The rufescent tiger heron is found in wetlands from Central America through much of South America. It generally occurs below , though it has been recorded as high as in Colombia.
|
|
The female is olive brown above and buff below with a light eye-ring and rufescent rump. The breast and flanks are buffy. Young birds are dark brown with buff spots.
|
|
Although the rufescent tiger heron's population size and trend has not been quantified, its range is huge, so the International Union for the Conservation of Nature lists it as a species of least concern.
|
|
The bushbird is 16.5 cm (6.5 inches) long and unmistakable. The male is slate gray, the female rufescent brown. It inhabits well-developed secondary growth at 150–1750 m. It is insectivorous and a bamboo specialist.

The rufescent prinia (Prinia rufescens) is a species of bird in the family Cisticolidae. It is found in Southeast Asia, the Indian subcontinent (mainly in the northeast) and southern Yunnan. Its natural habitat is subtropical or tropical dry forest.
|
|
The adult rufescent tiger heron is relatively easy to distinguish from fasciated and bare-throated tiger herons, as it is rufous (rather than primarily gray) on the head and neck. Young birds, however, are much more difficult to identify.
|
|
Tigrisoma is a genus of herons in the family Ardeidae. The genus was erected by the English naturalist William Swainson in 1827, with the rufescent tiger heron (Tigrisoma lineatum) as the type species. The genus name combines the Ancient Greek tigris, meaning "tiger" and somā, meaning "body".

|
The rufescent imperial pigeon (Ducula chalconota), also known as the shining imperial pigeon, is a species of bird in the family Columbidae. It is found in montane forests of New Guinea. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
|
|
The male rufescent imperial pigeon is long, and the female is long. It weighs about . In the subspecies smaragdina, the head is slaty-grey. The back and wing coverts are metallic green, with bronzy and bluish reflections, and the flight feathers are darker and more bluish.
|
|
In Kenya and Uganda, the subspecies is sometimes known as the Elgon francolin. Compared to the nominate subspecies of Ethiopia, the Elgon francolin is brighter (more rufescent) and lacks black spots to the throat, leading to conflicting taxonomic treatments.McGowan, P. J. K. (1994). Moorland Francolin (Francolinus elgonensis).
|
|
The rufescent imperial pigeon is found singly, sometimes in pairs. It often sits in the middle layers of the forest, and it does not leave the forest. Usually silent, it hums slowly and mournfully and also gives a low hoo and a hollow knock. Duetting has been observed.
|
|
It has a short tail and heavy bill; it is drab olive-brown with bright rusty lower flanks and vent, a greyish-white throat and breast and variable pale grey supercilium and lores. Juvenile birds have dark rufescent- brown crowns and upperparts. The calls are distinctive. The subspecies M. a.

Cuban Kite is a little smaller than the Hook-billed Kite. Males have upper- parts gray, the tail barred with black; underparts evenly barred grayish and white. Females resemble the Grenada form of the Hook-billed Kite, but brown barrings on the underparts less rufescent; bill larger (also deeply hooked) and mostly yellowish.
|
|
The rufescent darkeye (Tephrozosterops stalkeri), also known as the bicoloured white-eye, is a species of bird in the family Zosteropidae. It is monotypic within the genus Tephrozosterops. It is endemic to the island of Seram in Indonesia. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

Zakerana rufescens (common names: Malabar wart frog, reddish burrowing frog, or rufescent burrowing frog) is a species of frog that is endemic to the Western Ghats, India. It occurs in Maharashtra, Karnataka, Goa, and Kerala states. It is a locally common species associated with riparian and forest edge habitats in open and lightly degraded tropical moist semi-evergreen forests.
|
|
In addition, it varies from brown, hazel-brown, dull chestnut-brown, and occasionally lilac-brown, although it darkens as it ages. At times, the surface develops orange-brown, rufescent areas. The context is thick, very firm, white, and slowly turns vinaceous when cut or bruised. The odor is that of a typical mushroom, although it tastes mild.

|
The male of the subspecies aspersiventer of the Andes in north- western Bolivia and adjacent Peru approaches melanochrous in colour, but has dense white barring to the belly. male Thamnophilus c. melanochrous. Females are equally variable. In most of this species range, their wings are blackish- brown with rufescent edging to the remiges, and white or buff wing-bars (often appears rather spotty).
|
|
The recurvebills are two species of Furnariid birds from the genus Syndactyla. They are restricted to humid forests in the South American countries of Bolivia, Peru and Brazil. Their common name refers to the peculiar bill-shape, which, at least in the case of the larger-billed Peruvian recurvebill, is an adaption for manipulating bamboo stems. Both species are overall rufescent brown.
|
|
The tail is graduated as in other prinias and the grey feathers are tipped in white. In the breeding plumage the upperparts are grey while non-breeding birds are pale above with rufous wings and a weak supercilium. It is found in scrub, forest clearings and other open but well vegetated habitats. It can be confused with the rufescent prinia.
|
|
The eastern screech owl (and its western counterpart) are actually some of the heaviest screech owls, the largest tropical screech owls do not exceed them in average or maximal weight, but (due to the eastern screech owls' relatively short tails) they are surpassed in length by Balsas (M. seductus), long-tufted (M. sanctaecatarinae), white-throated (M. albogularis), and rufescent owls (M.

