Stopover departure decisions in songbirds: do long-distance migrants depart earlier and more independently of weather conditions than medium-distance migrants?

Table 1 Effects of fuel load and day of year on departure probability during the first night following capture in Northern Wheatears, European Robins and Common Blackbirds

Parameter	Estimate ± SE	95% CI	p

Species (Common Blackbird)	−2.399 ± 0.496	0.455/1.486	< 0.001
Fuel load	0.890 ± 0.215	−0.494/−0.072	< 0.001
Day of year	−0.257 ± 0.196	−0.643/0.130	0.193

Average model estimates, adjusted standard errors (SE), 95% confidence intervals (CIs) and associated p-values of parameters included in the candidate models in Additional file 1: Table S2 are shown. P-values < 0.05 are given in bold font. Reference category for species is Northern Wheatear
