Lehner R. 1965 Jan. 10 picked up trapped mice; caught 15, two were marked, 13 were autopsied; set traps again across east side of island after supper; saw a Christmas Island Shearwater flying back and forth across the east shore (a band was visible); this is the first one seen this year. Jan. 11 picked up traps and mice for autopsy; autopsied 14 mice, making a total of 40 for the month; the population of mice appears to be lower this month than in Dec. and Nov. as our overall trapping success is lower.
