Phase variation in red tailed hawks

Image
Red tailed hawk, Kelowna At first, I thought it might be a Cooper's hawk.  The reddish-brown chest and light ventral tail feathers were misleading at distance without magnification, but when I brought my camera to bear, the identification became clear.  What impressed me, once again, was the variation in feathering of these magnificent birds. Below is a comparison of different red tailed hawks I have photographed; three photos from the past compared to the one I photographed yesterday.  Of the three, the above photo most closely corresponds to the medium phase, although I think its head is more like the dark variation. Three different phase variations of red tailed hawks that I have photographed. The one on the left is often called Krider's red tailed hawk, it is more common on the plains, although I photographed this one in Kelowna a few years ago.  Notice that all the hawks have one feature in common - the belly band - which is a distinguishing attribute for the sp...

Cinnamon teal - not your average brown duck

Image
Photographed April 4 at Carney Pond in Kelowna.  First time I have seen this species. One of the nice things about using bird field guides is that you get to peruse all kinds of birds, not just the one species you are interested in.  This has the advantage of allowing yourself to become familiar with a variety of species, not just one in particular.  Although I have never seen a cinnamon teal before, I knew immediately that it was one because I have seen many images of it when scouring through my bird identification guides. The male duck's colour is somewhat unique in that the shade of brown it sports is almost orange.  Calling it an orange duck wouldn't really work, though, because there is a particular dinner dish with that name (although it is worded in French).  And the name "brown duck" does it such a disservice, although the female could be equipped with that moniker.  I have a photo of the pair below. Male and female cinnamon teal ducks Cinnamon teal...

Tawny mining bee - Dilworth Mountain Park - Kelowna

Image
One of many hundreds of mining bees exploring the paths at the park.  They rarely landed. It was a sunny, bright spring day in Kelowna.  My daughter was visiting and walking the dog sounded like a fine idea.  We quite like the park on Dilworth Mountain.  It provides some excellent views of the city an Okanagan Lake.  While we were following the paths, one couldn't help notice the hurried buzzing of insects mere millimetres above the gravelled walkways.  Hundreds of them.  Flying pell-mell in every direction, and always atop the sunlit grains. The only reason I could photograph them was because I had my birding equipment.  My 500 mm lens's minimum focus distance isn't meant for insects, but it does in a pinch.  It also allows me to photograph from a distance; my macro equipment would be better, but I would never get close enough. The mining bees, so called because the females dig burrows up to a foot deep, like to nest in bare or patchy soil....

Western Thatching Ant - ever hear of an ant mound?

Image
Up to 40,000 western thatching ants make up a single colony, and they build quite the ant hill. Formica obscuripes, the western thatching ant, has a red head and black thorax and body.  While a red and black ant is nothing new, the fact that this species' head is the only red part makes it somewhat unique, certainly in this part of the world anyway.  If that wasn't enough, you can always look for what it calls home, a large, dome-shaped mound made of organic material.  I usually see them made of coniferous needles.  If you want to see a good example of one, click here .  Mounds may be up to a meter high, although the ones I have witnessed have been under a foot high. Ants, like most of their species, are foragers, heading out of their nests to collect food or building material.  The building material depends largely upon what is available in the area.  Soil, from the burrows, and plant debris are placed around the colony entrance.  A secondary nes...

Flash Meter - the tool you didn't know you needed.

Image
My Sekonic flash meter - A strong ally with the Force. I learned about photography back in the late 70s and early 80s.  My first flash was a Metz 402 - powered by a lead-acid shoulder-carried battery pack that had enough power to light up the other end of a hockey rink.  After that came a Vivitar and then a host of Nikon flashes.  Then I got into strobes - big ones, complete with soft boxes and barn doors. I quickly learned that using flash didn't always result in a proper exposure.  As camera sensors began to tie into flash TTL technology, the process became easier, but it wasn't consistent.  Did the flash have enough power to do the job?  You could play with flash output through flash exposure compensation, if your camera and/or flash had the feature.  That always took playing around, and you didn't always know if the exposure was quite right until you got it back to look at the results.   The problem increased significantly when not using ...

External flash - a powerful ally in the dark

Image
How to make your family brighter - use an external flash. Sunny days present a problem when trying to fill dark spaces with flash.  Brightly lit backgrounds with large EV values will demand either small apertures or high shutter speeds, or some combination of both.  If you expose for the shaded areas, you will blow out the background.  Built-in flashes can mitigate shadows a little bit, but unless you are very close to your subject, they just don't have enough power.  The best solution is a powerful external flash. Following the sunny-16 rule, the above photo (shot with slide, I don't have the exif) an ISO of 100 at 1/100th of a second would require an aperture of f/16.  Built-in flashes are only good up to about 2.5 feet at these settings; by 5 feet, the flash is two stops underpowered.  I was probably 10 feet away at the time; the built-in unit would have made no difference (other than catchlights in the eyes).  Even if the shutter speed was increase...

Bush Tit Nest - Just hanging around.

Image
Bush tit nests are unusual.  I photographed this on the Okanagan rail trail near Winfield, BC.   Saturday found a friend and I walking along the Okanagan rail trail near Winfield, BC.  There were several grey-coloured bag-shaped things hanging from several trees beside the path.  I looked at them, wondering what they were.  Possibly debris of some sort that had been blown up into the crown, or maybe some article of clothing that had become discoloured over the years.  Then, it occurred to me.  These had to be the nests of bush tits. The bag or sock nest of bush tits are made from grasses, mosses, and other vegetable matter woven together eith spider webs making them somewhat elastic.  The bowlshaped end is well insulated and is lined with feathers and fur.  The enterance is at the top.  The ones I saw were high up in trees; it would be unlikely for a snake to make its way up there.  The birds take up to a month to make the nest...
