California Gull with nesting material

A little over a week ago I was photographing a perched Loggerhead Shrike on Antelope Island when I noticed a California Gull (Larus californicus) flying towards me with a bill full of something that didn’t look like food.

As the gull came closer to me I could see that it was some type of vegetation and I knew then it had a bill full of nesting material. California Gulls nest nearby on Egg Island and that is the direction that the gull was flying towards. It was the first time I have been able to photograph a California Gull with nesting material so I was quite pleased. though I wish I had backed up my zoom all the way, I might have been able to fit the whole bird in the frame.

I photographed this California Gull along the causeway to the island last year, it looks like it is in the middle of a molt because some of the feather on the wing are a touch ragged.

Yesterday while I was out photographing Long-billed Curlews this California Gull (Larus californicus) flew in so close that all I could do was take portraits of the bird. After a long holiday weekend and the abundance of campers on Antelope Island State Park, I’m fairly certain the bird was looking for a hand out. I could see other gulls scouring the campsites for any scraps of food left behind.

I like the out of focus, tiny pink wildflowers that are currently blanketing the grasslands of the island showing in the background, the snowy white plumage of the gull, the bits of oolitic sand on the bird’s bill and the brilliant colors of the gape, orbital ring and bill. I also rather enjoy being able to see the reflection of the fluffy clouds in the sky in the upper quadrant of the gull’s dark eye.

You’d think that Utah would have selected a different species for the State Bird given that the name of this species is the California Gull. I’ve written about why the California Gull was picked for the Utah State Bird here, it is an interesting story.

Oh, the Biting Gnats (no-see-ums) are back and bit me up yesterday. Grumble, grumble.

California Gull on a Windy Day

Yesterday morning a light snow had covered most of Antelope Island while the normally lovely blue of the Great Salt Lake was instead a grayish brown because gale force winds were churning it up and there were white caps as far I could see. The lake is very shallow so it doesn’t take much wave action to stir up the sand, mud and particulates.

Choppy waters in the Great Salt Lake

This image taken from the Egg Island Overlook shows the choppy waters on the Great Salt Lake caused by the strong winds. Most of the birds on the island seemed to have hunkered down to escape the wind, even the ever-present Horned Larks couldn’t be found perching on rocks and sightings of Meadowlarks singing on the tops of Sagebrush were few and far between.

California Gull in flight

There were large flocks of California Gulls (Larus californicus) along the shoreline bobbing in the waves and those in flight were buffeted by the wind, I had trouble keeping my lens steady because of it too. I was almost glad to head home to get the sound of the howling wind out of my ears… almost. I don’t ever seem to get my fill of the island though.

Wild and Wonderful – Antelope Island State Park – The Birds

This is the third post in my series about Wild and Wonderful Antelope Island State Park, I’ve saved the best (and longest) for last. The Birds! Okay, maybe they aren’t the best thing about Antelope Island State Park, but I am a bird photographer and they are what I am most passionate about!

Birds of Antelope Island:

Before I get to the avian life of the island I’d like to provide a link from UtahBirds.org that has a checklist of the birds of Antelope Island that is downloadable. If you need ID help for the birds found on the island UtahBirds.org has a great photo gallery of the various species put together by the wonderful Milt Moody that are contributed by local bird photographers that can assist in ID.

Upland Game Birds:

Feeding Chukar (Alectoris chukar)

Chukars are the most visible of the upland game birds that inhabit the island, they do not migrate so they can be seen all year round. Although they are not native to North America the Chukars on Antelope Island have adapted well to their adopted home. My first sighting of a Chukar in the wild was on Antelope Island and I am still as thrilled today to photograph them as I was on my first to the island.

Other upland game birds that can be seen on the island are Ring-necked Pheasants, California Quail and I’ve seen Sharp-tailed Grouse there as well. Thankfully the birds on Antelope Island are not hunted.

Gulls:

The Great Salt Lake and its surrounding marshes are a magnet for birds like gulls and terns. The Utah State Bird is the California Gull and it is often visible along the causeway to the island, the shoreline, in flight over the island and can also be found perched on the pavilions near the campgrounds and the Buffalo Grill.

I believe that although gulls are common they can be uncommonly beautiful photographed in the right light, in a great pose or interesting habitat.

