The Snail Pace

Life is precarious in tide pools. Mussels and barnacles that live too low on the rock surface are within reach of predatory starfish. Those too high are at risk of drying out while they wait for the rising tide. And in this case, the high spots also had just enough purchase for a black oystercatcher to walk along their perimeter, feeding as it went. But its target on this day was not the mussels and barnacles but the snails that feed on the algae on their shells, here it is about to swallow the soft part of a snail it has extracted from its shell.

The oppressive summer heat might be the biggest obstacle I had to overcome to be willing to move to the desert, but not far behind was saying goodbye to the coast (and in California, the nearby wetlands). I was rather taken with tide pools and the coast in general on visits to the redwoods in California and the rain forests in Washington and decided to make a concerted effort to visit the coast more often, which is why I was at the Oregon coast on this day in early October. A few weeks later I’d find out my team was getting laid off and thus started the process that would take me from the Northwest.

I changed the lock screen on my phone to this picture of a harbor seal as soon as moving to Arizona became a possibility, before it even became a strong possibility, to force myself to think repeatedly about whether I could really give up the coast. I decided I wasn’t ready to say goodbye to the coast, and never would be, but I was ready to say hello to the desert. And to the desert I go.

The Oystercatcher

A black oystercatcher stands in what must feel like heaven to a bird that eats mollusks, a rock covered in goose barnacles and California mussels. When the tide comes in this rock will be underwater, something I still have trouble wrapping my head around. I love watching and listening to oystercatchers as they hunt in the tide pools so it was a special treat to get to photograph this one so completely in its element. After watching them at several places in California and Washington, I began to wonder why some of them had extra black spots next to the pupil of their wondrous orange-ringed yellow eyes, leading me to a paper that suggests you can fairly reliably determine whether the oystercatcher is male or female by these eye flecks. I suspect this one may be a male since it had only small specks next to its pupil, they were hard to see unless I zoomed in on the picture.
