Royal Flycatcher

From Wikipedia, the free encyclopedia.
The Royal Flycatchers are birds in the genus Onychorhynchus in the Tityridae family. Depending on authority, it includes a single widespread, or four more localized species. The specific epithet of the type species, coronatus, and the common name of all the species in this genus, Royal Flycatcher, refer to the striking, colourful crest, which is seen displayed very rarely, except after mating, while preening, in courtship as well as being handled.






Taxonomy

Amazonian Royal Flycatcher (Onychorhynchus (coronatus) coronatus).

The Amazonian Royal Flycatcher (Onychorhynchus coronatus coronatus) is a passerine bird of the tyrant flycatcher family. Depending on authority, it is often considered the nominate subspecies of the single widespread Royal Flycatcher, or considered a species closely related to 3 other Royal Flycatchers, the Northern Royal Flycatcher, the Pacific Royal Flycatcher, and the Atlantic Royal Flycatcher.
The Amazonian Royal Flycatcher is found in forest and woodland throughout most of the Amazon basin in northern Bolivia, eastern Peru, easternEcuador, eastern Colombia, Venezuela, the Guianas, and northern and western Brazil. It is easily overlooked and typically found in low densities, but overall it remains widespread and common. It is therefore considered to be of Least Concern by BirdLife International.

Northern Royal Flycatcher (Onychorhynchus (coronatus) mexicanus).

The Northern Royal Flycatcher (Onychorhynchus coronatus mexicanus) is a bird in the Tyrannidae family. It is often considered a subspecies of O. coronatus.
It is found in Mexico, south through most of Central America, to north-western Colombia and far western Venezuela. Its natural habitat is subtropical or tropical moist lowland forests.

Description

The Northern Royal Flycatcher is 16.5–18 cm (6½-7") long, brown above small buffy spots on its wing-coverts; the rump and tail are tawny-ochraceous in colour. The bill is long and broad.
The Northern Royal Flycatcher has an erectile fan-shaped crest, coloured red in the male and yellow-orange in the female. The display with the crest fully raised is seen extremely rarely, except during banding sessions.
The Northern Royal Flycatcher is usually inconspicuous and quiet, but sometimes gives a repeated sharp clear pree-o or key-up, sounding rather like aManacus manakin or a jacamar.

Pacific Royal Flycatcher (Onychorhynchus (coronatus) mexicanus).

The Pacific Royal Flycatcher (Onychorhynchus coronatus occidentalis) is a species of bird in the Tyrannidae family. It is often considered asubspecies of Onychorhynchus coronatus. It is found in relatively dry forest and woodland in western Ecuador and far north-western Peru. It is threatened by habitat loss.

Population justification: The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: This species is suspected to be declining rapidly, as a consequence of extremely high rates of habitat loss within its range (Ridgely and Greenfield 2001).

Atlantic Royal Flycatcher (Onychorhynchus (coronatus) mexicanus).

The Atlantic Royal Flycatcher (Onychorhynchus coronatus swainsoni) is a bird in the Tyrannidae family. It is often considered a subspecies ofOnychorhynchus coronatus.
The Atlantic Royal Flycatcher is endemic to Atlantic forest in south-eastern Brazil.
It is threatened by habitat loss.

Justification
This species has recently been discovered at a number of new locations; however its range is still small and severely fragmented by ongoing extensive habitat loss, and the small population is likely to be declining rapidly. It consequently qualifies as Vulnerable.

Taxonomic note
Onychorhynchus coronatus (Sibley and Monroe 1990, 1993) has been split into O. coronatus, O. occidentalis, O. mexicanus and O. swainsoni following Stotz et al. (1996) contra SACC (2005), pending the outcome of investigation into the taxonomy of this group by SACC.
Identification
16-16.5 cm. Large-billed flycatcher, with spectacular, but rarely seen, crest. Largely uniform dull brown upperparts with pale, bright cinnamon rump and tail. Whitish throat, with rest of underparts ochraceous buff and no breast markings. Striking crest is usually left flat, imparting hammerhead shape to head, but when raised is remarkable combination of scarlet, black and blue (yellow replaces red in female). Voice Clear pree-o, reminiscent of a jacamar or manakin.

 Distribution and population
Onychorhynchus swainsoni is confined to the dwindling forests of east Brazil (Minas Gerais, Rio de Janeiro, São Paulo, Paraná, Santa Catarina and possibly an old record from Goiás), where it was very poorly known. It has not been recorded in the Serra dos Órgãos (Rio de Janeiro) at least since 1940’s (Mallet-Rodrigues et al. 2007). However, there have been recent records from at least seven new sites in Paraná (Mitroszewski et al. 2004; Mikchi and Bernils 2004) and four new sites in São Paulo (F. Olmos in litt. 2004; L. F. Silveira in litt. 2004; Buzzetti 2000), with the spread of records suggesting a fairly continuous extent of occurrence along the Atlantic forest belt in eastern São Paulo and Paraná, from the border with Rio de Janeiro to at least Guaratuba bay, and inland to the Ribeira valley and Paranapiacaba and Mantiqueira ranges (F. Olmos in litt. 2004). In Santa Catarina state it was known only historically until 2006 when one was seen at Volta Velha (Mallet-Rodrigues et al. 2006). A report of its occurrence in south-east Paraguay (Graves (1990) is erroneous (M. S. Foster in litt. 2000). Three areas are particularly important: near Estacão Vera Cruz, south Bahia, Itatiaia National Park, Rio de Janeiro/Minas Gerais, and a number of sites in the Serra do Mar, São Paulo. 

Population justification
The population is estimated to number 1,000-2,499 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

Trend justification
This species is suspected to be declining rapidly, in line with rates habitat loss within its range.

Ecology
It inhabits the understorey of lowland and lower montane Atlantic forest where it often perches motionless for long periods. At Intervales State Park, it is found most frequently in the proximity of small watercourses (L. F. Silveira in litt. 2000). The diet appears to be insectivorous. It sometimes joins mixed-species flocks and has been noted associating with foliage-gleaners (R. S. R. Williams verbally 1998) and fire-eyes (G. M. Kirwan in litt. 1999). A juvenile has been seen in January in Rio de Janeiro, suggesting breeding in the austral spring. At Intervales State Park nest-building was recorded during October, and two eggs were laid in November (A. C. De Luca in litt. 2007; Kirwan 2009). 

Threats
The widespread clearance, degradation and fragmentation of the Atlantic forest are the principal threats to this naturally rare tyrannid. 

Conservation Actions Underway
It is known from several protected areas, including: Monte Pascoal (G. M. Kirwan in litt. 1999), Itatiaia and Serra da Bocaina (J. M. Goerck verbally 2000) National Parks, Intervales State Park (L. F. Silveira in litt. 2000), Ubatuba Experimental Station (A. Whittaker in litt. 2000), the Guaricana Forest Reserves (Guaratuba and Morretes) (F. Costa Straube in litt. 2000), Salto Morato private reserve (Guaraqueçaba) (Mikchi and Bernils 2004), Pico do Marumbi State Park (Mikchi and Bernils 2004), Saint Hilaire-Lange National Park (Mikchi and Bernils 2004), Fazenda Monte Alegre private reserve, and a private reserve at Piquete (F. Olmos in litt. 2004). Conservation Actions Proposed
Survey remaining suitable habitat within its known range to clarify distribution and status. Study its ecological requirements, with Itatiaia National Park perhaps a suitable locality. Increase the area of suitable that has protected status.
