Aggressive hummingbirds

A couple of male Anna's Hummingbirds that were loudly chirping and occasionally getting up to chase each other:

The rival, probably a molting juvenile

Tiny guardian

I inadvertently walked under this hummingbird's nest, and was greeted with a flurry of angry chirps. 

Pink and sparkly

Tiny beaky babies

A series of photos taken this April and May, showing the development of two minuscule baby hummingbirds: 

Mom

Look closely

Just fledged

Possibly one of the babies, a few days later;
it was making the tiniest squeaking noise I have ever heard

New brood

The hummingbird that built a tiny nest in late January and had two babies successfully fledge in early March has returned to the nest for another brood-- and here is one of her new babies:

Hatchlings

Latest photo from the hummingbird nest-- two little fuzzy babies:

Eggs

Mar. 9: after being out of town for three days,
 I came back to find the hummingbird's nest looking nearly finished!

Mar. 10: taken while standing awkwardly on a stepladder,
camera held up over the nest, angry mother bird buzzing at me...

Mar. 11: the second egg has been laid!
(Two eggs is the almost universal brood size for hummingbirds)

Construction

In a tangled side-yard, another nest!

The little builder at work

 

Liftoff 2

The second juvenile hummingbird has taken off from the nest!

Following in the footsteps (or rather, wingbeats) of the elder

Licking leaves (in pursuit of dewdrops or tiny bugs?)

Abuzz

The youngster seems to be venturing from branch to branch in short hops

A clearer shot

Liftoff

The elder baby is now out of the nest!

The younger one now has the nest to itself...

Though it's also eager to take flight

On edge

The bigger hummingbird baby has taken to perching on the edge of the nest, testing its wings:

Mar. 1, buzz buzz!

Mar. 1, bold adventurer and scruffy younger sibling

Mar 2, after sleeping in the nest all night, it's time for...

...another flying attempt!
