Like most grasshopper sparrows, their wings are brown, white, and grey in color, with patches of yellow on the alula and supercilium.
[7] The Florida grasshopper sparrow has a longer bill and tarsi than other subspecies, and lacks reddish streaks on its nape.
[7] As grasshopper sparrows are largely a ground-dwelling species, some bare ground is necessary as well to provide areas for movement and foraging purposes.
However, there are reports of at least two other subpopulations on private lands, which Audubon Florida plans to acquire or give conservation easements for.
The population decline is attributed to hatchling predation by invasive fire ants, extreme weather flooding nests, loss of habitat, and competition with non-native species.
This decline has prompted the initiation of captive breeding programs by the Rare Species Conservatory Foundation and White Oak Conservation.
In 2015, 23 eggs threatened by nest flooding were transported to the Rare Species Conservatory Foundation, where 21 successfully hatched via artificial incubation.
By mid-June 2017, White Oak Conservation had produced 18 chicks from 3 pairs of adults that were born in the wild and their five offspring.
[17] Captive breeding has been hindered by diseases caused by an infectious gut parasite, though solutions are being worked on.
