Join us at the ROM on April 22nd, 2020

POSTPONED UNTIL FURTHER NOTICE DUE TO COVID-19

Each Spring, thousands of birds, which died from building collisions in the Greater Toronto area, are laid out on display at the Royal Ontario Museum. These birds were collected in the previous year by FLAP Canada volunteers. This annual exhibit has proven to be one of FLAP’s most effective techniques for raising awareness on this leading cause of bird death and has inspired other FLAP-like initiatives across North America to hold similar exhibits in their communities.

Please join us at the ROM on April 22nd for our 20th exhibit called Paneful Endings as we display over 2,000 bird casualties from over 90 species, including some Species at Risk such as the Canada Warbler and Wood Thrush. Our staff and volunteers will be available to speak with you about how you can help prevent bird/window collisions at your home and workplace.

What happens to the dead birds recovered?

With a scientific permit from Canadian Wildlife Service, our in-field volunteers recover thousands of dead birds throughout each Spring and Fall migration season that have died in collisions with windows and buildings.  Annually, we:

  • document the species of each dead bird, the location of the collision and hazards at the location that contributed to the bird’s death
  • tag and freeze dry or store in a common freezer until the end of each migration season
  • sort  and document the dead bird collection according to their species
  • arrange the dead birds in an annual, one-time display
  • photograph the arrangement for a visual record of bird mortality rates
  • use the images for awareness, education and research
  • train volunteers to help them develop bird identification skills

Bird Collision Data

We input our collision records into our community science database used worldwide by ornithological and environmental research institutions.

Bird Species List

Since 1993, we have documented over 85,000 birds of 172 species from a handful of buildings in the Greater Toronto Area.

Museum Specimens

The Royal Ontario Museum (ROM) receives a donation of dead birds for purposes of research and education, including:

  • Study skins: for permanent and teaching collection
  • Skeletons for study
  • Tissue and feather samples
  • Gallery displays and mounts

The ROM also distributes the birds to universities, and wildlife and naturalist organizations for similar purposes:

  • University of Guelph: genetic bar coding, West Nile Virus, nano-tagging
  • Canadian Wildlife Service: skins used for workshops
  • Ontario Naturalists: classroom workshops
  • University of Toronto: teaching skinning to students
  • Trent University and Queen’s University: tissue samples for molecular research
  • High Park: specimens for identification workshops
  • Numerous Artist: used for subjects for artwork
