Northern Waterthrush

Northern Waterthrush looks and behaves like a thrush, and its name suggests that it is a thrush (Family Turdidae). It is actually a New World Warbler (Family Parulidae). In Minnesota it nests exclusively in the Arrowhead region. It is a common migrant throughout the state in the spring and fall. It is found in thickets and at the edges of woodlands near swamps, bogs, lakes, and ponds, and in ravines. It feeds at the edges of standing water for insects, other aquatic invertebrates, and small fish. As it forages it frequently bobs its tail.

At 5″ to 6″ in length, Northern Waterthrush is a large for a warbler. It has a long body, long legs, and a wingspan of 9½″. The upper parts are olive brown. The throat is pale yellowish to buff and lightly streaked. The rest of the underparts pale yellowish to buff with heavy dark streaking. There is little contrast between the flanks and the rest of the underparts. On the head there is a dark eye line and a bold buff “eyebrow”. The eyebrow narrows to a point at the rear, and it ends on the head, not on the neck. On some individuals the eyebrow and the underparts are paler, almost white. The legs are pinkish.

Louisiana Waterthrush (Parkesia motacilla) eyebrow line is buff in front of the eye, white behind, and broad in back, not tapered. It continues back to the nape of the neck. The throat is white and unstreaked. The breast and belly are white. The flanks and undertail coverts are tinged buff.

This species was formerly included with the ovenbird in the genus Seiurus. Recent mitochondrial DNA studies suggest that the waterthrushes are not closely related to the ovenbird. The genus was split and the waterthrushes were placed in the new genus Parkesia.

I was following a Wood Duck down the river in the Minnesota River as I pulled over and noticed this small Northern Waterthrush along the bank foraging for food.
