Azara's spinetails (Aves: Furnariidae). The identity of No. 236 Chicli and No. 237 Cogogo

摘要

The descriptions of birds provided by Felix de Azara (1742-1821) from his time in Paraguay constituted some of the first and most detailed descriptions of the South American avifauna from the period. Whilst many formed the basis for scientific names still in use today, others have remained inconclusively identified. In this paper the identities of two of these descriptions referring to spinetails of the genus Synallaxis are elucidated. There has been considerable disagreement amongst previous authorsas to the correct identity of two of these descriptions. No. 236 Chiclf is shown to refer to Sooty-fronted Spinetail Synallaxis frontalis and No. 237 Cogogo to Pale-breasted Spinetail S. albescens.
