Just finished E.A.R. Ennion’s “Adventurers Fen” - written in the 40s and describing the fen’s context and the evolution of its ecology through phases of development and in effect managed rewilding in the four preceding decades. A short book, with a really authentic feeling of intimacy and fascination, the more poignant for both describing its development again in the Second World War and for the allusion in the preface to that and to the likelihood of it freeing itself again - and knowing what it is like today.

Three audio spectrograms of a Bewick's wren recorded within a minute. The visual representation makes recognizing the bird easier than the sound, at least to me. Notice that the distinctive chirps come as a set of three, four, and five. The bird either can't count or it can count and changes this feature of it's call for reasons a mere mammal can't understand.
