Tree species identification

Hello!

I'm attempting to get familiar with trees on our property which is in the Boreal forests of Estonia. So far I think I can identify birch, aspen, oak, and spotted alder.

We've got a stand where there are a lot of these (in the following winter photos) which I would love to know what they are.

Any ideas?

Bark only tree ID is tough...

I thought so. I might be able to get a dry leaf thats still stuck to a branch if it helps.

Ya any leaves, flowers, seeds (if any) would help.

I found this lone stranger frozen up high still attached. Soaked in water to soften it up for these shots. Any ideas?

and..

My guess from bark, leaf, and habit is some sort of poplar, perhaps a hybrid or a close relative of Populus balsamifera and P. trichocarpa in North America. If I'm correct, the buds should be a bit sticky, and likely aromatic when crushed.
