Orcas!

What could be more fun than accompanying a 5-year-old on his first whale-watching trip?

Puget Sound off the coast of Washington is famous for its Orcas, or Killer Whales, and regular whale-watching daytrips run out of Port Townsend, on the tip of the Olympic Peninsula. We signed up for an excursion aboard the Puget Sound Express and set out on a sunny morning, destined for Friday Harbor on San Juan Island, and the waters between. Our luck was phenomenal.

A riptide raced between Lopez and San Juan islands, and no fewer than three (!) pods of the highly-social Orcas had gathered there to feed on salmon. Our boat drifted in the sea, as whales foraged, surfaced, and spy-hopped all around us. The boat's underwater microphone picked up the whales' vocalizations, and the captain broadcasted the evocative, eerie whale calls over the PA system.

Young Milo kept up a litany of "There's one! There's one! There's one! ...! There's a mommie and baby!" He also was first to spot one of the two Minke Whales which graced the morning. Minkes are the smallest of the filter-feeding baleen whales, while Orcas belong to a different lineage entirely: the toothed whales and dolphins.

We were seeing family pods of resident Orcas, those which stay in the coastal waters off the Pacific Northwest and which specialize in eating fish and some squid. Other types of Orcas include transients, which feed mainly on other marine mammals and travel in smaller pods, with weaker family bonds. A third type in the northeast Pacific Ocean is the offshore population, which feeds primarily on schooling fish far offshore. These three populations are genetically distinct and may even be separate species.


Orcas forage and spyhop around the boat.


Three types or populations have also been described for Antarctica, specializing on three foods: Minke Whales; seals; and Antarctic Cod. The genetic relationships between the various Killer Whale populations are still being worked out.

In addition to the whales, we enjoyed great encounters with Harbor Seals and Steller's Sea Lions. Seabirds were plentiful, especially cormorants, gulls, Common Murres and Rhinoceros Auklets, with a few Tufted Puffins and Red-necked Phalaropes added to the mix.

Skagit River Flats

After days of visiting family and painting a playroom to look like a ferny forest inhabited by dinosaurs, I step onto the night ferry from Port Townsend to Whidbey Island, Washington. The lights of town recede, and the dark waters and crisp night air of Puget Sound envelop the ferry.

My friend Jim Shiflett is waiting at the dock for the ferry's arrival.

Next day finds us in the flats of the Skagit River Valley and on Fir Island, which lies between the north and south forks of the river, bordering the estuary. Clouds hide, then reveal the sun. There's hardly a breath of wind. Western Washington is enjoying its warmest January on record.

We're in prime raptor habitat, although today the hawks and falcons are little in evidence. A rare dark-morph Rough-legged Hawk regards us. I'm struck again by how small its bill is, when compared to a Red-tailed Hawk's. A couple of Merlins dash past. Bald Eagles abound, numbering perhaps 40 or 50. Pairs perch near their huge stick nests, ready for the next nesting effort.

We find a big concentration of Snow Geese. Those that winter here in the Skagit Valley return each spring to breed on Wrangel Island, in the Arctic Ocean north of Russia. (Wrangel also has the world's highest density of Polar Bear dens, and Woolly Mammoths survived the longest on Wrangel, until about 1700 years ago!)

The Snow Geese share the Skagit Valley with literally thousands of wintering Trumpeter Swans. Many of the local farmers are paid to raise forage for the swans. However, we see two fields where swans and geese are discouraged in a novel way: the farmer has put out a Bald Eagle decoy in the center of each field, and the ruse appears effective. Neither of the fields holds a single other bird!

In the tidelands, masses of driftwood pile up, interspersed with swathes of grass. Short-eared Owls roost in these twisted roots and logs, emerging in late afternoon to hunt. One perches atop a small conifer growing amid the wrack––how beautiful these owls are!
