Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Aves Passeriformes Cisticolidae

Scientific Name: Prinia cinereocapilla
Species Authority: Hodgson, 1854
Common Name(s):
English Grey-crowned Prinia
Identification information: 11 cm. Small prinia with dark blueish-grey crown and narrow rufous-buff supercilium. Rufescent upperparts and buffish underparts. Similar spp. Breeding Rufescent Prinia P. rufescens has less sharply defined crown, narrower supercilium, less strongly rufous upperparts and whiter underparts. Non-breeding Ashy Prinia P. socialis is larger and longer-tailed and lacks supercilium behind eye. Voice Song is forced cheeeeeeeesum-zip-zip-zip. Also, rapidly-repeated zip notes.

Red List Category & Criteria: Vulnerable A2c+3c+4c ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

This species is suspected to be rapidly declining as a result of the degradation and conversion of wooded grasslands throughout its range. It therefore qualifies as Vulnerable.

Previously published Red List assessments:
2008 Vulnerable (VU)
2004 Vulnerable (VU)
2000 Vulnerable (VU)
1994 Lower Risk/near threatened (LR/nt)
1988 Lower Risk/least concern (LR/lc)

Geographic Range [top]

Range Description: Prinia cinereocapilla has been recorded in the terai of Uttar Pradesh, West Bengal and Assam, India (BirdLife International 2001), and was recently also found at Sukhna, along the Haryana-Punjab state border (Singh 2006) and at Pangot, Nanital and Dehradun in Uttarakhand (Sondhi 2011, A. P. Singh in litt. 2012). In Nepal, it formerly occurred from Kanchanpur district in the west to Ilam district in the east, but it has declined and is now confined to three protected areas: Chitwan National Park, and in adjoining areas of Parsa Wildlife Reserve and Bardia National Park and buffer zone (H. Baral in litt. 2012). Baral (2001) found it fairly common in Chitwan National Park and in adjoining areas of Parsa Wildlife Reserve. The Nepalese population is currently estimated at between 950-2,375 individuals (H. Baral in litt. 2012). It is also known locally from Bhutan, where it is considered rare.

Population [top]

Population: The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend Justification:  Rapid habitat degradation is continuing across the species's range, and this species's precise habitat requirements suggest that it is likely to be declining at a similarly rapid rate.
Current Population Trend: Decreasing
Additional data:
Number of mature individuals: 6000-15000 Continuing decline of mature individuals: Yes
Extreme fluctuations: No Population severely fragmented: No
No. of subpopulations: 2-100 Continuing decline in subpopulations: Yes
Extreme fluctuations in subpopulations: No All individuals in one subpopulation: No
No. of individuals in largest subpopulation: 1-89

Habitat and Ecology [top]

Habitat and Ecology: It primarily inhabits grassland with scrubby undergrowth, scattered trees and shrubs, particularly grasslands dominated by Themeda species, which typically occur close to Sal forests (Baral 2002). It also occurs in open forest and secondary growth, being more arboreal than other species of its genus. It is presumably resident from the lowlands up to 1,350 m, apparently breeding around June, although no confirmed nest has been reported.

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 3.8
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): The key threat is the loss of shrubby grasslands and open forests in the terai through conversion to agriculture, collection of fuelwood, overgrazing of livestock, and burning and harvesting of grass for thatch. As it seems to occur naturally at low densities throughout much of its range the deleterious effects of habitat fragmentation may be more pronounced. In Chitwan National Park it is threatened by the invasive alien Mikania micrantha which can smother grasslands (H. Baral in litt. 2012).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
There are recent records from Corbett Tiger Reserve, India, Chitwan and Parsa Wildlife Reserves, Nepal and Manas National Park, Bhutan.

Conservation Actions Proposed
Monitor populations in suitable habitat throughout the species's range to establish population trends. Survey areas of suitable habitat in intervening areas between known sites in order to clarify the distribution and population size. Extend, upgrade and link existing protected areas to conserve remaining tracts of suitable habitat. Control livestock-grazing, degradation of forest and encroachment in protected areas. Conduct widespread conservation awareness initiatives focusing on sustainable management of grassland and forest in and around protected areas.
