Hummingbirds

The nights are around 50F now, and the birds are packing on fat for migration.  There have been a lot of hummingbirds in the garden, but they like to feed at dusk.

I took dozens of low light hummingbird shots last week, and they’re all blurry.  Each of these birds are speedy fast, and jewel-like in their beauty.

According to Wikipedia, a hummingbird that survives its first year is likely to live a decade or more.

How could a little bird live so long in such a dangerous world?  

Beauty, speed, keen mental maps and luck hardly seem enough to keep such ethereal beings among us.   

Bird feeding

After I saw a flicker regurgitate food into a grown chick’s beak, I started to see lots of birds doing it.

This evening grosbeak is giving its chick a second meal: the parent filled up at the birdfeeder, regurgitated the food into a chick perched on an aspen, and flew back to the birdfeeder to stock up again.  I got my camera and waited, along with the chick, for the parent to provide a second helping, shown above. 

A turkey vulture

At first we thought that a golden eagle was perched on the debris pile near the ditch,

but instead it was a turkey vulture, or buzzard.  Wikipedia says that, like storks, these birds often defecate on their own legs to cool themselves through the evaporation of the water in the feces and/or urine, a process known as urohidrosis.  See those white streaks on his feet? It’s uric acid!  Eeeeeew!

It looks like part of a rat is hanging from its beak.  I didn’t get a clear shot, but

avulture.jpg

it looks as though this giant bird took its rat along when he flew down the creek.

The turkey vulture isn’t the only scavenger that patrols this debris pile: Gracie finds dead animals here as well.  In the last three days, she has brought home a duck dripping with maggots, a squirrel missing most (but not all) of its guts, and 3/4 of a magpie.  She has many charming traits, but her affection for rotting corpses is not one of them. 

Mothers and Daughters

This flicker was so pretty that I took a picture of her on the feeder.  I assumed that this highly colored bird was a male, but learned later that male red-shafted flickers have a red, teardrop-shaped mustache, while the females have a less distinct brown mustache.

She hopped onto a nearby boulder, and another flicker flew over and sat next to her.  Quick as can be, Mom started regurgitating seed into her grown daughter’s beak.

Here the grown nestling has her eyes shut in bliss, remembering back to the days she didn’t have to take care of herself. 

aflicker2.jpg

Here she’s wide-eyed,

 and here you can actually see the flow of birdseed from mother to daughter.

Thanks, Mom, that was great. 

A robin bobbin’ in winter

A flock of robins is wintering in an orchard down the road. 

arobin21.jpg

A few of them regularly drop by to forage on a steep, south-facing slope near my office.  I thought it was a sign of global warning that they didn’t fly south, but instead

robins live here year round.  I had no idea!

arobin11.jpg

Here’s a photo of a bobbing robin, with both feet off the ground. 
 

stotting1.jpg

Here’s a picture of a stotting mule deer, all four feet off the ground.  (This is my edit of a photo from the biology department of the University of Regina in Canada).

Bobbing is a gerund of bob, and like many old words ’bob’ has many meanings.  In the robin’s case, it’s 

bob –verb (used with object)

2. to move quickly down and up: to bob the head
Origin:
1400–50; late Middle English bobben. )

 

The mule deer’s stot is from the same root as stutter.

stot –noun

1. a springing gait of certain bovids, as gazelles and antelopes, used esp. when running in alarm from a predator 

verb used without object

2. to run with such a gait
Origin:
special use of Scots, N England dial. stot bound, go by leaps, bounce; perh. akin to ME stuten to stutter 

 

It takes a special word to leap straight up in the air. 

Gravity and grave behavior keep us moored to earth, while all around us creatures are stotting and bobbing.  There’s a lesson about joy here, but I can’t put my finger on it.

