Louisiana Waterthrush Photo Gallery

So instead I thought through my observations again.

Winters in Mexico, Central America, and the Caribbean. Although its common name suggests that it is a southern bird, the Louisiana Waterthrush actually breeds throughout the eastern United States, as far north as southern Maine. A bird of forest streams, the Louisiana Waterthrush looks like a thrush or sparrow; however, the bird is a warbler.

However, LOWA populations are on the rise within our specific region, making the Tennessee River Gorge an area of regional importance. They both have similar loud chip notes, but their songs are distinctive. The presence of running water is apparently strongly preferred. The song consists of 2 to 4 clear loud ringing down-slurred notes, ending with a complex jumbled of phrases that trail off at the end. I was flabbergasted. The bird was totally comfortable and actually came within my minimum focusing distance several times. ​ Nesting Facts Clutch Size: Roberts, however, assigned Surber’s observations to the Louisiana Waterthrush ( ).

What is a Louisiana Waterthrush?

Breeding season Their breeding season occurs from April to June. Status in Tennessee: Hertzel and Janssen ( ) later added Fillmore and Washington Counties to the list. All three species walk on the ground, rather than hop.

For convenience we banded all males with the numbered band on their right leg and a combination of two color bands on their left leg. Different shades of yellow and olive occur in many species, including the dull, brown, streaked plumages of females and immatures. Pennsylvania demonstrated that waterthrush territory densities were lower and that laying dates were advanced along streams impacted by acid mine drainage, compared to circumneutral streams Mulvihill (1999, 2020). Though it looks more like a small thrush or a sparrow than a warbler, its constant tail bobbing and loud ringing song make it an easy bird to identify. SCIENTIFIC NAME:

Did the birds’ legs almost glow “hot pink? Indeed, a large number of reports came from just two localities: After around 16 days, young can fly and after an additional 7 days, they can feed themselves. If it contained nestlings, we had a good chance to catch the female parent, and also the male, if he had not been caught using song playback earlier in the season.

  • In summer 2020, the American Ornithologists' Union changed the genus of Louisiana Waterthrush from Seiurus to Parkesia.
  • See also Appendix H.


Historically occurring in the southeastern United States, this little known species is thought to have been dependent upon canebrakes on its breeding and wintering grounds in Cuba. Avoids high elevations (DeGraaf and Rudis 1986). Mud, often collected from the stream bed, holds the outer portion of the nest together. With this research project we have helped to better address threats to LOWA and their habitat – whether they be local or global! These include areas where the species could most likely be expected to persist, areas where it might be able colonize with future climate change, and areas where the species might experience a loss of suitable habitat.

  • This record stood alone for nearly 80 years, and the 1980s closed with but one additional occurrence, so a pulse of eight birds in the state during the 1990s, followed by four more during 2020 alone, could hardly have been more surprising.
  • They resemble spot-breasted thrushes (e.)
  • The supercilium is thicker in Louisiana than in ​Northern, and tends to flare at the rear.
  • Since LOWA often return to the same summer breeding grounds year after year, we are able to successfully and safely recapture LOWA as they return from their southern wintering grounds.
  • While not always present, it is virtually diagnostic when it is (visible in both photos).


That’s why their songs are so important. Young hatch in 12 to 14 days and fledge at around 10 days. I don’t know what this Louisiana Waterthrush is eating but I know that I am glad that I am not eating it.

Here I caught it at the top of a little bob, the Louisiana Waterthrush version of pushups. In winter in the tropics, they also prefer forested areas in and around water, even sometimes using coastal mangrove swamps. Ovenbirds have olive upperparts and a rusty crown stripe bordered with black; there is a bold white eye ring. Correct me if I am wrong, but I think this is a Louisiana Waterthrush. Additional information and photos added by Avianweb. Below they are whitish with distinct brown streaks on the breast and belly.


Chisago, Pine, Houston, Olmsted, and Winona. Over the course of less than four months we located a total of 16 territories, banded 26 adult birds, found and monitored 11 nests, and banded 35 nestlings. The bird life of Texas, University of Texas Press, Austin. The male's song is a musical, distinctive series of descending notes followed by a warble. The wood-warblers occur throughout North America except for the far northern tundra. Both parents feed the altricial chicks, and male appears to feed them more often than female. How to know if you have a yeast infection, fibroids can be surgically removed if necessary to preserve fertility. The study, partially funded this year by a grant from Pennsylvania's Wild Resource Conservation Fund, may eventually help with efforts to protect and restore forested headwaters throughout the region.

Brown-headed Cowbird populations are also controlled on its breeding grounds. The particular tracking device that TRGT and our partners used is called a light-level geolocator. Forests smaller than 350 ha had a 50% smaller probability of occurrence than those 3,000 ha or larger. Waterthrushes can be easily identified by their habit of bobbing their heads and moving their tails up and down as they walk. Most species of wood-warblers are long distance migrants to Central and South America. But the study will not end there. The species winters rarely or casually south to northern South America and north to the southern United States, including southeastern Arizona (Rosenberg 2020).

This meant I was going against the bird gurus at Cornell.

Identification guide to North American birds, part 1. The size of each nest appears to depend upon the size of the recess in which it sits. (7 cm) Incubation Period: Its breeding range is apparently expanding northward into such states as New York, Connecticut, Vermont and Michigan, most likely in response to the reforestation of areas that were extensively lumbered in the late 1800’s and early part of the 20th century. Louisiana warbler is a heavy-bodied warbler.

