We found that both adults and young Andean condors showed a threefold reduction in the use of the communal roost after the beginning of the rainy season. Using an autoregressive generalized linear model, we associated environmental variables with visual surveys of adult and young condors at three different times of the day and three times a week between June 2014 and March 2015. Here, we provide the first assessment of how daily temperature, rainfall, and seasonality influence surveys of Andean condors on a communal roost in the central Peruvian Andes. Still, there is a need to standardize the surveys based on seasonality and suitable environmental conditions throughout the species distribution. The initiatives rely on extensive population surveys to gather basic information necessary to implement policies and to intervene efficiently. In response, conservation strategies have been implemented in many countries to reverse the increasing extinction risk of this species. However, their populations are declining over their entire distributional range. The condor flew directly over the very spot but saw no shadow of a girl swimming underneath the water, only a frog hopping about.Among the New World vultures, the Andean condor is considered one of the most culturally and ecologically important species. The girl stood up, jumped into the stream, and completely disappeared. Landing on a high rock, the condor shook its beak, a hook powerful enough to pierce the hide of a llama, and shrieked, "Stop it at once, you silly girl! Come back to the cave now!" "She'll make me wait here all day!" The condor flew to the stream where he saw the image of Collyur kneeling over the rocks, beating her clothes. "What's keeping that foolish girl?" hissed the condor after many minutes had passed. The little frog, as the image of Collyur, kept beating the clothes with the same motion. The new Collyur picked up the girl's clothes and resumed beating them against the rocks.Īt once, the real Collyur ran as fast as she could down the mountain to the valley and the shepherd's home. In an instant, the frog changed into the image of Collyur. "We cannot wait a second more," said the frog. She leaned over and kissed the frog on the forehead. "Can you really do that?" Collyur looked with wonder at this little frog, who seemed at that moment to be the most beautiful creature on earth. She dare not even leave the cave even for a moment, for the condor could see her from very far away and swoop down in a moment's time. She also had to prepare huge meals to satisfy the voracious appetite of the condor. The condor brought back its prey, dead vicunas (those are animals in the llama family), and she had to beat the vicuna skins into rugs for the cave nest and into blankets. She had been a shepherdess in her happy livelihood when a condor - a giant vulture with wing spans over 10 feet - had plucked her away and carried her back to its nest high up in the rocky cliff. Not by her choice did she live there, for the girl was a prisoner. Not far from the frog, and feeling just as sad, was a girl who lived in a vulture's cave even higher up in a mountain. She could tell her brothers and sisters didn't know what to make of her, and gave her distance. "If only I had two perfect legs like my brothers and sisters," bemoaned the frog whenever she saw her limping reflection in the water. The frog had been born with a right leg much longer than the left leg.
