Louisiana Waterthrush Habitat Model go to: USFWS Gulf of Maine Watershed Habitat Analysis go to: Species Table. It is likely that the Canadian population is supported by immigration from U.S. populations (COSEWIC 2006). Additionally, any potential northward expansion that might occur because of warming temperatures may be negated by decreased availability of water, to which the health of Louisiana Waterthrush populations is so intrinsically tied. Peck and James (1987) documented nest parasitism of breeding Louisiana Waterthrushes by Brown-headed Cowbirds (Molothrus ater) at a rate of 25% in Ontario, but with only a sample of eight nests. In Canada, the birds only breed in the Niagara region of Southern Ontario and along Lake Erie, and occasionally along the southern shield in Ontario into southwestern Quebec. uses" (Johns), so it was not surprising that occurrences were too infrequent They act as filters to pollutants that run off the land from farms, towns and cities. Dendroica Environnement et Faune. 2008.

We examined conditions at 7 BBS occurrence sites within the study water; secondary habitat is characterized by mature, deciduous swamp forest http://birds.cornell.edu/bfl/speciesaccts/louwat.html; Proc. The Louisiana Waterthrush walks with a characteristic bobbing movement that distinguishes it from its counterpart, the Northern Waterthrush. Territories for both swamp- and stream-nesting pairs are estimated to be about 2 ha in area (COSEWIC 2006), with the estimate for the latter based on the territory length average (400 m) from a northern New York study (Eaton 1958) and an estimated 50 m territory width. Wildlife with specialized habitat needs that overlap forested areas undergoing shale gas development may be the most vulnerable to disturbance, which made the waterthrush an ideal organism to assess potential demographic consequences from shale gas development. 44p. For streams that support Louisiana Waterthrushes, it is recommended that 75% of the stream length is maintained in a naturally-vegetated state, with a riparian buffer of at least 100 metres wide (Ontario Partners in Flight 2008). * Ontario Partners in Flight forest guild priority species (Ontario Partners in Flight 2008). 410-411 pp. Centre for Land and Water Stewardship. Habitat Louisiana Waterthrushes breed along clear, perennial streams in mature deciduous or mixed forest, usually in hilly environments. Comparative ecology of Louisiana and Northern Waterthrushes. As the small Canadian population of Louisiana Waterthrush occurs at the northern part of its continental range, and the vast majority of its continental breeding distribution and population occurs further south in the United States, it is important to note that population changes at the continental level may have a significant effect on management of this species in Canada. Migration routes are poorly understood, although sightings and specimen collections suggest that migration occurs through the southeastern United States, with many migrants flying across the Gulf of Mexico and some following the Central American coast (COSEWIC 2006, Mattsson et al. document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
is also taken from leaves, stems of plants, leaf litter, soil and moss. Rationale:The species’ Canadian range has historically been restricted to southern Ontario due to suitable habitat availability and climatic factors (COSEWIC 2006). Cornell Univ. 2006. Sign in to see your badges. //]]>
2009). The Louisiana Waterthrush is also sensitive to flash-flooding caused by development within watersheds (Ontario Partners in Flight 2008). There are difficulties in determining accurate population estimates or trends for Louisiana Waterthrush in Canada. surfaces (roads, parking lots, etc.). Every five years, success of this management plan implementation will be measured against the following performance indicator: Bent, A.C. 1953. Press, Ithaca, New York. You will not receive a reply. Waterthrush are nicknamed the “feathered trout” since they feed primarily on aquatic insect prey and share many sensitivities to environmental impacts as trout. Brown-headed Cowbird populations are also controlled on its breeding grounds. Confirmed nesting location of Louisiana Waterthrush in Quebec. Cited in COSEWIC . of Ornithology). Figure 2.
Kerr, S.J. Size: Wing length averages 7.8-8.5 cm and weight averages 20 g. Assess and monitor population sizes, trends, and distribution for all Canadian populations. comm.) The eggs are incubated for 12-14 days, and then, ten days after hatching, the young leave the nest. A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers. The Louisiana waterthrush has a plain brown back and white underparts streaked with black. Frequency – Indicates whether the threat is a one-time occurrence, seasonal (either because the species is migratory or the threat only occurs at certain times of the year), continuous (on-going), recurrent (reoccurs from time to time but not on an annual or seasonal basis), or unknown.

Identification Guide to North American Birds, Part 1. However while many species are known for their beautiful breeding plumage colors, they are also known to bird watchers as being extremely challenging to identify when in the fall they revert to their drab tan, olive, and pale colored plumages.

USDA Technical Report NE-108. This species is of high conservation importance, because of its relatively small breeding range, low overall density, and dependence on clear forest streams both on its breeding and tropical wintering grounds. In A. Poole and F. Gill, (eds.) Latin name: Parkesia motacilla The Prothonotary Warbler: Population viability and critical habitat in southern Ontario, Canada.

After accounting for environmental factors, shale gas development also had negative effects on nest survival and reproductive success. Headwater streams and wetlands of high water quality and well developed This study indicated that it does not take much disturbance in the ecosystem to affect wildlife demography and reproductive success. Listen +3 more audio recordings. Nests are cup-shaped and made of mud, leaves, pine needles and twigs. Ontario Partners in Flight. They migrate at night through the south-eastern U.S. and Mexico following the Mississippi flyway towards their wintering grounds in Central and northern South America and the West Indies (Curson et al. A life history study of the Louisiana Waterthrush. Breeding Birds of Ontario Nidiology and Distribution, Volume 2: Passerines. Robbins, C.S. In early spring, sooner than many other bird migrations, the Louisiana Waterthrush celebrates its arrival with a clear ringing call.