As might be expected of a species that spends most of its time by the water, much of the rufescent tiger heron's diet is aquatic-based, including fish, crustaceans, water beetles and dragonfly larvae. It also takes adult dragonflies and grasshoppers. It typically hunts alone, standing hunched in shallow pools or wet areas of forest while it waits for prey.
|
|
The streaking is usually blackish, dusky brown, or sometimes rufescent- (reddish-) brown. The head is fairly large (although not especially so for a species in Strix) and rounded with no ear tufts.Owls of the World: A Photographic Guide by Mikkola, H. Firefly Books (2012), Holt, D.W., Berkley, R., Deppe, C., Enríquez Rocha, P., Petersen, J.L., Rangel Salazar, J.L., Segars, K.P., Wood, K.L. & Marks, J.S. (2019). Typical Owls.

Morchella palazonii is a species of morel found in Spain. Morels are edible mushrooms in the family Morchellaceae (Ascomycota). Morchella palazonii was described as new to science in 2015 by Philippe Clowez and colleagues, from collections under holly oak (Quercus ilex) and narrow-leafed ash trees (Fraxinus angustifolia) in Spain. This edible species is characterised by an elongated cap, a rufescent fruiting body, and small spores.

The rufescent tiger heron is a medium-sized heron, measuring in length, with a mass between . The sexes are similarly plumaged. The adult's head, neck and chest are dark rufous, with a white stripe down the center of the foreneck. The remainder of its upperparts are brownish with fine black vermiculations, its belly and vent are buffy-brown, and its flanks are barred black and white.
|
|
The fruit bodies are often rufescent and high. The conical cap is high and wide at the widest point. The cap surface features pits and ridges, which are formed from the intersection of 16–22 primary vertical ridges and few shorter, secondary vertical ridges, with frequent, sunken, horizontal ridges. The cap is attached to the stipe with a distinct sinus about 2–4 mm deep and 2–4 mm wide.
|
|
It is primarily slate grey, rather than truly black as its name would imply. The upperparts of an adult black tinamou are a uniform grey, while its midsection and greater wing coverts are sometimes edged with brown. Its lower breasts and flanks are a sooty brown color, as well as its belly. It has a rufescent vent, which may or may not have black speckling, depending on the subspecies.
|
|
It is also easily recognizable due to its broad and elongated black eye-mask. The mantle, back and underparts from the lower breast down are rufescent, contrasting with the white head, throat and upper chest and fading into darker olive-brown on the tail and upper wings. The nape is light gray. Females look almost identical to males but have a smaller crest, duller mantle, and slightly more pronounced gray on the nape.
|
|
The subspecies in the southern Western Ghats bourdilloni has a duller sooty-black hood, browner underside and the upper parts are more olive. The nominate form found north of the Palghat Gap has the hood dark black. In Sri Lanka, the subspecies siccata is found in the lower elevation while nigrifrons is found in the wet zone. The former has more olive on the upperparts while the later is rufescent on the upperparts.

The fasciated tiger heron is typically found along fast-moving streams. The fasciated tiger heron is found primarily in foothills, along rocky, quickly- moving streams. Its range extends from Costa Rica through northwestern Argentina, southeastern Brazil, and Guyana; it has been recorded as a vagrant in Nicaragua. Although it occurs from sea level to , it is generally found at higher elevations than the rufescent tiger heron where the two species occur together.
|
|
Dry-season form: Upperside as in the wet-season form. Underside differs in the ocelli being indistinct or absent, and the subterminal and terminal dark lines on both forewing and hindwing absent or very faint; the terminal margins are broadly rufescent (reddish) brown, fading inwardly into lilacine, the oblique white bar on the forewing outwardly diffuse. Antennae, head, thorax and abdomen dark brown; the antennae ochraceous towards apex. At Coorg Wingspan: 51–60 mm.

The northern banana salamander (Bolitoglossa rufescens), also known as common dwarf salamander or rufescent salamander, is a species of salamander in the family Plethodontidae (lungless salamanders). It is found in the Atlantic slopes of Meso-America from San Luis Potosi, Veracruz, and northern Chiapas in Mexico continuing on to the southern part of Guatemala, Belize, and northern Honduras. However, its range south of Mexico is uncertain because the records may refer to other species.
|

Morchella tridentina (=Morchella frustrata) is also rufescent and very similar to M. rufobrunnea. It is found in mountainous forests and maquis and forms a marked sinus at the attachment of the cap with the stem, which is pure white. At maturity, it develops more or less parallel, ladderlike interconnecting ridges. Microscopically, it often has moniliform paraphyses with septa extending in the upper half and has more regularly cylindrical or clavate 'hairs' on the stem, up to 100 μm long.

