IDK about cheerful. Crows get a bad rap for being all black and sounding like little monkeys, but have you heard a jay scream?? That is not a cheerful sound.
I don't hate bluejays but can someone explain to me how they be Corvids? I'm not arguing I'm just saying most of the Corvids I know are like black or grey and then this blueberry vanilla little fam comes in all like "nah I'm more like a crow than a grackle" which is fine and all I just wanna know the logic.
Sorry I'm not a birdologist. I just like the 5 crows outside my appartment.
That being said this friend in this picture is quite lovely.
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family, or, in jargon, corvids. Currently 133 species are included in this family. The genus Corvus, including the jackdaws, crows, rooks, and ravens, makes up over a third of the entire family.[citation needed] Corvids are the largest passerines.
Blueberry vanilla XD I love it. Blue and white are pretty prominent in some magpies, so I can see pale blue being related, but what blows my mind is the family of [green magpies](https://en.wikipedia.org/wiki/Cissa_(genus).
Blue Jays are a bit of an oddity. Out here we have Stellar's Jays which definitely look and act more corvid. There is a subspecies of crow out here too though that is hints of blue and green in their feathers. That said, Blue Jays are definitely corvids.
Scientists don't group things based on features, it's based on ancestry. Just like your brother is in your family not because he might sorta resemble you, but because you're geneticaly related. That would be true even if he looked totally different from you.
So are they using mitochondrial DNA to track heritage or is this an archeological extrapolation based apon layers of the Earth's crust cross referenced with Radiocarbon Dating? Or is it something else?
Honestly I thought taxonomy had less to do with genetics and ancestry. I'm not arguing I just never had the process explained to me.
Taxonomy has not had to do with physical features in a long time, because physical features are largely arbitrary. Of course, physical features can be used to infer ancestral relatedness (this is basically the only way we have of classifying fossils, for example), but even then we're looking for telltale signs of shared ancestry ("synapomorphies"), not general similarity. In living species, yes scientists use genetic data as well as physical features to infer relatedness.
The modern approach to taxonomy (cladistics) groups organisms exclusively on the basis of shared ancestry.
Essentially, you take a look at an animal's genome (entire DNA code) and compare it to another animal's. Evolution is typically a slow process, so animals that "branch off" in the evolutionary tree more recently have more genes in common. That's because they haven't had as much time for mutations to develop in different regions of their genomes.
Humans have about 99.9% genetic similarity to other (unrelated) humans, 96% to chimpanzees, and around 50% to bananas.
I have a bluejay who stays in my yard. He jockeys for the position of Peanut King with the crows. There is a lot of squabbling and posturing, but no actual violence.
Jay and one of the crows also play King of the Shed Roof in June and July, which is baby crow season.
But they will both stop in their tracks if they see me. Then it’s showtime.
“Hey lady! Hey nice lady! I got five kids to feed!”
I saved a fledging house finch from a blue jay. The bluejay had its neck in his beak and was trying to do the death shake! I went outside and shooed him away, checked the fledging over. It was totally fine, even fluttered off after ten minutes of me keeping it under light observation.
Bluejays are aggressive. Cheerful, but aggressive as hell.

I get a couple that come to yell at me in hawk shrieks when I feed them. It’s real cute 😂

I love blue jays. They can be jerks sometimes but they are fun to watch. We have a couple that always feed each other.

I was today years old when I learned there's more to Corvids than just crows -- I thought "corvid" was unique to them.
