I was down at the Colpoy’s Bay shoreline for the sunrise a couple of times in week 19. As the sun rises around 6 a.m. at this time of year I was down there before 5:30.
The first morning was mostly cloudy with a wind so the water was quite choppy.
The second morning had a mainly clear sky. Less windy so calmer water.
A sequence of photos taken on the Lake Huron shoreline in the spring.
I was photographing a Common Tern on a rock in the water when a second bird flew in.
The second bird landed and approached the one on the rock. By the front birds wing position it was fairly obvious what was going to happen next.
The birds mate. I’m guessing that they were a well established pair as the male didn’t bring a fish as a courtship offering.
After mating both birds started preening.
A bit of an odd one from me this week for a couple of reasons.
Firstly, I have been avoiding photographing birds on feeders for years, or more probably, decades. I got tired of editors picking a bird on a feeder over other shots of the same species in natural settings.
Secondly, this is unusual behavior, which is why I photographed it. A grab shot after I got home Friday afternoon. The bird has been back regularly over the weekend but I haven’t had chance for a second attempt at a better shot.
The photo shows a male Black-throated Blue Warbler coming to the Grape jelly in an Oriole feeder. It didn’t do it once, the bird has been coming to the feeder regularly for three days now.
I did some research and found records of them taking sugar water in Hummingbird feeders but no records of them pretending to be an Oriole and eating Grape jelly.
I submitted a report of the bird and its behavior, including the photo below to one of the Ontario bird sightings websites. The report is being ignored as far as I can tell.
This week’s Cosmic Photo Challenge is Natural Patterns.
First, some Cotoneaster berries. They sort of remind me of a fish skeleton.
Next, some Bracken fronds. Another reminder of a fish skeleton maybe.
And finally, hoarfrost rimmed Privet leaves.
The male Eurasian Blue Tit feeding the female during incubation. The female does leave the nestbox during the day but never for long.
In a few days the activity in the nestbox is going to increase dramatically.
In the early 1980s I was running the photo department at a scientific research establishment. This involved a wide variety photo techniques to record a range of subjects.
However, polarized light photomicroscopy wasn’t used for anything work related. Having seen the results of other people I decided to investigate the technique. In those days that meant researching in literature rather than simply Googling as you would these days.
Now I will admit that I am writing this from memory, I have googled the subject and what I have found matches my memories of the technique.
I applied drops of a Sodium Thiosulfate solution to some microscope slides and left the solution to evaporate so that crystals would form.
I mounted a polarizing filter between the light source of the microscope and the slide stage. Once the Sodium Thiosulfate had crystallized I put one of the microscope slides on the stage and put a second polarizing filter above the slide. When you rotated one of the polarizing filters the colour of the crystals changed.
The first photo shows what I found to be a fairly typical example of the crystals.
This photo shows small patches of colour against a mostly dark background. I’m guessing that this is a result of the orientation of the polarizing filters.
A Marbled Godwit on a section of Little Quill Lake shoreline. Taken one spring in the late 1990s in Saskatchewan.
I remember spending some time with the bird but had forgotten how many photos I had taken until going through my slide archives and digitizing some a few years ago.
The bird feeding.
After feeding the bird decided that it was bath time.
After bathing the Godwit had a long preen.
