Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Miranda Krestovnikoff presents the house crow, native of southern Asia. Leggier and longer-billed than the slightly larger European carrion crow and having a charcoal grey bib and collar and raucous call, these are common birds in towns and villages from Iran through India to Thailand. As scavengers they eat almost anything, which is how they've come to live alongside us. We provide water as well as food and have introduced the birds into areas of the Middle East and Africa. Although they don't fly long distances, the crows often hop aboard ships and arrive in foreign ports. Ship-assisted house crows have the potential to spread around the globe, a beautiful example of avian exploitation of human activity.
