  • Woodcock Walk, North Easton

    North Easton - Edwin A. Keach Park Chestnut Street, Easton, MA, United States

    From the playground, we will walk a short distance to an open area where we can observe 2 fields for Woodcock. Sunset is around 6:30 pm so bring a camp chair and relax for the Woodcock flight.

  • CANCELLED Pine Hill Road Grasslands (was rescheduled from March 14)

    Lancaster - Pine Hill Road Grasslands Pine Hill Road, Lancaster, MA, United States

    We scheduled this trip too early. It was a mistake in retrospect. We are cancelling this trip. The birding will get better in mid to late April. We have trips in May and June that will be in prime season for this location.

  • Mount Auburn Cemetery, Cambridge

    Mount Auburn Cemetery 536 Mt Auburn St, Cambridge, MA, United States

    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!

  • Franklin Park – Scarboro Pond

    Boston - Franklin Park Tennis Courts (Meeting Spot) Roxbury, MA, United States

    We will look for early spring migrants in Franklin Park. Beginners welcome and encouraged. Expect to walk up to 2 miles on paved paths. Loaner binoculars available. Co-sponsored with the Franklin Park Coalition and Franklin Park Tennis Association.
