bug on daisy

I was admiring the daisies.  A Squash Bug was also admiring it, close up!  

dragonflies

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.

goslings

A Canada Goose family had lunch on the pond today. The adults, one in front and one behind, led the 5 young goslings to find food.  The young are able to feed the first day they hatch out of their eggs, and eat the same as adult gooses - - green vegetation and grains, small insects and fish.  Like many water birds, Canada Goose Branta canadensis are susceptible to the dangers that humans have created, like this plastic netting caught in the beak of one gosling.

On closer look, one of the young geese struggled with a piece of plastic netting caught in the hinge of its bill.  The gosling was able to keep up with the others but we wonder about its future health. 

mallow

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.

One of these tiny weedy wildflowers is Common Mallow Malva neglecta, with 5 petals of palest pink with stronger pink stripes. 

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.

northern blue flag

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.  

white campion

White Campion Silene latifolia is blooming now. 

robin

Robins nesting by the pond have 4 eggs in their nest.  The female gathered food items on the shore while taking a break from incubating her clutch.  It looks like she caught an insect larva, but Robins also eat grubs, snails, spiders, beetles, grasshoppers, termites, crickets, and other insects.

golden alexanders

Wildflowers are blooming in the pond area.  Zizia aurea Golden Alexanders feed bees, wasps, flies, and beetles with pollen and nectar.  The larvae of some butterflies also feed on this native plant.

green heron

This is the first time we've seen a Green Heron this year.  Last year, posts on this blog showed the Butorides virescens several times --  describing what they eat, how they hunt for food, and how they use tools.  (see posts on 7-09-2020,  7-15-2020,  and 9-8-2020.

Green Heron is a small bird, usually 17 inches long.  When stealth is necessary, the neck is pulled in towards the body, but this bird pictured has it out half-way. It can extend the neck even longer to snap up prey.  Adults have a glossy, dark greenish iridescent cap, a greenish-grey back and wings, a chestnut neck with a white line down the front.  Legs are yellow, and the long bill has a sharp point. 

hooded merganser ducklings

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.

mallard ducklings

 Mallard drake wants to keep an eye on his family.

bee swarm

On Friday, we noticed a blob of brown on a drooping branch on one the pine trees near the pond.  Close inspection revealed hundreds of Honey Bees clustered. The next day they were still gathered around that branch. We discovered with some research that when overcrowded in a hive, bees with divide their population then some will set out for a new hive. Scout bees look intensely for the new nest while the most of them wait together.  This probably saves energy and protects them by staying together in one place while the scouts scout.

By Sunday morning they had all gone from the tree branch, no trace left behind of their weekend stay.

convivial Merganser

Today the convivial Merganser shared the favored rock in the pond with a turtle.

The Hooded Mergansers  Lophodytes cucullatus have visited the pond several times in the last few weeks. We saw both females and males, usually in groups, and assumed they were probably stopping for rest or food while migrating. They are nicknamed 'divers' since they dive to feed on items under or in the water.

A few days ago, I noticed a single female Hooded Merganser lazing on the pond close to a male Mallard.  Neither seemed to be bothered by the other. She dived in deep water for food, he dabbled in shallow water for a snack.  They sunned themselves together all day long, complacently napping while floating in the sunshine.

The Mallard has been hanging around for weeks while his mate sits on her nest of eggs. Sometimes we see the pair of Mallards together when the female comes out for meals; they dabble together on the shores.  That day, the Merganser was happy to float with one or both.  This afternoon, she was again present and just as friendly to the turtle who had been sitting on the rock since morning. What a friendly neighbor to all.

blue-winged teal pair

The pair of Blue-winged Teal ducks were feeding on the pond this week.  They usually nest on the ground after the female selects a spot. She looks for a place near water with grass cover to hide her eggs.  

This pair of Teal Spatula discor  dabble to search among the reeds for something to eat.

Like many bird species, the female is drab speckled brown for hiding among grasses while nesting.  He is decked out for courting in colorful cinnamon front, speckled sides, black head with a white crescent on each side. Both have blue feathers on the wings which are displayed when they fly.
 

fox sparrow

A chunky long tailed Fox Sparrow Passerella iliaca posed for the camera by the pond.  It is probably migrating to breeding grounds north of here, and stopped to snag some seeds or insects here.

phoebes

Phoebes, in the flycatcher family, arrived on the pond this week.  They went to their favorite 'jumping off place' to watch for and catch flying prey just above the water.  We watched them last summer -- every day sitting on the concrete outflow weir.  Each would fly down to the water, gobble the airborne insect, and take it to their nest where hatchlings waited for food.  I hope they nest here again this season!
 

spotted sandpipers

A flock of shorebirds stopped today at the pond on their migration trip.  Spotted Sandpipers Actitis macularius, catch food in several different ways.  Like most other sandpipers, they probe into sand or mud with their bills looking for food -- aquatic larvae of insects, beetles, worms, snails or crustaceans.  And like herons, they also lunge at moving small fish in the water, pick insects off plants, or snap at flying prey.

basking turtles

Many Painted Turtles Chrysemys picta live in the pond. On sunny days they climb out of the water and bask in the sun to warm their blood.  In this temperate Spring weather, they spread all their appendages including head and neck out of the shell to get maximum exposure.

blue-wing teal

Some waterfowl, Blue-winged Teal Anas discors, stopped on the pond today.  They are some of the last ducks to arrive each Spring on breeding grounds because of their long migration from South America or Mexico. Smaller than Mallards, each weighs 9 to 18 ounces. They feed by 'dabbling' for plant matter under the water, or for crustaceans or insect larvae in the water.

tree swallow, first of 2021

Migration brings something new each day!  We saw several Tree Swallows, actively aerial hunting over the pond for any flying insects they could eat.  One checked out the nestbox where a pair raised a clutch of eggs successfully last year.  They moved on, but the box is ready in nesting season for Bluebirds or Tree Swallows making their way here.

dove on rock

The Mourning Doves Zenaida macroura spent winter near the pond in nearby bushes and tree cover. This one is celebrating Spring by investigating the water and rocks in the pond. 

Its bright pink-orange feet made it through another cold season by the 'wonderful net' of arteries. This adaptation interweaves blood vessels from and to the heart so birds don’t lose much heat through their feet. Read more at

golden alexanders

Many native plants are coming up through their winter blankets of grasses and mulch.  The Golden Alexanders Zizia aurea will be displaying their golden yellow flowers in just a few weeks.

hooded mergansers

Hooded Mergansers Lophodytes cucullatus are the smallest of the three native Mergansers. They migrate in early Spring along the Mississippi River and arrive on breeding grounds as soon as the ice is melted.  On this pond, they rest and find nourishment in aquatic insects, crustaceans, amphibians, and vegetation.  Pairs form in winter and they will find a tree cavity or wood duck box to built their nest.

tamarack rosettes

There are several trees in the riparian area around the pond.  One is the Tamarack Larix laricina or American Larch.  It is just starting to flower, before sprouting its fresh bright green soft needles. Tamarack is a native deciduous conifer; it is in the pine family but sheds needles (leaves) in Autumn.

lovey doves

Mourning Doves being lovey-dovey.  A small flock has been here all winter, coming to the feeders for nourishment. These two hang together now since it is mating season. One was feeding the other a morsel, a sure sign of courtship.  The male of this species is slightly larger than the female, and he has a pink chest.
