On Sunday May 15 I led a bird walk in Bussey Brook Meadow in the Arboretum. As usual, the walk was hosted by the Arboretum Park Conservancy (APC), an organization that is largely responsible for creating a safe connecting link from the Forest Hills MBTA Station to the South Street Gate into the main area of the AA. The APC continues to maintain, in conjunction with the Arnold administration, this very naturalized area. Currently they are part of a larger community group that is planning a new bike and walking path which would connect the Roslindale commuter rail station to the Forest Hills T, running along the railroad tracks and through Peters Hill and Bussey Brook Meadow. With some luck, and of course some public and private funding, this extension of Boston green space could be completed in two years!
But our business on Sunday was birds. 26 people turned out at 8 AM and we scoured the trees and bushy tangles of this urban wild trying for almost two hours to find them. This is spring migration so we wanted to see some warblers, but that turned out to be difficult. At the beginning of the walk we could see a lot of action high up in the trees just leafing out, but getting on the birds long enough to identify them was tough. All we could tick off was a Black and White Warbler:
Black and White Warbler. This early migrant is most often seen climbing on the trunk and major tree limbs searching for insects.
Our only other warbler on the walk was the fairly common Yellow Warbler, which nests here. I think our best bird was a very cooperative Blue-gray Gnatcatcher. Someone first heard the high pitched nasal buzz of the bird, then we located it bouncing around in a vine-covered small tree.
The field marks for the Blue-gray Gnatcatcher are it’s relatively long tail and distinct eye ring. As it’s name suggests, it flits about catching tiny bugs.
The bird stayed close for some time giving everyone good looks. We later watched another bug-catching bird doing it’s thing, an Eastern Kingbird:
Eastern Kingbird. This large flycatcher is easily identified by it’s dark gray head and body, white breast and white-tipped tail.
As the walk progressed we saw several of these birds. We also had another flycatcher, Eastern Phoebe, at the end of the walk.
The Eastern Phoebe is a very early migrant. Smaller than the Eastern Kingbird, it has a habit of bobbing it’s tail, a good field mark.
We saw and heard many Baltimore Orioles, a welcome spring visitor.

On a scouting trip earlier in the week I located a new oriole nest just above the path, but today it couldn’t be found; perhaps a victim to strong winds lately. We did however find an active robin nest, and watched two Mourning Doves building a nest as well. The diverse habitat of Bussey Brook Meadow and marsh provides nesting territory for at least two dozen species of birds. In addition, nest boxes erected there are regularly used by Tree Swallows; we watched a pair enter and leave one box:

After the formal walk ended several of us walked down the edge of the meadow, along the route of the proposed Roslindale/Forest Hills path mentioned above. There we heard a Wood Thrush calling from the woods across the road on Hemlock Hill. What a lovely sound:
