The following pen & ink piece was created as a sample illustration for the Toronto-based organization F.L.A.P (Fatal Light Awareness Program). Since 1993, FLAP has coordinated a volunteer intiative to pick up the birds that have collided with city buildings. This effort has amounted to tens of thousands of birds since the FLAP was founded in 1993. The birds that are found alive (less than 40%) are brought in for rehabilitation and later release.
An estimated one to ten birds die per building, per year, by flying into glass or other reflective surfaces during the day or at night. This means that, without better safeguarding (such as BirdSafe building standards and effective bird deterrant technologies), the City of Toronto has over 950,000 registered buildings that could potentially kill over 9 million birds each year.
The organization also coordinates several other valuable initiatives to do with bird safety, awareness and education. See more: http://www.flap.org/who-we-are.php
