Colidius pusillus 4 July Neacole River Coal Mine, 15°25'W, 78°29'N, Alboray after flying off before I could get within 70-80 feet of this. The only ones seen beyond South Creek in the afternoon were over along one of the larger lakes where there was considerable cane wash, now nearly dry. None seen feeding. 5 July Birds still abundant on the flats opposite north dune, where 30-40 birds seen and 8 cooed with little effect. When I arrived there were two small groups, which occasionally joined, of 3 and 5 birds which danced over a wide area and occasionally came singing persistently. Birds were seen feeding along the river (2) and at the timberland edge of the willows in rather open Euphorbia flats (4-5). There was not much feeding activity on the 1st beach level, where I got most of the birds last time, but some activity apparently along the ponds just inland of this, where I was never actually able to see birds feeding. Several birds were seen feeding on the 2nd beach level, a Cornicularia - Ectavia flat, where they chased about actively for insects. None seen in the larger lakes, but occasionally flushed them from the Ceres marshes. At the Sea part of the area most activity was in the empty Ceres pools just inland of the willows on the river, and along the river, where 2-3 birds seen. 2 or 3 seen along the river in the evening and none on the
