Project Overview

Window collisions are a surprisingly significant source of bird mortality in the US, causing over 100 million casualties annually. While programs exist in most major cities to study and mitigate this problem, we are only beginning to understand its scale in Boston.

That's why we're seeking volunteers to help monitor bird-window collisions in downtown Boston. Volunteers walk routes through the city, documenting or collecting window-collision victims, and reporting their data to Mass Audubon. 

Survey areas include:
Boston Common • Copley Square • Post Office Square • East Cambridge • Downtown Crossing • Seaport • and others!

How to Participate

Spring 2020 data collection period is April 11–June 2.

By volunteering as a citizen scientist, you can help us collect data on how window strikes affect birds and rescue birds that survive collisions. 

All volunteers should be able to commit to 1-4 shifts per week. Surveys will take anywhere from 15–45 minutes to complete. 

We are seeking two types of volunteers:

  • Monitoring Volunteers: Walk a fixed route through the city to collect window-strike victims and transport them to the Harvard Museum of Comparative Zoology, or freeze them for later pickup by Mass Audubon staff. This role is the most useful to our data collection efforts. 
  • Surveying Volunteers: Walk randomized routes the city, carefully photographing and documenting window-struck birds, and recording your route and time effort.
