TABLE 3.

Phylogenetic regression coefficients and fit statistics for the relationship between the aspect ratio and natal dispersal distances among 41 North American bird species using the traditional spread‐wing method and the new folded‐wing method (Ellipse model) for estimating the total wing area.

Method	Intercept	Coefficient a	df	Log(Lik) b	AICc c	t	p	r 2
Spread‐wing Method	−2.12	2.76	2	−50.1	104.2	4.72	>.001	.36

^a Aspect ratios and natal dispersal distances were log‐transformed.

^b Log(Lik) is the logarithm of the maximized likelihood.

^c AICc is the sample size corrected version of the Akaike information criterion.
