Blue-winged Teal in red crystal waters...

I saw this beautiful Blue-winged Teal couple in the Ding Darling NWR on Sanibel Island, Florida. They were swimming in the channel off the Indigo Trail quietly moving in and out of the mangrove roots. The water was dull and murky with a slight reddish-brown cast, but when the couple moved into an area of deep shadow sprinkled with pockets of filtered sunlight, an optical illusion brought the water to life. Wherever the sun struck the murky water, fiery red color seemed to rise up from below, as if it was being lit by flaming crystals underneath...

The male Blue-winged teal left a stream of fiery color in his wake. What an unusual sight!! I'd never seen anything like it before, and on my return walk, the illusion was gone.

A male Blue-winged Teal in breeding plumage is so striking. I love spotting the white crescent-shaped mark on his face and the white circular patch near his tail. If you look sideways and combine his reflection, he looks like an eerie owl with huge white eyes. His speckled chest and sides add to the owlish look. When I was photographing him, the owl illusion really jumped out. The whole scene was surreal...creepy...and Scooby Dooby Doo-ish!

...can this water be real? You would think red "mood" lighting had been installed underneath as an added attraction for tourists...sort of like the old disco floors...

Disco ducks?

...eventually the Blue-winged Teal couple left the deep shadows....

...and came out into the light. The glowing reds left the water, but a small patch of his his famous sky-blue wing coverts became visible instead!

I photographed these birds last March. I wish I were in Florida now, though!

An Anhinga sitting on a nest...

I almost missed this male Anhinga sitting on a nest. With his dark head held skyward, he bordered on invisible. You would think a big black and white bird would stand out in a sea of green leaves, but he didn't. His upward tilting head must have tricked my brain into thinking it was a branch and his dark feathers were shadows, but I was lucky because it was a hot day, and the fluttering of his gular pouch gave him away. The movement, made to help regulate his body temperature, was just enough to bring my eye back to his location....and there he was. Wow! My first nesting Anhinga at Pinckney Island...

An incredibly beautiful bird, this male Anhinga sat patiently on the nest incubating eggs. Males have mostly black body plumage. During the breeding season they develop a shaggy crest and mane, which are not apparent in this photo, but you can see the "filoplumes" on the sides of the face and neck. These feathers are silky and almost hairlike.

Anhingas are aquatic birds that do their hunting under the water. With their necks coiled back, they hold their bills open a little, so when they do strike with those sharp and pointed bills, they leave two puncture marks. After Anhingas eat, they climb up on a branch and open their water-logged wings to dry.

The ability of an Anhinga to strike out with lighting speed to impale its prey on its sharp bill while underwater is because of a hinge-like mechanism between the eight and ninth cervical vertebrae, and a keel on the underside between the fifth and seventh cervical vertebrae that muscles attach to. When this hinge-like mechanism is sprung, the muscles propel the bill forward like a spear being thrown (similar to herons and egrets). I wanted to see what this looked like and found a very cool drawing of a skeleton of an Anhinga's neck showing the muscles and hinge from 1913--click here for the drawing (sources: "National Geographic Reference Atlas to the Birds of North America," Mel Baughman, pg. 64--one of my favorite reference books, and a Wikipedia article on Darters, here.)

Note: The drawing of the Anhinga's spine is from "Die Vogel: Handbuch der Systematischen Ornithologie, Volume 1," by Anton Reichenow. Click here for a link to the book. If you speak German and like old pen and ink drawings, you'll like looking through the book.

A female Anhinga perches on a limb. Females and juveniles have buff-colored heads, necks and chests.

Look at those feet! I would never have guessed that Anhingas could climb trees, but they can. Their webbed feet are equipped with powerful claws that let them climb from the ground up to their nests. Anhingas build their nests over water, but not high in a tree. They like to keep them low enough so they can climb up into them. This nest was located about 15 feet off the ground. We don't have Anhingas here in Cincinnati. They are a strictly a southeastern bird, so I don't get to spend a lot of time watching them and had never seen one climb up a tree. Within two weeks of hatching, baby Anhingas can fall out of the nest into the water below them. To get back to their nest, they climb up the trunk using their claws (source: Baughman, pg. 65).

