Owls, 'spurs, Lichens, and a Birthday

7-9 October

This period brought us more uncooperative weather for large movements of landbirds, but we did get a slow trickle of fun new avian visitors. These included an adult Blue-footed Booby, our first Herring and Thayer's Gulls of the season, a Pectoral Sandpiper in the Zalophus wastelands, a Western Palm Warbler (a harbinger of the hordes), a Lapland Longspur, and a White-throated Sparrow. These were in addition to small numbers of more expected birds.

eBird checklists for 7, 8, 9 October.

Burrowing Owls have been increasing, as is typical in the Fall. They arrive during peak mouse density, stay until the mouse population crashes, then switch over to eating Ashy Storm-Petrels: one sensitive species eating another--not an ideal situation. A recent arrival was "Tenacious D-15" below. This owl was banded last year and has returned to the same hole. It likes its hole and won't readily leave it. Witness:
"I don't care how big you are."
"Come on in. The kettle's hot."
This Lapland Longspur would briefly visit a disgusting puddle near the lighthouse, then disappear for minutes to hours. Not everyone was able to see it during its 2-day stay.
This lichen (lichens?), as far as I can tell, is limited to the metal railing around the lighthouse. What does this mean?

Ron Elliot has also returned to dive around the island, as he has every year since the 1980s. He's the only regular visitor (pretty much the only visitor, period) to dive without a shark cage. Watch this excellent video about Ron, featuring footage from the islands--it's worth your time.

Jacob "I Know John Garrett" Drucker recently had a birthday. Don Mastwell made him some kind of chocolate corn cake. It was structurally disingenuous.

What's Better Than Two? Ten.

30 September to 4 Oct 2016

Deepest apologies to all of the portrait fans who have been waiting far too long for the next installment. As a result of communication breakdowns, plumose foreign-body aspiration, and a few days with Loads of Birds, I have fallen behind. Fear not, portrait enthusiasts, for ten is five times better than two.


Regarding aspirations, I inhaled a belly feather from an Audubon's Warbler on 2 October. This is not advised. Inhaling anything but nicely oxygenated air is a bad idea. I asked Peter Pyle if he'd ever inhaled feathers. He said no, but told me about a researcher extraordinaire  (below) who may have died from long-term feather exposure. Thanks, Peter!

Here's hoping that we have many more days of TPAD ahead of us. If not, it's been fun. I love you all!

This Lesser Goldfinch acquired a bad pollen habit during its stay on the island.

This Northern Fur Seal is upset about something.

We finally caught the Black-throated Sparrow!
The orange character is Edrudia constipans, a lichen found only on the Farallones 
This Pacific Wren spent most if its stay in the cable tunnel beneath the lighthouse. Here it pauses for some brief sunshine.

Great White! This fellow had just finished eating a pinniped--probably a sea lion, but impossible to know for certain

This Sharp-shinned Hawk flew about at the lighthouse for a bit before heading back to land.
