The Sound Approach to birding 2 is accompanied by over 300 sounds, *** illustrations and *** photographs, as well as sonograms that help to visualise the sounds you're hearing. There is also an accompanying app, so you can enjoy bird song on the go and listen and learn as you read.

We explore new theories of bird sounds and how they have evolved, with much of the book taking on a Bryson-esque feel that looks at science, history, personal adventure, humour, introducing even top birders to new theories of oscines, cultural evolution, biological evolution, migration and how bird sounds spread from Australia all around the world.
