92. 8 Jan. (cont.) species, although there is no where near the site constancy that is found in Blue-faced Boobies. Behavior this PM revealed both R2 and the ♂ of R22 Sky-calling simultaneously to get the attentions of R22. The unpainted male (painted 04 tonight) is definately winning out, although R22 sits with R2 if the other bird is not around. Painted all the Boobies we could catch fresh, and gave two new birds numbers as follows: 03 - the Sky-callin ♂ at XO 697-24509 04 - the ♂ with R22 667-35059 Both birds were recognized merely by the positions they were in, relative to colony stakes and other birds. In general, all the birds were in the same spots they occupied at dusk, and have been occupying for the last week. One Laysan was found dead next to study nest 33, and was collected. 9 Jan. '65 The shore bird and seal census occupied 4 hours, from 1000 to 1400. The numbers this week were consistent with those found for last week - 732 Laysan nests is a variance of 3 nests. No Sanderlings were seen, 71 Golden Plover, 125 Ruddy Turnstones, 11 Wandering Tattlers - a high figure. Five Glaucus-winged Gulls and 1 Glaucus Gull were seen. Most interesting were the figures on Laysan problems and their back-rot disease. 13 Ad. Laysans, 3 on nests, were found with the disease in various stages. It is easy to tell an incubating bird in this condition, as there is a mass of feathers surrounding the nest, where they were preened out or fell out as the skin rotted away from underneath. Walkers in advanced stages can also be spotted, as they limp, and often one or both wings dropps down. This disease is an vicious one - not only is the skin attacked, but also all connective tissue, muscle, and probably nervous and vascular tissue in the area of infestation. ALL 13 SICK LAYSANS WERE FOUND IN THE SAF - none were seen elsewhere Also found, IN THE SAF, were 8 dead Laysans; those not badly decomposed showed the familiar back rotting, and the others, can be assumed, died for the same reason. Black-footed Albatross - nests found this week were 152 in number, a drop from 190 last week.
