A study on the conservation on breeding colonies of Bank myna, (Acridotheres ginginianus) was conducted
in district Jhang, Punjab during a period from February 2022 to November 2022. The aim of this study was to study
breeding biology, conservation status and natural hazards impact on insectivorous bird Bank myna. The total
population in the breeding colonies was estimated as 400.

The preferable breeding habitats of bird are bank of the
river, soil heap/ditches of brickfield and holes of culvert. Environmental calamities such as bank erosion and
flooding, drought and rain affect the breeding colonies. Human settlement near breeding habitats, hunting, collecting eggs and nestlings by children, and use of nets to prevent nesting at bank of the river are the main human impacts on the breeding colonies. Major threats are flood, children-fun, predators and human for its meat. Cluster method was used to study the breeding biology of Bank myna. In Bank myna, average egg weight was found 5.55±0.25 gm. The average length and width of the eggs were found to be 2.38±0.15cm and 1.91±0.10 cm. The average egg shape index was 80.48±4.06 and an average volume of a fresh egg was 4.57±0.74 cm3 .
