Malg 1960 Lagodroma minor No. 9 according to the map, at its N. end it was estimated to be 300 feet high but for 2/3 of its length it was 500 or more. The rock reminds me of N.Y. palisades + may be agree with them but its important characteristics as far as the petrels are concerned is the fact that it is very much fractured + crumbling, thus forming numerous cavities for nest sites. The birds were in evidence flying about the face of the cliff + as one watched it became obvious that there were great numbers of them. They could be heard squawking from the cliffs in a call that can best be described by saying it is similar to Donald Duck. It is a grating, low-pitched roar (the best I can do) It was emitted by single birds when we were near the nest or by a bird when its mate - or another bird joined it. We found a number of nests. One that I saw at 3 in a burrow + a w one bird. Three were shallow, about 1-2 feet deep; the birds were easily taken. Two were quite deep - 4 feet + harder to get at. One of these had been blocked in snow + it was evident that the petrel had cleared out the snow to get in. The birds remained in their cavities when
