Ready to explain my project!

Ready to explain my project!

So starts my 6th week working on my programming project. I’m currently working on putting my programs together so that whole files of data can be analyzed automatically when imputed into the interface I’ll be designing later this summer. The challenge is finding patterns in the file that allow the program to understand when a set of data is starting and ending so that it can be analyzed but the correct other program.
Last week I took a break from programming to create and present a poster on my project at a HHMI conference at Harvey Mudd. It was great to see what other people around me are working on and to meet some of the other people on campus as well as see enthusiasm for my project!

Python in the lab!

Posted by: nicole | July 14, 2014 | 7 Comments |

Hi all!  I’m Nicole, a rising Pomona fourth year, and this summer I’m working with data on the diving patterns of Cassin’s auklets in the family Alcidae.  These sea faring birds budget their energy and time depending on prey availability, and the feeding needs of themselves and their chicks.  Auklets also demonstrate different types of dives: more ‘V’ shaped dives tend to be for finding pockets of prey underwater, while more ‘U’ shaped dives are more for actual feeding.  These data were taken by gluing small Time-Depth Recorders (TDR’s) on the body feathers of individual auklets and recording temperature and pressure on preset intervals as the birds go about their daily routines.

Here's me in the lab!

Here’s me in the lab!

Other projects have looked at different aspects of these data and my job is to process the most recent years.  Three weeks into my ten week project, I’ve so far been writing python programs that will take a file of data from an individual bird and separate the data points into dive bouts made up of dives as well as calculating different attributes.  One of these attributes is how U-shaped a dive is, which I calculated by determining what percentage of the data points are in the lowest 25% of the dive depth. Over the next few weeks I’ll be developing an interface for these programs and can then decide what aspect of these birds’ behavior I’m most interested in analyzing for my thesis!

How to PIGU

Posted by: jamie | July 14, 2014 | No Comment |

Pigeon guillemots (PIGUs) are unquestionably the most adorable of all the birds we study here at Sea Ranch. And until recently, we didn’t get to spend that much time observing them. But for the past couple of weeks we’ve been doing three hour nest surveys every other day, getting an idea of how often adults bring food back for their chicks, and what exactly they’re bringing. To introduce you to these adorable birds, I’ve drawn a comic. This is how a typical feeding event goes:

Okay, so they don’t actually hit the rocks around the nest, but they do often miss completely. We had one bird do this five time before successfully entering the nest to feed it’s chicks. Pretty amusing to watch! The birds are mostly bringing back sculpins, with the occasional larger, silvery fish (possibly sand lance?) and even one squid/octopus (it was pretty droopy and hard to identify). We’re watching two nests and so far only one is bringing food back. We can’t see into the nests, but we’re guessing, based on the comings and goings of the adults, that there might be eggs in the as-of-yet-unfed nest. So perhaps we will have more bird antics to update you with soon.

In other news, one of our pelagic cormorant nests fledged today! Two chicks were still in the nest, but the other two were swimming around in the water below, and occasionally taking brief test flights. The babies are growing up!

Quick update from Sea Ranch

Posted by: jamie | July 12, 2014 | 2 Comments |

Hi folks,

It’s now Jamie and Sophie here in Sea Ranch. A few days ago, an osprey that had recently caught a fish landed near our observation point, and we managed to get a mediocre phone video through our scope. Check it out!

 

Other than that, the birds are doing well (and the chicks are getting huge!)

Check back in tomorrow for an illustrated update about some new data we’re collecting. It’s adorable, we promise.

Eleanor’11 who might remember from her 2009 posts from the Farallones Islands where she collected data for her senior thesis, is currently working on her PhD at Duke University. She writes, “I’m focusing in on a PhD topic regarding convergent evolution in signaling and phenotypes in cleaner shrimp.  I’m interested in why cleaner shrimp have such crazy colorful phenotypes, and whether it acts as a signal to client fish or to each other, or perhaps as camouflage against certain backgrounds, or maybe both!”

“Sea” You Later, Sea Ranch

Posted by: ramon15 | July 7, 2014 | 3 Comments |

On the morning of July 5th I departed Sea Ranch and made my 9-hour drive back to sunny SoCal. But before that, I needed to take care of a few things:

1. Pack. I still needed to pack that morning, which was not too hectic. Before leaving, I grabbed Jamie’s book, which I’ve started reading during one of the foggy GPI surveys. It was Ruth Ozeki’s A Tale for the Time Being and the story is partially set in an isolated island off the coast of British Columbia. In this haven for nature lovers, where the days and nights are kissed by wind and fog, the denizens’ daily conversations center on barnacles, crows, and the Great Pacific garbage patch; for me, reading about these people’s daily activities was like reading about the lives of the Sea Ranch residents. Thank you Jamie for lending me this book, and I promise to ship it back to you on the back of a whale.

2. Say goodbye to the Hichwas. As I entered the house, I was greeted by their dog, Bridget, amiable as always. I patted her on the head and looked for her owners. When I found them, we shared some parting words, and then I returned a Nat Geo magazine that they had lent me, since it featured an article on my favorite type of plant: mangroves. They told me to keep it, which was a great example of their generosity over the 5 weeks that I stayed in Sea Ranch. They’ve shared with me their warm abode, equally warm meals, and a wide range knowledge and experiences, which spanned Pigeon Guillemots, the workings of a camera, weird cuisines in Japan, and words to finish the daily crosswords from The Press Democrat that I worked on after my GPI mornings. Thank you Diane, Bryant, and also to Jim Weigand; the three of you have greatly enriched my Sea Ranch experience. With your help and patience, I’ve grown from a confused intern who didn’t even know the term “bluff” to a fledging birder.