Shorebirds:

Nikon D200, f6.3, 1/320, ISO 400, Nikkor 200-400mm VR with 1.4x TC at 400mm

There are many shorebirds that visit Antelope Island, the causeway to the island and the surrounding freshwater marshes, too many for me to post an image of each one so I will just post a few. I counted 35 on the checklist but some of those are rare vagrants, still that is a lot!

Some of the shorebirds are just passing through the Salt Lake Valley during their migration further north to their breeding ground, the Killdeer pictured above nests on the island along with several other species.

Willet (Tringa semipalmata) wing lift

Willets are another species of the shorebirds that nest on the island, prior to breeding season they can be seen quite often along the causeway but when they are nesting they can be seen in the grasses and on the rocks along the road. They let their presence be known by loud calling and wing displays. The bird above was displaying because another Willet was nearby and they don’t seem to care for intruders on their territory.

Male Long-billed Curlew (Numenius americanus)

It won’t be very much longer before the Long-billed Curlews return to nest on Antelope Island and until I can hear their hauntingly beautiful calls. In Florida I never heard the calls of these graceful shorebirds, it is call that once you hear it, you’ll never forget it. I am very much looking forward to their return.

In the summer the calls of American Avocets and Black-necked Stilts can easily be heard along the causeway and their numbers are in the thousands (and thousands). There are just so many shorebirds present at times I can’t post a photo of them all but the checklist I linked to above shows all of the species.

Perching Birds:

Black-billed Magpie (Pica hudsonia) on nest

There are also more perching birds on the island than I can list, I didn’t even try to count them so I’ll just post some images of the ones I see often like this Black-billed Magpie on top of its nest. Black-billed Magpies are great fun to observe and photograph at any time of the year. Some people call them noisy but as a bird lover their raucous calls are music to my ears.

Common Ravens are in the Jay, Crow and Allies family along with the Black-billed Magpies and they are among the smartest birds in the world. They can bee seen flying all over Antelope Island, on the ground, perched on bushes or harassing other birds and animals. Just yesterday alone I saw them harassing Northern Harriers, a lone Coyote on a hill and a Rough-legged Hawk. Fiesty and fun!

Male Brewer's Blackbird (Euphagus cyanocephalus) displaying on sagebrush

Nikon D200, f7.1, 1/500, ISO 400, Nikkor 200-400mm VR with 1.4x Tc at 400mm

There are several different species of Blackbirds present on the island which include Brewer’s Blackbirds, the bird above is displaying for a female who was just outside of this frame. I love the beautiful iridescence that can been seen in their plumage when the light is at the right angle.

Western Meadowlark (Sturnella neglecta) singing in early spring

I don’t believe I have ever made a visit to Antelope Island without hearing or seeing Western Meadowlarks. Ever. During breeding season they seem unable to stop singing, you can tell they are trying to not sing but it just bursts forth anyway.  And when they are feeding nestlings it is not uncommon to see them with 25 or more bugs in their bills. I don’t know how they don’t drop them all.

Male Horned Lark (Eremophila alpestris)

Horned Larks are also year round residents on the island, they delight me with their soft calls while perched on rocks and in flight. I love their subtle coloration, the little bit of yellow on their faces and those tiny little horns. They can be seen out in the open, feeding in the grasses, perched on signs and singing from the top of boulders that dot the island. I can’t resist taking photos of them.

Sage Thrasher (Oreoscoptes montanus) juvenile

Sage Thrashers are part-time residents of Antelope Island that breed and nest during the summer. Some years they show up in large numbers while other years there just aren’t as many. I love to see them flitting from one sage brush to another or perched on the boulders like the juvenile shown above. I miss them during the winter but I know I’ll get to see them again soon.

Perched Loggerhead Shrike (Lanius ludovicianus)

I am always tickled to see Loggerhead Shrikes on the island and normally I hear them just before I see them. They are classified as “songbirds” and they really do sing but to me they look and act like small raptors. They are fierce, aggressive and very interesting birds. During the winter their cousins; the Northern Shrikes can also been seen on the island, this winter I have seen a few but too far away to get decent images of them.

There are sparrows, doves, warbler, wrens, vireos, tanagers and many more perching birds that live on or visit Antelope Island, it is such a bird magnet!

