Small yellow wildflowers, brightening the green grasses and rushes around the pond now, are River Loosestrife Lysimachia hybrida, or Lowland Yellow Loosestrife. This plant bloomed last year, and came back stronger with more stems this season. Lysmachias produce floral oil rather than nectar. These plants are also pollen hosts for Macropis bees; the bees specialize in using a mixture of pollen and floral oil to produce offspring. read more at U of MN Extension
Mallard female has been hiding her second clutch of eggs near the pond among grasses. Today she led all 6 hatched ducklings to the pond, where they paddled around and started to feed. They can eat seeds, stems, and roots of many different plants; also aquatic invertebrates such as worms, beetles, dragonflies, or insect larvae.
This dragonfly male 'Widow Skimmer' Libellula luctuosa shows off his handsome transparent wings with black and white structural coloration -- the production of color by microscopically structured surfaces fine enough to interfere with visible light.
The grass seedhead on the left is close to the camera and in front of the wing. But the rush stem behind the wing is showing clearly through the transparent wing while the skimmer rests, clasping that stem.
He is probably looking for prey -- other insects such as mosquitoes. To catch prey he will use his legs, and bring prey into his mouth with fangs.
Since this is a non-native invasive plant that can compete with native wildflowers, we will be removing it or cutting it back.
Once the flower blooms, it is a brilliant torch of yellow blossoms. Each blossom has 5 petals, and stays open for a short time. Thus, the spike may have only a few blossoms open at a time.
Green Herons nest in trees and shrubs near water, or dry woods and orchards as long as it provides seclusion and there is water nearby for foraging fish or frogs.
Last year we saw a Green Heron Butorides virescens several times here on the pond shore, hunting for a meal. To see those previous photos and information about how these birds use tools to hunt, enter heron in the search box at top left then press return.
Two large darner dragonflies hovered on pondweed growing in the water. Each dragonfly is over 3 inches long, and more brilliant blue and green colors than the vegetation nearby. They seemed to be connected (with the male grabbing the female by the head with his rear abdomen appendages) which suggests some stage of mating.
Small wildflowers grow in the riparian area surrounding the pond. Some are invisible to the casual observer because of their small stature, or because they are hidden by the many taller grasses and reeds.
The leaves resemble geraniums but the two families have different reproductive structures.
Mallow is also called 'Cheeseweed' since each seed looks like a miniature wheel of cheese.
Iris versicolor, the Northern Blue Flag, is blooming near the pond. It does not mind having its 'feet' wet and often grows in a few inches of water.
The blue to purple flowers stand out from the grasses and reeds around it, but the sword-like leaves blend into all that green!
This plant attracts both butterflies and hummingbirds, and may be known as Blue Flag Iris, Harlequin Blue Flag, Northern Iris, and Wild Iris.
Today the Hooded Merganser female showed up on the pond with 15 ducklings. This species nests in a cavity, probably in a tree or stump nearby. Once the eggs hatch, the ducklings follow the mother to water. They fed for a while, then she signaled them to rest. They followed her to shore and gathered under her wings. Well, sort of . . . there were many of them!
They dive under water to find small fish, amphibians, clams, mud crabs, crayfish, tadpoles, frogs, and aquatic insects and other crustaceans. They also consume some aquatic plants.
