The late Colin Bibby’s classic text Bird Census Techniques is currently on offer from NHBS at £31.99, a saving of £22 off the usual price.
Though over a decade old now, it is still the primary text for both professional and amateur ornithologists interested in the wide range of methods used to survey wild birds. Each technique is described in detail along with their shortcomings.
This may be a good time to add this interesting and useful text to your bookshelf.
The offer closes on 31 March 2011.
