Paler and less heavily-streaked than the other thrushes breeding in North America, the Veery (6 ½ - 7 ½ inches) is most easily identified by its tawny-colored back and head. Other field marks include pink legs, white breast, and dark eye lacking any noticeable eye-ring. Male and female Veerys are similar to one another in all seasons. The Veery breeds across southern Canada and the northern U.S. Smaller populations occur at higher elevations in the Rockies and the Appalachians south to New Mexico and Georgia, respectively. This species is a long-distance migrant, breeding in southeastern Brazil. In summer, Veerys breed in wet deciduous forests. On migration, this species may be found in the undergrowth of various kinds of forests across North America. Little is known about the Veery’s habitat preferences in winter due to the relative inaccessibility of its winter range, but all records for this species at that time of year come from dense tropical forests. Veerys eat fruits, berries, and insects during the breeding season; fruits are presumed to make up a large part of this species’ diet on winter grounds. The vast majority of North American birders, including many scientists, never see the Veery in its winter range. This species is much easier to observe in summer and on migration, although it is more often heard than seen due to its preference for habitats with thick vegetation. Veerys may be observed foraging food while hopping along the forest floor or through the branches of trees. Males may be located by listening for their unique, onomatopoeic song. The Veery is most active during the day, but, like many migratory songbirds, this species migrates at night.
Veeries (Catharus fuscens) are medium-sized thrushes with a body shape similar to that of an American Robin. Overall, they have a plump body and rounded head with a straight, narrow bill (Cornell Lab of Ornithology, 2015). Typical length from bill to tail tip is 7 inches while average wingspan is 12 inches. Veeries have reddish-brown upperparts, a thin pale eye ring, a faintly streaked buff throat and upper breast, light underparts, gray flanks and face patch, and pinkish legs (McCormac and Kennedy, 2004). Veeries express regional differences that may complicate the process of identification. In Newfoundland and the far-western portion of their range (British Columbia, Alberta, Oregon, Montana, and Idaho), Veery populations have darker upperparts and more pronounced breast spotting, which may make them appear more like a Swainson’s Thrush or Gray-cheeked Thrush (Cornell Lab of Ornithology, 2015).
Overall, Veeries are easier to identify than other thrushes in their genus (Catharus) due to their reddish-brown upperparts. However, Veeries can be mistaken for similar species including: Hermit Thrush (Catharus guttatus), Wood Thrush (Hylocichla mustelina), Gray-cheeked Thrush (Catharus minimus), Swainson’s Thrush (Catharus ustulatus) and Brown Thrasher (Toxostoma rufum). In comparison to Veeries, Hermit Thrushes have a warm reddish-brown tail, lighter brown back and perform habitual tail bobbing. Wood Thrushes express more pronounced spotting on the chest and belly; they also tend to be plumper than Veeries. Gray-cheeked Thrushes are grayer overall and lack the warm reddish brown color of the Veery. Because of their gray color, Gray-cheeked Thrushes are more readily differentiated from Veeries, however, identification can be difficult in some portions of Veery range. Swainson’s Thrushes tend to be more olive brown in color with more pronounced chest spots and a spectacle-like, buff-colored eye ring. Brown Thrashers are larger with a longer, more curved bill and tail. Compared to Veeries, Brown Thrashers also exhibit yellow eyes and darker streaking on the chest and belly (Cornell Lab of Ornithology, 2015).
Veeries tend to behave in an inconspicuous manner; however, males are often the exception, emitting a beautifully complex song for which the species is named (Cornell Lab of Ornithology, 2015). Male Veeries emit a cascading resonant song of da-vee-ur, vee-ur, vee-ur, veer veer. The song itself is rather complex, exhibiting a wide range of frequencies, patterns and phrases. Despite these variations, the standard Veery song has two main parts: 1) an ascending introductory note and 2) a series of descending similar phrases (Samuel, 1972). Belinsky et al. (2015) found that male Veeries tend to modulate their song in aggressive contexts, specifically while protecting territory from other males. Modulations include the elimination of the ascending introductory note and the addition of airy, high frequency calls often referred to as “whisper calls” (Belinksky et al., 2015).
Veeries, like many thrushes, chorus at dawn and dusk (Belinksy et al., 2012). When compared to the dusk chorus, Belinsky et al. (2012) found that dawn chorusing Veeries experience increased interspecies acoustic competition. In their investigation, Veeries were often covered up by three species (Wood Thrush, Gray Catbird and Ovenbird) whose vocalizations share similar frequencies. Based on these findings, Belinsky et al. (2012) hypothesized that Veery dusk choruses evolved in response to acoustic competition. That is, in order to increase communication efficacy, it appears Veeries evolved to chorus at both dawn and dusk (Belinsky et al., 2012).
