Well I led the group on a plant walk today. This helped me learn alot about both the native and introduced plants on the islands. Did you know there are now more species of introduced plants on these islands than native plants? Some like guava and quinine have almost completely replaced the native plant communities on some of the inhabited islands.
I was doing a final walk through getting ready for the walk this afternoon, and while I was sitting and looking over my notes, I looked down and there were 6 to 8 ground finches right by my feet. They are every where and very tame. The other afternoon when I was in the internet cafe I looked down and there was a male yellow warbler right by my foot pecking at crumbs on the floor. He was just a couple inches from my foot.
Tomorrow we go to help remove black berry from the El Junco area in the highlands. Sunday is a free day, maybe more snorkeling with the sea lions?
Tuesday we leave San Cristobal for Isabela, Floriana, and Espanola.

tide pools with kids
Whew! What grand madness! We took about 60 kids ages 8 to 10 or so to the tidepools today. These kids are in a Navy School, and if it was in the US you would expect some regimentation. Maybe the kids would line up and march to the tide pools at least? Nope. It was more like herding cats, 60 of them down a road next to a quarry and then to the beach. Were they excited! We found an octopus, brittle stars, sea slugs and sea hares, and very frightened fish. The sea lions however were unfazed by the frenzy of small mammals running and jumping over rocks and into the tidepools.
I think we got all the kids back to the school. We were going to count them as we started back, but one of the teachers just started walking so they followed...
I did notice that none of their teachers came out into the tidepools with us. Instead they sat on the beach and chatted.
As far as my mockingbird research goes, I haven´t seen any in the natural area where I have been looking. Tomorrow I am going out at 6 AM to see if I have better luck in the morning. The weather reamins pleasant, and the sunsets fantastic. I am glad I have the wetsuiit. When we did our water testing we discovered the water is no warmer than 63 degrees. Brrrr

geckos and w a ter quality
Hi,
This morning was another water quality day and last night was gecko hunting. I had a group of four girls with me as we searched the walls and fences of houses near the ocean for geckos. There are at least two introduced species here and one native. We found one gecko, and had a friendly dog following us around for awhile.
This morning we were out in the bay again testing water. We had planned for two boats of kids, but yesterday were asked to make changes to handle three boat loads. I got o n the first skiff this morning,and that turned out to be the only boat that showed up to take students. So f rom three to one. We also got some plankton samples we will look at tomorrow in lab. I have not seen any Chatham mockingbirds. My project is to census the San Cristobal mockingbirds and I will start th atlater today.Since one of the the ohter students and i set up the whole water quality testing procedure we are getting a break f rom counting lava lizards today.

lizard hunting
Today was a day of water testing in the ocean on a little navy skiff and walking across town to count lava lizards. My team had a rather natural area so we found over 40 lizards. I think the students in the class I am in are much more interested in the project than the kids at the navy school however. Kids in my group ducked into shops to buy drinks as we walked around,and collapsed in "exhaustion" on the sidewalk at one point. I am hoping the nightime gecko hunts around the neighborhoods go better.

School kids tomorrow
Hi All
Today we went and saw where the galapagos tortoises are being hatched and raised in a safe environment until they are old enough that they will not be preyed upon by the feral cats and rats on the island. We also walked to the top of a collapsed caldera called El Junco. Friget birds come and dip their heads in the fresh water lake that has collected in the caldera. This is the only fresh water on the island and is also the source of drinking water for the people on the island.
Tomorrow I start with the local kids. My team is taking on water quality testing in the harbor here. It turns out there is a sewer outfall of untreated sewage into the harbor not far from where we all went snorkeling the first day. Ewwww.
The weather continues to be great.

Snorkeling with the sharks !
This morning we went out to kicker rock off the coast of San Cristobal to snorkle. We swam through a narrow channel between two pieces of the rock and swarming below us were galapagos sharks! There were multitudes of beautiful fish and we also saw a turtle in the water. On the rock face were bright orange sponges along with anenomes and swarms of fish. Afterwards we went to a beautiful white sand beach to warm up as those of us without the natural insulation I have were cold even with their wetsuits. Next was Lobo Island. Lobo as in sea lions. They were jumping out of the water as we arrived and surrounded us once in the water. I hope I got some good pictures of them. I shot a whole roll of film in the water while playing with the pups and their mothers.
Yesterdays hike was quite challenging as it was over lava rocks, but worth the effort as we saw red billed tropic birds and blue footed boobies and swallow tailed gulls. The walking stick I brought was extreamly helpful as I hopped from rock to rock. On the way back I fell and heard a loud crack. My walking stick snapped in half, but at least it wasn´t my leg....
lTomorrow we head for the highlands on a hike. I am feeling great and was just thinking today this town would be a great place to live.

San Cristobal
Hello All,
Was it yesterday or the day before I went snorkeling with sea lions? A female came right up to my face mask and blew bubbles at me and then swam off into the green of the ocean. I also saw a sea turtle, and urchins,fish and more beautiful fish ! Tomorow we are going snorkeling again at Kicker Rock where we may be able to see sharks! Later today is a hike where we should be able to see swallow tailed gulls, tropic birds, and more blue footed boobies.
Sea lions sleep steps from our hostel (which does have hot water in the showers at 6 AM and then around 530 PM) Next week is working with school kids in the AM and our research projects in the afternoon. The Chatham mockingbird remains elusive, although there is one I am keeping my eye on.
It has been beautiful here the ocean is a rich blue or green with great visibility. I´m having a great time.

Santa Cruz Island
What is it about 2 AM arrivals. First tanzania now Ecuador. No matter,I am here! We are in Santa Cruz and leaving this morning for San Cristobal. We have been to the darwin research station, and wandered around town, had great food, and seen amazing animals. So far the lava gull has been around the harbor, herons, pelicans, and two species of darwins finches! Marine iguanas, and beautiful sally light foot crabs on the rocks in the harbor! It was a beautiful morning today. We got up at 6 to walk and bird and photograph. The light was amazing. As we arrived via a short ferry ride to Santa Cruz we were greeted by hundreds of blue footed boobies diving for sardines in the bay. Hundreds at a time plunging into the water was a spectacular site!
Adios!

Galapagos Islands
Hi Folks,
Up to now this blog has mainly been used for my Bio 120 class, Intro to Biology. However, now that I am on my sabbatical, I'm going to be posting from areas around the world where I am traveling. First is the Galapagos. On July 7 I leave for San Cristobal Island, then on to others in the chain. Take a look at my links for a couple of Galapagos related links. There are internet cafes in
Puerto Baquerizo Moreno, the town where I will be for the first two weeks. I also hope to be able to upload a few photos at least while I am there.

Shipley Nature Center
Hello Biology Students,
This morning I spent several hours volunteering at the Shipley Nature Center in Huntington Beach shoveling compost. First we shoveled newly composted mulch out of compost bins, then shoveled material to be composted into the now empty bins. Afterwards I wandered around and took a few photos of the plants in bloom I thought you might enjoy. I altered them a bit in photoshop.
