We were very lucky to be joined by one of Ireland's best known birders. Killian Mullarney is probably best known for his painstakenly accurate illustrations in the Collins Bird Guide but he is also an identification expert, tour leader and member of The Sound Approach. We ask how it all started, how and why he began to draw birds, the genesis of the famous Collins Guide (now entering its 3rd edition) and the new Sound Approach book on waders.
