'Baby boomer journalists who write books about struggling to look after animals' is a surprisingly common thing, and I'm not sure why.
Most people don't have anecdotes about decapitated ducks or not knowing what a ruminant is because they do research before becoming responsible for animals. Writing about how you're mystified by duck behaviour might be amusing, but all you're really doing is showing your ignorance.
Books like this really contrast with something like 'How to speak chicken', which is written by someone who expends a lot of effort in learning how to understand their animals. They're not just furry/feathery additions to your garden, they're living creatures that you are legally required to protect and nurture.