3. Visit Gualala for the last time. After getting gas for my long trip and cleaning my windshield from all the dust its accumulated by sitting under the shade of the gorgeous redwood trees, I visited the weekly Farmer’s Market. Since every morning, I had a date with the birds of GPI, I never had the chance to check it out and visit the used book sales that they had. For $1.50, I got Gabriel García Márquez’s One Hundred Years of Solitude. After the transaction, the bookstore volunteer gave me a genuine smile and a “take care,” which reminded me of the great kindness and friendliness of the residents of the Sea Ranch and Gualala. In my stay there, I’ve met an array of kindhearted and fascinating people who have not only been a great help in my project, but have also made me feel a part of their community.

4. Drive down the highway strip for the last time this summer. I want to emphasize this summer, because this is surely not my only visit here. I did not directly say any goodbyes to anyone, but only “see you later”s. As I drove the Sea Ranch strip of Highway 1 for the last time during my stay, I paid good attention to the stunning sights that had become ordinary to me. I noticed how, as always, the fog enveloped and hugged the coastline, and I took that as Sea Ranch giving me hug, bidding me with a, “See you later.”

-Ramon

P.S. And now, more non-chick pictures that I’ve accumulated during my stay:

The Gualala River, which travels along the San Andreas Fault.

Another gorgeous view of the Sea Ranch, with fog in the backdrop, as always.

Gualala Arts brought in Yakut sculptors from Siberia to build an art piece at the Regional Park, in celebration of their Sakha Cultural Festival.

The beautiful final product.

Jamie’s Grand Arrival

Posted by: ramon15 | June 29, 2014 | No Comment |

Saturday evening. It’s almost 9 pm and the sun has just set during a crisp summer night here in the Sea Ranch. I have only a week left and my replacement came two nights ago. The substitute: no other than the acclaimed seabird expert and recent Pomona graduate, Jamie . Even though he’s only been a Sea-Rancher for two days, he’s already an expert at spotting all the mobile gull chicks and is on a first-name basis with our beloved PECOs.

Jamie takes photos of the PECO chicks at Breaker Reach.

He’s also checked out prime spots for some possible free diving and surfing, and has even purchased a fishing license and a spear with which to get his next dinner.

With a wide grin, Jamie shows of his new spear and fishing license.

We’ve also moved into a new house, thanks to some very generous local residents. It’s up in the redwoods and will be our abode for the next week, until I leave for home and Jamie takes over for the next month.

Our new housing arrangement, beautifully surrounded by picturesque redwood trees.

And, as an added bonus, here are some more GPI-seabird photos, professionally taken from my iPhone through a scope. Enjoy, and till then! -Ramon

Brandt’s Cormorants and Common Murres share this spot of Gualala Point Island and “mingle” with one another.

Adult Western Gulls watch over their cryptically-colored young. How many chicks can you spot?

A sight not too often witnessed, we saw several Heerman’s Gulls make a pitstop on the island.

And of course, fog to limit visibility.

My Morning Routine: GPI

Posted by: ramon15 | June 23, 2014 | 1 Comment |

“So Ramon, what DO you actually do over there at Sea Ranch?”

This might be a question that readers have for me, given that I’ve never fully outlined what my day looks like here. And since I’ve talked about the PECOs that I survey every other afternoon, it’s time to talk about what my mornings are all about: Gualala Point Island.

This small island, only a couple hundred feet from shore, is a different world on its own. Geologically speaking, GPI is complex, which makes it a favorable habitat for nesting seabirds; Pigeon Guillemots enter crevices between rock layers, Pelagic Cormorants nest on the rock ledges, Brandt’s Cormorants settle on the limestone flats of the island, and Western Gulls occupy the flat areas at the top of the island.

My job is to keep track of all these nests, as well as all the visible species that are present on the island. From each of two vantage points (north and south), I do a count of all the seabirds and mammals present on the island. I also monitor the status of all visible nests, using a photo that shows the location of all the tracked nests (which are given a unique number). Additionally, now that most of the gull chicks have hatched, I also keep track of these mobile (emphasis on the word mobile) chicks that run around the vicinity of their original nest site.

A view of GPI from from the south side, as well as the back of Sophie’s head.

Tallying all the seabirds that I see.

Sophie counts all the brown pelicans the fly by the island. At one point, we saw more than a hundred!

With this information, I can further understand habitat use in the island. And, with data from previous years and from other nesting sites, I can also determine population and behavior trends of these species over time.

Unfortunately, not every morning here on the coast offers bright and calm conditions. We frequently get winds and fog that swoop into the coast, preventing us from clearly seeing the island.

Sophie and I get our breaks when the wall of fog descends upon us. Sophie spends her time reading, while I take selfies (for the blog, of course).

But overall, the process has become second nature, and I’m just about ready to name the hundred or so gull chicks that I keep track of, starting with the chicks from nest #47.