I wasn’t sure about that and besides don’t birds’ legs get muddy? And though Louisiana Waterthrush prefer habitat with clear, rushing streams next to which to nest, while they are on migration they are much less picky and can be found in a variety of wet habitats. REPRODUCTION : Incredible innovations have led to the creation of tracking units as small as a half of a gram (roughly the weight of a paperclip)! It is not colorful, being brownish above and white streaked with brown below. Telling them apart is another matter. The many species of this family have evolved to fill a wide variety of niches including marshes (yellowthroats) to tree trunks (the Black-and-white Warbler), and spruce forests (the Cape May Warbler). As a result almost all observations are of birds in breeding spots.

They fledged when they were just 10 days old and able to make only short, weak flights. Nesting and reproduction: This article is licensed under the GNU Free Documentation License. Datasets for each species that compare 2020 results to future scenarios for 2080. Well, the bird didn’t make a peep, not even once. Headwater streams and wetlands of high water quality and well developed pool and riffle complexes are important (Prosser and Brooks 1998)" (Brown et al. )"18 Mar 2020 – Which Waterthrush was that?

Heavily streaked light underparts contrast with pinkish sides.

Once the species reached the mouth of the St. Still, the earliest Northern Waterthrush date is March 14th. It primarily picks, or takes quick-jab-like strokes directly at food items, or at herbaceous plants, leaf litter soil, rocks and moss. (Wilson unpub.) In one case, a "bank" created by soil adhering to the roots of a wind-thrown tree near the stream was used. Vaginal yeast infections, in the study, the women used one pill a night for a week.

Focused studies of the Louisiana Waterthrush began with detailed natural history accounts of breeding individuals by Eaton ( Eaton, S. )Data collected by Pennsylvania's Department of Environmental Protection and the Loyalhanna Watershed Association show that it is very acidic (pH 4. )After experimenting with different net arrangements, we settled on placing one net upstream and one net downstream, each about 10 meters from the nest. George (2020) and Master et al. Workers also found 40 possible records. While not definitive, results obtained in 1996 point to a number of differences that may be related to acid pollution in Laurel Run. Again we took advantage of their innate territorial behavior.

Incubation by female only, 12-14 days. Together, these findings indicate that measures of Louisiana Waterthrush distribution and reproduction may be useful as indicators of stream ecosystem integrity. (2 cm) Egg Width:


For forest information call 304-558-3500 or visit www. Habitat, Natural History and Distribution. In life, I never saw the wings shoot out to help the bird keep its balance. You may wish to consult our Index of all nature topics covered since February 2020. This is an exciting time in the avian research world.

Insects, many arthropods, earthworms, aquatic insects, snails, and occasionally small frogs or fish. These geolocators map the LOWA's migration routes and wintering grounds by measuring ambient light levels in association with time of day. Less common and widespread today than it was two centuries ago, the Louisiana waterthrush's decline is mainly due to the reduction of suitable habitat, through clearing and channelization of streams, as well as pollution, and the impounding of rivers and streams to create reservoirs. Dendroica is abandoned because Setophaga is nested within it and has priority; Ergaticus is embedded within the clade occupied by Cardellina; Euthlypis is subsumed within Basileuterus; Oporornis is restricted to one species while its former congeners are removed to Geothlypis; Parula proves to be widely paraphyletic (two species move to Setophaga, the rest to a resurrected Oreothlypis); Phaeothlypis is indistinguishable from Myiothlypis; and the three Wilsonia are more correctly placed in Cardellina (two species) and Setophaga (one). A field guide to western birds’ nests. We measured and weighed each bird, recorded its breeding condition, and released it back into its territory within 10 minutes of its capture.

Nearly always found in and around aquatic habitats, primarily in forested environments. As a bird of forested streams, Lousiana Waterthrushes are sensitive to water pollution, forest fragmentation, and losses of habitat from infestations by introduced pests such as balsam wooly adelgid. This includes bottomland swamps and lagoons, riparian areas, and hilly brooks and streams. In many eastern states it is a species of conservation concern due to habitat loss. Modeling studies conducted by the University of Massachusetts project an increase (by nearly 25%) in the capability of the landscape of the Northeast to support this species by 20809. A tricky component of these geolocators is that they do not transmit any signal back to the researchers, but rather store the data until the device is returned. Many other times, however, we watched in frustration as males skillfully avoided flying into our net, or flew in only to bounce out again. Vaginal yeast infections, among AIDS patients, the prevalence of oral yeast infections is a bit higher, ranging from 9 to 31 percent of patients. Within the next few weeks, all the waterthrushes had begun their migration to distant neotropical wintering grounds, and our first field season was behind us.

Adult upperparts are brown, with a white eyebrow that extends well beyond the eye and flares out slightly on the neck. Accidentals have been recorded in Greenland and the Canary Islands (de Juana 2020). However, Massachusetts is located at the northern extent of the range of the Louisiana waterthrush. This is a key to sorting out the waterthrushes, because their habitat preferences are quite different. In our experience, the breast and belly of the Louisiana Waterthrush are also whiter, while the Northern Waterthrush in the Carolinas often has a yellowish cast in those areas, but there are geographical variations in this characteristic. A lot of the visual differences are relative, but here’s a rundown of things to look for (preferably in combination) to ID a silent bird: Climate projections for the Northeast indicate that higher temperatures and a longer growing season will result in increased evapotranspiration (the loss of water by evaporation from soil and transpiration from plants)6.
