Help identify this berry tree.

I searched for images of the tree in google http://www.tamenobu.com/images/berrytree.JPG but the poster didn’t know what the tree was either.

I have several of these outside my office window and the robins that feeding off of them this morning are crashing into my window because of the reflections of the trees in the mirrored glass. One actually just broke his neck and is laying outside. Boy is fat from eating berries. What are these things? They seem to be driving the birds nuts.

They look like Mountain Ash/Rowan Tree fruit.

Hmmm, interesting but those seem more tightly clumped than what I am seeing and in the picture I linked. I’m suprised they don’t have a more local/commen name.

I’m pretty sure it’s not a rowan. It looks more like hawthorn to me.

No thorns to be seen, apart from that I got nothing

Good point, maybe it is a well eaten rowan tree.

Any chance you could post another picture at higher resolution? The one you provided is nice & artistic, but there’s not much detail to go on given how little of the picture is well in focus. My guess is something in the apple family (perhaps some kind of crabapple?) or the Rose family, but beyond that it’s really hard to tell.

My first respose was some variety of crab apple when I saw the photo, but without knowing what size the fruits are it’s very hard to tell.

Birds often get drunk off of fermented crab apples, and since they’re common landscape plants, they often kill themselves smashing into windows.

ETA: Dammit, MikeS beat me to it!

Where are you located?

Here are some pictures of the actual tree:

Definitly not apples. Smaller than cherries.
And I don’t know why the hyperlink button isn’t asking me for text to input instead of just showing the link.

From the leaves, it definitely isn’t a rowan.

Would you mind a closer photo of the bark and twig with leaves? Furthermore, did it have beautiful pink flowers in the spring?

It did have pretty flowers in the spring. I recall them being more white than pink but can’t be sure now.

Cotoneaster - No
Hawthorne - No
Flowering Crab - Yes

I don’t know what variety of flowering crab, but the fruit distribution is not a clump like a cotoneaster. The leaf structure is like a flowering crab and not like a hawthorn. Flowering crabs come in enough varieties that one with this trees habits falls into the range. It looks like a flowering crab with small fruits that are just turning to the red stage. Now if tonight you pick on and examine it, you can know for sure.
