The effectiveness is case by case. In most cases (Kam Tin Bypass, KFBG), it works quite well. Otherwise, it is not recommended in a number of countries.

Oh, we are talking about two diff scenarios - (1) windows in a house and (2) typical transparent noise barrier along highways.

For (1), yes I agree stickers may not perform well in some cases  but our experience here indicates it could significantly reduce the no of cases. My estimate is from about 5 collisions per yr to nearly once every two yrs.

If it is a house and collision still occurs after putting on stickers, pls fill the gap with some decorations (photo frames, pine cones etc). We tried this before (stickers + cones) and it works very well.   

For (2), our understanding from the Kam Tin Bypass case around 2004 suggests it also helps to cut down the number of collision. It used to kill a lot of birds (spotted doves, flowerpeckers, warblers....) After put the stickers on, dead birds have not been reported for a long time.

Putting stickers on transparent noise barrier is now a standard practice for new highways, e.g. Deep Bay Link and highways around Tsing Yi.

Dylan,

Sorry not available in the market. So, it must be DIY. The falcon silhouette is shown here.

Alternatively, you could make a template first and then spray with the snow spray as a temporary measure.

That's why it is "case by case". This kind of issue is always confounded by a number of factors.

For the Shap Pat Heung Road case, there are two rows of transparent noise barriers - one higher and one lower. These two rows of windows may cause "illusion" to the birds and so they may think there is just one row of window. Just speculation.

lalan,

Grateful if you could mark down the locations of most dead birds on the photo. This fact is useful for futher discussion.

THX,

Captain
