The Amchitka Chickadee! Of course! What else could it be? You can thank MARY MINOR, of Anchorage, for identifying it. Frankly I didn't know what it was when I drew it, and now I can add it to my life list.
I hear some of you asking "What is an Amchitka Chickadee?" Amchitka is an island in the Aleutians. It was the site of a number of underground nuclear tests culminating in the Cannikin blast in 1971. The effect on those who were part of the project is still argued about today. Kudos to Mary for explaining the mutant bird with such a surprisingly apt backstory.
We had a wild variety of quality captions spanning topics from Frank's jet to bird flu, a testament to the quirky fertility of the human imagination.
Keep up the good work, we're depending on you.
Your humble servant,
