Likes: (1) Packed with the details a birder wants at field. (2) Comparison with sub./other species gives good clarity for the field identification (3) Distribution maps of species are provided adjacent to the description advantageous to the birder.
Dislikes: (1) It could have made lighter in weight (2) Grey/small fonts gives difficult reading in dull light. (3) while comparing with other/similar species sometimes the main species description looses focus. (4) doesn't give details of breeding biology of birds like breeding time/nesting details/clutch size description etc. (5) Corners of book deteriorate faster as the soft cover. Edge protection needs to be done by the user.
