Random List: Winter Sound Effects

Sounds I hear only in Winter (and a couple I imagine):

• sleet rat-a-tat-tatting on the metal barn roof
• icicles shattering into oblivion after falling onto the walkway 
• boots punching through ice-crusted snow
• tv/radio droning on with school delays & closures
• cacophonous bird shrieks as they swarm seed-filled feeders
• full length zipper on snowsuit growling up and down
• heavy hush inside snow-covered greenhouse
• crackle of ice coated branches as they shiver in the wind
• hollow thump of snow plow knocking mailbox off post
• whir of electric meter spinning wildly
