This afternoon we went out on our catamaran to see what we could find out in the big blue. Not far from our base in Ponta Delgada our lookout had seen some blows from a baleen whale. At this time of the year we have several baleen whale species migrating past (mostly fin whales, sei whales and blue whales), so we were curious to see which species it was. It wasn't easy work...in the begining we only had distant blows, and based on the behaviour we guessed we might be dealing with a sei whale. We tried for a while to see this whale but eventually we had to give up. We tried to search for something else in another area and luckily it didn't take long for one of our biologists to spot a blow not far from our boat. This whale turned out to be easier to track, as it was coming up to the surface for a few blows each time. It was a fin whale, the second largest animal in the world! We tracked the whale for a while, trying to predict where it was going to surface next (something which is not always easy). A couple of times the whale surfaced near our boat so our patience paid off. What an adventure!
