new feathers


In November, Mallards paddle on the pond before they migrate to warmer places. The male Mallards molt their feathers in the autumn and regrow their green head feathers; in the following spring brilliant colors will help each male find a mate for the next breeding season.

Crows gather in massive groups to roost together at night so they can share warmth and safety from predators. It is believed they even exchange information about food and weather fronts.

heat wave in October


70+ degrees F. !!  Wonderful autumn weather.

first snow 2022

Snow overnight. The log is totally exposed, because we are down more than 8 inches of precipitation.

canada milkvetch


 

Seed pods of Canada Milkvetch are beginning to dry enough to spill the tiny seeds.  In the background is the ubiquitous white asters that grow everywhere among native wildflowers at this time of the year.

leaf galls

This fallen leaf has galls all over it, lumps or complicated structures that look like capsules containing something mysterious.  Galls are made by one of 1500 species of gall producers -- mostly insects and mites.  Some galls form on leaves where insects feed on the plant matter, or lay eggs.  Galls may also develop as a response to infections by fungi, bacteria, or viruses.  Dissecting the gall is the only sure way to tell what caused it. That's a whole different adventure!

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).

black birds roosting

Flocks of blackbirds gathered to roost for the night in the big cottonwood tree far across the pond.  
Now that birds are finished defending their nesting territories and raising young birds, they begin congregating in really large flocks to feed and protect one another from predators like owls and hawks. The birds gathering may be a mix of Red-winged Blackbirds and Starlings, Cowbirds, and Grackles.

mushroom




Shaggy Mane, the white mushrooms that seem to appear overnight when we have cool damp weather.  Also called "Lawyers Wig", both names invoke the hairy scales its botanical name defines Coprinus comatus (coma is 'hair').

golden alexanders, golden in autumn


 

Among the yellow, purple, and white flowers in the riparian area surrounding the pond, the Golden Alexanders Zizia aurea have long gone to seed.  

They bloomed a sunny yellow in May and June. Now, the seeds still stand in umbels on strong stems.  The entire plant material remaining turns a golden purple-tinged color -- lovely among the autumn asters.

seed harvest

 


Birds are already pecking out the sunflower seeds (top) and goldenrod flowers are releasing each seed with pappus, a tuft of hair that helps it disperse in breezes (bottom).

temperamental autumn


Autumn and Spring are the transition seasons, temperamental and transformative.

In past years, I’ve watched birds arrive for nesting on their sacrosanct schedule, whether driven by daylight hours or other clues. Some years, they arrive in Spring when weather is fine, start building nests, and then have to endure several days of cold rain or snow. 

So it is with Autumn.  In October this year, we endured a week of early winter with extreme cold air and several inches of snow.  

But then we had this delightful first week in November!  Sunny and warm until today.

sparrow feeding on shore

Evidently there are still damselflies or dragonflies among the reeds and grasses on the shore.  This sparrow scored one while hopping in the shallow water of the pond.

surviving below freezing - turtles

Since we had several cold days and nights already, Painted Turtles Chrysemys picta who live in the pond are getting ready for winter.  Lacking summer heat, this one was wandering very very slowly for a food item or a place to settle. Turtles will spend the next several months in frigid pond water below the frozen ice, with their metabolism and their heart rate slowed way down. They can absorb oxygen from the water through vascularized areas in their mouth, throat, and anus (cloacal respiration).  But using oxygen produces lactic acid in their body, which the turtle counteracts with minerals released from its shell and bones.  Painted Turtles do not eat during this time, but they do remain alert, especially to light from above.  In Spring, when the hours of daylight increase, they will respond.

seed heads

 

I have been wandering the riparian buffer and clipping some of the wildflower seed heads to distribute them around the pond. Some native wildflowers exist here already, and we want to spread desirable plants throughout the buffer. 

The clipping process is "a few for spreading to make new plants, most left for the birds." 

Even after the seeds are gone, the structure of the plant is interesting!

boneset in autumn



Boneset Eupatorium perfoliatum has a stout hairy stem, and the plant's leaves occur along it opposite to one another.  In autumn, the flowers go to seed, and leaves turn a rich red-brown color.

The leaves are described as 'perfoliate' because each joins the opposite leaf around the stem so it appears the stem grows through one large leaf.  All parts of this plant are toxic and bitter. Birds rarely eat the seeds, but are attracted to the flowers for the many insects there.


10/16/2020

Mallards have been feeding and sunning themselves all day on the pond, even though we had a few snow squalls.  They must be getting ready to head south for the winter.  At dusk, the muskrat came out to gather a meal.  Seeing the ducks, he swam towards them again and again, trying to chase them away.  Defending his territory, or maybe since it is autumn he does not want to share the dwindling green plant material left to eat in the pond?
