Tables 8, 9, and 10 present the writer's findings on populations of migratory shore birds in Micronesia in 1945. At Guam, as shown in table 8, the records for March, April and early May are few, owing to a limited amount of field observation. Beginning in late May and until October 24 a greater amount of time was spent in the field and more regular records were obtained. No observations were made by the author at Guam in the period from August 11 to September 25. The dates marked with an asterisk are those on which observations were made on the extensive tidal flats at Agfayan Bay and vicinity. These flats, at low tide, present excellent feeding grounds for waders and in 1945 were undisturbed by parties of service personnel, because the area was "off-limits." Table 8 shows that _Pluvialis dominica_, _Numenius phaeopus_, and _Heteroscelus_ spp. were the shore birds most frequently found at Guam in this period. _Pluvialis dominica_ was the most numerous of the three species. Of _Heteroscelus_ there was approximately equal representation of _H. incanus_ and _H. brevipes_ as indicated by specimens collected. These birds were not identified to species in the field.
