HBA Season1 Feb2025

A Hyderabad Bird Atlas(HBA) is a citizen science project aimed at systematically documenting the bird species present in and around the city of Hyderabad. This work closely follows the already completed Coimbatore, Mysore, Pune and the Kerala Bird Atlas.

 

• Bird survey needs to be done twice in a year (Winter – Feb & Summer – Jul) for a minimum period of 3 years

 

• Outer Ring Road(ORR) is taken as the border limits for the survey

 

• The different habitats like woodlands, grasslands, wetlands, open natural ecosystems and urban landscapes are selected randomly

 

HBA will cover 11% of the city

 

• City is divided into grids of  6.6km x 6.6km. Total 45 grids

 

• Each grid is further divided 4 quadrants and 36 subcells(1.1km x 1.1km)

 

• 4 random subcells(1 per quadrant) are picked for sampling (4 out of 36)

 

• Total subcells needed to be sampled are around 180 (4X45)

 

• 4 checklists of each 15 minutes are created from each subcell(4X15X180 = 10800 minutes (180 hours))

 

• Total checklists for a season 720 (4X180)
