One of a pair, which smacked into a window and flew around inside until ushered out. It sat on the tarmac recovering for a few minutes and then both of them flew around squawking before zipping into an open hangar to incite more ruckus.

(it's not attacking/being hit by the sign in the photo; it had perched on the end and was being gently tipped onto the ground)

Small-coned pine, South Lake Tahoe.

Leaves are around 5 cm, and cone is slightly shorter.

Needles are bundled in pairs.

This identifies a lodgepole pine, and the Sierra Nevada location gives the murrayana subspecies.
