Entire List of Water=Birds Observed. 
This list comprises the notes of both trips to the islands, the 
first from March 26 until April 4, and the second from May 11 until 
June 9. It includes all the water-birds positively identified from the 
time we left San Pedro until our return. A few others were seen, 
such as ducks and waders, which were not with certainty identifiable. 
1. Lunda cirrhata —Tufted Puffin. 
About a dozen of these birds were probably breeding on Santa 
Barbara Island. They were seen flying about a bluff on the 
north side of that island on several occasions during our stay 
there—May 13 to 18. They were shy and none were obtained. 
2. Ptychoramphus aleuticus —Cassin’s Auklet. 
This bird was breeding in large numbers on Santa Barbara 
Island. The southwest side of the mesa from the top of the 
bluff to the summit of the hill was crowded with their bur¬ 
rows. On the evening of May 16, Mr. Gaylord and I went 
over to this colony. Not a single bird was to be seen above 
ground during the day, nor even until quite dark; but by 8 
o’clock the Auklets began one by one to arrive from out to sea. 
They would alight among the weeds with a thud and shuffle 
through the stalks in a very uncertain manner, but each one 
seemed to know where his respective burrow was. When leav¬ 
ing, they generally had a hard time to gain their flight, flopping 
among the weeds in a most awkward way. We caught quite 
a number besides digging out several. The gullets of those 
arriving were distended with a quantity of partly digested fish 
for feeding the young. Out of eleven occupied burrows dug 
into, four contained each a badly incubated egg with the old 
f 
bird, and the other burrows young of various sizes. The bur¬ 
rows were two to four feet long with an eliptical nest cavity at 
the end, four inches in diameter. Nineteen specimens of the 
Cassin’s Auklet were preserved.
