Hummingbirds, Pollination and Knoxville's Hummingbird Festival

From flower to flower, hummingbirds accidently carry pollen from one blossom to another.  The pollen sticks to their beak and feathers, and if the flower they visit next happens to be the same species, pollination occurs. 
This series of images tells one story of how that pollination happens.  The red flowers are cardinal flower blossoms and the stigma which releases the flower's pollen sits in a perfect place to rub against the hummingbirds crown as it nectars the flower.

The hummers feathers and the stigma rub against each other, and as the hummer backs out of the flower, the stigma is stimulated to release its pollen, shooting it out as if from a faucet.  


Below, a layer of pale yellow pollen covers the top of the hummer's head, ready to pollinate the next flower visited.


Hummingbirds are fascinating for many reasons.  Next to size and speed, pollination and migration are two of the intriguing qualities of these tiny birds.  On August 24th, when fall migration is at its peak in Tennessee, the Knoxville Chapter of the Tennessee Ornithological Society is celebrating hummingbirds with the Wonder of Hummingbirds Festival featuring hummingbird banding demonstrations by master bander, Mark Armstrong. The festival will also include expert speakers on hummingbirds and other nature topics, nature related vendors, great food, and, of course, I will be there exhibiting art, so come by and visit!

  3. What fabulous photos, and I absolutely love your blog banner. I so wish I was in TN. I'd love to go to this festival. I adore hummingbirds and recently got a tattoo of one on my right shoulder. Murr sent me and I'm so glad she did.

For the Love of It...

...the sage sees heaven reflected in Nature as in a mirror, and he pursues this Art, not for the sake of gold or silver, but for the love of the knowledge which it reveals.

"There is a vitality, a life force, an energy, a quickening that is translated through you into action; and because there is only one of you in all time, this expression is unique. If you block it, it will never exist through any other medium and it will be lost. The world will not have it. You must keep that channel open. It is not for you to determine how good it is, nor how valuable. Nor how it compares with other expressions. It is for you to keep it yours, clearly and directly." ----the great dancer, Martha Graham
