5 thoughts on “Flores Hawk-eagle (Nisaetus floris)”
The wide-ranging survey to estimate population size is still ongoing. This species often conflicts with communities as it tends to be opportunistic in hunting domestic chickens around residential areas. The estimated territory size of 40 km2 suggested by Gjershaug et al. (2004) appears to be less accurate. A study on movement patterns indicates a home range of 8.4 km to 23.08 km2 by Kuspriyangga et al. (unpublished). The small population size is attributed to limited reproductive capacity. In 2023, there was one recorded hatchling in Flores and two hatchlings in Sumbawa. Each pair only produces 1 hatchling every 2 years.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested in commenting. The window for consultation is now closed and we are unable to accept any more comments until 12 February 2024. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List status on this page on 12 February 2024, when discussions will re-open.
We are grateful to the comment made by O. Hidayat, and this information has now been incorporated into a revised assessment. Notably, if the home range is smaller than the 40km2 used for the calculation of population size, it is possible that the population size is larger than originally supposed. To reflect this, the upper bound has been increased to 1,500. Based on available information, our preliminary proposal for the 2024 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 18 February 2024, after which the recommended categorisations will be put forward to IUCN.
The final 2024 Red List categories will be published on the BirdLife and IUCN websites in December 2024, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Flores Hawk-eagle is recommended to be listed as Endangered under Criterion C2a(ii).
Many thanks for everyone who contributed to the 2024.1 GTB Forum process. The final 2024 Red List categories will now be published on the BirdLife and IUCN websites in October 2024, following further checking of information relevant to the assessments by both BirdLife and IUCN.
