Bare-throated Bellbird. Procnias nudicollis
Brazil. Iguaçu. Bird park.
Procnias nudicollis is known from a wide area of east Brazil (Alagoas south to Rio Grande do Sul and inland to south Mato Grosso), north-east Argentina (Misiones, with one record in Corrientes) and east Paraguay (west to Concepción)1,7,8. The species is considered extinct from remnant forest patches of north-eastern Brazil north of the São Francisco river, where it was formerly known from the Murici area11. It is locally relatively common in Brazil11 and Paraguay (especially in Canindeyú, San Pedro, and Amambay)15, but rare in Argentina14, in the canopy and borders of Atlantic forest up to 1,000 m. The species is believed to be migratory in south-east Brazil, although its migratory patterns are poorly-known and likely to be complex. Similarly, records in Misiones, Argentina, suggest that it is only transient in this country6. Only in north-eastern Paraguay is the species believed to be resident6, where it is locally common at a few isolated sites.
