Jef led three of us on an urban nature walk around a very urban beach. Savin Hill Beach in the Dorchester neighborhood of Boston is bordered by Interstate 93 and William Morrissey Boulevard. We were surprised at the diversity of water birds we found, including a few I hadn’t previously seen in the Boston area.

Spectacle Island Birds: Tree Swallows and Laughing Gulls
We saw quite a few birds last Monday on our trip to Spectacle Island, including a species of gull for the first time. We counted 45 double-crested cormorants near the island’s shores.
Tide Pools of Spectacle Island
The last time I explored tide pools on the Boston Harbor Islands, I was taking Bruce Berman’s Snails to Whales class. We learned the geography of the Harbor, visited the islands, learned about the clean-up, and saw so many creatures I never knew existed in this area. We saw a few of those same creatures on Spectacle Island this past Monday.
Taking cover near a rock, this Asian shore crab (Hemigrapsus sanguineus) does its best to remain hidden. This non-native crab can be distinguished from others in our area by the three “teeth” it has running down each side of its shell. Other species have at least five.
Tide Pools at Wingaersheek Beach
We left our campsite on bikes and rode to Wingaersheek Beach. If you arrive on bicycle, you will not be charged an admission fee. Bicycle parking is scarce, though, and we had to lock our bikes halfway up a “resident parking” sign.
We arrived near low tide and got to exploring the tide pools around a few large boulders. Even with its clever camouflage, a sand shrimp (Crangon septemspinosa) could not hide from us. This species of shrimp is commonly found in our shallow waters. Its color varies, probably to better blend in with its sandy surroundings.
