Project Overview

Window collisions are a surprisingly significant source of bird mortality in the US, causing up to 100 million casualties annually. While programs exist in most major cities to study and mitigate this problem, its scale in Boston is largely unknown.

That's why we're seeking volunteers to help monitor bird-window collisions in downtown Boston.

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

Fall 2019 data collection period is August 24–October 28.

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 must commit to 1-4 shifts per week. Surveys will take anywhere from 15 minutes to 1 hour 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.
