Birds of Malaysia

The book "Birds of Malaysia" does not appear to be written by Chong Leong Puan. Instead, there are several field guides to the birds of Malaysia written by different authors, including:

1. "A Field Guide to the Birds of Malaysia Including Sabah and Sarawak" by Lim Kim Seng, Yong Ding Li, and Lim Kim Chuah. This comprehensive field guide covers 829 bird species in Malaysia, including Sabah and Sarawak. It features over 170 plates with illustrations, detailed descriptions of identifying features, and information on taxonomy, habitats, breeding cycles, and conservation.

2. "Birds of Malaysia & Singapore" by Lim Kim Seng, Yong Ding Li, and Lim Kim Chuah. This guide is part of the Lynx and BirdLife series and provides an illustrated identification guide to the birds of Malaysia and Singapore.

There is no mention of a book titled "Birds of Malaysia" written by Chong Leong Puan in the available sources. Therefore, there is no key themes, plot summary, or critical reception to provide for such a book.
