Abstract

• Study on the breeding biology of avian species is the key to understand their behavior, demographics, and population dynamic. Thus, the present study was intense on this field in little know of Myanmar endemic species, Burmese Bushlark (Mirafra microptera) to fulfillthe regional data gap. The monthly field survey was conducted from March 2017 to September 2019. Fifty-one nests were found in three years study periods. The breeding seasonof Mirafra microptera was from the beginning of March to the mid of September with 1- 2 eggs in clutch size. Twenty-six eggs out of 100 eggs hatched with the hatching success (26%),fledgling successes (81%), breeding success (41%), and crude breeding success (21%) recorded for three years study periods. Breeding success was a significantly negative relationship with temperature and a positive relationship with humidity.
