Since publishing the papers below, second karyotyping on one bird (flamingo #98) at the Philadelphia Zoo has revealed that it is male, not female. The following changes are necessary.
Anderson, M. J., Williams, S. A., & O'Brien, E. H. (2009). Individual differences in the preferred neck-resting position of Caribbean flamingos ( Phoenicopterus ruber ). Laterality , 14 , 66–78.
| • | The “Subjects” section (p. 68) should indicate that the flock consists of eight male and nine female birds. | ||||
| • | The sex of Flamingo #98 in Table 1 (p. 72) should read “M”. | ||||
| • | The final sentence on page 71 should read: “No significant sex differences were obtained on the neck-resting index (direction), t(15)=−1.222, p=.240, d=−0.60, but a significant sex difference was demonstrated on the absolute value of neck resting index (preference strength), t(15)=−2.165, p=.047, d=−1.05, with females (M=.301, SD=.119) displaying stronger absolute preferences than males (M=.152, SD=.163).” | ||||
| • | The sixth full sentence on page 73 should read, “No sex differences were observed in neck-resting side preference, which is a finding in line with some primate studies (e.g., Laska & Tutsch, 2000; Marchant & McGrew, 1996). A difference in general preference strength was obtained, however, with females displaying stronger absolute preferences than males, which constitutes a finding deserving of further investigation in future studies.” | ||||

| • | The “Subjects” section (p. 632) should indicate that the flock consists of eight male and nine female birds. | ||||
| • | A change is needed in the first sentence in the last paragraph on page 633: “… (i.e., birds that preferred to rest their necks to the right; n=14; 7 males, 7 females) …” | ||||
| • | A change is needed in the last sentence of the third paragraph on page 635: “… necks to the left (n=1) than to the right (n=7), …” | ||||

| • | Sentence one of the “Subjects” section (p. 569) should indicate that the flock consists of eight male and nine female birds. | ||||
| • | The sex of Flamingo #98 in Table 1 (p. 571), Table 2 (p. 572), and Table 3 (p. 573) should read “M”. | ||||
| • | The sixth sentence of the first full paragraph on page 573 should read: “The pairs consisted of nine male/female pairs.” | ||||
