Humans rarely get to do more than admire birds from a distance — watching winged visitors at bird-feeders, observing their behavior through binoculars or listening to their calls in the canopy above. 

One exception to this rule is bird banding — the act of safely catching, measuring and marking birds. Banding provides crucial information about bird species, populations and health. It also allows human participants a rare chance to hold a songbird, measure its intricate wings and even feel its tiny heart thrumming against their palms.

Audubon Rockies operates four banding stations in Wyoming. At the stations, researchers and volunteers catch birds in mist nets, determine age and gender and take measurements before affixing them with a tiny leg band. Banding takes place in the summer. 

Cheyenne photographer and bird fan Peter Arnold sits on Audubon Rockies’s board of directors, and has photographed several banding events.

Sometimes a rare visitor even shows up, such as this Calliope hummingbird. The Calliope is the smallest bird found in the U.S.; the tiny  traveler flies more than 5,000 miles each year from its breeding grounds in northwestern states to Mexico and back again. 

The public is invited to attend bandings. Once measurements are logged and the bird receives its leg band, it is released unharmed.

Once measured and fitted with a small metal band around their legs, banded birds, like this yellow warbler, are released. (Peter Arnold)

WyoFile's goal is to provide readers with information and ideas that foster constructive conversations about the issues and opportunities our communities face. One small piece of how we do that is by offering a space below each story for readers to share perspectives, experiences and insights. For this to work, we need your help.

What we're looking for: 

  • Your real name — first and last. 
  • Direct responses to the article. Tell us how your experience relates to the story.
  • The truth. Share factual information that adds context to the reporting.
  • Thoughtful answers to questions raised by the reporting or other commenters.
  • Tips that could advance our reporting on the topic.
  • No more than three comments per story, including replies. 

What we block from our comments section, when we see it:

  • Pseudonyms. WyoFile stands behind everything we publish, and we expect commenters to do the same by using their real name.
  • Comments that are not directly relevant to the article. 
  • Demonstrably false claims, what-about-isms, references to debunked lines of rhetoric, professional political talking points or links to sites trafficking in misinformation.
  • Personal attacks, profanity, discriminatory language or threats.
  • Arguments with other commenters.

Other important things to know: 

  • Appearing in WyoFile’s comments section is a privilege, not a right or entitlement. 
  • We’re a small team and our first priority is reporting. Depending on what’s going on, comments may be moderated 24 to 48 hours from when they’re submitted — or even later. If you comment in the evening or on the weekend, please be patient. We’ll get to it when we’re back in the office.
  • We’re not interested in managing squeaky wheels, and even if we wanted to, we don't have time to address every single commenter’s grievance. 
  • Try as we might, we will make mistakes. We’ll fail to catch aliases, mistakenly allow folks to exceed the comment limit and occasionally miss false statements. If that’s going to upset you, it’s probably best to just stick with our journalism and avoid the comments section.
  • We don’t mediate disputes between commenters. If you have concerns about another commenter, please don’t bring them to us.

The bottom line:

If you repeatedly push the boundaries, make unreasonable demands, get caught lying or generally cause trouble, we will stop approving your comments — maybe forever. Such moderation decisions are not negotiable or subject to explanation. If civil and constructive conversation is not your goal, then our comments section is not for you.

  4. Well, this is fun. Those calliopes are beautiful critters, but like all hummingbirds, believe they’re the toughest guy in the valley.

  5. We also noticed Calliope hummingbirds (for the first time, I think) at our house east of Laramie.
