^aPaired-end libraries with insert size of 500 bp were used for resequencing. Samples were from eight crested ibis and five little egrets.

^bThe population mutation parameter θ_S = K/aL, a = 1 + 1/2 + … + 1/(n-1), where K is the number of variant sites found by sequencing n chromosomes in a region of length L.
