Taxonomic Notes
The often reported last record of the Atitlán Grebe is 1986 (e.g. Hume & Walters, 2012:65). However, extensive personal observations by (Hunter, 1988) in 1986-7 failed to observe a single individual on Lake Atitlán, to which it was apparently endemic. In addition, three individuals of [i]P. podiceps[/i], all male, manifested possible signs of hybridization with [i]P. gigas[/i] (i.e. heavier weight and larger bills than expected for [i]P. podiceps[/i]) (Ibid.).
