Clapp, Roger 1964 Last night I banded 505 Masked Boobies (largely from an enormous club of 800 or more). And was able to walk erect through them causing only faint disturbance. A very pleasant contrast to Enderbury. A total of about twenty-four interisland recoveries were obtained. None of these birds were neck-ringed. I think that this tends to imply that these birds were not on their islands of banding origin when we came through for our recoery rate was high enough on some of these islands. So it seems likely that at least one out of twenty-five would have been marked. These birds were possibly "visiting" the island on which they were banded when banded. This is highly hypothetical. None of these interisland birds had any trace of "subadult" plumage but the 4-6 whose voices we recorded all have female voices. Also spent some time examining the seawreck for Molluscan fauna. On the West Beach at least this fauna is extremely impoverished. A few morula, a few "Hermit-crab" turbans and three species of small cowries were obtained (one Cypraea caput-serpentis). Two species of Conidae were seen in the sea-wrack. One (a small purplish species; the other was Conus ebraeus. This latter, which on the Phoenix Islands, was one of the commonest forms in the sea-wrack is quite scarce here. I later examined the rook-bordered pools (there are several blowholes) at about noon but the number of living shells were very scant (only two or three seen all encrusted, one a very worn morula). The few other shells seen were inhabited by the hermit crab with blue and black barred legs but shells are at such a premium that one individual was seen to inhabit a much battered and broken shell.
