This non-migratory small Cormorant extends its tropical range into southern Texas and more rarely to Louisiana.
They build strong platforms of sticks in trees of saline lagoons. Nelson says they gather in numbers at foot of rapids and forming a line across the stream, beat up river in a splashing line driving fish before them and so confusing the quarry as to render capture easy. The maneuvre was repeated until all were satisfied, when they returned to the nesting area.
Southern Texas and southern Louisiana.
