The Ovenbirds are a large family of small suboscine passerine birds found in Mexico, Central and South America. Hybridization has been documented in several genera.

At Amazonian headwaters, hybrids between subspecies of the following species have been confirmed genetically (Weir et al., 2015): Plain-brown Woodcreeper (Dendrocincla fuliginosa), Elegant Woodcreeper (Xiphorhynchus elegans) and Wedgebill Woodcreeper (Glyphorhynchus spirurus). Reproductive isolation between Elegant Woodcreeper subspecies is mainly driven by postzygotic isolation (Pulido-Santacruz et al. 2018).
