Abstract
We reviewed the tremendous architectural diversity of ovenbird (Furnariidae ) nests based on literature, museum collections, and new field observations . With few exceptions, furnariids exhibited low intraspecific variation for the nest characters hypothesized, with the majority of variation being hie rarchically distributed among taxa. We hypothesized nest homologies for 168 species in 41 genera (ca. 70% of all species and genera) and coded them as 24 derived characters. Forty-eight most-parsimonious trees (41 steps, Ci = 0.98, RC = 0.97) resulted from a parsimony analysis of the equally weighte d characters using PAUP, with the Dendrocolaptidae and Formicarioidea as su ccessive outgroups. The strict-consensus topology based on these trees cont ained 15 clades representing both traditional taxa and novel phylogenetic g roupings. Comparisons with the outgroups demonstrate that cavity nesting is plesiomorphic to the furnariids. In the two lineages where the primitive c avity nest has been lost, novel nest structures have evolved to enclose the nest contents: the clay oven of Furnarius and the domed vegetative nest of the synallaxine clade. Although our phylogenetic hypothesis should be cons idered as a heuristic prediction to be tested subsequently by additional ch aracter evidence, this first cladistic analysis of the furnariids demonstra tes the general utility of nest characters in reconstruction of avian relat ionships, and it provides a test of monophyly for several furnariid taxa.
