This is a really nice video of a male Ruby-crowned Kinglet showing his red crown while feeding. At first glance, it’s hard to tell why this bird is called ‘Ruby-crowned’ but you’ll understand about 7 seconds into the clip.

Ruby-crowned Kinglets summer across much of Canada and parts of the western United States. For the most part they winter in the southern half of the U.S. You can see the full range of this bird and more details at Cornell’s All About Birds: Ruby-crowned Kinglet. Looks like we have a chance to see them during the migration as they’ve been reported in our area in April-May and October.
