I guess I’ll just change the name of this blog to the Indian RiverSide Park Pond Blog.
But you can see why I go there: I watched all these birds while sitting cross-legged in one little spot on an ant-free patch of grass, with my German Shepherd in a down-stay beside me.
A birdy place in the not very birdy season of Florida summer. And within my 5-mile radius.
This photo is like a natural history museum diorama of wetland bird life!

They had no problem sharing space. I took these photos Friday around 7 p.m. The park was busy, including a softball semi-final game with extra cars and people.
A male Mottled Duck, Anas fulvigula, with a bit of blue secondary feathers (wing patch, speculum) showing on the wing.
The ibis was the busiest, probing here and there, and the duck the least busy, standing with zen-like calm.
The ibis was carrying a little minnow around for a while.
Such a diversity of water loving birds here in wet Florida.
The Black-bellied is quite a different looking duck from the mallards and mallard-like Mottleds I see regularly. And funny that it is standing in the water.
Two very different bird beaks.
The beak, bill, or rostrum is an external anatomical structure of birds that is used for eating and for preening, manipulating objects, killing prey, fighting, probing for food, courtship and feeding young.
Neat illustration on Wikimedia Commons.
The Tricolored Heron is a sleek and slender heron adorned in blue-gray, lavender, and white. The white stripe down the middle of its sinuous neck and its white belly set it apart from other dark herons. This fairly small heron wades through coastal waters in search of small fish, often running and stopping with quick turns and starts, as if dancing in a ballet.
And stabbing them with its beak, en garde! A little fencing heron.
You can see the tip of the Black-bellied Whistling Duck’s beak turns down a bit at the end. That part is called the nail…
All birds of the family Anatidae (ducks, geese, and swans) have a nail, a plate of hard horny tissue at the tip of the beak. This shield-shaped structure, which sometimes spans the entire width of the beak, is often bent at the tip to form a hook. It serves different purposes depending on the bird’s primary food source. Most species use their nails to dig seeds out of mud or vegetation, while diving ducks use theirs to pry molluscs from rocks. There is evidence that the nail may help a bird to grasp things; species which use strong grasping motions to secure their food (such as when catching and holding onto a large squirming frog) have very wide nails.
An ibis beak has a special addition.
The bill tip organ is a region found near the tip of the bill in several types of birds that forage particularly by probing. The region has a high density of nerve endings known as the corpuscles of Herbst. This consists of pits in the bill surface which in the living bird is occupied by cells that sense pressure changes. The assumption is that this allows the bird to perform ‘remote touch’, which means that it can detect movements of animals which the bird does not directly touch. Bird species known to have a ‘bill-tip organ’ includes members of ibisis, shorebirds of the family Scolopacidae, and kiwis.
This young ibis was carrying this little fish around a for a while.
Not sure what it was waiting for to gobble it up.
The colors of the juvenile White Ibis are a nice gray brown.
When baby White Ibises hatch their bills are straight. Their bills don’t start to curve downward until they are 14 days old.
Wow! Maybe so they can break out of the shell?
New vocabulary word…
The speculum is a patch of often iridescent color on the secondary feathers of most duck species. It is often seen as a bright patch of color on the rear of the wing when the wing is spread during flight or when the bird is stretching, preening, or landing. The color of the speculum will vary by species, as will its width and any non-iridescent borders.
The other duck’s wing patch is off-white and looks like a stripe when the wings are at rest.
The Black-bellied Whistling-Duck is a boisterous duck with a brilliant pink bill and an unusual, long-legged silhouette. In places like Texas and Louisiana, watch for noisy flocks of these gaudy ducks dropping into fields to forage on seeds, or loafing on golf course ponds. Listen for them, too—these ducks really do have a whistle for their call. Common south of the U.S., Black-bellied Whistling-Ducks occur in several southern states and are expanding northward.
The Tricolored Heron is petite compared to the big ones I photograph all the time.
Like this Great Egret a short distance away, owning its spot by the pond.
What our juvenile White Ibis will look like when he’s all grown up.
They look like a flock of bird ghosts, spooky and cute.
