40 1874. Ipswich Mass.—Passerculus princeps Nov 20th 1874, Nov.20 Rose at 5.30 and met Purdin at the Eastern R.R. Station for a trip together to Ipswich. Arrived at the town we took a boat and pulled down river for the sand hills about 8 miles at the water's flow. The morning was cloudy & cold with that gray look in the sky peculiar to Nov. days. A little below the village saw a Buteo Bonalis and an Archibuteus lappons and opposite Greenwoods a Colymbus Septentrionalis which was very shy during at our approach. Gulls also became very numerous here and then species were noted to L. marinus, argentatus and Lencopterus. The marinus were all immixt and we readily distinguished by the large size and the black bar on the tail which was quite conspicuous. The attend a scream which bore a faint resemblance to the cry of Buteo lineatus and chased the herking gulls whereupon the latter was so fortunate as to pick up any food. We approached within at least 80 yds. of a large bird of gulls sitting on the sand nearer than I ever got to do many before. As we neared the mouth of the river Ereophilus counts became very abundant. Many were in flocks of 20 or 30 and fed both on the marsh and along the beach where the tide had receded. But few lit on the sand hills. In general appearance habits and motions they strikingly resemble the sandpipers. Their notes are very like those of Arcturus luteus.
