Justification:
|
Lonchura flaviprymna is found in open riparian woodland of the eastern Kimberley Region, Western Australia and north-west Northern Territory, Australia. Information regarding changes in its range in the Kimberley Region is contradictory, with speculation that it may have contracted, or expanded from arid areas towards the coast. There is no evidence for either scenario, and abundance has not apparently changed. Hybridisation and competition with Chestnut-breasted Mannikin L. castaneothorax have been mooted as threats, but the species remains common in the agricultural areas around Kununurra with little evidence of intermediate forms. Degradation of habitat by stock has also been suggested as a threat, particularly along rivers, but the effects of degradation have not been translated into declines in range (Garnett and Crowley 2000). Recent reports suggest that slashing and spraying of weeds and long grass along tracks and irrigation channels where the species was common may have cause local declines, for example in Kununurra (I. Rudd in litt. 2003), but there is no evidence to suggest that such trends are more widespread. This species has an estimated global extent of occurrence of 20,000–50,000 km². The global population size has not been quantified, but the species is not believed to approach the thresholds for the population size criterion of the IUCN Red List (i.e., less than 10,000 mature individuals in conjunction with appropriate decline rates and subpopulation qualifiers), even though the species is described as 'uncommon' in at least parts of its range (Clement 1999). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.

Lonchura flaviprymna is found in open riparian woodland of the eastern Kimberley Region, Western Australia and north-west Northern Territory, Australia. This species has an estimated global Extent of Occurrence of 20,000-50,000 km. Information regarding changes in its range in the Kimberley Region is contradictory, with speculation that it may have contracted, or expanded from arid areas towards the coast. There is no evidence for either scenario, and abundance has not apparently changed. The global population size has not been quantified, but the species is not believed to approach the thresholds for the population size criterion of the IUCN Red List (i.e. less than 10,000 mature individuals in conjunction with appropriate decline rates and subpopulation qualifiers), even though the species is described as 'uncommon' in at least parts of its range (Clement 1999).

Therefore, although global population trends have not been quantified, the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
