Perhaps I'missed it, but I don't see anything about California jays hiding food and coming back for it in a short time. They will hide unshelled peanuts in shrubbery, in the grass or other places. When hiding peanuts in the grass, they will fetch a leaf (sometimes several feet away) place the leaf over the peanut, and adjust the leaf a time or two. They leave and return in a short time which seems to indicated that hiding the peanut is necessary because they can carry only so much at a time.

The photo of the "leucistic" blue jay...? I don't understand how a bird that has no pigment can properly be called leucistic, which seems to be a pigment abnormality. 66.68.84.208 23:45, 10 April 2007 (UTC)dc-a
- True. One has to use this expedient way of putting it though, as there is no special term for loss-of-structural-coloration. (leucistic animals do have some pigment - the bird in question has black for example).
- I'm thinking about a better way to put it. Dysmorodrepanis ( talk) 11:45, 15 February 2008 (UTC)
"However, this may not be as common as is typically thought, as only 1% of food matter in one study was compromised by birds.[10]" Citation 10 does not say anything on that subject, as far as I can tell. 67.174.68.249 ( talk) 15:35, 22 September 2012 (UTC)
How are bluejays only on the east coast, we have blue jays in British Columbia? —The preceding unsigned comment was added by TotallyTempo ( talk • contribs) 04:18, 24 January 2007 (UTC).
Yeah, we have them in San Diego too. What's up with the map?
- Let me guess - they are absent in summer? The species is spreading NE, and "spilling" over the Rockies as of recently, roughly in the Seattle/Vancouver area and surroundings. 2 decades ago, one would probably have seen a Blue on the West Coast once in a decade if at all. Expect them to become a common resident west of the Rockies in our lifetimes. Dysmorodrepanis ( talk) 11:49, 15 February 2008 (UTC)
Central Californian coast has had blue jays since at least 1980 and probably a lot longer. "Nowadays" doesn't seem like the appropriate word. Eddietoran ( talk) 20:56, 25 April 2009 (UTC)
there is an Portuguese article of it,"Gralha Azul",someone can put it there?(I don't know how,tanks in advance.
- See pt:Gaio-azul - as Portuguese is not a widespread language in the bird's range, it is best put on the Portuguese Wikipedia. Dysmorodrepanis ( talk) 12:07, 15 February 2008 (UTC)
There are three closely related blue jays native to North America. The pictured one is an Eastern Blue Jay. As the article states, it lives east of the Rocky Mountains, i.e.the eastern two-thirds of the continent, except Mexico and far northern Canada. According to TotallyTempo's comment above, they now live in British Columbia (south-west Canada), where I suspect they were either introduced or strayed and established themselves. The other two blue jays live west of the Rockies: the California Blue Jay and Steller's Jay. They are the same size as the Eastern Blue Jay, but differ in color, which shades from medium blue to very dark blue and nearly black. If my memory is correct, their heads are the darkest part of their bodies. Steller's Jay sports a blue to blue-black crest on the top of its head. The California Blue Jay has no crest. Both of these western blue jays are quieter and less agressive than their eastern cousin but live just as comfortably near humans.
- Not quite. This is the reason we have capitalization in bird names. The bird dealt with here is THE Blue Jay. There are literally hundreds of "blue" jays all across the Americas, and arguably the scrub-jays are also a kind of "blue jay". —Preceding unsigned comment added by Dysmorodrepanis ( talk • contribs) 11:43, 15 February 2008 (UTC)
Mexico's native jay is the Green Jay, which ranges from the southern-most tip of Texas south to Bolivia. I've never seen one except in a photo, which pictures a large and stunningly beautiful bird.

I would like to add a sentence or two about the blue jay's habit of doing a rather good imitation of a hawk call. I am looking up some references on it right now - both in print and on the 'net. This is something that I have witnessed dozens of times myself - although the first time I thought I was going crazy. If you are unfamiliar with this phenomenon - check out this google search.

IIRC BJs can be divided into "plunderers" and "non-plunderers" - the former steal from other BJ caches, the latter do not. When "plunderers" cache food, they go at great lengths to make sure that no other BJs observe them; sometimes they move around for prolonged time with food in beak, without eating it, if they cannot avoid conspecifics. "Non-plunderers" seem blissfully unawares of who obsrves them caching. This indicates that not only do they have individual personalities, but are actively aware of this fact, have a concept of "self" vs "others", and can reflect and abstract from their activities to those of others; they are thus capable of basic logical thought. Not bad for a teaspoonful of brains. Might be different NAmerican jay species though. I think the study was published in Science, Nature or PNAS in 2007, possibly in 2006.

Has anyone ever seen a blue jay employ the let-a-car-crack-a-nut trick crows have been known to use? Because I have.
"The Blue Jay (Cyanocitta cristata) is the morst feared force in the bird kingdom". I fear this is a somewhat ambiguous claim. It is unclear who, what or how it is feared. Some elaboration would be helpful here. —Preceding unsigned comment added by 69.250.53.6 ( talk) 16:00, 29 June 2008 (UTC)

The description says that blue jays have a prounounced crest on the head and the map shows them only living on the east cost. But Western Scrub-jays are blue jays living on the westcost and have no such crest. Could someone broaden the article? -- penubag ( talk) 02:21, 10 January 2010 (UTC)
- Blue Jay, capitalized, is a different species of jay from the Western Scrub-jay. The Western Scrub-jay may be a blue jay, but it is not a Blue Jay. A great reason as to why bird names should be capitalized.

- There is no reason to capitalize this bird's name unless we want Wikipedia to look like it's written by modern Americans who have no idea what a proper noun is. It'd be nice to see someone invested in this article calm down the over-capitalization here. I have long since given up trying to coach my fellow editors in English.

This species is not sexually dimorphic.
The article states that the name 'blue jay' "derives from its noisy, garrulous nature.[3]" I know this is cited, but even so, it is incorrect. The blue jay was so-named by early settlers to the US because of its resemblance to the Eurasian jay (Garrulus glandarius), another corvid. The Eusrasian jay, or just 'jay' as it was known by the settlers, is a noisy, garrulous and inquisitive bird. The settlers often named the birds they came across in the new continent after familiar birds from home, such as the robin - the Eurasian robin is a small red-breasted bird and the American robin was named after it because of its red breast. There are many other examples. It seems extraordinary that the etymology of the blue jay's name is not given correctly here. 217.39.106.157 ( talk) 18:24, 26 June 2014 (UTC)
- You are probably correct but a reference is needed for support. Dger ( talk) 21:31, 26 June 2014 (UTC)
The beginning of the article states "The blue jay (Cyanocitta cristata), (Chara Azul), or (Geai Bleu)...," which appears to be treating the French and Spanish translations the same way as its scientific name. It could be taken as incorrectly implying that Cyanocitta cristata is simply a name for the Blue Jay in another language. I suggest that, to remove this potentially confusing format, either the Spanish and French translations of Blue Jay be removed, or at least not referred to in the same manner as the scientific name.
