Bird Pellets (a Complete Photographic Guide)

Dissecting bird pellets is the ultimate fun and scientific way of discovering what a bird has been eating. This guide showcases the pellets from a range of different bird species and outlines how to identify what is found in them, in particular small mammal skulls and bones.

This book is the first comprehensive guide to bird pellets, the undigested remains of food that form together into a ball or sausage-like shape and are regurgitated. It showcases the range of pellets that different bird species produce, including owls, hawks, falcons, corvids such as ravens and magpies, as well as waders – and even garden birds! The common items found in them, such as small mammal skulls and bones, are analysed in detail, with the discussion accompanied by numerous colour illustrations.  

The book progresses methodically from an introduction to pellets, covering what they are and how they are formed, to instructions on dissection and analysis and how this can be used in research, followed by a closer look at the pellets of each bird species in turn – from the golden eagle to the dipper. We learn how to identify the remains of small mammals including bats, as well as reptiles, amphibians, fish, invertebrates and of course other birds.

Dissecting bird pellets and identifying what is inside can be an important tool for discovering what birds are feeding on as part of more detailed diet studies. It is also an activity often delivered at family-friendly events or in schools by wildlife organisations. Extracting information from pellets also has sound scientific value: while it does not capture everything a bird has been eating, it still goes a long way in revealing the diet of birds and how this may change over time, in different habitats and different parts of the world.

Ed Drewitt has created a great guide here, and to date, apart from a few leaflets and magazine articles, there has not been enough available information on bird pellets to allow you to see what a bird has eaten... Not many adults (other than professionals) examine pellets but many school children do and this book is laid out in an easy style that allows anyone to work out what they are looking at.

...most will be unfamiliar with the range of species which produce pellets and how to go about finding them. Ed Drewitt’s Bird Pellets aims to fill this gap and goes about doing so in a thorough and digestible manner on a (literally) indigestible subject... a useful reference guide for any field naturalists.

Ed Drewitt is a freelance naturalist and learning advisor. He specialises in showing people wildlife and helping them to learn birdsong. Ed has been collecting bird pellets, skulls and feathers since he was seven years old. Since 1998 he has been studying the diet of urban-dwelling peregrines and is author of both Urban Peregrines and Raptor Prey Remains.

Yet another masterpiece by Ed Drewitt. This is the book I wish I’d had as a 10-year-old with a bath full of barn owl pellets!
