This bird turned up on a vessel several hundred km east of Argentina in November 2018, it lived onboard for at least a few days, eating insects that had also landed on the vessel. Very active, bouncing and jumping about....

It looks like a spinetail of some sort, but I thought these were not migratory....

Looks something like juvenile azara's spinetail (whitish throat, Reddish wings and tail) but not sure what other possibilities there are. Nor how...

Thanks THE_FERN, I have the plates volume of Birds of Northern South America. The nearest i can get is Plain-crowned Spinetail but this doesn't seem to fit either - the images I have found so far have too much rust in the wing. This bird seems to have a rather limited amount of rufous / rust colour there.

Probably a Sharp-billed Canastero. They have a thin pointed bill, rufous on wings, dark uppertail and rufous undertail. Besides (and in contrast to most furnarids), some of them do migrate so I believe it to be a firm candidate.

Sharp-billed Canastero?
They are migratory (and I've found the chin patches on some of these ovenbirds are not nearly so visible in the field as they are in plates in guides!)

Snap! Motmot posted while I was double checking my field guide

Many thanks, Sharp-billed Canastero fits the bill nicely! What a record though.....hundreds of km offshore.

Worth reporting I'd say, it is really amazing.

Worth reporting indeed. But where? Argentina?

I have A LOT of observations from this area (including three species of passerine). Obviously most are seabirds, and I identified the vast majority - still have some work to do with all the prions though

If if proves relevant/interesting enough you could write a short note for the journal Cotinga.
