Made a trip thru 4 Rivers around noon today. Southeast of the Headquarters on the oneway road heading to the resevoir there was a ruddy turnstone with nearly 100 dunlins. There were also 2 black necked stilts in the same pool farther back away from the road. Also observed: 3 marbled godwits, one willet, several hundred black terns, least, Bairds, pectoral sandpipers.
