Two more Canadian birds are now on the endangered species list. While I would like to blame Monsanto, I fear we are equally negligent because of reflective glass and diminished habitat; there are no Barn Swallows lining telephone wires anymore, because there no barns.

This sunny walkway is a bird killer in Ottawa City hall.
There's a lack of awareness that the birds are in trouble. I see dead birds on concrete sidewalks almost every time I go into the downtown core of Toronto. Sanitary engineers employed by these glass office towers must dispose of at least one carcass a day. Bird strikes happen not because the birds want to get inside the buildings, or because they are crazy, but because they see a reflection of the open sky and so believe their path is clear. Newly developed technologies like Ornilux glass let birds see spider webs in window panes, even in strong sky reflections while humans see nothing on the inside and have to look hard to detect any difference on the outside. Bird friendly building treatments also include wire strips to prevent nesting in hazardous areas and maybe the site encourages nesting in safe and healthy areas. The place has proper lighting, and unusual angles that are friendly to flying birds.

What are the known bird Friendly buildings in Toronto?
Is it true that condo buildings poison pigeons on rooftops?
