The Dude,Bandit and the Green Guys

Jack and I have two Hummingbird feeders on the patio. Every evening we relax with a glass of wine to watch them. They can be quite entertaining. We have named several of them....the major players are The Dude, Bandit,Little Green Guy and Big Green Guy (although we think the green ones are female).  There are at least 5 different ones that we can distinguish on the feeders.The Dude has been around for at least three years and has a beautiful purple head. He used to be the main man on the feeder,always chasing off intruders,but it looks like this year the green ladies have taken over and are chasing him away every night. I found some interesting facts about Hummingbirds:

• Hummingbirds are found only in the Americas.
  They are unknown in the Eastern Hemisphere. With 343 species, hummingbirds make
  up the Western Hemisphere's second largest family of birds.
• Hummingbirds require lots of energy. They have the fastest wing beats of any
  bird and their hearts beat up to 1,260 beats per minute.
• A Hummingbird's flight speed can average 25-30 mph, and can dive up to 60
  mph.
• In their non stop quest for fuel, Hummingbirds may visit 1,000 flower per
  day. For protein, hummingbirds eat spiders and strain gnats from mid-air. They
  will pull insects out of spiderwebs including the spider itself. Sapsucker holes
  are a double treat, netting both insects and sap!
• Many species that migrate to the U.S. travel impressive distances. Many
  ruby-throats make a 2,000 mile journey between Canada and Panama. The trip
  includes a non-stop, 500 mile flight over the Gulf of Mexico.
• Hummingbirds are very territorial and will aggressively protect nectar
  sources especially when migrating. It is important to have several feeders, out
  of sight of each other, to prevent one hummingbird from dominating your feeders.
  
• Hummingbirds have a unique way of keeping warm or conserving their energy -
  at night, or any time they cannot get enough food to fuel themselves - they go
  into torpor - a state in which their metabolic rate is only one-fifteenth that
  of normal sleep.
• A hummingbird can rotate each of its wings in a circle, allowing them to be
  the only bird which can fly forwards, backwards, up, down, sideways or sit in
  sheer space. To hover, hummingbirds move their wings forward and backward in a
  repeated figure eight, much like the arms of a swimmer treading water.
  
• Hummingbirds do not mate for life - the female raises the young on her own.
  
• Hummingbirds can live a decade or more in the wild.
