Multiple Bird Species Share the Same Space (3 or more species)

I have always wondered:  Do birds of different species share space?  If yes, how many kinds?

What happens when they all want to eat the same food?

It turns out they can share in a very peaceful, non-interruptive manner.  See the pics below:

Finch on the left, hummingbird on the left:

Might be hard to see...Finch on the left...Chickadee on the right:

The example below is perfect:

Hummingbird on the left, Finch in the middle, and chickadee on the right (bottom).

2 finches on the left (male and female) and one chickadee on the bottom:

This one might be hard to see, but flying green hummingbird on the left (arrow), and Finches on the right:

Finch on the left and hummingbird on the right (door hanging feeder):

See arrows below:  2 finches on the top and one chickadee below them on the flower.

The chickadees like to hop fast everywhere.  The other birds will have to pick their places.

Chickadees on the left and right, finch on the tree branch above:

Sometimes, I find they will actually sit and observe each other in order to make the next moves.

Hummingbirds are quite curious and they will fly around the other birds to observe.

 Hummingbirds, finches, and chickadees are all cute and lovely.  I kind of wish that they wouldn't poo so much on my railing then.  LOL.  (I will have to clean up.)