Water Turkey!
Because an Anhinga's tail feathers resemble a turkey's with a striped pattern and a pale tip, they've been given the nickname of Water Turkey (very fitting for this time of year...).

Hanging the feathers out to dry...
Anhingas, like Cormorants, do not apply waterproofing oils to their feathers to make them waterproof. Instead, the unprotected feathers absorb water, which allows them to stay submerged and swim easily under water.

Feathers that absorb water lose their insulating properties, which causes Anhingas and Cormorants to lose body heat, so when we see them hanging their feathers out to dry, they are also using the sun's heat to stabilize their body temperature. Most of us already knew this, but what I didn't know was Anhingas have a very low metabolic rate and become chilled easily. They are dependent on the sun's heat to ward of hypothermia. As a result, they can spend up to a third of their daylight hours sunning (much more than a cormorant). It also explains why we often see Double-crested Cormorants in Ohio, but almost never see Anhingas (I've never seen an Anhinga in Ohio). An Anhinga's normal territory is the subtropical southeast
(source: Baughman, pg. 65).

Snakebird!
Since the Anhinga's feathers are not waterproof, when they get wet, they look shiny and very smooth. When you couple that with a submerged body, a long skinny neck, and a slim head, instead of looking like a bird in the water, it looks like a black snake swimming along, which leads to its second nickname, Snakebird!

I took these photos on June 8, 2011 at the Ibis Pond rookery on Pinckney Island NWR in Hilton Head, SC, except for the last photo, which I took on March 22, 2011 at the Ding Darling NWR.

A Pied-billed Grebe Couple at Ding Darling...

...when Matty and I saw these two Pied-billed Grebes swimming side by side, we thought it was a mama and a baby, but then we did a second take. It was only March 22, which seemed a little early for a baby to have matured to this size. When we looked through the binocs we were really stumped. The "baby" had the breeding plumage of an adult. I know males can be a little bigger than females, but this strange couple must have been made up of the biggest of big males and the smallest of small females...

...when we watched this couple from the bank, the size difference seemed much larger than what was captured in the photo, but even here, you can see how much bigger the male was. The female really did look like a juvenile. I don't get to see breeding pairs very often. I usually only see single birds when they are migrating through and floating solo, so maybe this is a normal size difference.

...we saw this Pied-billed Grebe couple at the J.N. Ding Darling National Wildlife Preserve earlier this year in March.

...pencil sketch of the mismatched Pied-billed Grebe couple (the size difference is slightly exaggerated in the sketch, but in real life, the male looked much larger as appears in this sketch--compared to how he appears in the photos).

After I painted the painting, I took a spray bottle and sprayed the whole thing, letting the colors mix and drip down the page. It was painted quickly and sprayed before the paint had totally dried.

...more bird paintings

Painting 157, Prairie Warbler
(Watercolor heightened with colored pencil)

I saw this fellow back in March at Ding Darling. He sang nonstop and came in incredibly close for me. I fell in love with him...

Painting 156, Great Blue Heron
What Big Yellow Eyes You Have...
(Watercolor)

...this beautiful Great Blue Heron fished and walked the beach daily near our condo on Captiva Island, Florida. He's also the same Big Blue that showed up in painting 135, A Captiva Blue in Green.

Painting 155, Great Blue Heron
Grunge in Florida Light...
(Acrylic)

...the same fellow that's in painting 156, but I painted this version with a palette knife and very thick acrylic. The painting was too large for the scanner (16x20), so I photographed it. Unfortunately, it was a grey day and the photo is way too dark, not doing the painting justice. I need to rephotograph it when the sun returns....

Painting 154, Common Yellowthroat Hiding Along the Little Miami River
(Watercolor underpainting covered in oil pastel)

(the original Common Yellowthroat watercolor painting)

The original watercolor didn't have enough life in it for me, so I gave in and smeared color all over it, losing the leaves in the process...

Marbled Godwits on the mudflats of Ding Darling...

