Tobacco Nectar

 

Anna's Hummingbird & Tobacco Flowers, Middle Lake

Apparently there's a trace amount of nicotine in the nectar of tobacco flowers. Thinking about animals that could benefit from a stimulant (I'm looking at you, koala bears), hummingbirds don't even make the list.

I didn't know the plant was tobacco (possibly Nicotiana tomentosa) as I watched several hummingbirds bickering over the flowers this morning. I'd have looked it up on the spot if I hadn't accidentally left my phone (plus money clip of cash and cards, and a pair of reading glasses) in a fanny pack at home. If I'd known, I'd have snagged a leaf or two to dry and burn, just to see what it smells like. (I quit smoking cigarettes thirty-eight years ago, which is probably why I'm cancer-free and can still go for walks and bike rides without an oxygen tank.)

Looking for somewhere new to go today, I rode out to Lake Merced to see if I could spot a rare bird recently reported in the area. Not only did I not find the rare bird, I wondered how anyone had spotted it in that location -- in a strip of plants and garbage along a canal next to the Olympic Club golf course.


A few Northern Yellow Warblers worked the tree line adjacent to the canal and golf course.

Over at Lake Merced's concrete bridge I was greeted by another bird I hadn't realized we hosted in San Francisco -- a grackle.

There are signs asking people not to feed the wildlife, but this guy was quite comfortable around people.

I figured the Western grebe on the right was a youngster since it seemed to be begging from the other bird.


Biking back along the coast via the Great Highway Extension, I thought I saw whale spouts. Only when I pointed my lens out to sea did I see that the splashes were from diving pelicans.

Despite the profusion of tobacco flowers, the hummers also took advantage of the adjacent eucalyptus.

It's nice to be able to get your nectar reward without needing to hover.
