I heard them before I saw them. I stood on a vast expanse of cracked earth, the air crisp with a hint of salt, as a distant trumpet chorus rolled towards me. The shrill bursts tore at the pre-dawn gloom, melancholy even in unison. Louder now, a tottering &lsquoV&rsquo of specks against the pale pink sky. Then a blur of grey and black and the slap and whoosh of a thousand wings as the common cranes washed over me in waves. From their night roost in the wetlands of Chari Dhand out into the chapped earth of the Banni grasslands for a day of foraging.
