Cool Fall like weather today .. and rain on the way!!!

The Annas Hummingbirds go through a Summer moult ..  This adult male is getting some new feathers!

A young Annas male puffs up his feathers in the cool morning air... Birds have the ability to  add insulation quickly by fluffing up their feathers or relaxing them  and going for a more streamlined  look depending on the air temperature or if they want to appear larger and go on the defence of their territory.
