Last Day in Vonitsa



We all woke up bright and early this morning because we wanted to make the most of our last day in Vonitsa. We boarded the boat at 9:00am and worked on dolphin sightings until noon. What were you doing in New York when it was 9:00am in Greece?






During this trip we saw many exciting things. Joan spotted another sea turtle with its head poking up out of the water, we saw a pair of pelicans floating on the water, and we observed dolphins displaying arial behavior. What do you think arial behavior is? Two other types of behavior we observed were social and percussive. Can you guess what they are? Joan told us how we can determine if a dolphin is an adult or a juvenile. Juveniles are usually swimming right next to their mother and when they surface they bring their faces up out of the water. Adult dolphins usually do not do this. Juveniles do it because they are very curious about what is going on above the water's surface. I got to see two juveniles on my journey. Calves are much smaller and newborns are dolphins that have just been born.






Pollution in the Amvrakikos Gulf causes some newborns to die soon after birth. This is because the mother dolphin has ingested the poison in the water and when she feeds her baby her milk the baby is also poisoned. The first born suffers the most because all of the poison is transferred to it.









After a full morning on the boat all of the Earthwatch volunteers decided to take a trip to the Roman ruins in Nikopolis. We saw remants of a Roman church, a temple, and a stadium. This was an interesting way to end our time together.
