Ammodramus Swainson, 1827
The genus Ammodramus is a group of American sparrows in the family Emberizidae. Ammodramus is Latin for "Sand Runner." Typical of these thick grass and ground loving sparrows.
These birds are relatively small, with large bills, flat heads and short tails. They are usually found in grasslands or marshes and are often fairly inconspicuous. Most of their songs are insect-like.
Many of these bird species have declined in numbers due to habitat loss.
The full list of species is:
* Seaside Sparrow, Ammodramus maritimus
The fossil Ammodramus hatcheri (Late Miocene of Kansas, USA) was formerly placed in genus Palaeospiza or Palaeostruthus. The former may not be a passeriform at all, while the latter was eventually synonymized with Ammodramus as A. hatcheri scarcely differs from the living species.
