R.S. Lawrence 1964 Black-Footed Albatross Lionfish Black-Foots were about the same stage as Laysan Albatross, perhaps slightly older. Fewer parents were noted feeding Black-Foot chicks than Laysan. The Black-Foots were confined almost exclusively to the beach area. Actual count on 14 June = 993 chicks + 10 adults. Since most of these were along the beach area which was covered very well in this particular survey, I would imagine 100 more or so about very else. Adults come and go, so no way of estimating these. For all practical purposes, there are no adults on the island, as their only reason for coming in is to feed the chicks.