Lanius cristatus lucionensis, the Philippine shrike; note the grey crown and white throat contrasting with the rufescent underside. Kolkata, India The brown shrike is a migratory species and ringing studies show that they have high fidelity to their wintering sites, often returning to the same locations each winter. They begin establishing wintering territories shortly after arrival and their loud chattering or rattling calls are distinctive. Birds that arrive early and establish territories appear to have an advantage over those that arrive later in the winter areas.
|
|
The throat and head are white, often with a large rufescent patch around each eye, and the underparts are orange-brown. Depending on mainland subspecies, the feet are blackish or reddish, and the distal two-thirds of the tail can be blackish or russet with an orange-brown or whitish ring at its base. The Taiwanese subspecies has a white head with a narrow or no clear eye-ring, all-dark rufous upperparts and tail (no pale patch on lower back or ring on tail), and all-white underparts.
|
|
The plumage is similar for both sexes, which in the nominate is warm brown on the upperparts, dark brown on the wings (tinged with chestnut on the flight feathers). The upper breast and throat are pinkish-cream with brown streaks on the throat. The flanks are similar to the upperparts but slightly buffy, and the belly is cream-buff merging into the breast. The crown and forehead is rufescent brown, with a pale grey iris and the bill is either slate grey or brown with a paler or yellow tip.

41: 65–74 Until 2009, it was usually included as a subspecies of the western mountain coati, but the eastern mountain coati is overall smaller, somewhat shorter-tailed on average, has markedly smaller teeth, a paler olive-brown pelage, and usually a dark mid-dorsal stripe on the back (versus more rufescent or blackish, and usually without a dark mid-dorsal stripe in the western mountain coati). When the two were combined, they were rated as Data Deficient by the IUCN, but following the split the eastern mountain coati is considered endangered.

The chestnut-breasted partridge (Arborophila mandellii) is a species of partridge endemic to the eastern Himalayas north of the Brahmaputra, and is known from Bhutan, West Bengal (Darjeeling only), Sikkim and Arunachal Pradesh, north-east India, Nepal Himalaya and south-east Tibet. It is a distinctive partridge with chestnut breast-band and grey belly. It is distinguished from the similar rufous-throated partridge A. rufogularis by more rufescent crown and head-sides, white gorget and entirely chestnut upper breast. The scientific name commemorates the Italian naturalist Louis Mandelli.

At in length and in weight, it is significantly smaller than the northern goshawk of Eurasia and North America, and somewhat smaller than the Cooper's hawk of North America, but among the largest Accipiter hawks in Central and South America (only the rare grey- bellied hawk is larger). As in other Accipiter hawks, the female is far larger than the male. Adults are grey above with darker wings and crown, and a banded tail. The underparts typically vary from dark grey to very pale grey, but the southern subspecies can sometimes be rufescent below.
|
|
Some of the palest birds are also washed out looking even on the body which can appear anywhere from cream-tawny to light grayish. It is thought that in some populations perhaps paleness increases with age, although it is possible that there is an historic genetic factor to such pale variations. On the contrary, some adults can also be a richer, more deeply dark brown (or somewhat rufescent) than average with perhaps a mild increase in average darkness of hue to the east of the species’ range. When many of the feathers are freshly molted, they can take on a slight purplish gloss.

This species is very similar to Morchella rufobrunnea, another rufescent, cosmopolitan species with pale colours, which is nonetheless found in urban and suburban areas. The latter is distinguished by an adnate cap lacking a sinus and a distinct dark pruinescence on the stem, more pronounced in young fruit bodies. Due to its similar light coloration, M. tridentina may also be confused with Morchella esculentoides; as Kuo states, "it looks like a black morel with the colors of a yellow morel." The vertically arranged pits and ridges, as well as the slight indentation where the cap meets the stem on M. tridentina, however, more closely resemble the black morels such as M. elata.

Until 2009, the western mountain coati (then simply known as the mountain coati) usually included the eastern mountain coati as a subspecies, but that species is overall smaller, somewhat shorter-tailed on average, has markedly smaller teeth, a paler olive-brown pelage, and usually a dark mid-dorsal stripe on the back (versus more rufescent or blackish, and usually without a dark mid-dorsal stripe in the western mountain coati). When the two were combined, they were rated as Data Deficient by the IUCN, but following the split the western mountain coati is considered Near Threatened. There are two subspecies of the western mountain coati: N. o. olivacea and the slightly smaller and darker N. o.

Externally, the two species of mountain coatis are quite similar, but the eastern mountain coati is overall smaller, somewhat shorter-tailed on average, has markedly smaller teeth, a paler olive- brown pelage, and usually a dark mid-dorsal stripe on the back (versus more rufescent or blackish, and usually without a dark mid-dorsal stripe in the western mountain coati). Both are found in cloud forest and páramo; at altitudes of for the eastern mountain coati, and for the western mountain coati. A population discovered in southern Peru (more than south of the previous distribution limit) has tentatively been identified as the western mountain coati, but may represent an undescribed taxon.Pacheco, V., R. Cadenillas, E. Salas, C. Tello, and H. Zeballos (2009).
