Spring is in the air, it is on the ground, and it is showing up on winter deciduous trees.

This cluster shows a still leafless Himalayan Birch (Betula alnoides) full of yellow catkins, the other taller trees are Himalayan Alder (Alnus nepalensis) which have new leaves & leaf buds. The dark evergreen trees are Tree Rhododendron (Rhododendron arboreum).

Genuinely sooner than I expected, I thought this was covered with snowpack yesterday, but maybe not?
