Quercus lyrata maybe, although it is difficult to see the shape of the leaves well. Where are you located?

might help to know where you are.. and if the photo is current .. in other words.. is the plant evergreen??

a scale or size on the leaf might also help ...

Sorry, I forgot to add zone 8 Central Texas!

right back at you. i now see the TX garden .. go figure .. ken

Reminds me of Q. lyrata also.

Q. lyrata would be rare in Central Texas. Our most common species of white oak is post oak (Q. stellata). Bur oak (Q. macrocarpa) is also possible, but distinguishing between the two isn't easy based on the leaves in the photo, in part because the leaves of post oak exhibit a high degree of variability. Bur oak produces much larger acorns.

Been over half a century since I lived in Ok/Ar/Tx area so memory is a bit old. Certainly in white-oak group but finer distinction eludes me.

Looks like pointy tips on the lobes. If so, a red/black-type oak.

Agree with wantonamara and bengz6wetmd that your oak is likely Quercus shumardii (Shumard's Oak), Quercus buckleyi (Texas Red Oak), or maybe Quercus falcata (Southern Red Oak), based on location and the deep lobes with bristle tips.

Q falcata is an East Texas tree. Q Shumardi is planted to Austin , but does not like the shallow soils of the hills in the west unless you have some deep bottom land or brought in fertile fill. Q. Buckleyii likes the shallow soils. Pure shumardii is planted in developments out here. But it is hard to tell sometimes which is which between those two species out in my hills since they are not pure in the native stands in and around western Travis county.

I don't know where you are in Central Texas. It looks flat so maybe you are further east. Squirrels don't go that far in their travels so look around for trees that might be the parent and see if the owner knows the species.

Brazos County Texas - adding a new photo for size and better definition of the leaf. Thanks for helping!

The other oak trees in my yard are previous owner planted live oaks and water oaks with much more rounded leaves. My neighbor has a forest of native oaks in his yard but has no clue what types. Other neighbors know less about trees than I do. This one intrigued me because it's leaves are currently somewhat red and all my other oaks leaves are either green or yellowish. This one is very pretty!

With your location , I would guess a Shumard Oak But there are many more Texas Oaks. Here is a site (Aggie tree native tree list) that list a few. I would cross reference it with Range maps on Plants.usda.gov. If you slide the bar up 2 clicks it will show the county distribution. Are you in acid soil or alkaline. Also bear in mind that leaf shape can be different in Juvenile trees , or so I have observed. I am no botanist, just someone who was the woods.
