LC
Eurasian Thick-knee Burhinus oedicnemus

Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Distribution and population
This species has a large global population estimated to be 140,000-330,000 individuals (Wetlands International 2002). The status of the European population (46,000-78,000 pairs, occupying 25-49% of the global breeding range) was recently reassessed, and following a large decline in Europe during 1970-1990 (Tucker and Heath 1994), the species continued to decline during 1990-2000, when up to 20% of birds were lost and several national extinctions occurred. Overall, declines in Europe exceeded 30% over three generations (27 years) (BirdLife International 2004). However, there is no evidence of declines elsewhere in its global range, and incomplete data from Central Asia and southern Russia suggests that there the species is stable or increasing in places (A. Mischenko in litt. 2005).

Population justification
It has a large global population estimated to number 130,000-310,000 individuals. The European population is estimated at 46,000-78,000 pairs.

Trend justification
The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006), and in Europe, trends since 1996 show that populations have undergone a moderate increase (p<0.05), based on provisional data for 21 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands; P. Vorisek in litt. 2008).
