I’ve been a strong critic of glass buildings in hot places like Mumbai or Delhi but recognise that it may be appropriate in more temperate climates. One thing that had escaped my attention, though, was the hazard that such buildings have become for birds.  The thing is, birds don’t see glass façades the way we do – in fact, they hardly see them at all – which is why they are known to fly straight at a glass building and be killed or maimed by the impact.

It costs a lot more to make a bird-friendly glass façade but, at least, we now know that such an option exists.
