| Nest closure (0–1) | 224 | 0.145 ± 0.015b | |
| Nest height (cm) | 224 | 3.752 ± 0.055c | |
| Cotton used (g) | 116 | 1.862 ± 0.081 | |
| Paper used (g) | 106 | 0.761 ± 0.042 | |
| Postpartum | Nest presence (0–1) | 241 | 0.958 ± 0.010a |
| Nest closure (0–1) | 238 | 0.072 ± 0.010b | |

Means are expressed as mean ± SEM. Upper script letters indicate that there is significant difference (P < 10−6) between pre- and postpartum equivalent phenotypes.
