DENVER - Birds are helping scientists understand the impacts of rapid population growth and climate change in Colorado and across the West, thanks to a crowd-sourced "citizen science" project.
John Sanderson, director of science for The Nature Conservancy in Colorado, said that when non-scientists capture images of birds and upload them to eBird, a mobile app developed by Cornell University, they're contributing to a growing database that gives scientists and bird fans access to real-time data on populations across the globe.
"Birds play critical roles in our ecosystems by eating insects, by distributing seed and by telling us what changes are happening in these ecosystems," Sanderson said.
Bird sightings contributed by hundreds of thousands of amateur scientists have helped create a map showing where migrating birds are landing and when they're arriving, Sanderson said. Conservationists and officials, he said, then can use that data to prioritize the most important habitat areas to protect.
Sanderson said climate change has altered the seasonal cycles of plant and animal life, which can threaten food sources for birds along migration routes when their favorite rest stops are out of sync with hatching insects, blooming flowers and fruiting trees. He noted that the Swainson's hawk, widely seen across Colorado during the spring breeding season, spends its winters in Argentina.
"As that bird's moving from Argentina north, it has to stop in many places along the way and refuel," he said. "If it can't find places to stop and refuel, it will run out of energy and not be able to complete its migration."
Sanderson said data from this spring's migration season shows how birds are responding to changing weather patterns and loss of habitat because of development. Rising temperatures have caused birds to seek ranges further north, in higher elevations and along cooler rivers, streams and wetlands. Bird fans can learn more about contributing to the project online at eBird.org.

After years of trying and failing, Indiana lawmakers have put bobcats in the crosshairs.
The decision forces the Indiana Department of Natural Resources to create the hunting season framework and ignited fierce debate among lawmakers, wildlife advocates and hunters regarding the necessity and ethics of targeting Indiana's only native wild cat species.
Samantha Chapman, Indiana state director for The Humane Society of the United States, argued the bobcat population is still in the process of recovering in Indiana.
"Throughout the committee process, it was very clear that the hunter and trapping lobby had a lot to do with this bill," Chapman asserted. "Folks have even mentioned wanting to eat bobcats, which to me seems absolutely preposterous."
Chapman stressed experts need scientific data before targeting the wild cats. Proponents claim they are having issues with disappearing cottontail rabbits and said the bobcat population is getting out of control, especially in southern Indiana.
Sen. Scott Baldwin, R-Noblesville, authored the bill. He said the DNR has many people with varying opinions, and they sometimes need to be nudged.
Ernie Nichols, a member of the Indiana State Trappers Association, encouraged lawmakers to eat bobcat meat.
"First off, tastes great. I don't know if you've ever had a chance to eat it but it's delicious," Nichols stated. "Second off, on the state DNR website from calendar year '22 to '23 there has been a 118% increase in confirmed bobcat sightings."
Opponents claim hunters want to take the cats for the fur or a trophy and argued wildlife belongs to all Hoosiers and should be held in public trust. The DNR has remained neutral throughout the contentious debate and is tasked with creating the new season to hunt and trap bobcats, possibly as soon as July 2025.

A Utah wildlife expert considers wild animal poaching to be a significant problem in the Beehive State, following several incidents of game animals being killed and then left to waste.
According to the Utah Division of Wildlife Resources, four deer were killed in the Woodland Hills area of Utah County late last year. The heads were removed from each deer, and the carcasses were left. More recently, the division discovered a cow elk and 18 geese dead in Emery County.
Capt. Chad Bettridge, law enforcement officer for the Utah Division of Wildlife Resources, said the hunters responsible for these killings could be charged with a felony.
"Three very different circumstances and potentially even more than that," Bettridge noted. "We are not 100% sure that all the deer in Utah County were tied together, but they were in such a location and were similar in circumstance that it does kind of feel like they were maybe done by the same people, or at least related."
Bettridge encouraged anyone with information which could be useful to contact the division by using their law enforcement app. It allows you to send text messages, photos and GPS locations of any situation you think might be illegal. You can also use their 'turn in a poacher hotline,' at 800-662-3337.
Bettridge pointed out in the past five years, the number of animals killed illegally has ranged between 1,000 and 1,400. He added Utah is a big state, and as he put it, the agency does not have "an incredible amount of officers" to cover the vast landscape. When they're fully staffed, there are about 50 officers in the field to investigate reports of animal killings.
"For example, the cow elk in Emery County, that cow elk was shot during a time that it could have been a legal season for cow elk," Bettridge recounted. "However, only a small amount of the meat was taken from the carcass and everything else was left to waste, which makes it illegal, even if you had a license to legally kill that elk."
Bettridge acknowledged the majority of hunters and fishermen are doing the right thing, but said there are bad actors out there. He added the division depends on the public to help by reaching out if they come across something potentially illegal and in need of a closer look.

A federal court ruling that limits wolf trapping and snaring in Idaho could aid recovery of grizzly bears in the region.
U.S. Judge Candy Dale ruled that the state needs to cut back on wolf trapping and snaring because of its impact on grizzly bears, which are listed as threatened under the Endangered Species Act.
Jeff Abrams, wildlife program associate with the Idaho Conservation League, said a bill passed in Idaho in 2021 expanded trapping and snaring of wolves and likely led to the judge's decision.
"The decision plainly concludes that there's no way to set a trap or a snare in a way that will only capture a wolf," said Abrams, "and state incentives for this activity make the problem even worse."
Under the ruling, wolf trapping season will close between March 1 and November 30 in eastern and northern Idaho.
In response to the decision, Idaho Fish and Game Director Jim Fredericks said the state has expanded wolf snaring cautiously and the agency is considering its legal options.
While grizzlies have made a comeback in parts of Idaho, Abrams said they've been absent in the central section of the state, known as the Bitterroot.
"That recovery zone does not have bears in it right now," said Abrams, "and this ruling very much impacted our ability to begin to work to restore bears in that habitat."
Abrams said he believes lawmakers have been single minded in the their approach to wolf management, expanding it too far.
"The right to trap is guaranteed in Idaho but not if it might impact or harm protected wildlife species," said Abrams. "It also risks the goodwill of a lot of Idahoans that generally support the idea of trapping."
