  • Arlington Reservoir

    Visit Arlington Reservoir and the adjacent Lexington Community Farm to search for late winter lingerers and early migrants. Cosponsored with Menotomy Bird club.

  • Mass. Audubon Boston Nature Center

    Join us to observe resident birds and early spring migrants in a unique urban habitat that is a favorite for many bird species, including uncommon and rare birds. Birders of all levels will enjoy this walk. The trails are flat and easy to walk. Be sure to wear a hat, waterproof footwear, and bring water.

  • Mt Auburn Cemetery

    Mount Auburn Cemetery is lovely in all seasons.  In late March, we may see the very earliest migrants from the south (Red-winged Blackbird, others) as well as the remaining seasonal visitors from the north (e.g. White-throated Sparrow, Dark-eyed Junco).  And our usual year-round resident species will have just started to sing!
