7/18 Found pure white RTTB egg outside crashing this nest. Definitely not Arctic terns. Too round & chalky. Too well developed to collect. 7/20 Found RTTB incubating mostly her own eggs. Red-throated diver egg. Am fairly certain that it it was shearwater compact quite oval, it was almost circular - more elliptical & smoother & glossier than RTTB egg. Also found RTTB [illegible] brown Common molly egg along with her own (her own well developed) nearest Common molly nest 25yds away. 7/19 6 Fairy terns in Muis (?) in triangle of vegetation between airstrip. Legs 1 broad bandel (06) 2 Fairy terns (1 breeding pair, 06) in (pine?) 100 yds. from small boat pier. TOTAL FAIRY TERNS - 8
