LC
Peregrine Falcon Falco peregrinus

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). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely 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.

Population justification
The global population is estimated to number c.1,200,000 individuals (Rich et al. 2004), while population estimates include: c.100-100,000 breeding pairs and c.50-10,000 wintering individuals in China; < c.100 breeding pairs, c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in Taiwan; c.100-10,000 breeding pairs in Korea; c.100-10,000 breeding pairs in Japan and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).

Trend justification
The overall trend is likely to be stable. This species has undergone a large and statistically significant increase over the last 40 years in North America (2600% increase over 40 years, equating to a 127% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). Note, however, that these surveys cover less than 50% of the species's range in North America.

Conservation Actions Underway
The tree-nesting population in central and eastern Europe declined from c. 4,000 pairs to extirpation, before restoration efforts in Germany and Poland returned it to c. 20 pairs. Significant further efforts are needed to fully restore it across its former range, which included Germany, Poland, Russia, Belarus and the Baltic States (European Peregrine Falcon Working Group in litt. 2007).
