Nightjars, Potoos, Frogmouths, Oilbird, and Owlet-nightjars of the World by Nigel Cleere. First published 2010.

I’m still pretty new at this birding thing, so I’m still enjoying learning about the history of the hobby and of ornithology. The more I read, the more I come to understand everything I *don’t* know about birds and birding. And one area where I have been woefully mistaken is in the base of scientific knowledge that exists regarding birds and their behavior (I imagine this crosses other biological fields of study)! I kind of have the idea that everything is there for me to learn if I just find the appropriate book or the right mentor, but instead I am constantly surprised at how little we (meaning human beings) know about birds at all.

This fact struck me again as I perused Nigel Cleere’s Nightjars of the World, a beautiful and comprehensive resource full of outstanding photography. I was surprised to learn that fully five species of nightjar are practically unknown to science – their very existence is only known from a single (dead) sample individual. Wow! Other species covered in the book are also shrouded in mystery – to be expected from primarily nocturnal birds, I imagine. Vocalizations of many are unrecorded, and nesting behavior and eggs are practically completely unknown regarding eight of the covered species.

Yawning White-winged Potoo

Before going into species accounts, which make up the bulk of the book, the author provides general information about the bird families covered, including coverage of plumage types and camouflage, body typography, breeding information and feeding behaviors. This section is full of photographs, showing the camouflage strategies, actual nightjar nests and chicks, etc. Knowing very little about nightjars and their allies, I found this part of the book to be fascinating.

Lesser Nighthawk photographs

Following the introductory text, each species is presented on two or more pages. Details like size, identification tips, habitat and vocalizations are described, and a range map is shown. The species conservations status is also listed. The following page contains photographs of the species. The photos in this book are amazing, large and vibrant. There are more photos of some species (the Marbled Frogmouth is covered with seven full-page pictures!). For several of the lesser-known species, the provided photos are of museum specimens.

Black-shouldered Nightjar species account

The species are presented in taxonomic order. The only complaint I have is that there is no easy way to find all of the birds native to a particular location. However, this reference is not meant as a travel guide, so this one complaint is a small one.

The book is a joy to page through; the photographs are truly marvelous and the species are fascinating – and mysterious. I leave you with a quote from the book:

There is much to learn about this enigmatic group. But from the little we do know it is clear that the [nightjars and allies] exhibit a number of remarkable features that would richly repay further study.

I give Nightjars, Potoos, Frogmouths, Oilbird, and Owlet-nightjars of the World 5 Goldfinches out of 5.
