Hi , I have a couple of large shrubs or small sized trees growing behind the house that I can't ID. First 2 photos are of the larger one which is about 9-10ft tall currently. The flowers started out as tight little clusters and have spread out. 3rd photo I thought might be a salmon berry bush but doesn't look quite like it. Has some thorns on the lower stalks and seems like some kind of berry bush.
The first are Sambuca caerulea if fruit is blue....(Elderberry) and the second is a Salmon berry I believe... (Rubus spectibillis)
Pacific red elder and salmonberry - two abundant local natives. The elder produces fruits that are most often red but some places have numerous purple-fruited individuals. Occasional specimens may bear orange or yellow fruits. One I spotted up the road from me one year was sporting canary yellow fruits. After I asked at the door for cuttings and seeds (and was allowed to collect these) the specimen disappeared. Seedlings of it produced red fruits.
