The fledgling was struggling to stay alive, its eyes were closed and it could barely open its beak for feeding. It didn't seem possible that the baby could survive. But miracles can come in tiny packages. After being warmed up and fed special protein nectar for a few hours, the baby suddenly revived and began buzzing around in its basket. Within a few days, it was flying and eating "on the wing."

One week later, the little bird was transferred to an outside enclosure abundant with blooming nectar-rich flowers and hummer feeders. For another week before the bird was released, it acclimated to outdoor weather and could be seen hovering from blossom to blossom. Zukowski was thrilled to have the healthy and vibrant hummingbird returned to her garden. The joyful occasion was shared by her three grandchildren.

This iridescent bird is the most common hummingbird in the Bay Area. Males have a scarlet head and throat, while the female's head is green with red specks at the throat. Anna's is non-migratory and is a familiar sight in our area all year round. It's the only species of hummingbird that nests in just one state - California.

While it may seem that hummingbirds derive nutrition solely from the nectars of flowers and feeders, a large part of their diet is actually protein-rich spiders and insects. Hummingbirds must eat every 10-15 minutes since they have the highest metabolism of any warm-blooded animal.

They normally beat their wings 50-70 times a second, but in rapid flight, it can be as fast as 200 times a second. They conserve their energy at night by deep sleep, called torpor, with their heart slowing and their temperature dropping.

If you want to enjoy the beauty and grace of what John James Audubon called "a glittering fragment of the rainbow" here are a few tips:

n Set up an easily-cleanable hummingbird feeder in a shady spot.

n Replace the nectar (one part sugar - don't use honey - to four parts water) twice a week.

n Plant colorful, tubular flowers such as salvia, columbine, fuchsia and winter-flowering plants, such as Kniphofia and Scottish Heath, making your garden a veritable hummingbird magnet and backyard rainbow, come rain or shine. If you're diligent and reliable, not only will your hummingbirds be gracing your garden year round, but may also raise the next generation of hummers in your trees.
