The evolution of migration in birds has fascinated biologists for
centuries. In this study, we performed phylogenetic-based analyses of
Catharus thrushes, a model genus in the study of avian migration, and
their close relatives. For these analyses, we used both mitochondrial and
nuclear genes, and the resulting phylogenies were used to trace migratory
traits and biogeographic patterns. Our results provide the first robust
assessment of relationships within Catharus and relatives and indicate
that both mitochondrial and autosomal genes contribute to overall support
of the phylogeny. Measures of phylogenetic informativeness indicated that
mitochondrial genes provided more signal within Catharus than did nuclear
genes, whereas nuclear loci provided more signal for relationships between
Catharus and close relatives than did mitochondrial genes. Insertion and
deletion events also contributed important support across the phylogeny.
Across all taxa included in the study, and for Catharus, possession of
long-distance migration is reconstructed as the ancestral condition, and a
North American (north of Mexico) ancestral area is inferred. Within
Catharus, sedentary behaviour evolved after the first speciation event in
the genus and is geographically and temporally correlated with Central
American distributions and the final closure of the Central American
Seaway. Migratory behaviour subsequently evolved twice in Catharus and is
geographically and temporally correlated with a recolonization of North
America in the late Pleistocene. By temporally linking speciation events
with changes in migratory condition and events in Earth history, we are
able to show support for several competing hypotheses relating to the
geographic origin of migration.