Birding Sanibel Island and the J.N. "Ding" Darling National Wildlife Refuge
...standing on Wildlife Drive and looking out at the mudflats of the eastern impoundment in the Ding Darling NWR, a huge flock of Willets flew in causing quite a stir. Through the binocs, Matty and I could see a few Short-billed Dowitchers were thrown in...and a life bird for us, a Marbled Godwit (Limosa fedoa)...

...a Marbled Godwit towers over the Short-billed Dowitcher standing beside it in the water.

...fluffing beautiful, carmel-colored feathers.

...there is no missing that long pink bill with the black tip! It's beautiful...

Marbled Godwits are stunning birds. Large and impressive, their pinkish bills really stand out, and their warm colors separate them easily from the surrounding grey-colored birds.

...a glimpse of the "cinnamon flash" of the underlining of the Marbled Godwit's wing. I was surprised how noticeable it was.

...two Marbled Godwits stand among Willets and Short-billed Dowitchers, their slightly upturned pinkish and blackish bills stealing the show!

The Dance of the Reddish Egret

Birding Sanibel Island and the J.N. "Ding" Darling National Wildlife Refuge
A soft breeze was pushing across the shallow waters of the eastern impoundment of the tidal basins off Wildlife Drive in the Ding Darling NWR, ruffling our hair and providing cooling relief from the ever-strengthening sun overhead. It was quiet, and an adult and juvenile Pied-billed Grebe were bobbing and preening in the shallow saltwater tidal flats on the right side of the rode--the Pine Island Sound side. Matty and I were crouched in shaggy grass behind a small red mangrove stand watching the two birds, captivated by the baby as he dove every now and then under the water only to pop up nearby, water beading and dripping from his dull brown feathers (just like his mama!). Eventually, however, a bird on the other side of the drive--the eastern impoundment side, which is the brackish freshwater basin, stole our attention and pulled us across the road and into the breeze. "What is that bird doing?" Matty asked. "Dancing!" I told him, "...and fishing..." Matty had spotted one of the birds I wanted us to see most that day, a Reddish Egret (our rarest egret), and even better, the reddish-bluish bird with a half pink and half black bill was doing his famous dance!

...a Reddish Egret runs in circles and "dances" through the shallows of the eastern impoundment along Wildlife Drive at Ding Darling. He's not just having fun...or running away in terror from an alligator, he's employing the same foraging techniques used by his ancestors for centuries.

A Reddish Egret raises its wings to form a canopy over the water, casting a shadow that reduces the sun's glare, making it easier for the bird to see the fish in the water. The shadow also lures in small fish and frogs, tricking them into its "protective" shelter.

...prancing and hopping around in the shallow water with wings outstretched and flapping, running back and forth in his own ballet...all to drum up a little lunch!

...every now and then he pauses from the dance and assumes the canopy stance...luring in the unsuspecting prey churned up from his spastic movements. He also may shuffle his feet a bit to stir up the mud, releasing other tasty creatures.

...flicking the wings...and prancing....

...more flicking of the wings...and prancing...

...charging through the water... (These shots always make me laugh. It looks like he's shrieking in the stereotypical "I just saw a mouse" posture...or maybe the standard, "snake...")

...getting ready...

...direct hit!

Matty and I saw this bird on March 22, 2011. For last year's visit to Longboat Key, Florida, and another post on the Reddish Egret's fishing dance, click here.

Dunlins hunting in the mudflats...

...from the Captiva Island, Florida posts.
Birding Sanibel Island and the J.N. "Ding" Darling National Wildlife Refuge
While two little Dunlins were busy scouring the muddy shores of one of the salt-water marshes and mudflats in the Ding Darling NWR, Matty and I were watching a Reddish Egret hunting and dancing in the blue waters much farther out. We didn't even know the two "best buds" were so close until we happened to look down. A total surprise, they were about 15-20 feet away, systematically probing the soft, creamy mud for invertebrates...

...could these little sandpipers be any sweeter? I love Dunlins with their gently down-curving bills and their beautiful little faces.

