A quasi-experimental approach using telemetry to assess migration-strategy-specific differences in the decision-making processes at stopover

Table 2 Normal linear regression models on species-specific difference in the nocturnal departure timing for (a) all birds, redstarts (n = 14) and robins (n = 21) and (b) birds departing during the first night after capture, redstarts (n = 6) and robins (n = 7)

Parameters	Estimate ± SE	t-value	p	R²	F
(a) Model_{all birds}				0.21	8.9
Intercept (redstarts)	2.090 ± 0.065	32.00	< 0.0001
Species (robins)	0.251 ± 0.084	2.98	0.0054
(b) Model_{departing during the first night after capture}				0.71	12.2
Intercept (redstarts)	2.03 ± 0.099	21.87	< 0.0001
Species (robins)	0.46 ± 0.135	3.77	0.0037
Energy stores (scaled)	− 0.12 ± 0.058	− 2.13	0.0591

In both models, nocturnal departure timing was log10-transformed. Estimates, standard errors (SE), t-values and associated p-values of all parameters are shown. Significant effects are given in italics
