Birds like Flamingos can stand on one’Ieg. Which among the following statements relating to this is/are correct ? 1. By standing on one leg Flamingos can conserve body heat and energy because they can reduce great deal of surface area for the loss of heat. 2. By standing on one leg, one Flamingo makes a courtship display, which is a part of ritual prior to reproduction. Select the correct answer using the code given below :

Statement 1 is correct as thermoregulation is a primary reason for the one-legged stance. Flamingos lose significant body heat through their long, unfeathered legs, especially when standing in water [t3][t6]. By tucking one leg into their plumage, they reduce the exposed surface area, thereby conserving body heat and energy [t2][t5]. Research indicates that flamingos adopt this posture more frequently in cooler weather and can even support their weight passively without active muscle force, further saving energy [t1][t6]. Statement 2 is incorrect because while flamingos have complex courtship rituals involving synchronized 'dances,' these consist of head-flagging, wing-salutes, and bill-snapping rather than standing on one leg [t4][t7]. The one-legged posture is primarily a resting and thermoregulatory behavior rather than a specific reproductive display [t3][t6].
