Tan Eggs

They resemble rabbits due to convergent evolution

Viscacha or vizcacha (UK: /vɪˈskætʃə/, US: /vɪˈskɑːtʃə/) are rodents of two genera (Lagidium and Lagostomus) in the family Chinchillidae. They are native to South America and convergently resemble rabbits

The data comes from Cascades Pika Watch, a program of the Oregon Zoo that began in 2018 after the Eagle Creek Fire destroyed much of the pika’s habitat.

Every summer, volunteers now go out into the field to watch and listen for pikas at specific locations. They then upload their data online for biologists to better track the population.

Pikas typically live on mountains at elevations above 6,000 feet throughout the western United States. But the new data observed a low-elevation population living in the Gorge, just a half-hour drive from Portland.

According to the zoo, last year’s volunteers spotted pikas at two-thirds of the surveyed sites. But this year, the number was even higher. They added 150 volunteers who submitted 558 surveys from 84 locations throughout the Gorge this year.

“Each season, we’re getting closer to the pre-fire population numbers,” said Dr. Johanna Varner, with the Cascades Pika Watch program. “This is great news for everyone monitoring the Gorge pika population.”
