The Grasshopper Sparrow (Ammodramus savannarum) is a small passerine bird that can be found in North and Central America. These sparrows are highly migratory and breed in the northern United States and southern Canada during spring and summer, before migrating to the southern United States, Mexico, and Central America during winter.
Grasshopper Sparrows are known for their distinct call, which sounds like a buzzing insect, and they often breed in grasslands and prairies. They are ground-nesting birds, building their nests in the grasses and shrubs typically found in these habitats. Grasshopper Sparrows are sexually dimorphic, with males typically being slightly larger and more brightly colored than females. Males have a brown and white striped head, with a yellow patch above the eye, while females are duller in color.
Grasshopper Sparrows feed primarily on insects, seeds, and small invertebrates. They are solitary birds, but may be found in small flocks during migration. They have a unique feeding behavior, in which they crouch on the ground and wait for prey to pass by before pouncing on it. They are also known to fly low over the grasses to catch prey in mid-air.
The population of Grasshopper Sparrows has been slowly declining due to habitat loss from agriculture, urbanization, and development. Conservation efforts are being put in place to protect grassland habitats and increase the number of breeding pairs. Grasshopper Sparrows are a protected species under the Migratory Bird Treaty Act of 1918 and it is illegal to harm or kill them without a permit.
The Grasshopper Sparrow is a remarkable and unique bird that plays an important role in the ecosystem. As we continue to protect their habitats and ensure their survival, these charming little birds will continue to be a beloved sight to behold in the grasslands and prairies they call home.