Veery foraging behavior mirrors that of other thrushes. Individuals can be found foraging on the ground or in low vegetation for insects, invertebrates and fruit. Veeries tend to search for hidden prey by lifting and flipping leaves with their beaks (Cornell Lab of Ornithology, 2015; Kaufman, 2014). Individuals may watch for prey from a low perch prior to dropping to the ground to forage or capture insects through short spurts of flight (Kaufman, 2014).
During the breeding season, Veeries favor dense understory thickets containing low leafy vegetation. Preferred sites are typically in close proximity to water (Kaufman, 2014). As ground nesting birds, Veeries rarely place nests higher than five feet above ground. Female Veeries are the primary nest constructors (Kaufman, 2014), building mostly cup-shaped structures. Nests are typically constructed with grapevine bark, weed stems, and wet decomposed leaves. These structures are often built on top of herbaceous vegetation or tucked into brush and debris against fallen logs (Cornell Lab of Ornithology, 2015). The diameter of a Veery nest ranges from 3 to 6 inches. Nest height also exhibits variation, typically ranging between 3.5 to 5.5 inches (Cornell Lab of Ornithology, 2015).
Male Veeries initiate the breeding season by arriving first at breeding grounds. Upon reaching adequate habitat, males claim their territory prior to the arrival of the females. During this time, males are territorial with each other as well as exhibiting aggression toward arriving females. Males will display such aggressive behavior for about 3 to 4 days before transitioning into courtship displays. During courtship, male Veeries display a distinct combat dance among rival males by raising and snapping their bills, quivering their feet, freezing in an erect pose, and flickering their wings and tail (Cornell Lab of Ornithology, 2015).
The typical clutch size for a Veery is quite low at 1 to 5 eggs with females producing 1 to 2 broods a year. The incubation period lasts about 10 to 14 days and is then followed by a 10 to 20 nesting day period. Veery eggs are typically greenish blue in color and may rarely display brown spotting (Cornell Lab of Ornithology, 2015). Female Veeries primarily take on the responsibility of brooding after they have laid. Following hatching, feeding nestlings is a responsibility shared by both parents (Kaufman, 2014).
During the breeding season, Veeries occupy moist, dense, deciduous forests of North America (Kaufman, 2014; Heckscher, 2011). In the southern parts of their breeding range, Veeries inhabit cooler microclimates. These cool microclimates are most commonly located at high elevations on north-facing slopes and in wet depressions (Burleigh, 1927). The Veery is a Neotropical migrant, and travels to South America where it takes up winter residence. While in their wintering grounds, it is typical to find Veeries in the undergrowth of lowland tropical forests (Kaufman, 2014). In 2001, Remsen hypothesized that the Veery’s winter range surrounds two separate areas in Brazil. More specifically, Remsen (2001) suggests that the winter range of the Veery is very large and includes tropical South America east of the Andes and also parts of Central America. The results of such investigations suggest that the winter range of the Veery is so extensive that it may encompass some of the largest wilderness areas remaining on the planet today, including portions of western Amazonia and surrounding regions (Remsen, 2001).
Heckscher et al. (2011) found that two of five geo-tracked Veeries displayed inconsistent movement when compared with that of traditional migratory behavior. Such inconsistent behavior included the arrival at wintering grounds and then subsequent movement to another region of suitable habitat. The second movement was referred to as a “second winter.” It was hypothesized following this discovery that the Veeries migrated in such a manner because of seasonal flooding of lowland forests in Amazonia. These data therefore suggest that Veeries are possibly intolerant of flooded or swamp-like habitat.
While foraging, Veeries are usually located in habitats containing shrubs in hardwood forest understories and midstories (Paszkowski, 1984). In forests located in the southeastern portion of New York, Veeries frequently build nests in exotic shrubs such as Japanese Barberry (Berberis thunbergii) (Schmidt et al., 2005). Such results indicate that Veeries can be rather tolerant of invasive plant species. Overall, habitat preferences investigated by Bertin (1977) indicate that in mature woodlands containing Veery, understory cover and proximity to running water may be less important than mesic habitats, therefore suggesting that moisture content may be a factor driving such preferences.
Paler and less heavily-streaked than the other thrushes breeding in North America, the Veery (6 ½ - 7 ½ inches) is most easily identified by its tawny-colored back and head. Other field marks include pink legs, white breast, and dark eye lacking any noticeable eye-ring. Male and female Veerys are similar to one another in all seasons. The Veery breeds across southern Canada and the northern U.S. Smaller populations occur at higher elevations in the Rockies and the Appalachians south to New Mexico and Georgia, respectively.

