The above definitely establishes the fact that birds do pass from Lifu to Uvea, but leaves much to be de- sired as regards the frequency of the occurrence and numbers and regularity of such movements. The date seems to accord with natives' accounts of increases of numbers on Uvea and visibility and weather seem such as birds would choose for passing from island to island. There are no records of birds being seen leaving Uvea or Lifu, but this probably takes place very early in the morning. I had one or two vague reports on Lifu, of birds arriving at Lifu from a sea- wards direction and one very reliable report from Thocking village in the north of Lifu, of a day when during the morning,, small parties of Columba continued to arrive at intervals (parties of 4 - 8 or 10) for several hours from 8 o'clock or earlier till 10 o'clock, all from seawards. These birds might have arrived from along the coast, but natives seemed to be very definite it was not so, in fact, some said they thought they came from the New Hebrides (not likely). Weather natives remembered was fine, but other points they had forgotten. Considerable difference of opinion about the time of year was expressed, the earliest date given was January and the latest was May but the majority thought it was either January or February or even a little after that. From the above data, scanty and vague as it is, I think it is certain there is an annual movement of a cer- tain number of birds to and from the 2 islands. My own idea is that birds cross to Uvea and breed there, not in large numbers, and possibly others cross but dont breed.
