Partial Bayesian phylogenetic tree depicting the inferred genetic relationship among fusion gene sequences for 92 APMV-1 isolates originating from samples collected from wild birds in North America and defined as class I sub-genotype 1d or undesignated within class I. The Bayesian posterior probability for this major clade is indicated to the left of the first node. Sequences generated for this study are indicated with asterisks (***). Taxonomic order of host (Anseriformes = square, Charadriiformes = triangle) and region of sample collection (Alaska = red, West = orange, Midwest = blue, Gulf Coast = black, East = green) are indicated
