Pacific Forktails


On Saturday the 29th, I had come home around 1:30 in the afternoon to see a crow dive-bombing something on the building behind mine. At first I thought it was another crow, maybe one with a particularly interesting bit of food, that was being harassed. Watching for a little while, I got the idea that the bombee was a little bigger than the crow, and that caused me to rush inside and get my camera and long lens. If something looks a lot like a crow, only bigger, it's probably a raven. I'd never seen a raven in my neighborhood before.

Once I got back outside with my camera, I found that the confrontation had moved from the building into the sky. There were, in fact, two ravens, and the crow seemed intent on bothering one of them in particular. Here's a shot showing both ravens and the crow; the ravens have their wings spread and the crow has his folded a bit, in a dive towards the bottom raven.

 

The species involved were our local ones, the Northwestern Crow and Common Raven. Soon they had flown far enough away that photography was futile, and I headed back inside.

I was only inside long enough to change my camera back to its macro configuration, though, and then I was back in the courtyard looking for subjects. I walked around our lagoon and soon saw a bug with very long antennae on one of the plants near a little bridge.

 
This insect is a Long-horned Caddisfly. Here's a more-closely cropped version; this guy's eyes really stick out from the side of his head.  
Those two shots used flash lighting; I was handholding the camera with flash and bracket. Here's another such shot, a fly on a nearby plant. For this photo, I was able to get closer to the insect with the camera, and consequently was able to get better detail.  

I haven't been able to figure out what type of fly that is.

On the other hand, a little bit of research sufficed for me to figure out that this damselfly is a female Pacific Forktail.

 
And this blue fellow is a male of the same species.  
Here's another male Pacific Forktail from a little later, showing a hint of green color on the bottom of the eyes and thorax.  
On the far side of the courtyard from where I live, I found some Gladiolas, and with the flash I was able to catch a Honeybee heading in towards them.  
I didn't find much else in the courtyard, so I headed to the outer side of the building. On some stairs there, I found a dead bug. A count of the legs (five or six on this side) told me that it wasn't an insect or a spider. This little critter belongs to the Isopod order (Isopoda), which is part of the Malacostracan class (Malacostraca). We commonly call 'em pillbugs or sowbugs or woodlice. Anyhow, the little bumps all over this fellow's back identify him as the very common Porcellio scaber.  

That did it for interesting subjects on Saturday; the weather hadn't been great and I had photojournal entries waiting to be put together back inside on my computer, so I didn't stay long outside.

Uncharacteristically short-winded,
Tom