Die Wilson-Drossel (Catharus fuscescens) oder Weidenmusendrossel ist eine Vogelart aus der Familie der Drosseln (Turdidae).
Die 16–18 cm lange Wilson-Drossel ist auf der Oberseite hellbraun und auf der Unterseite weiß gefärbt. Auf der hellbraunen Brust befinden sich dunkle Flecken. Die Beine sind rosafarben und der Augenring nur schwach ausgeprägt.
Der Vogel brütet in feuchten Laubwäldern im südlichen Kanada und in den nördlichen USA und überwintert im östlichen Südamerika. In Westeuropa taucht er selten als Irrgast auf. In Teilen seines ursprünglichen Verbreitungsgebietes wurde er von der Walddrossel verdrängt.
Die Wilson-Drossel sucht am Boden unter dem Laub Insekten und fängt diese auch manchmal im Flug. Daneben gehören auch Beeren zur Nahrung. Forschungen des Ornithologen Christopher Heckscher in Delaware deuten darauf hin, dass die Dauer der Brutzeit der Wilson-Drossel mit der Intensität der kommenden Hurrikansaison negativ korreliert.
Der Vogel baut ein Schalennest am Boden oder in Bodennähe in einem Busch. Als Opfer von Brutparasitismus werden ihm vom Braunkopf-Kuhstärling Eier untergeschoben.

The veery (Catharus fuscescens) is a small North American thrush species, a member of a group of closely related and similar species in the genus Catharus, also including the gray-cheeked thrush (C. minimus), Bicknell's thrush (C. bicknelli), Swainson's thrush (C. ustulatus), and hermit thrush (C. guttatus).[2][3] Alternate names for this species include Wilson's thrush (named so after Alexander Wilson[4]) and tawny thrush.[5] Up to six subspecies exist, which are grouped into the eastern veery (C. fuscescens fuscescens), the western veery or willow thrush (C. fuscescens salicicolus), and the Newfoundland veery (C. fuscescens fuliginosus).[6]
The specific name fuscescens is Neo-Latin for "blackish", from Latin fuscus, "dark".[7] The English name may imitate the call.[8]
This species measures 16–19.5 cm (6.3–7.7 in) in length. Its mass is 26–39 g (0.92–1.38 oz), exceptionally up to 54 g (1.9 oz). The wingspan averages 28.5 cm (11.2 in).[9] Each wing measures 8.9–10.4 cm (3.5–4.1 in), the bill measures 1.2–1.9 cm (0.47–0.75 in) and the tarsus is 2.7–3.25 cm (1.06–1.28 in).[10] The veery shows the characteristic under-wing stripe of Catharus thrushes. Adults are mainly light brown on the upperparts. The underparts are white; the breast is light tawny with faint brownish spots. Veeries have pink legs and a poorly defined eye ring. Birds in the eastern portions of the species' breeding range are more cinnamon on the upper parts; western birds are more olive-brown. In the east, the veery is distinguished easily by its coloration; distinguishing western veeries from other Catharus thrushes is more difficult.[11]
This bird has a breezy, downward-spiraling, flute-like song, often given from a low and concealed perch. The most common call is a harsh, descending vee-er, which gave the bird its name. Other calls include a chuckle, a sharp and low "wuck", and a slow wee-u.[12] Veeries have been shown to decrease the rate and duration of singing when exposed to barred owl playback, possibly to decrease the chance of predation.[13]
The breeding habitat is humid deciduous forest across southern Canada and the northern United States. Breeding habitat includes dense growth and dense understory close to a water source, such as a stream.[14] These birds migrate to eastern South America. It has been found that winter range may include the entire Amazon basin, Mérida state in Venezuela, the headwaters of the Orinoco River, and São Paulo state, Brazil.[15] Stopover regions during migration of several veeries from Delaware include the coast of the Gulf of Mexico, the coasts of the Carolinas, Cuba, Jamaica, Colombia, and Venezuela.[15] They are very rare vagrants to western Europe.
