Summary of polymorphism data and population parameter estimates in populations of Agelaius phoeniceus and A. tricolor.

L = sequence length, n = number of individuals sampled, k = number of unique haplotypes, h = haplotype diversity (s.d. in parentheses here and subsequently), S = number of segregating sites, η = minimum number of mutations ( = S* of [42]), I = number of segregating indel mutations, π = nucleotide diversity [73], θW = Watterson's estimator [73], θπ = Misawa and Tajima's estimator (eqs. 5a and 6a in [42]), θs* = Misawa and Tajima's estimator (eqs. 5c and 6c in [42]). All calculations of Misawa and Tajima's estimators and test used an α = 0.102 for CR, and α = 0.279 for ND2 (see text, Figure 2).
