This week’s theme is Seabird Specialists!  Boston has many seabirds, which our sailing students often see out on the water.  Cormorants, gulls, and terns are among the most frequently noted species.  Though seabirds might not be the most glamorous creatures, they play an important role in the ecosystem and are actually more interesting than they might appear.  For example, Artic Terns, who often stop by Boston Harbor along their annual migration route, have one of the longest migrations (by distance) of any bird- traveling about 25,000 miles each year!

Cormorants are one of the animals that spend the most time in the water around the sailing center and tend to raise the most questions among our sailing students.  These sleek, black birds are some of the fastest and deepest diving birds in the world!  Most commonly, cormorants are spotted sitting on mooring balls and rocks with their wings outstretched because their feathers are not waterproof, unlike other birds whose feathers repel water to keep them warm.  Cormorant’s feathers intentionally absorb water to help weigh them down so they can dive deeper and faster to catch fish. 

Both cormorants and terns inspired this week’s activities.  More information on that coming soon!

This week is Crustacean Crusaders week!  We are lucky at Courageous that we have lobster traps along the dock that we can pull up so our campers can meet many sea creatures up close.  Among the common creatures that we find in our traps, most are crustaceans so our students are very familiar with local crabs and lobsters.  

Boston Harbor is home to many different crustaceans including barnacles, crabs, and lobsters, but our weekly activities focused on crabs.  After reviewing the characteristics of crustaceans, such as their jointed appendages, two pairs of antennae, and exoskeleton, we focused on the crabs found in Boston Harbor that are actually invasive species.  The European Green Crab and Asian Shore Crab are more common in Boston Harbor than some of our native species, such as Red Rock crabs and Jonah crabs.
