Leucistic Hummingbird

 

Leucistic Anna's Hummingbird, San Francisco Presidio

I ran into several other folks hoping to spot the leucistic hummingbird reported near One Letterman Drive. After waiting a while for it to show up I decided to stroll around the grounds to look for likely nectar-producing flowers where the hummer might be holed up. There were plenty of regular Anna's hummingbirds in attendance, but I searched in vain for the white one.

I'd been talking with another photographer when I looked toward the bare-branched tree in which the hummer has previously been seen and was excited to spot a white blotch on the tree that could be only one thing. I told the other photographer it was there, and we made a bee-line for it. The unusual snow-white bird didn't stay long, but I think everyone was happy to have fired off a few frames. I know I was.

It was after noon by the time I got back on my bike to head home, making a brief stop at El Polin Spring despite my stomach rumbling for lunch. El Polin was full of birds, and the sun was coming out, but I needed to get going. 

It turned out the rain really arrived as forecast the other day, and it looks like much more is in store. I see the sun shining through our living room window this afternoon and know I'd better enjoy it while it lasts.


I spotted this red-shouldered hawk as I coasted down Pacific Avenue adjacent to the Presidio. It was hanging out on the retaining wall and pouncing into the leaves on the ground below.


The hawk did this several times but never seemed to catch anything.


Caught with its nictitating membrane shut over its eye.


After giving up on the leaf litter, the hawk casually swooped across the road and landed on a low branch.


I could hardly have asked for a more picturesque branch for it to pose on.


I spotted some shaggy parasol mushrooms (Chlorophyllum brunneum) while poking around near the tree where the white hummer would later show up. Note the likely slug-munched square rasped from the cap.


According to California Mushrooms, they are "edible and choice," although some people are allergic to them.

An orange-crowned warbler also snagged something. The background is a building next to the tree.

The White Hummer In Its Tree


Apparently leucistic hummers can be even whiter than this.


Some pygmy nuthatches were working the bottlebrush flowers along with several other bird species (including two or three regular-colored hummingbirds).

I went back to the tree in time to catch a second sighting of the leucistic hummingbird.


A second, ordinary, hummingbird perched in the same tree, sending this one deeper into cover.
