Flamingo Dance

Algebra Level 2

A flock of flamingos was gathering in a lake. Interestingly, all the birds of each gender acted in harmony within the group. Synchronously, if each male bird stood on one leg, each female would stand on two legs, and if each female lifted up one leg, each male would switch to be on two legs.

At one moment, you photographed the whole flock and counted 71 legs in the water. When the switch happened, you could then count 58 legs in the water.

How many flamingos were there in the lake?