Although still mostly garbed in his dull, "dun," non-breeding winter colors, the beautiful russets and reds of his spring breeding plumage are starting to show.

Dunlins are predominantly visual hunters (pecking) during the day and tactile hunters (probing) at night. Matty and I sat on the grassy embankment and watched the Dunlins for a long time. We saw both feeding methods. Maybe because the mud was so soft and creamy they did a lot of tactile feeding, their long bills resembling straws that let them probe deep into the muck and slurp up their prey!

Click here to read a very interesting article about the Dunlin's hunting methods in the Journal of Avian Biology 25: 55-62 by K. N. Mouritsen titled, "Day and night feeding in Dunlins Calidris alpina: choice of habitat, foraging technique and prey."

I don't think this is the Stink Eye. I think it's a curious What's-making-that-clicking-sound-above-me Eye!

Matty and I watched these birds on March 21, 2011. It was so warm in the Florida sun, and we were able to sit down, relax and just study the little birds. Such a welcome relief from the cold, nasty weather still waiting for us back home...

Usually when we saw the Dunlins at Ding Darling, they were in huge mixed flocks out on the mudflats, but these two birds were hanging by themselves. Sometimes they would split up for a few minutes, but they always came back together. At one point, we were further down the road watching a Tri-colored Heron, when a large flock of Dunlins ripped over our heads trailing energy, sound and even a breeze in their wake. It was so sudden and unexpected--and the experience was made even more thrilling because they flew from back to front and only a few feet over our heads. It was like all the energy of their flock washed over us. In a split second they were in front of us zipping and turning together at breakneck speed, flashing and zig-zagging until they lighted on the mudflat further out in the marsh. It was the first time I ever felt that kind of energy...I'll never forget it.

P.S. After dinner this evening Rick and I headed over to the Little Miami River to see what neotropical migrants we could find, and...oh my gosh...first up was a Canada Warbler!! He was so gorgeous...and SO CLOSE...and stayed around for so long. Even Rick the Reluctant Birder was sold. We then saw a Black-throated Green Warbler, a Blackburnian Warbler, two Wood Thrushes, two Hermit Thrushes, a Swainson's Thrush! (directly overhead), an Ovenbird (really, really close too)...our Northern Parula was still there, a Baltimore Oriole, Red-eyed Vireos...tons of Blue-gray Gnatcatchers, two Phoebes...an Eastern Wood Pewee...a Barred Owl...the list goes on and on. Rick attributes the incredible views of the Canada Warbler to the fact I didn't have my camera with me. It was misty...and foggy...and evening was falling hard, so I thought I'd be "free" and just bird with binocs. I knew not having the camera would guarantee something cool...

A Cormorant taking off from the water...doing the Cormorant Hop!

...back to the Captiva Island, Florida posts!
Birding Sanibel Island and the J.N. "Ding" Darling National Wildlife Refuge

Cormorants are always fun to watch. I like to follow them when they are diving for fish, but watching their take-offs is sometimes even more entertaining. They don't pitter-pat, pitter-pat, pitter pat across the water in a running motion before eventually hauling their stout and dripping wet bodies out of the water and into the air--they hop, hop, HOP!


A Double-crested Cormorant swims the waters of the Ding Darling NWR.
His sparkling turquoise-colored eyes and orangish face mask command attention...


...hmmmm...that water looks like it's starting to boil. Something must be going on with those feet!


SPLASH! Cormorants use both feet at the same time to push off the water when they are taking off, basically hopping their way in huge leaps across the water. If you follow the splashes you can see this fellow's progress...a big splash, then undisturbed water, then another big splash, etc. (One of my favorite bird reference books is the National Geographic Reference Atlas to the Birds of North America by Mel Baughman. I like this book because is discusses bird behavior and general information instead of bird ID. You can read more about the cormorant's take-off method in this book.)


...the hops are getting further apart...and you can see his two feet working together!


...do we have lift off?


...no, but almost...one more really big hop should do it...


...see you later C-bird!

...these photos were taken on March 22, 2011 at the Ding Darling NWR on Sanibel Island, Florida. It was so beautiful...warm, sunny, and blue!
