Bird species accumulation according to the pooled transect-mapping (MTW) data of transects AWACl, AWAC3, and AWAC4; (a) number of species versus study time, and (b) number of species versus number of'birds recorded'. Bird species accumulation. - Species accumulation for the two transects at the Carolina ridge was very similar, with graphs flattening out after about 30- 35 h of surveying or 2000-2500 'birds recorded' (Fig. la,b). By contrast, at AWACl species accumulation continued for about 50 h or 3500 'birds recorded', reflecting the higher species richness and abundance of the lowland transect. It should be emphasized that the 26% higher species richness at AWACl, in com- parison with AWAC3 and AWAC4, was not the result of the 14% higher survey effort at the former tran- sect, because only two () additional species were 175.
