28 June 1964 (cont.) 25 Back on SAND ISLAND, Midway A. # P.M. - after dinner we looked at Red-tailed Tropic Birds. I got bit by one from the campsite. Did you know - the young of this species are dimorphic too - some have white, some are BROWN! What goes well these nestsides. Nothing in the same way. Color phases - no dark phased Wedge-tail shearwater on Oahu or other Islands, none yet in Wherry + Line Islands. Saw one on dark phase in Red-footed Boobies. All 56 Wedge-tail sheared were normal color phase.