Life without a Dog

It can be hard to maintain a birdfeeder here, because the deer will empty it any night you forget to bring it in.   We haven’t had one up in a while, but after Jessie died it seemed like no trouble at all to start feeding the birds again.

aduck2.jpg

The littlest birds take the seed neatly from the feeder.  Bigger birds like this flicker hang on the bottom of the feeder and spill seed on the snow where the magpies (too big for the feeder) can get it.  I started giving the birds table scraps, and trimmings that would go to the compost pile in the summer.  They were eating the two-day-old salad in the fridge that isn’t quite ready to toss.    Everything was fine until the ducks heard about it. 

aduck3.jpg

The entire flock of ducks marched in a single line from their hiding place on the ditch to a clearing in the forest.  I enlarged this photo, and counted forty (!!) wild mallards assembling for an assault on the birdfeeder.  They marched from the forest to the feeder in two groups: one approached from the left, and the other hooked around and came at the feeder from the right.   

aduck41.jpg

It wasn’t a successful visit.  The smaller birds don’t mind sharing, but there are too many ducks for the birdfeeder.  And there were other problems as well.  The feeder is too exposed for mallards.  Although Jessie is gone, they remember her without affection.  From the duck’s point of view, there wasn’t enough food to warrant the risk, and they haven’t returned.   

aduck1.jpg

Except for this girl, who waddles over to dabble at seeds on the snow almost every day.  

 

(The birds don’t tolerate me at all, so these photos are taken through a glass door.)

The Secret Ducklings

A few mallard ducks spent the summer in our part of the irrigation ditch.  Those ducks had to avoid the neighborhood cats, bobcats, raccoons, skunks and coyotes.  Their survival depended on them keeping a low profile, so I left them strictly alone.

aduck1.jpg

Bob told me this morning that they raised a few nests of ducklings while I was looking the other way.  There are now more than a dozen ducks hiding in the ditch, but they’re shy (here I’m spying on them behind a full set of greenery.)

aduck3.jpg

This is one of the ducklings, a newly mature male mallard whose head and neck feathers are just coming in.

aduck2.jpg

The rest of the flock is just around a bend.  I’m hiding behind grasses here, and as soon as they see me they swim away

and fly away.   

 

A slime mold and a black-capped chickadee

Here’s a black-capped chickadee

achickadee11.jpg

eating sunflower seeds.  I had high hopes for this photo, but it didn’t quite do it (I’d ask my photographer guru, but he’s off teaching a wildlife photography seminar in Yellowstone.) 

 achickadee21.jpg

Perhaps this version is better?  It’s an almost-good photo of a bird we’ve all seen a zillion times.

Here’s a photo of a slime mold.  Can you see it glisten?  See how much this species looks like snot?  Slime mold was classifed as a fungi until recently, when it was discovered through DNA analysis that it isn’t.  This multicellular version is a myxomycetes, the only slime molds that are large enough to see.  (That’s myxo - a combining form meaning “mucus” or “slime” and mycetes - a combining form meaning “mushrooms, fungi”. ) 

In a plasmodial slime mold like the one above, many individual cells are attached to each other forming one gigantic cell membrane. This “supercell” is a bag of cytoplasm that contains thousands of individual nuclei.  It’s a plantlike creature that moves.  It is supercool.

A so-so photo of a regular old chickadee, or an in-focus photo of the rare and elusive slime mold?  I couldn’t decide, so I posted both.  

A robin catches a worm

There was a big flock of robins gathered out back for their upcoming migration.  They were having a wormfest, catching and eating worms one after the other.

arobin3.jpg

Here’s a handsome robin, thinking about a worm.  It hears a worm,

arobin2.jpg

 it sees the worm, and

arobin1.jpg

grabs and swallows it. 

Hummingbirds in flight

The hummingbirds are very active these days, preparing for their migration south.

ahummer11.jpg

 They beat their wings in a figure eight, which allows them to hover.

Th hummingbird is a New World bird, absent from Europe and Africa.  There are many Native American legends about the hummer.   

My favorite is the Aztec legend that tells of the time when the god of music and poetry took the form of a hummingbird.  He descended into the underworld to make love with a goddess, who then gave birth to the first flower.
