Hiking through mud, thick and slippery, puts a damper on anyone’s enthusiasm. Such was the case for my intern and me on a humid summer morning, making our way to our first Western Yellow-billed Cuckoo survey point. Slogging silently and grumpily down a soggy riverbed, my intern suddenly brightens, as if lit from within, and practically shouts and points hopefully “is that a cuckoo?” No, I reply, it is a Yellow-breasted Chat.
