Population justification: Based on nest-counts, Donald et al. (2012) estimate a global population of at least 9,000 breeding pairs, however, as active nests typically have several nest-helpers there may also be a significant additional non-breeding population. It is placed here in the band 10,000-19,999 mature individuals, but may well prove to be larger. |
|
Trend justification: Encounter rates in the Yavello Wildlife Sanctuary declined by 80% between 1989 and 2003 (Borghesio and Giannetti 2005), which covers a large part of the species's range, and declines are presumed to be continuing, owing to on-going habitat conversion and degradation. The overall rate of decline is estimated to be very rapid. More recent studies suggest that the species's population in fact may be stable (P. Donald in litt. 2012), however a rapid ongoing decline is retained here until this can be confirmed. |
