Table 2.
GLMM of the relationship between FID and territory identity (random effect), susceptibility of prey to predation (covariate), whether the observation was made within 100 m from or more than 500 m away from the nest (distance to nest; fixed effect), body mass (covariate), the interaction between susceptibility and distance to nest and hawk species

| Hawk species | 3.60 | 1, 28.2 | 0.07 | 0.025 | 0.013 |
| Susceptibility × distance to nest | 9.75 | 1, 926.9 | 0.0019 | −0.042 | 0.014 |

Notes: The random effect of territory size had a variance of 0.0028 (SE = 0.0011), 95% CI 0.00059, 0.00503, accounting for 6.3% of the variance while the random effect of species had a variance of 0.0079 (SE = 0.0032), 95% CI 0.0016, 0.0143, accounting for 17.9% of the variance.
