sora, master of disguise

My new favorite bird!  I just discovered the Sora Porzana carolina (a very secretive wetland bird) this Spring.  I watch a pair every day, hunting at the edge of the pond.  They think the mottled-pattern camouflage feathers makes them hard to spot.  But the bright yellow bill gives them away.   (see post on 4/24/2022)

blue-winged teal

Blue-winged Teal ducks have been on the pond for a week or so. Last year, this species stayed only a few days to rest on migration. This season, they seem to find enough food here to stay longer. The hen makes a nest on the ground where she finds grassy cover to hide her eggs from predators. I admired the male's feathers, especially the white chevron on the back of his head.

Sora

This very secretive bird, that usually hides among vegetation, today revealed itself at the edge of the pond!  I hope this one will find a spot to nest among the dense vegetation of rushes and sedges.

Not often seen in the open, the Sora is a small chubby bird of freshwater shallow areas with plants such as cattails, sedges and rushes.  Sora Porzana carolina is brown and gray with a mottled patterned body, 8-10" long.  Despite their camouflage feathers, the bright yellow bill gives them away.  It is stubby, thick, glowing yellow in a gray face with black mask.

Soras feed by pecking at the water surface for seeds, aquatic insects, or invertebrates. Long toes help them to rake through submerged vegetation for food items, and help them walk on floating mats of plants. They nest among dense plants at the pond edge.

dabblers and divers

The pond area is bustling with birds arriving! Several species of ducks have stopped for a meal or a day of rest on migration.  I marvel at how they tolerate one another in this small spot of respite. Occasionally we hear honking or see disputes, but mostly the creatures get along.  

Animals have adapted their method to feed in different ways.  For instance, we saw Mallards feeding near Hooded Mergansers. Mallards and Blue-winged Teal are ‘dabblers' – they dip their beak and head into the water to munch on shallow-water plants. Mergansers are ‘divers' – they dive totally under the water to eat plants growing in deep water.  

hare

The pond has been under a comforter of white snow. The snow layer insulates and protects the critters tucked in among the rocks, mud, and dormant plants below water and ice.

On a sunny day, we saw a large rabbit sitting in the snow near the pond. It created a depression in the snow among reeds and wildflower stems, and snuggled down there all day. At dusk, it was gone from that spot. The next day the sunshine was bright on the white snow. The rabbit was in the same spot again, and napped all day. I suspect it was a White-tailed Jackrabbit Lepus townsendii, actually a hare.  Jackrabbits are nocturnal hunters and are known to take daylight naps in a shallow hole. 

muskrats chasing ducks

As the Mallards swim around the pond, feeding on plants growing at the edge, the muskrats chase the ducks.  The water mammals don't want to share with the birds. Muskrats' burrow or tunnel system is nearby, with an underwater entrance.

mallards showing off

After a month of no ducks on the pond at all, there have been many Mallards feeding and napping here. They are gathering to prepare for their fall migration. Mallards can indeed survive cold weather, but when they can no longer feed on live aquatic plants, insects in the water, or grain in snow-covered fields, it is time to fly south.

Each day in Autumn they search for food around the edge of the pond, nap in the warm sun, or practice their courtship moves. Mallards engage in seasonal monogamy, in which new pair bonds are formed each season. Usually they form these bonds on their wintering grounds.  And with new handsome feathers after molting season, why not show off?

Some of the courtship displays by Mallards are rhythmic head-pumping, signaling interest. Males will show off by pulling both wings and tail up to show off purple-blue wing feathers. Or, the male will raise out of the water, pull his head up, and give a whistle (as above).

pond lily

How nice to have a pond lily! We anticipated seeing it bloom next season. The little plant was happy in this pond, spreading out its leaves to soak up the sun and give the tuber in the mud oxygen through the underwater stems.  

Then, ducks landed on the pond . . .  and ate the leaves and stems.  We'll see next Spring if they ate the roots too.

log

 Every pond needs a log for turtles to sit on while sunning themselves.

It will probably be used by birds hunting aquatic prey, damselflies drying their wings, and frogs.

blooming water plantain

This summer, scant rain fell in July and August. The pond suffered lower water levels as each day passed.  

Eventually, some aquatic plants that grow at the edge of the pond stood in mud rather than in shallow water. 

But the Northern Water Plantain Alisma triviale thrived despite the drought.  It sent up stems more than 2 feet high on which many whorls of white flowers opened, each about 1/4" across.

strong stem

The strong stiff stems of Ironweed are known for proudly holding flowers, pollen, and nectar above the other native plants. Butterflies, bees, and other insects find Vernonia fasciculate, ‘Prairie' or ‘Common' Ironweed plants, a source of nourishment.  This plant also helps filter water that percolates back into the soil. That means less toxins in water that recharges the groundwater aquifers.

Ironweed is one of a few host plants for American Painted Lady butterfly. ‘Host plants’ are those that the butterfly lives on, lays eggs on, and their larvae are sustained by.

blue lobelia

Blue Lobelia, a native perennial, started blooming several weeks ago in the wetland around the pond.  Each spike of flowers opens from the bottom up.  This plant Lobelia siphilitica is related to the intense red Cardinal Flower Lobelia siphilitica.  In fact, sometimes Blue Lobelia is called  Blue Cardinal Flower.  It should bloom until frost, now that we received some rain after a dry summer. 

arrowhead blooming

 

Among the plants along the shore of the pond, Arrowhead Sagittaria latifolia plants hold their leaves pointing skyward above the water.

This week, we noticed they are blooming with white, 3-petaled flowers held up above the leaves on strong branched stems. 

Each flower is about 1" across.

This variety is specifically Broadleaved Arrowhead; also called 'Duck Potato' since it is a perennial plant that forms food-storing tubers as roots. 

blue vervain

Blue Vervain Verbena hastata blooms among the green grasses and rushes around the pond.  

It likes wet feet, so grows close to the water.  

The flowers open slowly over several weeks from the bottom up on a cluster of stems.

gleeful painted turtle

The painted turtles who live in the pond love to sit in the sun, especially on rocks near the water. There, each can enjoy the warmth and (in case of danger) slip into the water to hide if needed. This young little critter, about 4 inches long, looked so gleeful today with its feet extended out to catch as much sunshine as possible.

scouring rush

Scouring Rush Equisetum hyemale grows in the wetland around the pond.  It is also called 'horsetail'.

This plant's ancestors have been on earth millions of years.  

The tough stems can be used as reeds for musical instruments.

They also have coarse fibers and silica deposits, so mammal herbivore don't eat this plant.  

Rather than seeds, the Scouring Rush reproduces by spores made by structures on the top of each fertile stem.
