    This was quite an interesting and informative article. Logically, I get how ranges shift, especially as our climate changes. I’ve not read anything directly about it. This is such an interesting example of hybridization.

    The bird had blue feathers on its back and tail and white spots on its wings, similar to a blue jay. But it lacked a blue jay’s spiky crown and had a spot over its eye that is one telltale sign of a green jay. The outlier followed a flock of blue jays and made similar calls. But it also produced the clicks and rattling vocalizations of a green jay.

      I wonder too… here we have an overlap between scrub jays and Steller’s Jays, but they look close enough that it would be tough to spot a hybrid.

      Hybrid:

      Little darker gray, virtually no white, and a hint of the Steller’s crest on top.
