The Grasshopper Sparrow is a small sparrow (4.5 inches in length) with a short tail (image 1). The name of the bird is based on its diet and its song (two short notes followed by a high, thin, insect-like trill). Grasshopper Sparrows have a large, conical bill and a large, flat head (images 2 and 5). There is an orange-yellow spot in front of the thin white eye-ring (images 2, 3, 5, 7-9). Other notable features of the head are the buffy supercilium, the narrow, white crown stripe, and the dark brown lateral crown stripes (images 3 and 4). Adults have a light brown breast and a white belly (images 2, 4, 5, 8 and 9). The underparts are unstreaked (images 2, 5, and 9) or at most faintly streaked (image 6). Upperparts are streaked with brown, grey, black and white (images 1, 3, 4, 6-9). Territorial Grasshopper Sparrows will readily sing from open and exposed perches (images 8 and 9).
In Florida, Grasshopper Sparrows reside in some not-very-accessible locations (small, stunted saw palmetto and dwarf oaks with interspersed bare ground and sparse grass). I had no success trying to find them in Florida and was delighted to be able to see and photograph these birds in the western grasslands.
Photo #2 was taken with a Nikon D500 camera, 500mm f/4 lens with a 1.4x teleconverter attached. All other photos were acquired with the Olympus OM-D E-M1 Mark II camera, a 300mm f/4 IS Pro lens with a 1.4x teleconverter attached.
