Chuck the harbor seal helps propose!
Not only is Chacoda a skilled voice artist, he's also pretty romantic! This week he teamed up with Lindsay to help this lovely young couple get engaged! Below are some screen shots of what happened. The Boston Globe has the full video here.

Calling all seal fans - Chacoda ringtone!
How would you like to hear a harbor seal say "hey! hey!" every time your phone rings? Well now you can. The Aquarium's youngest harbor seal, Chacoda, often makes gutteral noises. The trainers have been working with that behavior to see if Chacoda can learn to vocalize like his famous grandfather, Hoover.

Well, sounds like Chuck is getting pretty close to the sound of someone calling out "hey!" Click the play button to hear for yourself and use the links to download an MP3 for your phone.

St. Paul: Log #8 Old Tags, New Tags, and Tagging Along
New England Aquarium Senior Marine Mammal Trainer Patty is participating in the 2010 Northern Fur Seal Pup Count in St. Paul, Alaska. You can scroll through all of her posts from the field here.
Remember the challenge at the end of St. Paul: Log #7? Well, how many tags did you find? If you look closely, (and I realize it is a tiny picture on a computer screen) there are three. Here is the picture again with all of the tags circled. Now you can understand why we used binoculars and a scope! The animals are moving quite frequently and a tag can be visible one moment and gone the next so you really need to pay attention.
Females with tags circled in purple.

The researchers return to the rookeries at the end of breeding season, when the mothers and pups are getting ready to leave the island and migrate. They will remove the tags from the females and use all of the information gathered to help determine the relationship between a marine mammal who spends months on an island but must also travel miles at sea to find food all while raising a pup. Not an easy lifestyle I am sure.

After doing three days of re-sights, I was able to tag along (no pun intended) :) for the tagging of adult females at a site called Zap Reef. As one of the many research studies being done while we are out here on St. Paul, female fur seals on various rookeries are equipped with GPS tags which give scientists a lot of important information regarding where and for how long northern fur seals leave the rookeries to search for food in the ocean. Only females that have given birth to a pup this year will be selected to wear these tags. This ensures that they will be leaving and returning to the island frequently over the next few months as they feed their pups to get them big enough to leave the island on their own. These new moms will provide excellent information about how far out to sea they feed, how far down they dive to find food, and how many days they need to stay at sea to find enough food to return back to the rookery. The picture below shows what one of the GPS tags looks like.

There is still plenty more experiences that I can't wait to share with you so stay tuned!

St. Paul: Log #7 - Resights and Female Tags
Well, I have seen the last of my shearing days. Today the shearing team I am on is going to finish up at the last of our shearing sights and instead, I am going to learn how to do re-sights. Although the work has been exhausting, I am a little disappointed to miss out on the last day of our team's efforts. I think by day five I was actually able to hold my own and almost keep pace with the more experienced crew members (almost).
The one thing that I never mastered was picking up the pups in a way that prevented them from latching onto my gauntlets. Remember the picture of me in my lovely shearing outfit? Well the leather wrap that went from my wrist to my shoulder is called a gauntlet and it is meant to protect my arm should the pups bite. And they do. A LOT! This is what my arms looked like at the end of five days of shearing...painful! Crew members with more experience usually come away bruise free but that was definitely not the case for me. I'll have to work on that.

Before everyone parts ways, I asked everyone to gather up and take a picture in front of Staff Quarters. Here we are bright and cheery as always before we head out for the day.

And now I head off with Lou and Greg to learn about re-sighting. This is a very important study that has been going on for many years where female pups and adults have tags put on their flippers so that we can track their site fidelity (or likelihood to come back to their place of birth), mothering skills / successful birth rate and age survival.

It's amazing how much information you can get by knowing simply who the individual is based on when and where the tag was first attached. All of this research is done on St. Paul at a location called Polovina Cliffs. The cliffs allow us to observe the animals with minimal disturbance since we are so high above them. There are also blinds built on the cliffs to offer us protection in tough weather. It also gives us a great view of the activity below.
This project has been going on all summer, rain or shine. I had the opportunity to participate for three days and the weather can be daunting but you get caught up in the task at hand and start to forget that your fingers are no longer as mobile as they should be. For 6 to 8 hours the goal is to sight as many flipper tags as you can, note whether or not the female has a pup with her and what the female is or is not doing with that pup. It's kind of like playing a really intense version of Where's Waldo?.
Here, you give it a try. The picture below is a bull male with his harem. In it there is at least one female with a flipper tag. See if you can find any more. For re-sights we have binoculars and a scope but sometimes just using your eyes is the best way to catch a tag. Try it out and see how you do. I'll show you what I found in the next blog. Happy searching!
See how many flipper tags you can find!

This is also the last day that our whole crew will be together. Tomorrow, four of our crew members will be heading to St. George Island where they will start the shearing process on the rookeries there. St. George, seen in the figure below, has a smaller number of fur seals so approximately 1,800 pups will be sheared in order to get an estimate of the number of pups born this year.

St. Paul: Log #6 - Running with Scissors
Do you remember when you were little and your parents would tell you to never run with a sharp object in your hand? Well, that rule definitely does not apply during pup shearing on St. Paul! Out here you have a pair of sharp sheep shears strapped to your hip and when a group of pups are gathered together and the signal (it usually looks like that hand gesture from Neo in the Matrix... got the visual?) is given you move as fast as you can over wet, slippery rocks to get to them. The picture below gives you an idea of the topography that we deal with out on the rookeries.

The goal each day is to shear the selected number of pups as quickly and accurately as possible so that we can remove ourselves from the rookery and allow the bull males and their harems to come back up to their territory. So in this situation, running with scissors is recommended (safely, of course). Let me tell you, never before have I felt so uncoordinated! As I try to keep up with everyone else heading to the group of pups there is a constant thought on repeat in my head... stand up, don't fall, stand up, don't fall. I was so grateful to have knee pads on! :)

The Gorbatch rookery - rocks, rain and rubber boots..... what a combo.
I asked plenty of questions prior to this trip and felt fairly prepared to head to AK but the one thing I wish they had told me was to go to the gym... A LOT! This is quite a work out. We start our day at 9AM and finish when we get to the end of the rookery. For the next two days those rookeries are Reef and Tolstoi. Some days will be shorter than others but everyday is both energetically exhausting and exhilarating. Everyone helps each other out though, so if you haven't sheared enough pups and someone else has finished, they will shear one for you. This is a team effort with a common goal: Find out what is happening to the Northern fur seal population.
One of the highlights of the day is lunchtime. No, not because I get to sit down. It is because we eat right out on the rookery. We usually move up to the haul out area and find a place where the sub-adult males are not snoozing. However, it is close enough to them to observe their behavior and take some pictures. Here I am with a few young males relaxing in the background. I may be tired but pauses in the day like this one give me a chance to reflect on why I am here and how amazing these animals are, and that is enough to push through the afternoon.
