Mating can start as early as late April but peaks in mid-May. Males will sing from the cover of dense grasses, perched on tall grass or in flight. Clutches range from two to six eggs with four being the most common. Incubation is done solely by the female, though both parents aid in feeding. Incubation lasts an average of 11–13 days. Hatchlings are altricial with dull brown downy patches. Pairs will have one or two broods per year. Due to the secretive nature of this bird little is known about the period of time between hatching and fledging.
