Table 1. Saker Falcon population estimates by country.

*Data quality scores for the population estimates are based on the following criteria:
A = excellent, quantitative data available with precision estimates based on comprehensive survey work;
B = good, quantitative data available, based on extensive field work;
C = medium, quantitative data available, based on limited field work;
D = poor; no quantitative data available and limited field surveys;
E = No data, guess.

The above table illustrates that in most countries where the Saker Falcon breeds there are no good, quantitative population estimates. This is particularly true for countries across Central Asia, where the vast majority of the world’s Saker Falcons breed.
