It’s not unusual to spot a Cassin’s finch, which spends most of its time high in the mountains, flitting in Wyoming’s lowlands this time of year. But it’s a special treat to spot an albino version.

Casper birder Zach Hutchinson discovered a pair of the species — both adult males — in his backyard recently and was delighted at the opportunity to observe the contrasting plumage.

“Seeing this species exhibiting albinism is a special sight,” Hutchinson told WyoFile via email. “This is not terribly common in wildlife, as often these animals have associated health issues or are at greater risk from predators and weather conditions.”

To avoid flushing the birds, Hutchinson remained indoors and shot these images through a pane of glass. The encounter was brief but helped fuel his anticipation for spotting migratory birds on the move this spring. The “early singers are in full bloom,” Hutchinson said. “It’s my favorite time of year.”

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.

  1. Albinism, leucism, whatever. Great pictures Zach. Your windows must be cleaner than mine. Looks like you have some new fans.

  2. This Cassin’s finch is not displaying albinism since there is color in the birds eyes. Where some of the color is missing in the bird’s feathers the term for this in is Leucism resulting from defects in pigment cells. Leucism can result in some feathers without color pigment showing white or if the feather has multiple colors the one affected color pigment would be white

  3. What a great way to start the day, reading about beautiful finches in a wintry Casper spring. And one exhibiting albinism! Lovely. Thanks for that, Mr. Bleizeffer.
