Bird-A-Thon Took Place

5PM Friday May 16 - 5PM Saturday May 17, 2025

How Many Species Will We Record?

84 Species were tallied in the 24-hour period! 

Highlights included spring warblers such as American Redstart, Northern Parula, Bay-breasted and Blackpoll. Three Red Knots were a shorebird highlight; a Black-necked Stilt was also a good find. The Sandhill Crane was spotted. Also included were all three corvids, three species of swallows, three types of tern, and three species of plover.

The birdathon raises money to help maintain the Edith F. Andrews Ornithological Collection, composed of over 1500 study skins prepared from salvaged birds. They are used by researchers and teachers.

Anyone birding on Nantucket during the Bird-A-Thon window is welcome to participate. MMA Members and Non-Members and Nantucket residents and non-residents can participate in the Bird-A-Thon by donating however, only birds physically observed and counted on Nantucket qualify for the official count!

All donations to the Nantucket Bird-A-Thon support the MMA’s conservation of its renowned Edith F. Andrews Ornithology Collection and activities related to the MMA’s work on bird conservation education.

Birding Guidelines

As always, this event serves as a reminder of the variety and abundance of wildlife that surrounds us and our responsibility to preserve the habitats of our beautiful and varied bird species. We ask our participants to please:


  • Try to avoid disrupting the natural behavior of the birds you are observing. For example, keep plenty of distance between you and any active nests, and refrain from using sound playback to mimic bird calls.
  • Stay on trail paths and do not "bushwhack."
  • Only record birds you can identify within the time period.
  • Check for ticks at the end of your birding expedition.
  • Have fun!
