lens. A small, cosmetic crop was applied to the final image.

LEARNING HOW TO FEED

Juvenile and adult Sandhill Cranes, Heritage Ponds, Dubuque, Iowa

Despite spending some time with aviation photography during recent days I still had a chance to make some wildlife images as well. I saw a pair of Sandhill Cranes with their chick a month ago while riding my bicycle down in the valley. The best camera you have is always the one that is with you, and in this matter I just snapped a couple pictures with the camera in my phone. Last Friday I watched the cranes again and the juvenile on the left had grown quite a bit already. This time I was prepared and had the right gear in the car.

How do birds learn what to eat, where to find the food, and how to catch it? Although the young cranes begin to feed themselves during the second week, as you can see, this young bird was still not probing with its bill in the mud of the very shallow pond. It just watched one of the adults closely and waited patiently until mom or dad found something, like a tadpole or frog. The second photo shows the other adult, just briefly interrupting its intense search for food. The color of their heads tells the story about a hungry chick that still needs some support…

FLIP THE CRAB

Snowy Egret eating a crab, Bolsa Chica Ecological Reserve, Huntington Beach, California

The light was a little dull when I had this Snowy Egret in the viewfinder, but when the bird caught a crab and tried to eat it, I let the shutter rip at high speed. The egret flipped the crab in the air, caught it again with its bill, and finally swallowed it.

It was a chilly morning at the Bolsa Chica Wetlands (Los Angeles had even a little bit of snow a few days earlier). Most Snowy Egrets had gathered in a corner of the lagoon and preened their feathers in the warm sun.

I have to show at least one picture of a Snowy Egret with its black legs and big yellow feet out of the water.

NATURE CLICKS #545 - BUSHTIT (FIRST SIGHTING)

Bushtit, San Joaquin Marsh Wildlife Sanctuary, Irvine, California

It all started last Friday afternoon after I was done with all my business duties in the area south of Los Angeles, CA. I headed straight to the San Joaquin Marsh Wildlife Sanctuary, a heaven for every bird and wildlife lover in the heart of Orange County. It encompasses 300 acres (121 ha) of coastal freshwater wetlands, half of it restored to a natural state, the other half is in no need of restoration (source: Irvine Ranch Water District website).

It took me only a few minutes to walk with the camera on tripod on the shoulder until I made a new ”first sighting”. The Bushtit is a tiny bird with a stubby bill and a long tail that prefers a brushy chaparral habitat. I found a little flock of about twenty birds, buzzing and moving around quickly between the flowers that grow along the trails between the ponds in the wetlands. They feed mostly on small insects and spiders. The females have pale eyes, while the males and juveniles have dark eyes.

There was no way that I would get a picture with the camera on tripod with the little Bushtits moving from one flower to the next very quickly. I tried not to move around erratically with the heavy long lens attached, so I focussed on an area and followed the birds as they moved along.

The Bushtit is only found in the western part of the US and Mexico. They are not uncommon but it was my first sighting of this tiny agile bird. Can’t asked for a better start into a birding weekend… More to come, please stay tuned….

NATURE CLICKS #544 - AMERICAN WHITE PELICAN

American White Pelicans, Mississippi River, lock & dam #14, LeClaire, Iowa

The American White Pelican needs open water to make a living. They feed on fish while swimming and snatch prey with their large bills. I made a trip today down south to lock & dam #14 near LeClaire, Iowa and there was plenty of open water. The ice cover of the river lasted only in quiet bays and backwaters with very little or no current. I was hoping to find Common Mergansers at the exit of the lock but had no luck. Instead a squadron of six pelicans cruised the water back and forth. They always work together as a group while trying to catch fish and it is such a pleasure to watch these majestic birds. Unlike their cousins, the Brown Pelicans, who live a long the Pacific, Atlantic, and Gulf coast, White Pelicans do not plunge dive for food.

It is very easy to blow out the highlights in the pelican’s plumage when the sun is shining. I underexpose by at least 1 stop to prevent this. It’s always possible to brighten the water a little bit if you think this is necessary, but a blown out highlight is a lost cause.

NATURE CLICKS #487 - KILLDEER

Killdeer, Green Island Preserve, Iowa

It looks like they are always motionless but the Killdeer can actually run pretty fast as soon they spot something to eat, like an earthworm or insect. It is one of the first bird species that returns after the winter and before you see them, you just know they are there because of the loud cry they can emit, “kill-dee” or “kill-deeeah-dee-dee”.

I have reported about Killdeer many times here in my blog before and if you use the search window you can compare older notes about this large plover. Last Sunday I watched a pair  feeding on earthworms that came out of the ground after the rain.

NATURE CLICKS #468 - MOUNTAIN BLUEBIRD

Mountain Bluebird, Little Missouri National Grassland, North Dakota

In many locations we camped or visited during our trip there was a good chance to watch some Mountain Bluebirds. Quite often they forage from a perch, like a fence, twig, or rock. They drop down to the ground to catch insects but they also hover above their prey before they make a catch. Beside insects the bluebird takes also fruits and berries.

They like to keep their distance and many photos of Mountain Bluebirds I made during previous years had to be cropped. This female was perched on a young eastern cedar in our campground, just outside of Theodore Roosevelt National Park, North Dakota. The light was soft and the background far away, ideal for such an image.

THE LOOK

Common Grackle, Mud Lake, Mississippi River, Iowa. Shot from the kayak.

With its beak full of food, the Common Grackle gives me “the look”. Not as common as the Red-winged Blackbird and hardly standing still. With their irresistible eyes and iridescent feathers I can forget about the duck weed and the bubbly muddy water around the bird and wanted to make the photo.

NATURE CLICKS #454 - SCARLET TANAGER

Scarlet Tanager ♂️

Male and female Scarlet Tanagers are some of the prettiest visitors we have here at this time of the year. The tanagers like this oak in front of the house as a landing place before they approach the suet feeder. The frost at night a few days ago has damaged some of the fresh leaves on this young oak but the tree recovers quickly. With the cold weather we had lately these neotropical migrants come in very frequently. Later during the summer they spend most of their time in the canopy of the forest and forage for insects. That’s when we hardly see them anymore.

NATURE CLICKS #450 - SORA

Sora, Green Island Wetlands, Mississippi Valley, Iowa

I found another Wilson’s Snipe last Saturday at the same spot where I had taken a picture a week earlier, but a day later we didn’t see any of them. With the warm weather they may have moved on further north. Instead we found two Sora in the same habitat along the wooded, water-filled canal that borders the Green Island Road. The Sora is the most common and widely distributed rail in North America but it is a small secretive bird that lives in freshwater marshes and is not always easy to locate. They move very fast while feeding and foraging between old vegetation in the shallow water. With the dappled light between the trees it was quite a challenge to get a sharp and halfway correct exposed picture. A bird we always enjoy seeing!
