Justification of Red List Category
This species has a highly restricted range, within which it is uncommon and local. It is therefore likely to have a moderately small global population size, which is likely to be declining owing to habitat loss. It is apparently tolerant of secondary and degraded habitats, suggesting that it is not at imminent risk, and it is therefore considered Near Threatened.
The population size of this species has not been quantified, but it is described as widespread and fairly common to common.
Slight declines are suspected to be occurring as a result of forest clearance within parts of the range.
Streptocitta albertinae occurs in the Sula (restricted to Taliabu and Mangole only) and Banggai Islands, Indonesia.
This species is found in tall trees in lowland forest and agricultural land up to 250 m. It appears to be more tolerant of degraded forest than Helmeted Myna Basilornis galeatus, but it is uncommon, occurs over a smaller area and has a narrower elevational range.
This species is likely to be affected by forest clearance and degradation as a result of logging activities and agricultural conversion. However, it is apparently tolerant of secondary and heavily degraded habitats, suggesting that declines are unlikely to be severe.
Conservation Actions Underway
Conservation Actions Proposed
Conduct repeated surveys within the range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, particularly tolerance of secondary habitats and response to fragmentation. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community-led multiple use areas.
