Figure 5. Quality of population size estimates (number of populations and percentage of all populations) populations with no population size estimates Population size estimates are now available for 98% of the AEWA populations. Table 1 lists the remaining ten populations with no population estimates. Table 1. Populations with no size estimates Buff-spotted Flufftail NE Eastern & Southern Africa Sarothrura elegans elegans, Buff-spotted Flufftail S West Africa to Central Africa Sarothrura elegans reichenovi, Rail Western Siberia/South-west Asia Rallus aquaticus korejewi, African Rail Southern & Eastern Africa Rallus caerulescens, Eurasian Golden Plover Northern Siberia/Caspian & Asia Minor Pluvialis apricaria altifrons, Little Ringed Plover West & Asia/Eastern Africa Charadrius dubius curonicus, Eurasian Woodcock Western Siberia/South-west Asia (Caspian) Scolopax rusticola, Steppe Gull South-west Siberia/South-west Asia Larus fuscus barabensis, For these populations knowledge is lacking about their size for one or more of the following reasons: a) cryptic species, e.g. rails or snipes; b) difficult to separate from other species or populations in the field, e.g. Steppe Gull Larus fuscus from Heuglin’s Gull and other large white-headed gulls), barabensis L. f. heuglini c) they occur in the West Asia - East Africa flyway or Central & South-west Asian part of the Western Palearctic with low intensity monitoring both at the breeding and wintering grounds.
