The finches thrive in bad weather. When it’s a clear, sunny day Savides knows her likelihood of seeing a finch is slim. But on nasty, snowy, windy days she can count on seeing hundreds of the finches around the feeders.

Most of the bird feeders are on Utah’s beautiful ski resorts such as Alta and Powder Mountain. On blizzard-like days when skiers are choosing to staying home, Savides is heading up the slopes.

Clark Rushing, assistant professor in Department of Wildland Resources in the Quinney College of Natural Resources and principal investigator on the project explains, “To catch these black rosy-finches, we’re travelling to locations when the weather is at its worst. They are extremely hardy birds, how they survive in those conditions is pretty astounding. They are small birds weighing only a few ounces.”

Due to the warming temperatures, the black rosy-finch populations may be at risk.

Scientists fear the finch numbers may be decreasing, based on the reports from bird watchers who say they are seeing much less of the attractive bird. Researchers are concerned it may be a result of climate change.

Rushing explains, “The black rosy-finch has a small breeding distribution confined to very high elevation sites. Climate change may drive this species to smaller and smaller population sizes and possible extinction because as climate warms these sites, where the finches can breed, they will get smaller and smaller. The birds could eventually get pushed off the tops of the mountains with nowhere to go.”

According to the Wild Utah Project, “The black rosy-finch is one of the least-understood birds in North America. We understand little about its reproduction, population status, survival rates, or migratory tendencies.” Without this information wildlife managers can do little to help conserve its population.

Savides’ goal is to assist in gathering enough data so wildlife managers may begin to understand the life cycle of the finch and plan for conservation efforts.

Her project began by setting up mist nets around the feeders to catch the birds. Once caught, the finches were gently held while a micro-chip bracelet was attached to their legs.

Each time one of the tagged finches approaches a feeder, equipped with a radio frequency reader, the bird’s visit is logged.

The finches tagged last year are now returning. The data is beginning to be gathered.

Recognizing the amount of data needed, researchers have expanded the data gathering to include citizen scientists. These are residents of Utah who volunteer to be trained to identify the black rosy-finches. In the winter when the birds come down to lower elevations, in certain parts of the state, residents can report when they see the finches.

Any resident interested in becoming a citizen scientist can go to the Wild Utah Project website and receive more information.

As more and more data are gathered, researchers and wildlife managers can begin understanding the phenology of when the finches come down to lower elevations, when they return to higher elevations to breed, and how likely they are to survive from one year to the next. This knowledge could help with conservation efforts.
