Looks like flower buds in with the leaf buds in your photo. Post photos as this develops. It definitely could be in genus Prunus, hence the guess above, Prunus cerasifera, by
@Woocash is a good one. I have never seen an Amelanchier (service berry or shadblow, Juneberry or a dozen other common names) with pigmented foliage, but that does not mean their are none, just means I haven't seen one with pigmented foliage. To the best of my knowledge, all Amelanchier have white flowers.
So if flowers are pink or have a pink flush, and the foliage is pigmented, it is most likely Prunus cerasifera, sometimes called Sand Cherry. It makes a decent bonsai, has been used in both Europe and North America.
Nice find, keep posting photos.
