October 1, 2019 - Fort Steilacoom

Today, I drove up to Fort Steilacoom Park for the monthly birders’ walk.  This outing takes place at the City of Lakewood’s 342-acre property, which has diverse habitats including open grassy hillsides with brushy areas, oak and other deciduous wooded areas, and coniferous Douglas-fir forest, all surrounding Waughop Lake.
Everyone wishes they could bird with a volcano on the horizon!
"Numerous" foot trails allow access throughout the park, which makes for some pretty good birding.

Russ Smith from Tahoma Audubon has led the group for several years, and tells us that birders have identified 146 avian species in the park.

This walk takes place every First Tuesday of the month, meeting near the Barns at 8 a.m.  Today, we were happy with - and give a well-earned Thank You! - to Mary Dodsworth, the Lakewood Parks Director and her trail crew for recently clearing several trails of downed limbs and trees, as well as grooming overgrown blackberry briars off other trails.

Today, was a bit chilly at first (38º F/ 3°C), but warmed up into a calm and sunny, mid-50º F day.  The wintering waterfowl haven’t yet arrived, but there were still a few “summer” birds hanging around.

An Oregon Ash tree was in full color, and while we were admiring it, sharp eyes (not mine) spotted a Western Tanager in its branches.

Later in the walk, we heard the soft “whoit” call of a lingering Swainson’s Thrush.  In our area the Hermit Thrush may be found year-round, while our population of the Swainson’s migrates to southern Mexico and Central America to enjoy its “winter”.

We were treated to a view of a male “Intergrade” Northern Flicker.  There are two ‘races’ of this woodpecker species.  Our common western subspecies, the Red-shafted Flicker, has a red malar patch or “mustache” and salmon-red primary wing feathers and rectrices (tail feathers).  The “Yellow-shafted” Flicker is the population expected in the eastern part of the country, although it breeds pretty far north (and west) into the Rocky Mountains, and has (as you’d expect) yellow flight feathers and a red crescent on the nape of  neck, as well as the male having a black mustache.  From Autumn through Spring, we can sort through the flickers, looking for “hybrids” between the two forms.  This bird was perched with apparent 'pure' Red-shafted female.  This male had red malars, no nape color, head/neck more cinnamon than gray, and distinctly bright yellow rectrices.

Another Autumn-through-Spring species is the Golden-crowned Sparrow, which, along with the Sooty Fox Sparrow, is one of the constant “little brown jobs” seen on our birding treks from now through April.

Hawks are apparently migrating, and we enjoyed seeing both the little Sharp-shinned and several of the larger Cooper’s Hawks.

The folks “in charge” of this walk welcome birders of any level of expertise.  The only requirement is that you enjoy the birds.

March 6 - Nisqually NWR


This morning was cloudy, for the first time in a while, but still cool at 32° with no frost.  I drove out to Nisqually NWR for the weekly bird walk.  FWS Volunteers Phil Kelley and Shep Thorp led the Wednesday gathering, and today about three dozen birders went out.  The big draw today was that a Barn Owl had been reported along the east boardwalk of the Twin Barns trail.  All we could see of her was the top of her head in a cavity in a maple tree, but that made ‘most everyone’s day.

Snow began to fall as we continued our walk, but that didn’t deter this crew of avid birders. . . especially when there are good birds to be seen.
Happy birders, because they're looking at . . .

The snow continued as we went out onto the Estuary Boardwalk.
But we were rewarded for our efforts by finding a nice male “Intergrade” Green-winged Teal.

Birders use the term intergrade to describe a cross between two subspecies of a species, whereas the term “hybrid” would refer to a cross between two different species.  This bird has the horizontal white stripe of the Eurasian Green-winged Teal, as well as the vertical shoulder stripe that distinguishes the American subspecies.

The snowfall abated as we returned from the estuary observation deck, and we enjoyed more mild conditions for the remainder of our birding to end the day with 68 species.  Not bad, given the weather and the visibility.

Hope to see you at the Nisqually Visitors’ Center one of these Wednesdays.  8 a.m., rain or shine - or snow!
