TIL there were green jays.
The rest of it is also interesting

Welcome to /c/birding, a community for people who like birds, birdwatching and birding in general! Feel free to post your birding photos or just photos of birds you found in general, but please follow the rules as outlined below.

This should go without saying, but please be nice to one another. No petty insults, no bigotry, no harassment, hate speech,nothing of that sort! Depending on the severity, you'll either only get your comment removed and a warning or your comment will be removed and you will be banned from /c/birding.

This is a community for posting content of birds, nothing else. Please keep the posts related to birding or birds in general.
-
When posting photos or videos that you did not take, please always credit the original photographer! Link to the original post on social media as well, if there is one.

Absolutely no AI-generated content is allowed! I know it has become quite difficult to tell whether or not something is AI-generated or not, but please make sure that whatever you post is not AI-generated. If it is, your post will be removed. If you continously post AI-generated content, you'll be banned from /c/birding (but it's obviously okay if you post AI-generated stuff once or twice without knowing you did so).

Please provide rough information location, if possible. This is a more loosely-enforced rule, especially because it is sometimes not possible to provide a location. But if you post a photo you took yourself, please provide a rough location and date of the sighting.

There's also some anthropocentric assumptions in that article. It refers to the two species' mating as a mistake multiple times. But horizontal gene transfer, while resulting in higher mortalities of offspring, also has the potential to combine unique evolutionary solutions from different lineages into a single species. Just because it's atypical doesn't mean it's a mistake.

This stood out to me in the article. I even repeated it later to my partner later when talking about it. I'm very curious what the science says about this if it deviates from what they implied in the article.
This study explores a representative example of it across species of fishes. If you want a deeper dive try searching for HGT and synteny index.
Edit: Also conspecifics are members of the same species, while congenerics are members of the same genus. Another relevant search term.
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.
I really really really really can't wait to see a Stellar Jay sometime. They look so rad.
They are absolutely gorgeous in person.
I visited a friend out in the mountains of Idaho a while ago and they were everywhere there. Never got sick of seeing them though, they're beautiful

You've been eaten by a Grue Jay
Have they tried shining a UV light on it to see whatever other possible hidden vibrant color patterns might show up?
Gorgeous.
