Help with a bird from Pantanal, Brazil (1 Viewer)

[arodris]

Hi,

I need help to identify this bird I saw in Pantanal, Brazil, north to Porto Jofre. The bird was seen last august.

I think it is a Progne species, but not sure about which one.

Thanks

The white chin and throat is good for Brown-chested Martin.
