Aim: To examine the history of diversification of ‘blue’ cardinalids
(Cardinalidae) across North and South America. Location: North America
(including Middle America) and South America. Methods: We collected 163
individuals of the 14 species of blue cardinalids and generated multilocus
sequence data (3193 base pairs from one mitochondrial and three nuclear
genes) to infer phylogeographical structure and reconstruct
time-calibrated species trees. We then estimated the ancestral range at
each divergence event and tested for temporal shifts in diversification
rate. Results: Twenty-five lineages of blue cardinalids clustered into two
major clades: one confined to North America, and a second concentrated in
South America. Blue cardinalids probably originated in North America, but
reconstructions were influenced by how migrant taxa were assigned to
biogeographical regions. Most of the pre-Pleistocene divergences between
extant taxa occurred in the North American clade, whereas most divergences
in South America and adjacent Middle America occurred during the
Pleistocene. Despite these differences, the rate of diversification for
both clades has been similar and relatively constant over the past 10
million years, with little geographical exchange between North and South
America outside the Panamanian isthmus region. Main conclusions: Our
reconstruction of the diversification history of blue cardinalids
indicates a role of both Neogene and Quaternary events in generating
biotic diversity across North and South America. Although ancestral area
reconstruction suggests a possible North American origin for blue
cardinalids, the occurrence of seasonal migration in this group and their
relatives limits inference. Our study highlights the importance of
considering ecological and behavioural characteristics together with
palaeogeological events in order to gain an understanding of the
diversification history of widespread, mobile taxonomic groups.