Pelicans:

Nikon D200, f7.1, 1/1000, ISO 250, Nikkor 200-400mm VR with 1.4x TC at 400mm

American White Pelicans breed in the Great Salt Lake area and it isn’t uncommon to see large flocks of them soaring in the thermals on clear days. These are huge birds with wingspans of up to 108 inches, nearly 30 inches longer than their relative the Brown Pelican. They are graceful and beautiful in flight.

Their cousins; the Double-crested Cormorants, are also seen in flight over the island from about March until late fall.

Ducks and Grebes:

Nikon D300, f6.3, 1/2000, ISO 640, Nikkor 200-400mm VR with 1.4x TC at 400mm

Swans, geese and many species of ducks can be found in the waters of the Great Salt Lake and nearby freshwater marshes, I counted 29 of them on the bird checklist for Antelope Island.  Autumn and winter is awesome for seeing ducks along the causeway which sometimes number well over thousands within plain view.

For my Florida friends:  yes, we actually get surf on the Great Salt Lake when the winds are strong and our ducks seem to enjoy surfing!

Other water birds that can be sen on the lake are five species of Grebes, American Coots and occasionally Common Loons.

Hawks, Eagles and Falcons:

Antelope Island State Park is home year round for Golden Eagles and Bald Eagles are a common sight during the winter with fly overs and Bald Eagles sitting on the ice of the Great Salt Lake. Northern Harriers are year round residents that cruise along the causeway to the island, near the shorelines and over other areas of the island itself. Northern Harriers prefer voles as their diet and there must be plenty of those around to support the numbers of harriers that I have seen.

Osprey are seen flying over the island during migration, they don’t fish in the Great Salt Lake because it is too saline for fish to live in but they do fish in the surrounding freshwater marshes and ponds.

Rough-legged Hawk (Buteo lagopus) in flight

Rough-legged Hawks have been plentiful on the island this winter and I have been overjoyed with that happening. I have been able to observe them hunting, hovering, eating, perching, having aerial fights with each other, swooping towards their prey and in flight. I have learned much more about this species habits because they have been so abundant.

Other hawks that are found on the island include Sharp-shinned, Cooper’s, Red-tailed and Swainson’s Hawks.

American Kestrel (Falco sparverius) male

Then there are the Falcons of Antelope Island. This beautiful little American Kestrel male was perched on a snow covered shrub while keeping an eye on me. They are the smallest falcon in North America but I don’t think they know that, I’ve seen them dive bombing much larger birds than themselves. Feisty and small, that is what my mother used to say about me.

Peregrine Falcons are permanent residents of the Antelope Island area, during warmer months they often feed on a variety of shorebirds and during the winter they eat ducks like this Northern Shoveler. Inflight they are very challenging to photograph because they fly so fast. This falcon wasn’t bothered by my presence as it ate but it did keep an eye on me at times.

Prairie Falcons are another year round resident of the area and I have had a great time this winter photographing them. Until this winter they were a nemesis bird for me, always too far away to get good photographs of, but they are a nemesis no more.

Merlins are seen during the winter on the island and the causeway, I’m still working on getting some images of them from the Antelope Island area.

Owls:

Barn Owls nest on the island and nearby locations, when the adults are feeding chicks they can be seen in flight during daylight. When we have a hard winter (and this year we are not) they can be seen hunting all day long. This Barn Owl was hunting near the beginning of the causeway to the island which is marshy and it has the mud on its feet from pouncing on prey.

Great Horned Owl (Bubo virginianus) adult

Great Horned Owls can be seen and photographed in several locations on the island and are permanent residents. Since I was a child I have always been fascinated by Great Horned Owls so I am always thrilled to have an opportunity to photograph them.

Juvenile Burrowing Owl (Athene cunicularia) flapping its wings

Nikon D200, f6.3, 1/1600, ISO 400, Nikkor 200-400mm VR with 1.4x TC at 400mm

I simply adore Burrowing Owls, they are little, cute, funny and stunningly beautiful. They are a pleasure to photograph and because they are often very animated it can be hilarious too. I have had to hold my breath to squelch my laughter at times just so my camera and lens wouldn’t shake.

