Are they the Annas?

I remember being *tuned* to cam that was on Anna’s nest in someone’s patio in Seattle .... watching the nest being prepared and the process of hatching. It was a joy to watch.

I haven’t seen that but their nests can be remarkable.

In the spring, I call up this hummie migration map ...and watch and wait for my beauties to arrive.

I don’t know if they have a migration map for you *westies*

Hot Tabasco: "God created every living species of life on this planet........."

Of course, evolution theory simply attempts to explain in natural terms how He did it.

Hot Tabasco: "If evolution occurred, it should have been in a singular direction but it didn't."

Your assertion is not supported by any evidence or theory I know of.
In fact, evolution has no fixed "direction", except that it does try to fill every available ecological niche, and it does tend -- long term -- to "complexify" DNA.
Species radiation results include: almost anywhere there are plants you will find herbivores adapted to eating them, and most places where herbivores feed, you will find carnivores adapted to catch & eat them.

Hot Tabasco: "Evolutionists tell us that all life began from a primordial soup but they can't tell us how and why there are literally millions of different species of bugs, birds, worms, animals, plants, microbes and germs that came out of that mud.............

Basic evolution theory does not say how life itself first arose on Earth, except to speculate about "primordial soup" and organic chemistry.
However, evolution theory certainly does describe the long-term process of speciation and radiation from common ancestors -- which produced the diversity of life we see today.

Hot Tabasco: "When you look at the diversity of birds, from penguins to condors to hummingbirds, each has their own unique characteristic that completely separates each from the other."

But every individual, you and me included, has unique DNA which distinguishes us from every other individual of our species.
This uniqueness has allowed law enforcement to convict criminals, and orphans to identify their biological parents.

However, amongst all humans, the percent of identical DNA is in the range of 99.9% and that means we can all interbreed successfully, under the right circumstances.
But the more that percentage of identical DNA falls, among related populations, the more difficult it is to interbreed, and so scientists identify categories of "breeds", "sub-species", "species", "genera", "families", etc.
In this case, each larger category designates increasing difficulty to interbreed, and therefore more distant relationships.

To pick just one example: DNA analysis shows that ancient pre-humans and Neanderthals occasionally did interbred.
That's because they had very similar DNA.
But the differences in DNA between humans and, say, chimpanzees is just too great to allow interbreeding.
So chimps belong to a separate biological genus.

Hot Tabasco: "This as well as all other info on hummers is theory............."

Of course, theory is how natural-science explains the world we can see, in terms of reasons which are not themselves observable.
Theory is as good as it gets in science.
