Antbirds wont even cross tracks when they follow ant swarms.

Well, several didn't make the grade with SACC: HBW Special Volume: new Amazonian species.Does this mean I don't have to see 7 "Lineated Woodcreepers", 5+ "Curve-billed Scythebills, XX "Yellow-margined Flycatchers" and so on?! I seem to recall the HBW special volume "new species" skated over the headwaters issue, perhaps with the exception of the paper on the Tolmomyias.

...provided they graduate successfully.Stable hybrid zones are no barrier to recognition as BSc species AFAIK.
