TABLE 2. Examples of feather scores for primary molt sequence of Rufous Fantails based on individuals captured on 
Saipan in 2009 and 2010 (following Rohwer 2008). Two examples of each primary center are shown. Numeric values 
represent proportion of feather growth: notations are Nodal (N.) and Terminal (T). and arrows above notations indicate 
sequence direction.

distal to P 3, when calculated according to 
primary center number (P 3/4 scoring 3.5). 
Younger (SCB) birds were more likely to 
initiate primary molt among primaries 2-4 than 
older (DCB) birds with a mean starting point of 
2.01 versus 1.54 for older birds (ANOVA, C 2 , m 
= 4.03, P — 0.019). Females (mean starting point 
2.22) were more likely to initiate primary molt at 
primaries 2-4 than males (mean starting point 
1.48: F 2 , 54 = 8.30, P = 0.006; Table 1). Mean (± 
SE) wing chord among 31 males of our sample 
was 67.1 ± 1,41 mm and mean wing chord among 
22 females was 63.9 ± 1.73 mm (F XM = 57.32. P 
- 0.000). Mean mass among 29 males was 8.4 ± 
0.43 g and moan mass among 22 females was 7.9 
± 0.37 g. (F )i49 = 14.44, P = 0.000). Wing chord 
was also significantly longer among 81 DCB birds 
(65.9 ± 1.96 mm) than among 62 SCB birds (64.7 
± 2.42 mm; mo = 5,62. P - 0.004), but mass 
did not differ with age among 79 DCB (8.1 + 
0.47 g) and 62 SCB (8.0 + 0.45 g) birds (F U40 = 
1.55, P = 0.216). The effects of age (P = 0.052)
