Predator

The circle of life in a Scottish graveyard: 

European robin vs. earthworm 

Oriole nest

Mommy bird visiting

Three babies!

Seaside brunch for two

This gull was attempting, with little success, to break the shell of a still-squirming lobster: 

Then it began squawking (what looked and sounded like  a pair bonding call), attracting the attention of another gull. They bobbed their heads and squeaked at each other (as in the linked video), and then the newly arrived one began to attack the lobster:  

 And finally cracked the shell!

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

Red-Shouldered Hawk

Stalking on the ground like a dinosaur:

Snapping up beetles:

Carrying a leafy twig, perhaps planning a nest:

Spring babies

Ground Squirrels: 

Ravens: 

Great Horned Owl: 

Coral tree raven

They like to nibble on the flower petals.

Tiny guardian

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

Wind dancers

A white gull feather was drifting on the wind. Then a raven swooped to snap it up, dropped the feather, and caught it again: 

These two were dancing over the sea:

Whitecaps below:

Bitey babies

The baby cormorants are getting huge:

"Feed me!"

And they bite each other: 

"Hey, play nice!"

A tinier little one snuggling with its parent:
