observed to-day, except perhaps the sandpipers, could be distinguished by their cry. Aegialus semipalmatus. Quite a few. Pelidna alpina. Quite a few. Black-bellied. Ereunetes pusillus. Hundreds. All the small pipers shot, with the exception of one were of this species. On the flats of San Leandro Bay and Chelrose slough there were myriads of sand- pipers this morning, probably both this and the next species. Once in a while a large swarm of them would arise and wheel about in the air, showing first one white there dark as they swing. Limonites minutilla. Only one taken, was with Ereunetes pusillus when shot. Macrochamphus griseus. Common, but not as many as a week ago, all red. Two calls. Limosa fedoa. About a dozen. Symphemia semipalmata. About a dozen. Numenius hudsonicus. Very common, feeding mostly on the marsh. Usually where a flock is feeding, there will be lookout posts, who gives his noisy warning at the approach of Man. They have at least two calls, one a call of warning, consisting of several notes in quick succession, and then often when a flock is flying high. The other is sort of a long purring call given as a flock settles to the marsh.
