Justification of Red List category
The species is inferred to be declining at a rapid rate based on two independent sources; a significant decline in densities recorded from targeted surveys conducted in 2004-5 and 2017-18; and declining abundance indices from citizen science data collected throughout the range. The cause of these reductions are unclear. As such, Malabar Grey Hornbill is assessed as Vulnerable under Criterion A2bc + A3bc + A4bc.
