Monthly Bird Survey at Shollenberger: October 2020

by Nov 2, 2020Bird Survey, Miles & Teresa Tuffli, News

Thursday, October 29, was the bimonthly bird survey at Shollenberger Park. The group gathered early, and the soft pink sunrise did not disappoint!

As with all survey mornings, a bevy of Red-winged Blackbirds declared “Good morning!” from the tules. As the sun rose, hundreds emerged en masse – here’s what it’s like to be beneath one of the emerging flocks.

And here’s a view of an extra large flock dispersing to the northwest.

Small flocks of Canada Geese streamed overhead as well.

Setting off for the count

The harsh cries of a hidden Red-shouldered Hawk rang out as we walked by.

We spied five tucked-in swans in the central pond which we assumed were of the Mute variety. But, when they later untucked, we discovered three Tundra Swans sitting beside two Mute Swans!

We heard a Northern Mockingbird singing and spotted it atop a tall tree, serenading the morning sun.

Near the Point Blue building, our count leader, Andy LaCasse, pulled the years-old remains of a barely recognizable kite from a tree. The White-tailed Kite was historically called the “Black-shouldered Kite” – you can see the remnants of the namesake black shoulder below.

As we came upon a group of foraging Killdeer, one took to flight and cruised overhead, giving us a look from below of its diagnostic double breast-bands.

Pop Quiz #2: Who’s the owner of this cute duck butt??? Stay tuned to find out.

In a small puddle beside the trail, we encountered a single Greater Yellowlegs rushing about.

This male Common Yellowthroat obligingly showed off his flashy colors to his eager onlookers.

As we watched a giant barge move by slowly in the Petaluma River, we heard a Virginia Rail call once from the tall, marshy grass.

Meanwhile, a Northern Harrier caught our eye as it effortlessly swooped past searching for its next meal.

Along the opposite riverbank, a healthy-looking coyote trotted by.


Though many folks tend to overlook and even scorn Rock Pigeons, we find their iridescence worthy of an admiring look.

Answer to Pop Quiz #1: The flying silhouette was a Black-necked Stilt.

By the end of the morning, the team had tallied 64 species for PWA’s October 2020 survey.

This has been your in-the-field recap of the PWA’s October bird survey. These are just one of the many ways the PWA fulfills its mission statement:

Dedicated to the stewardship, restoration, and expansion of wetlands and associated wildlife habitats.

We’re Teresa and Miles Tuffli of I’m Birding Right Now. Check back for future reports on these volunteer PWA bird surveys!
