Hi,

found yesterday at the Centro de Visitantes, Peninsula Valdes, Patagonia, about 20 kms from Puerto Piramides.

According to a 10 year old thread in this forum it might be Chiguanco Thrush (Turdus chiguanco), although it is far off range and in completely wrong habitat.

Any new insight into this bird?

Thanks
Chris

The Chiguanco Thrush has recently invaded the coastal habitats of northern Patagonia, it has to be it.

It is indeed. They're fairly regular now at the latitude of Valdes, and are occasional even further south on the Chubut coast. They're also fairly plastic in their habitat requirements.

Natural colonisation, or derived from escaped captive birds?

It apparently is a natural expansion from what I've read. They seem to be spreading south following the coast.
Some info here (in spanish):

Thanks!

Any significance in the eye ring on this bird being much stronger than illustrated for subsp. anthracinus in e.g. Clement & Hathway Thrushes, or HBW vol. 10?

Check these pictures of Chiguancos from Argentina, some of them with even more distinctive eye rings, I guess it's a variable feature.

It's natural colonisation, yes. The bird here is the expected subsp - anthracinus - in the south. Has richer black and brighter bare parts (eyering especially). You may have seen a female too - browner, duller bareparts. Mostly they look the same across Arg expect right in the NW.

Yes, this is interesting.
Just the Mapa de Distribución should be updated... ;-)
