R. D. Hamilton 1966 Journal Cape Thompson 3 Aug. to be territorial. 4 Aug. After breakfast I took a trip to visit the Murre colony. The temperature was about 55° and the sky was partly cloudy. I walked along a gravel road to the top of the first hill to the north. I then walked along the top of that hill till I reached the SLC. I was unable to get a good look at the colony from there so I walked back till I could got in. The valley to the north at the hill. I then walked down that valley to the sea. I was able to get a good look at this location of the S and at the Murre colony. It seems that this is only a small part of the bird colony and the majority of birds are nesting on the cliffs, to the north. However they are nesting on the other side of where a cliff sticks out into the ocean so I went back up the valley, I long down on and went over the hill to the north and went down the next valley. From this location I could see the majority of the colony. The number of birds were quite big and I don't know how to estimate them. Black-legged Kittiwakes nested along with the Murres. The colony seems to be about 90% Thick-billed Murres and I couldn't distinguish any difference in where the Murres were nesting. An occasional common murre could be seen. I went back up the valley around the hill to the S, and then over the next hill back
