In April, nearly every day of observing at MB brings a special treat. Today, the air is raw and the wind is strong, but my internal complaint about the slowness of spring is interrupted by the sight of a bird with long, crooked dark brown wings moving high over the water. As it comes into full view, its underside is white, its wings banded black and white with dark patches at the crook, and its eyes sport a black band. This first Osprey I have seen this season catches a column of air and soars in large ovals above the water. My delight increases as it draws its wings up, extends its feet down, and descends to the water feet first to fish, hovering on beating wings. It pulls up out of the water having failed to catch its fish and resumes its soaring. The air column takes it downstream out of site and I move along. But moments later an osprey comes up from behind, catches a column of air and soars gracefully ahead of me. I tell myself it is likely the same bird, but then another soars into view, then two more join in an aerial ballet.So far, spring has been cool and wet, but birds are easy to find at MB. Who is back? Red-wing blackbirds, Crows and Robins. Earlier this week I estimated 300 robins were hunting worms on the lawns. If the lawns look a bit torn up this is because they have thoroughly aerated the grass while removing the worms. Male Redwing Blackbirds claim territory in the hedge for nesting when the females return. MB’s riverfront location makes it appealing to shorebirds- Killdeer, American Woodcocks, and Snipes are using their long bills to remove insects from the moist leaf litter on the ground. Duck are swimming by, often in pairs, looking for places they might nest. In addition to the usual Mallards, Ring Necked Ducks with purple heads and rings on their bills (not their necks), and Hooded Mergansers with crests like large white sails outlined in black swim by. Double crested cormorants fly through and will shortly perch in groups on the floating orange stanchions across the river. Gold finches flit through in groups. Song sparrows give daily concerts. From here through May it only gets better.
Note: Jeanne, who’s leading the wildlife inventory of the park, will be leading a FREE bird walk there May 6 (rain date: May 7), at 7:30am, with CRWA birder Matt Marshall. Meet at the BU Bridge, facing the park.
