Results of seasonal difference between pre- and post-breeding migration in four EAAF migratory sandpipers
| Sanderling | Turnstone | Great Knot | Curlew | |
|---|---|---|---|---|
| n | 12 | 60 | 7 | 9 |
| (i) Migration speed | ||||
| Traditional | V = 78 ( p = 0.000) | t 59 = 12.2 ( p = 0.00) | V = 17 (p = 0.688) | V = 45 ( p = 0.004) |
| Partial | V = 78 ( p = 0.000) | t 59 = 2.7 ( p = 0.010) | V = 10 (p = 0.578) | V = 0 ( p = 0.031) a |
| (ii) Number of staging sites | V = 0 ( p = 0.003) | t 59 = −4.9 ( p = 0.000) | V = 2.5 (p = 0.424) | V = 3.5 (p = 0.129) |
| (iii) Total migration distance | V = 20 (p = 0.151) | t 59 = −2.44 ( p = 0.018) | V = 0 ( p = 0.016) | V = 8 (p = 0.353) |
| (iv) Maximum step length | V = 75 ( p = 0.002) | t 59 = 6.23 ( p = 0.00) | V = 4 (p = 0.109) | V = 15 (p = 0.059) |
aFor three Curlews migrating around the equinox their timing of migration and there with their partial migration speed could not be determined with sufficient accuracy, resulting in a sample size of 6 instead of 9 for this variable
Paired-t test was used for Turnstone and Wilcoxon signed rank test was used for the other three species. n depicts sample size. Significant results (p < 0.05) are highlighted in bold
