A lot of you have more pictures and much more knowledge than I do about hummingbirds. All I've done is sit around with Lou's hummingbird helmet on in Wisconsin, which netted no birds, and take the picture below in Big Sur. What kind is this, please? I knew but forgot. There were gazillions of them.

I'm leaving on a trip tomorrow, and I've already packed my "Western" field guide away, so I'm no help with your bird.  But I'll add my own favorite backyard hummingbird photo (Ruby-throated Hummingbird).

I have posted this photo before on this forum...but the story is worth a re-run!  This is a female Hooded Warbler.  We met her as we were hiking in the Great Smoky Mountain National Park.  We were tripping merrily down the trail when a rather clueless fledgling came hopping up the trail directly at us.  I think it hadn't yet learned to avoid humans, and was friendly and curious like most young things.  Mother Hooded Warbler got concerned about her goofy youngster, flew down in front of us and tried the "broken wing" routine to try and lure us away from her offspring.  Very cute.  We stayed long enough to snap this picture and then gave them some space.  Happily, the fledgling didn't try to follow us!

I also recommend reading the wikipedia article on the Hoopoe, especially the "relationship to humans" section, which cites mentions of the beast in the Quran and Ovid's Metamorphoses.

The "relationship to humans" section was interesting...but the predator defense tactics, even more so!  Secreting a substance that smells like rotting meat that they rub into their feathers, shooting feces (and I thought only primates did that), and hissing like snake!  Pretty cool bird, but I wouldn't want to get on his bad side.

OK...I'll see your weird looking bird and raise you.

This is a Hoatzin, another amazonian bird.  I took both photos in Peru, at the Tambopata Reserve.  Like the Hoopoe, you wouldn't want to eat the Hoatzin, unless you enjoy a bird with a "disagreeable, manure-like odor"  (Wikipedia http://en.wikipedia.org/wiki/Hoatzin).

You might want to read the full wikipedia article; Hoatzins are unique in several ways!

The first photo is the halfway decent one; the second one was blurry, but I thought turned out rather interesting in spite of the blur (or maybe because of the blur).

This is great - LOOK at all these birds!!!

I am so enjoying this!  So many birds I'd never seen before! And we're only at G!      

We are only at G, but I'm finding, as I dig through my bird photos, that 65% of my photos were of birds that start with B, and 35% with G...so my volume ought to slow down pretty significantly!  OK...that's a slight exaggeration, and I'm sure there will be a few more "big" letters, but I really have gone through a large percentage of my photos already.

And another bird from the Galapagos...the Galapagos Dove.  Many birds in the Galapagos live nowhere else; and many live only on one of the islands.  The islands are isolated enough from the mainland, and from each other, that the wildlife species that colonized them adapted to the unique conditions of each island and developed into unique species.  This dove is spectacularly beautiful, even if my photo doesn't do it justice.

G is for Galapagos Hawk -- we took this photo, obviously, in the Galapagos, of one of the few non-introduced predators on the islands.

Our guide said this one was hanging out on the ground hunting for baby iguanas (at least he doesn't eat vinegar & salt potato chips).

G is also for Gilded Barbet.  This is another photo I took in Amazonian Peru, from the top of a canopy tower.

This is a Grey Hawk...though they can be seen in the Southwestern United States, I took this photo in the wilds of the Peruvian Amazon rain forest...he's very pale and pretty.  His favorite prey items are lizards and snakes.

G is for Grosbeak...and I've posted two species.

The first is a Black-headed Grosbeak, taken in Southeast Arizona (the bird in the upper part is a very blurry Western Tanager).

The second is a Rose-breasted Grosbeak, taken here in Kentucky...we only see them during migration, but it's always exciting when they're passing through!  (the bonus is the Northern Cardinal).

And this is a Green Heron, taken here in Louisville...no exotic travel necessary!

G is for Gray Jay.  I've attached two samples:

The first we took in Yellowstone in autumn (though a friendly park employee told us that they actually only have two seasons in Yellowstone:  winter, and July)

We took the second photo in Rocky Mountain National Park in Colorado, pre-digital.

Gray Jays are among our favorite mountain birds; they're fun to watch, and fairly laid back around humans.

And to contrast with these Ginormous G birds we've been posting, here's a Golden-crowned Kinglet.  I took this photo in Cape May in October...this little migrant was really hungry, so focused on food that he wasn't particularly attentive to the humans watching him.  Sorry for the blur, but kinglets aren't known for being still...

since we're on GREAT, here's a GHO I drew. At least it was a GHO when I started drawing. Then it got grumpy.

I love the drawing!  I'll contribute two photos of Great Horned Owls as well.  The first is from my birding vacation in Southeast Arizona.  I took the second photo of a fledgling (or at least one who has "branched"), this past May at Ottawa National Wildlife Refuge in Ohio.

G is also for Golden Eagle.  We took these two photos when our local raptor rehabilitation group invited us to a release.  This immature bird was found on the ground, very weak, and the vets discovered it was suffering from lead poisoning.  It was successfully treated, and we got to watch the release!

A few Golden Eagles winter in Kentucky, as this one was, though they're much less common than wintering Bald Eagles.
