		Because they are habitat obligates and may not nest successfully in degraded salt marsh, they are susceptible to salt marsh loss and destruction.
		I will determine the distribution, relative abundance, and density of Ammodramus sparrows in New Hampshire salt marshes during the summers of 2004 and 2005.
		Finally, by examining a variety of abiotic and biotic factors that influence salt marsh sparrow nest success, I hope to provide valuable data that can be used to set appropriate management guidelines for these declining species.

	Family Emberizidae
		This sparrow is rarely observed because it rarely flushes and prefers to hide in the grassy meadows where it lives, but the male does sing from a higher perch.
		The fact it's breast is clean white with thick, dark markings helps distinguish it from Ammodramus sparrows and the very similar Vesper Sparrow, which are the other grassland sparrows with streaks on it's breast.
		This sparrow is not as shy as Ammodramus sparrows and lacks their pointy tails.

		The only remaining subspecies generally (but not universally) accepted are the Eastern Henslow's Sparrow and the Western Henslow's Sparrow, whose ranges are for the most part separated by the Appalachians

	Nelson's Sharp-tailed Sparrow - Central Park - Sept. 2002
		It displayed all the classical features of these Ammodramus sparrows - a flattened crown, narrow bill and bright orange triangle on the face surrounding a gray cheek patch.
		It is assumed that the usual subspecies of Nelson's observed in winter would be Ammodramus nelsoni subvirgatus corresponding to the subspecies that breeds in the extreme north-east and winters south of it's breeding range.
		The subspecies Ammodramus nelsoni nelsoni breeds in the upper midwest and winters on the Gulf Coast.

	NPWRC :: Area Requirements of Grassland Birds: A Regional Perspective
		We studied the relation between both species-occurrence and density and patch size by conducting 699 fixed-radius point counts of 15 bird species on 303 restored grassland areas in nine counties in four northern Great Plains states.
		Northern Harrier (Circus cyaneus), Sedge Wren (Cistothorus platensis), Clay-colored Sparrow (Spizella pallida), Grasshopper Sparrow (Ammodramus savannarum), Baird's Sparrow (Ammodramus bairdii), Le Conte's Sparrow (Ammodramus leconteii), and Bobolink (Dolichonyx oryzivorus) were shown to favor larger grassland patches in one or more counties.
		Although it is convenient to attribute declines of grassland bird populations to losses of native grassland, habitat loss is but the first of three main concerns involving the breeding grounds.

	Ammodramus - Wikipedia, the free encyclopedia
		The genus Ammodramus is a group of American sparrows in the family Emberizidae.
		Many of these bird species have declined in numbers due to habitat loss.

	Sharp-Tailed Finch
		This species and the Ammodramus maritimus spend the winter among the salt marshes of South Carolina, where I have observed thousands of both late in December, and so numerous are they, that I have seen more than forty of the latter killed at one shot.
		At that season, the neighbourhood of Charleston seems to be peculiarly suited to their habits, and there they are found in great abundance along the mouths of all the streams that flow into the Atlantic.
		Second, third, and fourth quills longest, first and fifth equal; tail graduated.

		This Seaside Sparrow (Ammodramus maritimus) is a member of the maritima subspecies, which breeds in the coastal tidal marshes of the northeastern US, from Massachusetts to Virginia.
		I’m going to be the teaching assistant for Field Ornithology this coming spring, and in an attempt to find some new teaching resources I have recently been introduced to the online Macaulay Library of Sound and Video, located at the Cornell Lab of Ornithology (thanks Karl!).
		I was able to find the subspecies of the Seaside Sparrow which I study in Florida by searching for the latin name down to the subspecific epithet (Ammodramus maritimus mirabilis).

	IUCN Red List of Threatened Species: Ammodramus henslowii
		IUCN Red List of Threatened Species: Ammodramus henslowii
		Ammodramus henslowii breeds in the eastern USA, from Minnesota (primarily in the south-east) east to southern Ontario and New York, and extending south-west to north-east Oklahoma and south-east to north-western Kentucky and West Virginia.
		Isolated breeding populations also exist in north-east Virginia and north-east North Carolina.
