- Do not disturb: the life rafts keeping pelicans afloat January 17, 2018One watchful, grey eye appears behind a shroud of silvery-white wing feathers that conceal a massive orange beak and leathery pouch. The pelican barely keeps its eyelids open after hours spent hunting fish on the lake, but then two play-fighting chicks clumsily step close to the edge of the floating nest platform and one’s mother […]
- Five years' success for African mountain hotspot - bring on phase two! January 10, 2018Rocky mountain peaks push up out of a lush green carpet of forest, shaded by scuttling clouds. Many of these mountains were born from fire, breaking into the world as volcanoes, but now their appearance couldn’t be more tranquil. This is the Eastern Afromontane Hotspot, a site of incredible importance for over 10,000 species of […]

Great Bustard, Otis tarda, is currently listed as Vulnerable under criteria A2cd+3cd+4cd (see BirdLife International 2017) as it is undergoing rapid population declines. It has a wide, but fragmented distribution across Eurasia, with a small, declining population present in Morocco. … Continue reading

Concern has recently been expressed over this species’s status, as there is evidence that it is declining in abundance (per Hofmeyr 2012). Following recent research, it has been recommended that the species be classified as Vulnerable because of past and probable future decreases in its population and because of its susceptibility to on-going land conversion, climate change and possibly increased predation (Hofmeyr 2012).

BirdLife species factsheet for Kori Bustard Kori Bustard Ardeotis kori has an extensive African range. It is thought to be experiencing range-wide decline (Collar et al. 1986, Collar 1996), owing to ongoing habitat destruction and unsustainable levels of hunting (del Hoyo et … Continue reading
Archived 2012-2013 topics: Arabian Bustard (Ardeotis arabs) and Nubian Bustard (Neotis nuba): request for information
Vehicle-based transect surveys for raptors in the Sahel zone of Mali and Niger in 2004 failed to record any bustard species, despite both A. arabs and N. nuba being frequently recorded along the same transects in 1971 and 1973 (Thiollay 2006). Additional information on these species is requested, in particular on the severity of threats and likely population trends throughout their ranges. Continue reading

Archived 2011-2012 topics: Little Bustard (Tetrax tetrax): what are the trends in Russia and Central Asia?
The Little Bustard Tetrax tetrax has a Palaearctic distribution and two geographically separated breeding populations: the western (found in the EU); and eastern (breeding in western and central Asia). It is currently classified as Near Threatened under criterion A on the IUCN Red List, because it is suspected to have undergone a moderately rapid global population decline approaching 30% over three generations. If the global population is suspected to be undergoing an overall decline at a rate of 30-49% in 30 years, the global status of Little Bustard would need to be revised to Vulnerable. To re-evaluate its status, more data are needed about the size and trends of populations in the east, particularly from Russia and Central Asia. Continue reading
A survey conducted in August 2010 (coinciding with a peak in male displays) in north-western India (Gujarat, Rajasthan and Madhya Pradesh) (Bhardwaj et al. 2011), which followed methodology comparable to that of a survey in 1999 (Sankaran 2000), recorded a decline of 65% in the sightings of S. indicus. Information on recent population trends is requested from other parts of the species’s range to help in the assessment of the overall rate of decline. Continue reading
Although BirdLife International does not yet have the capacity to assess global extinction risk at the subspecies level, we are currently working on a project to produce a synthesis of all bird taxa, at the species and subspecies level, that are known or thought to have gone extinct since 1500. This is the first time that subspecies extinctions have been systematically documented and analysed, and we hope that the results will provide new insights to support global efforts (including through the BirdLife Partnership) to conserve the world’s threatened birds.
