R.D.Grossin 1966 18-16 4:20-5:30 June. Great Frigate bird Daypan Great Frigates are distributed over the island about as are Red-footed Frigate, concentration everywhere where there are other large shrubs grow. Many (>60%) of the population are white-headed immatures or out- adults. Nesting ranges from advanced incubated eggs to these immatures; the entire population is somewhere between 3 and 500 birds. The birds are nocturnal as well as diurnal, and individuals can be seen and heard coming back to the nest at any time of night. These returning birds usually call a series of word calls as they approach nests, and are often answered by those birds already perched. The nesting cycle is advanced enough so that no displaying but have been noted (i.e., 20 minutes long pouches). A spotty check on 10 June came to 60 nests with one egg, 59 nests with chicks, and 750 nest contents unrecorded (Chen). R.D.Grossin 1966 10-16 5:20-5:30 June. Golden Plover Daypan.
