Robinson. During the breeding season, favors steeper ravines with hemlocks and fast-moving water with lots of rocks to hop on. The Louisiana Waterthrush is estimated to occur in Canada over an areal extent of 35 500 km² (COSEWIC 2006). 2006. As one of the first neotropical migrants to arrive in Canada in April, the Louisiana Waterthrush probably relies on foraging in streams and the surrounding leaf litter for most of its diet until trees leaf out later in the spring, as has been observed elsewhere in its range (Craig 1984). Increased water levels in streams used by Louisiana Waterthrush would likely have negative effects on the reproductive productivity of the species by reducing the number of available nesting areas in flash-flood conditions or by depleting food resources through an increase in stream flow. Indigo Bunting--3 1998. Acknowledgment and thanks is given to all other parties that provided advice and input used to help inform the development of this management plan including various Aboriginal organizations and individuals, individual citizens, and stakeholders who provided input and/or participated in consultation meetings. Occurrence – Indicates whether the threat is historic (contributed to decline but no longer affecting the species), current (affecting the species now), imminent (is expected to affect the species very soon), anticipated (may affect the species in the future), or unknown. an interest in birds. Stays on the ground or in low vegetation, constantly bobbing its rear end up and down. Home » Learn » Bird Identification Guide » Warblers » Louisiana Waterthrush. Throughout most of the U.S., Northern Waterthrushes are seen only while they're migrating to their breeding grounds--primarily Alaska, Canada, New England, and the Great Lakes states. The Louisiana has a bold white eyebrow and plain unstreaked throat. It is an area-sensitive species that breeds in mature riparian forests of eastern North America and winters in similar habitat in Mexico south to northern South America and the Caribbean. Nest sites are found along stream banks, under mossy logs, and in roots of fallen trees (Prosser and Brooks 1998; Mattsson et al. Males and females are similar, and they do not change appearance seasonally. Inventaire de la Paruline hochequeue (Seiurus motacilla) en Outaouais, printemps et été 2005. and K.L. A Verified habitat suitability index for the Louisiana Waterthrush. pp. and Dendroica Environnement et Faune (2006, 2007). Houghton Mifflin Co.: New York, NY. (since 28 June 1982) It provides information on all the birds Blancherm, M.S.W. Whereas Louisiana Waterthrushes live along rushing streams, Northern is usually found around standing water. The results of the SEA are incorporated directly into the management plan itself, but are also summarized below in this statement. It inhabits clear, moving streams in rich, broad-leafed forests. Explore more birds threatened by climate change around the country. 05/02/99--after 4th year male 1995. 2007. 08/01/01--second year unknown Although the Louisiana Waterthrush supposedly breeds throughout the Carolinas, there are very few nesting records for the South Carolina Piedmont and almost none for the Coastal Plain. Data provided by Canadian Wildlife Service – Quebec (F. Shaffer pers. Bradstreet, G.S. iii + 18 pp. AOS - The American Ornitholgy Society is an international society devoted to advancing with a complete list of bird species, broken down per country, or in the example of the US or Canada, per state and province. A reduction in the amount of water available to aquatic invertebrates and insects that require water for part of their life cycle could compromise the food resources available to breeding pairs. While stream acidification has not been demonstrated to be a direct threat to populations in Canada, there is concern that a reduction of Louisiana Waterthrush populations in adjacent states due to stream acidification would be expected to reduce immigration from those areas.

Effects of stream acidification on the breeding biology of an obligate riparian songbird, the Louisiana Waterthrush (Seiurus motacilla), in: The effects of acidic deposition on aquatic ecosystems in Pennsylvania (W.
