April 26th 2020 ... My 1st visit to this Anna's Hummingbird nest with "Holly" and her 2 kids  
Male Annas hummingbird above showing a sequence of 4 slides.
The males perform a courtship dive, but first sit in a tree and observe a female, then fly up to quite a height, hover and watch the female, then suddenly turn downward and fly at great speed right past  her!
The 5th image shows him turned vertically and is the moment before the decent.   (At that point he zooms to quickly for me to follow.)  At the bottom of the dive as he pulls up to avoid crashing, the tail is lifted sharply and a squelching chirp is heard caused from wind hitting the tail.  I have read that sound can be heard up to 100 meters away.
Hummingbirds are simply amazing tiny birds! 
January 11th 2019 ... I dubbed this male Anna's Hummingbird the Deck Boss as he is king of the deck feeders as I type... 
A dazzling little Rufous Hummingbird as seen on the 1st string of returning birds from Wintering in S Mexico (March 18th) 
February 6th 2017 ... Anna's female (above) and male (below) contemplate warmer days ahead.
