Sea star wasting: A recovery?

SeaStar3 SeaStars1 SeaStars2I never thought I’d be thrilled to see a few sea stars (starfish). But after nearly two years of bad news regarding sea star wasting syndrome (they literally melt into oblivion), there’s some good news.

First, scientists know the cause — it’s a virus. Knowing the source is a great start! But it’s a virus that’s been around for a while and has never before wreaked such havoc — killing sea stars all along the North American west coast. So, there are still a lot of questions that need answering: Why so deadly now? Are there contributing factors? How has this changed the shoreline community (sea stars are major predators)? Will the virus strike again in the same way, and if so, when?

The other good news is our sea stars are coming back. Along the Monterey Coast Guard Breakwater today, I saw at least a dozen individuals feeding on the mats of mussels that have thrived since the local stars disappeared. I’m so thrilled to see them back.


Surprising structural color

Mallard1I love when I download a set of shots from camera to computer and find surprises — pictures I didn’t know I had. It’s what keeps me going as I delete hundreds of bad shots.

This set of three shots is a perfect example.


Mallard2Just to practice I photographed this male mallard as he walked by me up the beach toward the sun. Mallard shots are easy to get so I wasn’t expecting anything special. To my surprise and delight, I got a stunning example of the structural color of feathers.


Mallard3There’s no true color here. It’s the structure and layout of the feathers and their reflection of light that create what looks like three different bird heads. But this is the same bird all within a minute’s stroll. No photo or color adjustments on my part.

Nature is amazing!

Breakwater blues

Cormorants Now is the time of year that I start visiting the Coast Guard breakwater in Monterey Harbor to watch the sea lions and cormorants battle for dominance of the rocks. The Brandt’s cormorants typically win and nest on the breakwater until their young fledge in the summer. It’s always been a great urban spot for wildlife watching. NewBreakwaterFenceUnfortunately, I won’t be seeing much this year because a new fence has been installed (it’s in addition to the old one), and there’s no longer access to the premier wildlife viewing end of the breakwater. I don’t know if the fence is temporary or permanent. It may be related to repair work the Coast Guard wants to do to the dock. Or, the fishing that occurs close to that end. Maybe it’s due to harassment of the wildlife. It would be a shame if the carelessness of a few people has ruined respectful enjoyment by the rest of us. I need to ask around about this new addition. (Update: I learned from the Coast Guard that the fence is permanent and is to keep anglers from fishing too close to the birds and sea lions.)

CormorantSo for now, no one can see what’s happening on the breakwater rocks unless they’re in a boat. Since this discovery, I have the blues, and I’m sure visitors and anglers who frequent the breakwater do too. It’s so sad to lose such a great spot for watching the annual cycle of life.

Dead on a beach

RainI haven’t posted much lately, and I’m going to blame the sunshine. This is the first rainstorm that we’ve had this year, and only the second of our winter rainy season. It’s just been too nice outside to sit inside and write. So here I am today.

Given the gray and gloom, I thought I’d write about why I like walking Del Monte Beach so much. It’s considered by some to be the “trash” beach of the Monterey Peninsula. Maybe it’s the currents or the harbor breakwater, but it seems that most of what dies at this end of Monterey Bay ends up on Del Monte Beach. That, for me, is what makes it so interesting. I love being witness to the cycle of life and getting a glimpse, sometimes an unpleasant one, of what’s happening in the bay and along the coast.

VultureFlying by CMaParsonsCaution: This post contains pictures of dead and decaying animals. If that sort of thing bothers you, you might want to move to a more lively post.

A signal that there’s something interesting on the beach are the turkey vultures (Cathartes aura). I grew up calling them buzzards and have always been fascinated. Sometimes I see them overhead, but I usually find them working on whatever has landed on the sand. Even though I’m walking only a few hundred yards from a major road, the sight of them always transports me to another age when large vultures were as common on beaches as joggers and dog walkers today.

Turkey vultures don’t seem fussy about what they eat. I’ve seen them eating mammals, birds and fish. I commonly spy them dining on dead sea lions. Vulture&Guts by CMaParsonsIf you stand still, you can watch them for quite some time (if no one else scares them off). This winter is shaping up to be like those of the last two years with weak, hungry and sickly young sea lions stranding themselves on beaches. Right now Southern California is getting more of them than we are. Experts believe the young sea lions are not finding enough food, but aren’t sure why. Warmer water conditions (possibly related to climate change) are often blamed. NOAA (National Oceanic and Atmospheric Administration) sometimes declares a mass die off as a Unusual Mortality Event (UME), as was done in 2013, which scientists investigated. The cause of that event is still undetermined, according to the NOAA website. I’ve found no UME declared for this year’s sea lion strandings — maybe the rescues are high and deaths are low.

Cassin's Auklet2 by CMaParsonsThere’s definitely a UME happening this winter. Thousands of young Cassin’s auklets (Ptychoramphus aleuticus) have washed onto beaches from Canada to Southern California. On one short beach walk I counted 50 dead birds. This is very unusual. These are seabirds that I’ve seen on whale-watching trips, not on beach walks.

Necropsies have shown that the birds are starving — not enough zooplankton (tiny drifting animals) to eat. Again, no one’s exactly sure why. This past year we’ve had little upwelling (shifting currents allowing deep, nutrient-rich water to come to the surface). Without the nutritious water, there’s less zooplankton, and so less food for auklets. It’s sad to see so many emaciated feathered bodies with blue feet littering the beach.

Mola on Beach by CMaParsonsA common sight every year, usually in the fall, are dead ocean sunfish (Mola mola). These fish are without fins and eyes. They’ve been victims of a tough frisbee game — a sea lion grabs a fin and throws the sunfish to tear it off (presumably to eat). Without fins, the fish are unable to swim, get caught in currents and tossed onto the beach. Gull&Mola by CMaParsonsGulls are responsible for removing the eyes. The beached sunfish are always young and about the size of a hubcap. The adults are much larger and likely too big or too tough for sea lions. In January I saw more sunfish than usual, and that also may be attributed to the winter’s warmer water.

Sheep Crab by CMaParsonsDead crabs and crab carapaces (shells) are very common, especially during the summer. To grow, crabs molt (shed the old shell) and this litter traces the tideline. Most of the crabs are less than an inch (2.5 cm) in size. This sheep crab (Loxorhynchus grandis) was the exception at nearly a foot (30 cm) across. This was a rare sighting — I’ve only seen one like this so far. I was sure it was dead, but too chicken to test if it was the whole crab or only the carapace encrusted with barnacles.

Thresher Shark by CMaParsonsThis last animal was a very unusual sighting — a thresher shark on my beach. I couldn’t believe it. The gulls and vultures were enthusiastic, too. I’m not sure of the species: a common thresher or pelagic thresher (Alopias sp.). The fish was intact and had no bite marks or other open wounds on it, but it was, as you can see, bruised and bloody. If I were to guess at the cause of death, I’d say that it was caught, and died in the net or after it was released. I don’t know what else would cause those bruises. It’s a beautiful animal (as are all of these, especially when alive in the water). I’m sad they died, but glad they ended up on my beach, making my walks more interesting and enlightening me to what lives in the bay, while worrying me about how our ocean is changing.
