BirdSafe Maine

Birdsafe Maine is a statewide collaboration to raise awareness about the bird-window collision problem and encourage adoption of available solutions, through research, policy, design solutions, and education.  For more information, contact Advocacy and Outreach Manager Nick Lund.


The Problem: Buildings are not a natural part of the environment, and humans have disguised buildings in a number of ways to make them more deceiving, and deadly, to birds. The result is that millions of North American birds are killed each year in building collisions, another danger added to the growing list of threats to bird populations worldwide.

The U.S. Fish and Wildlife Service estimates that somewhere between 388 million and 988 million birds die from building collisions each year. Glass is the major culprit. Glass is both reflective — which tricks birds into thinking they’re flying into open sky or vegetation — and transparent — it appears invisible to a bird when lit from inside. All windows pose a threat, from those in the tallest skyscrapers to your kitchen window.

Solutions: Thankfully, there are solutions to this problem. The American Bird Conservancy recommends numerous architectural solutions, including screening; a de-emphasis on exterior glass; ultraviolet strips placed inside glass panels; exterior frits or stickers; and other measures.


Our Work: Maine Audubon and our partners are working to educate architects, home-builders, homeowners, state and local officials, and other concerned citizens about the bird strike issue. We are working on a number of fronts:

  • Portland Surveys

Maine Audubon volunteers and USM students are surveying routes in Portland during spring and fall migration seasons, walking in the early morning looking for evidence of building strikes. We have identified hundreds individual birds of more than 20 species on the streets of Portland, most often at the base of just a few problematic buildings. We are continuing to monitor the city, and new constructions, as well as work with building owners to remedy particular problems.

  • Statewide Information Collection

We want to know where birds are striking windows around the state. If you find a dead or stunned bird at your home or anywhere, we want to know about it. Please take a photo of the bird and send it with date and location information to BIRDSTRIKE@MAINEAUDUBON.ORG 

  • Outreach to the Architectural Community

Our partners at the Portland Society for Architecture (PSA) have helped us make strong connections to the local architectural community, and we are working together to educate and advise on particular projects. PSA has hosted a number of educational webinars and in-person gatherings to discuss bird-safe architecture and solutions for particular projects. We’re also in conversation on specific projects to help reduce the danger to birds, including the new Mid-Mountain Lodge at Saddleback Mountain, which is set to have some unique and state-of-the-art protections for local breeding birds.

  • Policy Solutions

BirdSafe Maine is taking our data and turning it into action. On June 17, 2024, the Portland City Council voted unanimously to approve a city-wide bird safe buildings ordinance. In 2023, Maine became just the fourth state to take statewide action on bird-safe architecture with the passage of LD 670, An Act to Protect Birds in the Construction, Renovation and Maintenance of Public Buildings. The new law will bring together stakeholders across Maine to develop guidelines for the bird safety in public buildings. Maine Audubon and our BirdSafe partners are looking forward to working with the city and the state to create sensible and effective guidelines.
