On my second day in Boston I headed for the coast. I made the hour long walk to Castle Island Causeway. The causeway reaches out into the Atlantic Ocean creating rocky shore and beach habitat for birds and other marine creatures.
Starting on the south end of the causeway I worked my way north. On any pier jutting into the ocean there were Double-crested Cormorants and Herring Gulls. As far as species diversity I was once again disappointed. The beaches looked incredibly hospitable to migratory shorebirds but they were mostly empty. In addition to empty beaches, the ocean out past the causeway was also empty with the exception of a few gulls and cormorants. Perhaps the time of day factored in as boat traffic was persistent.
With few species on the shorelines I turned my attention to the gulls floating along inside break walls. I got great looks at Great Black-backed Gulls which are by no means rare in New England but can be rare in Wisconsin. Ring-billed gulls and a few Laughing Gulls were also present.
Walking along the edge of Castle Island I spotted a few Barn Swallows heading south along the ocean and my only shorebird species of the whole trip: A Black-bellied Plover. The plover was sitting on some rocks lining the causeway that slanted into the water. Near this area there was a lot of kelp and other plant matter washed up which looked like great habitat.
I made one more pass around the causeway but came up empty for new species. Overall I was disappointed with my lack of species at Castle Island but it was nice to be out at the ocean.
Badgerland Birding has officially reached the east coast. Boston, Massachusetts to be more specific. Even in the heart of one of the largest cities in the world there are birds to be found. Yesterday I stopped at the Boston Commons and Boston Public Gardens in search of some possible early migrants. The Boston Commons and Public Gardens are essentially the closest thing the city has to New York’s Central Park where there are ponds, grass, and trees. The two areas make up one large section of greenery in a sea of human civilization and are separated by a single road running in between.
The first birds I noticed were classic big city birds: The Rock Pigeon. These birds can be found all over the city and fly from building to building searching for scraps of food. Two other feral species were also present in large numbers, the European Starling and the House Sparrow. These three species easily made up over 75 percent of the individual birds in the Commons but there were some other more natural species as well. In the Public Garden the high pitched call of Cedar Waxwings could be heard. In the trees near the Waxwings were some warblers including Yellow, Black-and-white, and two feisty Common Yellowthroats that kept chasing Common Grackles away from their tree.
The trees where most of the birds were congregating surrounded a lagoon that also played host to many birds. Most of the birds on the water were Mallards but some Double-crested Cormorants were able to find spots to dry their wings. Also in the area was a single Mute Swan. The swan didn’t appear injured but was still on the lagoon later in the day so it may be a regular visitor.
Late in the day when the sun was starting to go down, I went back to look at some of the monuments and statues near the lagoon and the garden was buzzing with the chattering of hundreds of Chimney Swifts flying overhead.
Overall, the birds at the Boston Commons and the Boston Public Gardens were numerous, but the diversity was lacking. The area provides a stop for migrant birds flying over stretches of city and creates a permanent home for other birds more accustomed to urbanization.
