BirdLife species factsheet for Bornean Crested Fireback
Bornean Crested Fireback (Lophura ignita) occurs on Borneo and on Bangka Island off southeastern Sumatra. It is a lowland forest specialist, which is found at elevations of up to 1,000 m (Madge and McGowan 2002, del Hoyo et al. 2020). The species tolerates a certain level of habitat degradation, as it has also been recorded in logged forest and remnant forest fragments (D. L. Yong in litt. 2014, del Hoyo et al. 2020).
Bornean Crested Fireback is threatened by habitat loss. Forest destruction in the Sundaic lowlands of Indonesia and Malaysia has been extensive because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber, and forest fires. Population declines caused by habitat loss are compounded by trapping for the cage-bird trade, as the species is facing a high pressure from hunting (Symes et al. 2018).
Bornean Crested Fireback is currently listed as Near Threatened, approaching the threshold for listing as threatened under Criterion A2cd+3cd+4cd (BirdLife International 2020). However, new information regarding the population trend suggests that the species may warrant a change in Red List status. Therefore, it will be re-assessed against all criteria:
Criterion A – Bornean Crested Fireback is undergoing a rapid decline caused by habitat loss and hunting. A study investigating the combined impact of these threats found that habitat within the range has been lost at a rate of 11.3% over 15 years (Symes et al. 2018; see also Tracewski et al. 2016). As the species appears to readily tolerate logged forest (del Hoyo et al. 2020), habitat loss alone may not cause severe population declines. The species is facing high hunting pressure, which accounts for additional declines of 57.9% over the same period, so that the population would overall be declining at a rate of up to 69.2% over 15 years (Symes et al. 2018). Following a thorough reassessment, one generation length is now thought to be 6.6 years for this species (see Bird et al. 2020)*. Hence, the relevant timeframe for an assessment against Criterion A is 19.8 years. A population decline of up to 69.2% over 15 years equates to a decline of up to 78.8% over 19.8 years. We can assume that declines are continuing at the same rate into the future. The species thus meets the threshold for listing as Endangered under Criterion A2cd+3cd+4cd.
Criterion B – The Extent of Occurrence (EOO) for this species is 1,000,000 km2. This is too large to warrant a listing as threatened under Criterion B1, and therefore the species may be considered Least Concern under this criterion. The Area of Occupancy (AOO) has not been quantified according to IUCN guidelines (see IUCN Standards and Petitions Committee 2019), and thus the species cannot be assessed against Criterion B2.
Criterion C – We have no information on the population size and structure; therefore, we cannot fully assess the species against Criterion C.
Criterion D – The population size has not been quantified, and hence the species cannot be assessed against Criterion D1. The distribution range is too large to justify a listing as threatened under Criterion D2.
Criterion E – To the best of our knowledge no quantitative analysis of extinction risk has been conducted for this species. Therefore, it cannot be assessed against this criterion.
Therefore, it is suggested that Bornean Crested Fireback (Lophura ignita) be listed as Endangered under Criterion A2cd+3cd+4cd. We welcome any comments on the proposed listing and specifically request up-to-date information on the population size and structure.
Please note that this topic is not designed to be a general discussion about the ecology of the species, rather a discussion of its Red List status. Therefore, please make sure your comments are relevant to the discussion outlined in the topic. By submitting a comment, you confirm that you agree to the Comment Policy.
*Bird generation lengths are estimated using the methodology of Bird et al. (2020), as applied to parameter values updated for use in each IUCN Red List for birds reassessment cycle. Values used for the current assessment are available on request. We encourage people to contact us with additional or improved values for the following parameters; adult survival (true survival accounting for dispersal derived from an apparently stable population); mean age at first breeding; and maximum longevity (i.e. the biological maximum, hence values from captive individuals are acceptable).
