What type of trees are these?

[Stephen Tashiro]

What type of trees are the two trees in the photo (center tree and nearer tree to the left). They develop a prolific amount of berries that turn a pinkish red before the berries fall. I never see birds eating the berries.

Pistacia (like pistacio but that is another variant).
Is also found in the middle east...called a turpentine tree
(maybe that why is the birds don't eat the berries ....turpentine ....blech!!! :D)

Not to be confused with the pistache tree whose fruit is edible.
Modesto is replacing Modesto ash street tress with Chinese pistache trees. Modesto ash only live around 75 years before they rot.

Yes... there was something said about the tree in question that the fruit was not palatable to humans.... or I guess to birds either according to the OP.

I’ve only used it once or twice so I don’t know how comprehensive it is. It’s a free app called “Seek” from iNaturalist that can identify plants, birds, insects and many other creatures and vegetation.
