Fall 2019 Findings of Calgary Surveys
During Fall of 2019, our volunteers conducted standard surveys up to 3X per day for a two-month period of time through the downtown core of Calgary, Alberta. Each survey, data was collected on the number of strikes found (whole birds and bats, living or deceased), their location, evidence of strikes (feather piles), and outcome when live animals were rescued.
Our volunteers located:
- 72 whole birds: 18 of which were alive and 94% were rehabilitated successfully.
- 35 piles of feathers or other portions of deceased birds indicating strikes.
- Five (5) bats: All were found alive. 4 were rescued and rehabilitated (1 evaded rescue)
On our Fall surveys, we quickly learned which buildings would have strikes and which would not. Multiple species were affected. Most were migratory birds.
Our intention is not to shame or place blame. We have no reason to believe that businesses are intentionally causing harm. It is reasonable to believe that most are unaware of the number of strikes that are occurring. We will be making this information available (on a per building basis), along with information regarding potential mitigation strategies.
Please note: the actual numbers of birds and bats affected by buildings during Fall 2019 is likely much higher than those found on our surveys. We are only on site at each building for a few minutes before carrying onto the next. We are also on site at only a small proportion of the potential buildings. Furthermore, scavengers such as magpies and crows will quickly consume a stunned bird or disorientated bat. Also, it is expected that cleaning staff routinely pick up any carcasses.