They forage on the forest floor, flipping leaves to uncover insects; they may fly up to catch insects in flight. They mainly eat insects and berries. Insects are a main food source during the breeding season, while fruit and berries may compose most of the diet during the late summer and fall.[14]
They make a cup nest on the ground or near the base of a shrub. The nest consists of three structural layers, including outer, inner, and nest lining layers.[16] The outer layer consists of leaves and supporting branches, while the inner layer consists of material woven together.[16] Nest lining consists of flexible material such as bark, roots, and seeds.[16] The use of different parts of 27 plant species, including invasive/alien plants, has been documented.[16] Nests contain three to five greenish-blue eggs that may or may not have brown spots.[14] The eggs are incubated for 10 to 14 days by the female, while both parents feed nestlings.[14] Young Veeries can leave the nest between 10 and 12 days after they hatch.[14]
This bird has been displaced in some parts of its range by the related wood thrush (Hylocichla mustelina). However, a case of interspecific parental care of a veery nest by a wood thrush has been documented in which a wood thrush provided more parental care to the veery nestlings than did the parents, possibly due to sexual solicitation by the female veery.[17] Veeries are occasional hosts for the eggs of brown-headed cowbirds (Molothrus ater). Veery males have been found to engage in behaviors similar to the polygynandrous Bicknell's thrush in that males may feed nestlings at more than one nest and there may be multiple male feeders at nests.[18][19]
Threats to the veery include nest parasitism by brown-headed cowbirds, climate change, and alteration of Amazonian lowland forests.[14][15] It is suggested that veeries are in decline, and breeding bird survey trend results indicate that veery populations declined across most of its range from 1966 to 2013.[14][20] There have been concerns that the use of invasive/alien plant parts may decrease nesting success, but negative impacts have not been documented.[16] Other potential threats include the loss of woodland habitat, squirrels, chipmunks, and raptors.[21]

Viitarastas (Catharus fuscescens) on pienikokoinen rastas, joka kuuluu varpuslintuihin. Lajin nimesi James Francis Stephens 1817.
Linnun pituus on 17–19 cm ja paino 28–54 g. Viitarastas muistuttaa pienikokoista laulurastasta, mutta sen mahapuoli on pääosin yksivärisen valkea ilman mustia täpliä. Kurkussa ja rinnan sivuilla on punaruskeaa täplitystä. Koiraan laulu on kaunista ja se laulaa parhaiten hämärissä. Sukupuolet ovat samannäköisiä.
Lajista tunnteaan 2 alalajia, tummempi nimialalaji C. r. fuscescens (Stephens, 1817), C. r. salicicola (Ridgway, 1882) ja epäselvä C. r. fuliginosa.
Viitarastas pesii laajalla alueella Kanadan eteläosassa sekä Yhdysvaltain luoteisosassa. Se on muuttolintu, joka talvehtii Etelä-Amerikassa, pääasiassa Keski- ja Etelä-Brasiliassa. Laji on lievästi taantunut pesimäalueellaan. Se on hyvin harvinaisena tavattu myös Euroopassa, ei kuitenkaan Suomessa.

Multimedia w Wikimedia Commons Drozdek brunatny[4] (Catharus fuscescens) – gatunek krępego ptaka z rodziny drozdowatych (Turdidae). Upierzeniem przypomina słowika szarego. Bardzo rzadko zalatuje do Europy z Ameryki Północnej.
Posiada charakterystyczną dla rodzaju Catharus dużą głowę, ale różni się mniejszą ilością kropkowania na piersi. Zasiedla wszelkie zadrzewienia, wydaje miękkie „wi-juu”. Długość ciała 17–19 cm[5], masa ciała 25–43 g[5], rozpiętość skrzydeł wynosi 29-30 cm.
Wyróżniono kilka podgatunków C. fuscescens[6][2]:

Rostskogstrast[2] (Catharus fuscescens) är en liten nordamerikansk art inom familjen trastar.[3]
Rostskogstrasten är en liten trast (16-18 centimeter)[4] som har det karaktäristiska vit-svart-vita undersidan på vingarna som är typiskt för Catharus-trastar. De vuxna fåglarna är huvudsakligen bruna upptill. Undertill är de vita; bröstet är ljusbrunt med mörka fläckar. De har rosa ben, ringen runt ögonen är svår att uppfatta. Fåglar i öst är mer kanelfärgade på överkroppen, västliga fåglar är mer olivbruna.

Rostskogstrasten häckar i fuktig lövskog i södra Kanada och norra USA och flyttar vintertid till Sydamerika. Den delas in i fyra underarter med följande utbredning:[3]
Rostskogstrasten är en mycket sällsynt gäst i Europa med endast 13 fynd fram till och med 2015. Alla utom två har gjorts i Storbritannien, ett i Azorerna och ett i Sverige när en individ ringmärktes 26 september 1978 på Svenska Högarna längst ut i Stockholms skärgård.[5]
Fåglarna bygger sina fågelbon på marken, nära basen på en buske. De äter föda på skogsmarken, vänder blad för att hitta insekter; de kan ibland flyga upp för att fånga insekter i luften. Rostskogstrastar är omnivorer och äter huvudsakligen bär och insekter.
Arten har ett stort utbredningsområde och en stor population, men tros minska i antal, dock inte tillräckligt kraftigt för att den ska betraktas som hotad.[1] IUCN kategoriserar därför arten som livskraftig (LC).[1]
