Agree with Rocksor, the two similar looking Vieja are V. melanurus, could be male and female. The slope of the forehead, is the factor that separates the gender.
And I can't tell what the other Vieja is either.
By the way Vieja are not South Americans, melanurus are from southern Mexico and Guatemala Central(north) America
