lings of all three species were more heavily infested with Ornithodoros 
than were adults. • All Ixodes encountered were likewise on immatures or 
nestlings. Most species of birds present (except shorebirds and Laysan 
Teal) were checked for incidence rate of any ticks. Berlese samples

were collected from nesting areas of all nesting species.

The status of this species was practically identical on both islands. 
Practically 100 per cent of the individuals present were birds of the year. 
No adults were observed on Lisianski but on Laysan an occasional adult was 
seen to come in and feed a young bird. While banding birds at night on 
Laysan a few adults were encountered standing by chicks. The feet of adult

birds tend to be pinkish as opposed to the grayish black feet of immatures. 
The young birds varied greatly in weight. Many of the smaller, down-covered 
individuals were practically emaciated and undoubtedly will not survive. 
The larger, stronger individuals were practicing their flying and an occasion 
al individual was seen to fly out and settle on the water. Take off from 
the water by these individuals appeared to be quite easy. 
Birds were distributed over the island pretty generally in all types 
of cover. There was more congregating in open areas and more invasion of 
the beach areas during the daytime with a withdrawal* back into the ocaevola 
at night. A considerable number of carcasses was noted on Laysan but rel- 
atively few were found on Lisianski.
