The 266 commoner species of Delhi and Haryana are mapped to show their distribution and seasonality. Each of the4se species has a full page with two photographs as well as the maps. The text focuses on habitats and behaviour and complements the more descriptive information in standard bird identification guides. It also compares the status of the birds in the early 21st century with that reported by Usha Ganguli over 30 years ago. A further 252 species which are either scarce or very local in the two states have shorter accounts. Some of these are illustrated by photographs. There is also a list of 45 species that have not been recorded since 1970. The illustrated, introductory chapters describe the geography of the two states, trends in the study of birds here and some rural Haryana folk tales involving birds.
