nest box peek

Peeking into the nest box . . . 

Tree Swallows lay eggs and 
disguise them by sticking feathers 
barb-down so the fluffy vanes curl over the contents of the nest.

In this photo, we can see a few white eggs among the soft grasses in the bottom of the nest box.
 

phoebe

Rainy cold day for flycatchers!  These two Eastern Phoebes Sayornis phoebe rested on the branch and spent several minutes to shake their feathers and preen feathers. Maybe they look bedraggled because they were hunting flying insects in wet weather. 

nectar and pollen

Before June, dandelion flowers are one of a few important food source for pollinators, providing both nectar and pollen for bumblebees and honey bees. Other various insects like beetles, hoverflies and butterflies use the nectar as food. Some birds eat the seeds. 

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)

strutting blackbird

 The blackbird was foraging among the short grasses near the pond.   A female, recently arrived after migrating, landed on a branch of swamp willow.  The male saw her and started displaying his handsome epaulets.  He walked toward her with his feathers fluffed out and tail partly spread.  As he proceeded, he lifted the leading edge of each wing so that the red shoulder patches were puffed up, appearing bigger.  She flew to another small tree; he followed among the willow sprouts, displaying his male beauty to impress her. 

(Red-winged Blackbird males have colorful upperwing coverts of red bordered with yellow on the bend of each wing.  He will use the colorful display to threaten other birds, defend his territory, or attract a mate.)

muskrat claws

 

Often we can see a muskrat swimming back and forth in the pond, harvesting plants and taking food home to the family.  Muskrats Ondatra zibethica eat the roots, stems, leaves, and fruits of many water plants such as cattail, rushes, smartweed, duck potato, horsetail, sedges, and willow sprouts.  They are strong swimmers due to their two long back feet and five webbed toes.  For grasping and harvesting food, they have developed smaller front feet with four fingers with claws and a small thumb.   By living near the pond, muskrats control plant growth, provide open spaces for new plants to grow, and make space for other animals to build their nests.

sandpiper

Spotted Sandpiper has again migrated north to Minnesota. This species spends winter as far south as South America.  Welcome back!

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.

green sprouting

 After a late, cold and windy Spring season, there is finally some green leaves sprouting in the wetland surrounding the pond. These are the beginning leaves of Golden Alexanders.

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.

crow on rocks

The rocks scattered around the pond are revealed as the water level changes with rain or drought. It is always interesting to see what critter might rest, sun itself, or defend (for a moment) a particular dry rock.

This crow was trying to fetch seeds from the water surface by standing on two rocks.

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.  

ducks on log

Hooded Mergansers Lophodytes cucullatus appear prominently on the pond when the weather is nice (you can not miss their dazzling appearance and active diving), and they disappear from view when it is not nice. This year, April has been colder than normal, rainy, and with mostly gray skies.

Waterfowl like these are here on their nesting ground. They can find shelter from bad weather in the weeds and reeds around the pond.  This Hooded Merganser pair can find plenty to eat here . . .  small frogs, tadpoles, insects, seeds, and even the roots or bulbs of water plants.  When they're satisfied, the pond offers several exposed rocks, logs, and shallow bars for critters to use as loafing sites. 

Next up -- finding a nesting site.

silly gooses

Canada Geese Branta canadensis occasionally visit the pond, but we discourage them from gathering here.  This is a small community pond and not able to support a flock of geese.

This pair has been hanging around for a week, honking at the ducks. This morning they decided to stand on the roof to get a better view. We love seeing the goslings (see 6/10/2021 goslings), but geese in large numbers can be pests.

 

muskrat whiskers

The muskrat Ondatra zibethicus was gathering breakfast this morning near the pond. 

He has a short soft underfur that traps air for insulation and buoyancy, and with longer stiff guard hairs over the underfur.  The whiskers stand out from the face.

Their tails are 7 to 11 inches long. No fur here . . .  the tail is covered in scales.  When they dive to move around, the tail is flattened vertically and serves as a rudder.

 

eagle nest, March

The eagle nest near the pond has been a quiet site while the birds wait for eggs to hatch. 

We can see a white head of the Bald Eagle Haliaeetus leucocephalus sitting in the nest.  Since she is hunkered down in the 'bowl' the pair formed among the branches, the eggs (or young, if hatched) cannot be seen from the ground.

robin likes suet

 

This bird has been coming to the suet feeder near the pond for several days. American Robins usually eat insects, invertebrates, and berries.  This suet has seeds in it. They must be tasty to the Robin.

'homing' Mallards

Mallards can stay through winter in Minnesota if they can find food near open water. Now that the solid shore-to-shore ice on the pond is melting, a pair showed up here. This is probably the same pair that nested near the pond last year, since Mallards are known to 'home' where they have nested previously.

Even though a fractured layer of ice floats nearby, these ducks find food beneath the water. This might be what is known as a 'cold lunch'.

color

A tiny bit of color inside!  

Outside -- among the vast white of the snow on the pond -- the Goldfinches, rose colored House Finches, and red caps of the Woodpeckers.

icicles

March this year promises to be, as usual, a roller-coaster of weather. 

Rain turned to sleet overnight as the temperature dropped.

This morning everything outside was coated with icicles, including bird feeders near the pond.

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. 

eagle nest, January

The eagle nest near the pond is again claimed as home for a pair of Bald Eagles Haliaeetus leucocephalus. One was in the nest for a while before this, probably rearranging sticks to her liking in preparation to lay eggs.

FeederWatch, Downy Woodpecker

 

FeederWatch, a citizen-science program of Cornell University Lab of Ornithology, is once again an activity for me through the cold winter months.  This small Downy Woodpecker Dryobates pubescens comes every day to feed at the suet block hanging near the pond. Suet supplements his regular diet of insects which he searches for between folds of tree bark. His tail feathers are strong and positionable to support him on tree branches or wherever he finds food.

new year 2022 Juncos

Dark-eyed Juncos made their sudden winter appearance several weeks ago.  In Springtime, they find mates and nest "up north" in Canada.  In Autumn they migrate to places across the US where they spend the colder months. Junco hyemalis are flashy little sparrows. I think they look as if they're wearing tuxedoes, with crisp markings -- a white chest and belly, dark gray or black back, and pink bill.  They have bright white tail feathers which they reveal as they flit around on the ground searching for seeds. Juncos flock together in winter, sometimes with others species. When they find a stash of seeds (like this dish on the deck overlooking the pond) they grudgingly takes turns at it.

stars on ice

Another interesting feature of winter on the pond is the 'ice star'  or 'lake star'.  In my search for information about these patterns, I found many theories -- all related to the physics of temperature, moisture, pressure, and ice formation.  One of these theories is that patterns are formed in early winter when a hole allows water to swell up from beneath and spread over the surface, leaving dark fingers of melted ice radiating from the hole.
