Island Update from Kay!

Posted by: nina-karnovsky | June 22, 2018 | No Comment |

The chicks are hatching!!!!!! We are doing feeding studies, and I am already attached to c chick, which I know is a dangerous game… yesterday we had a peregrine falcon that took two of our common terns 🙁 Also, Kay has caught and banded several puffins and she has named one “Prof. K.” I am so touched!

Sagehen on Southeast Farallon Island!

Posted by: nina-karnovsky | May 25, 2018 | No Comment |

Clare’19 who was on Seal Island as part of the Puffin Project last summer is now out on Southeast Farallon Island! She is continuing the tradition of Sagehens out on the rock. In past years Matt, Kristina and Eleanor contributed to the collection of the long term data sets that have become part of several senior theses. Clare says “I love it here- there are more birds than I’ve seen in my life! So far I’ve been doing work with Brandt’s cormorants, tufted puffins, elephant seals, rhinoceros auklets, and obviously Cassin’s auklets!” The Cassin’s auklets will be the subject of her senior thesis.

Planting Halos

Posted by: lars | November 8, 2017 | No Comment |

Once upon a time, during the spring bloom, you could have looked out onto the Channel Islands from the Southern California coast and seen one island with what would have appeared to be a bright yellow halo around it. That island, Anacapa, is angelic no more. But let me back up a little.

A few weeks ago, my Advanced Animal Ecology class, led by the inimitable Professor Karnovsky, took an overnight trip to Anacapa Island, the second smallest of the five Channel Islands off the coast of Southern California. This was no jet-setting island adventure, however. While on the island we volunteered with three Channel Island National Park biologists who work to study and conserve the island’s wildlife. It is one of these biologists who first told me of the island’s long since lost halo.

Our initial approach to Anacapa. If you squint your eyes you can just see the yellow ha… ah never mind.

It turns out that the island no longer look the way it did a couple of hundred years ago. The halo effect was the result of dense coverage by a large shrub called giant coreopsis that has lots of bright yellow flowers when it blooms. But when humans introduced sheep and later rabbits to the island, the giant coreopsis was devastated by the grazing of these introduced species. Today, many species of vegetation once common across the island have become rare, as the dominant plant has become red-flowered ice plant, an invasive species planted by the Coast Guard. These endemic (native) island species (plant and animal) are often particularly susceptible to being decimated by introduced species such as sheep and ice plant, as they have often evolved in an ecosystem without significant competition or predation.

The red-flowering ice plant, which was introduced to the island by the Coast Guard.

This vegetation has serious implications for the numerous organisms that depend upon the island. The protected area beneath the native shrubs that once dominated on the island offered quality nesting sites for sea birds such as the Scripps’ murrelet, which cannot nest under the low-lying ice plant. On Anacapa in particular, whose sea birds only just recently were able to recover following the removal of yet another human-introduced invasive species, the black rat, the mending of the island’s vegetation in favor of native shrubs is vital to bringing the island back to previous levels of viability for the numerous organisms that live on it. This is where Anacapa’s resident biologists and my class come into play.

Upon arriving at the island we met with the three resident biologists, Jim, Amelia, and David, who introduced us to the island and to one of their projects: restoring native plant species to the island. Using a small greenhouse as a nursery to grow seedlings of various native shrubs, the biologists then plant those growing shrubs in patches, so as to begin to the restoration of areas of native vegetation. This is precisely what my class and I did for our first afternoon on the island. As we planted we learned that the island’s native subspecies of deer mouse has been eating many of the shrubs they have been planted, due in part to a mouse population boom resulting from good rainfall in the last year. While I am not particularly fond of mice, being slightly phobic towards anything with buckteeth, hantavirus, and a tail, these mice are native to the island, and we hope that with more and more vegetation restoration, they will become a less prominent issue.

We managed to put in around 350 individual plants.

Me, smiling (?) through the grime of our planting efforts.

After a much needed hop into the ocean for some snorkeling, we cooked dinner with Jim and Amelia (David rotated back to the mainland) and got some much-needed sleep. The next morning we met up again with Jim and Amelia and spent several hours working in the nursery, helping to transfer growing seedlings into individual nursery pots in which they could continue to grow before being planted. After lunch and another swim, we toured the lighthouse and lined back up for our ride home. Bouncing over the waves on our way back to Ventura Harbor, I think we all felt much increased appreciation for three things. First, the biologists who spend their lives working to maintain and restore the health of the Channel Islands ecosystems. Second, the importance of being ever vigilant in the maintenance of those fragile ecosystems and the devastating impacts of introduced species. And third, the extraordinary amount that some unskilled volunteers can accomplish to help both those biologists and the islands they tend to.

Clockwise from top left: Katie, me, Clark, Jack, and Prof K. We were able to swim and snorkel in the water of the boat dock. They were all very jealous of my wetsuit.

Update from Sagehen on Seal Island

Posted by: nina-karnovsky | August 8, 2017 | No Comment |

Mid-July update from Clare!

Everything’s still going great here! Almost all of the chicks on the island are hatched, so we’ve been super busy with feeding studies. I think my favorite thing we do out here is tern feeding studies, where we sit and watch 6 nests for three hours and mark down when parents bring in food and what they bring in. I love just getting to observe their behavior, and you get to know the birds in the feeding studies really well. Our tern chicks are fledging right now, so it’s getting pretty crazy in the colony with all these new fliers!

UPDATE FROM SAGEHEN STUDYING PUFFINS ON SEAL ISLAND!

Posted by: nina-karnovsky | June 26, 2017 | No Comment |

Clare received a Summer Undergraduate Research Grant to carry out seabird research this summer and sent in this update:

Right now I’m with the Audubon’s Project Puffin out on Seal Island, Maine, which is 25 miles off of the coast.  There are only 6 of us sharing our 65 acre island, which contains a cabin with a stove and a table and 6 tent platforms. We each have our own tent, and hang out there or around the cabin area during our downtime.

SEAL ISLAND, my tent does not have a tarp in this picture but it has one now.

While our main focus is helping restore puffins to Maine, we also work with all of the island seabirds- puffins, razorbills, common and arctic terns, guillemots, murres, and double crested and great cormorants.

A PUFFIN CHICK is the softest thing I’ve ever felt.

An average day starts with waking up at 5:45 to do the morning bird count at 6.  We then eat breakfast and have some coffee, and start working again at 8.  We’ll often do a blind stint in the morning, where we sit in a blind for three hours and try to read the bands on terns and puffins or conduct feeding studies where we keep track of what fish they’re feeding their chicks.  We’ll then break for lunch and leave the birds alone for the hottest part of the day, then start back up again around 2:30. We also do a lot of puffin and razorbill productivity checks, where we go around to their burrows in rock crevices and check to see if they’ve laid an egg, or if an egg has hatched.  We all take turns making dinner, then hang around in the cabin for a little bit chatting, before an early bed time of around 8:30.

MEASURING AN ARCTIC TERN

Seal Island is absolutely beautiful, and I feel so lucky to get to work with such incredible birds every day!
