Southern Screamer

• For all that it looks like a waterbird, it can soar at height on thermals much as a raptor does, thanks to air sacs under its skin.
• It has air beneath its skin: a layer of subcutaneous bubbles that crackles to the touch and gives it buoyancy and insulation, a feature uncommon among birds.
• Its two horny spurs on each wing are real weapons that it uses in territorial fights, and with which it can seriously injure a rival.
• Its alarm call is so loud and so reliable that on the ranches of the Argentine Litoral screamers have been kept loose as farmyard sentries.
