April is the peak month of spring migration for millions of birds, so the ongoing eruption of the Icelandic volcano, Eyjafjallajökull, presents hundreds of millions of birds with an unusually challenging set of circumstances as they fly to their northerly breeding grounds. But when a reader asked me how volcanic ash affects birds, I had no ready answer.
