This species was only discovered in 1926 on the banks of the rio
São Francisco near
Januária in Minas Gerais but, apart from a sighting in 1977,
it has not been seen again at the original site.
In 1993 it was found at a site near Pirapora about 200 km south
but still on the rio São Francisco.
We found 3 birds that spent most of their time about 25 metres up
in the canopy of a small
group of trees on the banks of a stream called the Corrego dos Ovos.
On one occasion a bird dropped down to within a few metres of us
but unfortunately
did not show well enough for a decent photo.
Another pair of birds was seen a few hundred metres away but it
seems to be very scarce indeed.

Areeira,
Astronium urundeuva

active as per Sept.2010)
Its
habitat is probably the most threatened in central Brazil
owing to its valuable
Areeira, Astronium urundeuva, wood and relatively fertile
soils.

Charcoal-burners were fully active at the type-locality in
1986, where there was also
extensive forest cutting for pasture and agricultural development.

The São Francisco basin is also threatened by limestone
quarrying and a large-scale
irrigation project that has already resulted in the loss of
large areas of forest.
