A couple of quick photos of Elegant Terns (Thalasseus elegans) at Porto Bodega today (28 September 2026). There was quite a bit of feeding activity over the water, and then the terns came in to roost near the outer docks. Excellent views of these beautiful terns!

Intertidal habitat
Happy Fall!
We're still catching up after returning from Iceland, so I haven't taken new photos in California yet. But we've been talking about our Iceland tidepooling experiences and folks have had questions about what it was like. So here are a few habitat photos from various intertidal sites in Iceland:

Kentish?
Driving towards Búðardalur
Many scenes in Iceland triggered memories of Rockwell Kent paintings for me. I guess that's not really surprising, since Greenland is only ~186 miles (300 km) from Iceland. (Occasionally polar bears make the crossing on icebergs!)
A couple of views from the West Fjords:

Thunderous
We're back from Iceland but there were so many beautiful landscapes that I hope you don't mind if I share some more photos.
This is Dynjandi (and friends) -- a significant waterfall in the West Fjords. The trail passes a series of smaller waterfalls leading up to the largest cascade at the top. I was so entranced that I might have missed one, but this is the basic sequence from bottom to top. [You can click on the photos for larger versions.]

Drifting north
While walking a beach near the Garðskagi lighthouses (near the village of Garður on the Reykjanes Peninsula), I looked down to see a cluster of Blue Buoy Barnacles (Dosima fascicularis) in the wrack line.
Although we knew there were previous records of this species in Iceland, it felt a little surprising to see them. Most of the records for this pelagic barnacle are from further south. In California, we found these barnacles in Sonoma County during the warm-water events in 2014-2016 (e.g., see "Blue buoys!" on 31 August 2014).
Here's a close-up where you can see the thin, transparent plates. You can also see the white foam-like float that the barnacles make to stay afloat at the surface of the ocean (upper left corner of the image).

sandlóa, lóuþræll, and lóa
A few shorebird photos from Iceland. Above, sandlóa (in Icelandic) or Common Ringed Plovers (Charadrius hiaticula). (I really enjoyed hearing their calls.)
Next, a juvenile lóuþræll or Dunlin (Calidris alpina):

Tidepooling at 66° North
During our first few days in Iceland, we were fortunate to find some excellent tidepooling locations. We've been taking lots of photographs, but it's hard to find time at the end of the day to write a complete post , so I'm sharing a few fun highlights for now.

Blue-rayed
A beautiful limpet…from Iceland! Meet the Blue-rayed Limpet (Patella pellucida). We’ve done some tidepooling around Reykjavik during the last couple of days and this is a species I hoped to see. Lots of other amazing marine invertebrates to share, so stay tuned!

Butterfl-eyes?
Close-up of the large eye spots on the forewing of a Common Wood-Nymph butterfly (Cercyonis pegala).
Here's the entire butterfly, perched among grasses:
