- How do we spread word about the biodiversity crisis? Experts weigh in. April 16, 2018How do we raise awareness about the biodiversity crisis facing the world? This was the problem put to six experts (including Sir David Attenborough) at a panel held at BirdLife’s Cambridge office, the Cambridge Conservation Initiative, on 12 April. It’s a tough one. Right now, species are going extinct at a rate up to 1,000 […]
- “The world has cause for optimism”: Sir David Attenborough’s keynote speech April 13, 2018Biodiversity loss is a huge problem for the conservation community. Not only are extinctions occurring at a rate up to 1,000 times normal levels, but public awareness about this crisis is lagging far behind that of other environmental issues such as climate change. It was precisely to address this problem that the Godfather of modern […]

This is […]

Tickell’s Brown Hornbill (Anorrhinus tickelli) is predominantly found in dense forest of southern Myanmar and adjacent Thailand up to 1,500m (Kemp and Boesman 2017). As with many hornbill species in this region deforestation and hunting may be leading to population … Continue reading
BirdLife is currently undertaking a review of the Red List status of forest dependent species following analyses of forest loss carried out by Tracewski et al. (2016) (see background forum topic here). A subset of Asian hornbill species come out … Continue reading
Species to be potentially uplisted after a reassessment of species against criterion A, following Tracewski et al. (2016)
This topic is open for comments on all species presented in the attached pdf. These species are; Grey-rumped Treeswift (Hemiprocne longipennis), Silver-rumped Spinetail (Rhaphidura leucopygialis), Barred Eagle-owl (Bubo sumatranus), Chaco Owl (Strix chacoensis), Wallace’s Hawk-eagle (Nisaetus nanus), Rufous-bellied Eagle (Lophotriorchis … Continue reading
This discussion was first published as part of the 2017 Red List update. At the time a decision regarding the status of several was pended, but to enable potential reassessment of these species as part of the 2018 Red List … Continue reading
Helmeted Hornbill (Rhinoplax vigil) (BirdLife species factsheet) is currently classified as Near Threatened as a result of a suspected moderate decline due to habitat loss and hunting pressure. The species occurs in primary semi-evergreen and evergreen lowland forest, up to … Continue reading

Archived 2011-2012 topics: Yellow-casqued Hornbill (Ceratogymna elata) and Brown-cheeked Hornbill (Bycanistes cylindricus): request for information
Recent observations suggest that both species are in rapid decline in Ghana. Data and observations are requested from other parts of these species’ ranges to confirm whether the situation in Ghana is representative of their overall status. Continue reading
Archived 2011-2012 topics: Oriental Pied Hornbill (Anthracoceros albirostris): request for information
Although little concern has been expressed in the past regarding its status, it was recently noted that this species has been almost completely extirpated from southern China (J. Fellowes in litt. 2010). In the Thai-Malay Peninsula, the species is in decline probably owing to off-take for the trade in fledglings and outright forest clearance, which leads to its local disappearance (Wells 1999). Continue reading
Archived 2011-2012 topics: Knobbed Hornbill (Aceros cassidix) and Sulawesi Hornbill (Penelopides exarhatus): uplist to Near Threatened?
Knobbed Hornbill Aceros cassidix and Sulawesi Hornbill Penelopides exarhatus are both currently listed as Least Concern. However, a recent reanalysis by Kinnaird and O’Brien (2007) has suggested that both species are declining at rates approaching 30% over ten years/ three generations based on recent and ongoing rates of habitat loss on Sulawesi. Comment and information relevant to the proposal to uplist these species would be welcome. Continue reading