Other Owls that are seen on Antelope Island are Short-eared and Long-eared Owls. Northern Saw-whet Owls have also been seen and this winter there was a Snowy Owl reported along the causeway which turned out to be “A One day Wonder”, I would have loved to have a few images of that visitor from the Great White North. Maybe another year.

There are other birds of Antelope Island whose images aren’t here, there are simply too many for a blog post. Perhaps I should create a book.

Thanks for looking at the series of images and my thoughts from Wild and Wonderful ~ Antelope Island State Park!

California Gulls feeding on the Brine Flies of the Great Salt Lake

A few days ago I had the opportunity to take images of California Gulls feeding on brine flies along shoreline of the Great Salt Lake next to the causeway to Antelope Island State Park, which is something I have wanted to do since I moved to Utah a few years ago. The first time I saw this behavior I thought it was very comical as well as interesting and wanted to document the behavior with photographs.

When visiting Antelope Island State Park during the summer I can often see piles of the pupal casings of brine flies on the shoreline that have been blown there by the wind. Perhaps “piles”  is a bit of an understatement since there can be over a billion pupal casings in a one mile stretch of shoreline. They remind me of the mounds of Turtle Grass I’d often see on the wrack line on the beaches of Florida but in this case it isn’t grasses but the shed casings of the pupae of the brine flies.

The shoreline  and the surface of water nearest to the shore is also dark with the newly emerged brine flies themselves, millions of them! They seem to move in choreographed mass when anything approaches them.

Though other bird species feed on the brine flies of the Great Salt Lake I find the way that California Gulls do it in the most humorous and entertaining way. Franklin’s Gulls seem to stay in one place then as the flies move past them they snap their bills to capture the flies. Many of the shorebirds; like the out of focus Black-necked Stilt above pick the flies off of the water.

The California Gulls seem to stake out a stretch of the shoreline as their territory and chase off other gulls that enter it by spreading their wings and running after the “intruder”. They do not seem to mind resting gulls though and they don’t chase them off. In the photo above the gull in the foreground is actively chasing after the brine flies while the other resting gull appears to be taking advantage of the first gull’s chase by passively feeding on the flies stirred up by the other one’s movement.

It is quite a challenge to photograph the gulls during their chases of the brine flies as there are times the camera wants to focus on the mass of flies rather than the birds. I had begun to think the only way for me to get the gulls sharp was to manually focus on them but gave up on that idea because the gulls move through so fast. I used auto focus instead and it seemed to do well though I have a bunch of out of focus gull photos I will simply delete.

Most of the time the California Gulls lower their heads, scrunch their bodies down and then begin to chase the flies where they are floating on the water while snapping their bills closed around the flies. At other times they lift and spread their wings during the chase which appears to act something like a “scoop” or a “net”. As the gulls move in the direction of the flies , the water which had appeared black because there are so many thousands of flies concentrated there briefly turns blue again as the flies take flight. Rocks or other debris along the shoreline also turns black with the masses of flies that land on them.

There are two main species of brine flies that inhabit the Great Salt Lake,  Ephydra hians and Ephydra cinerea, of the two the Ephydra hians is the largest in size but only accounts for about 1% of the total population of brine flies that live in the Great Salt Lake area.

The individual California Gull’s “hunting” territory appears to be about 25 to 30 feet in length, they chase the length of the shoreline, stop for a few seconds then turn and chase in the opposite direction. I have wondered how many of the brine flies the gulls consume during their fast moving forays through the cloud of flies as it appears the gulls expend a lot of energy in the chase.

Brine Flies live most of their lives underwater as larvae who feed on cyanobacteria, other bacterias, diatoms, detritus and bottom-dwelling algae. After the larval stage of a brine fly’s life it grows a pupal case while it changes into an adult by a process called metamorphosis. Adults only live for a few days and the females deposit their eggs. Larvae over winter in the lake and as soon as it warms up again in the spring, the cycle continues.

In this last image I wanted to show just how thick in the air that the brine flies can be while the gulls are chasing after them.

I thought I might be able to add some more images of California Gulls chasing brine flies when I visited there today, but the weather conditions weren’t right. The strong south wind must have been keeping the brine flies from that section of the shoreline. I’m just glad I had the chance to photograph the California Gull’s feeding on the brine flies and capturing the behavior.
