I agree with all the arguments also and I'm watching it all with my 300mm lens made by a robot ?
Undoubtedly a series of robotic tools, probably quite a few, depending on which parts are being made or assembled. Doing the glass is very different from doing the diaphragm. One human might do both by hand, but not one robotic tool. My mind boggles at how far manufacturing has come over the past 150 years, from "craftsmanship" to automated high-precision mass production. Image what a camera or lens would cost if all the metal components were individually fabricated by a human operating a lathe, milling machine, drill press, etc.?

I'll post any information I can get, We have many other bird species here in the same area and I have not seen any signs only the Cardinals and on at least 5 different birds in the last week alone. They seem to have healthy appetites and active as usual but I can only imagine far worse if it continues. I will as I said contact fish & game and or the college when as soon as as find a few more pictures of the birds from this week. I would think maybe the Dove would be affected also because both are ground feeders for the most part.. Many members of this forum shoot birds so I am anxious to hear from anyone else who has seen this.
I see you're a member to the Birding Group here. This thread fills up quick with pictures, and your questions may get overlooked. Have you considered posting a new thread in the Birding Group for better exposure?

Also, I believe the "female" cardinal with the black beak is a juvenile cardinal.

I'm sure your correct about her being a juvenile and there are many of them here I just haven't seen one with the black beak. Also I will post a new thread to the birding group., Thanks again !

I'm sorta feeling the same. What TC do you use? I have the Tamron 1.4X Pz-AF MC4 teleconverter. I only use it on my F*300. However I prefer to not use it when I can. Sort of defeats the purpose of the TC

I mean, it works and everything and it's most definitely as sharp but you lose one stop of light and at 420mm it's a bit harder to keep steady. I dunno.......
I'm using the K T6-2X.

It's an old 2x TC that is pretty good optically for what it is, but I'm sure your Tamron 1.4x degrades the image quality much less. In decent light I have no problems shooting ISO 3200, just have to adjust my processing accordingly. But as you noted, when shooting long (and sans tripod) tele it is difficult to hold the lens steady enough for precise composition.

A couple years ago I used the TC with a Tak 200/4 for a pic that printed nicely at 16" (I think) and has been on display at a local historical museum. It's not a remarkable photo in any respect, but shot at the right location for inclusion. So, in this case the TC did the job.

As I have been making photographs of the local wildlife at the same location I have began to notice recently the Cardinals have some kind of disease or sickness that is causing their head & chest feathers to fall out along with blotchy patches on other areas of their bodies. Also I have now seen two females with black beaks like the on in the photo I have posted. They normally always have orange beaks. Does anyone out there know what may be causing this or seen anything like it ? I'll be getting in contact with fish game as this is alarming for the amount of affected birds here in this relatively small area.
I'm thinking (hoping) this is a normal molting phase for these birds, and not some sort of fungal disease. Juvenile birds sometimes start off with a dark beak that lightens and changes to the appropriate color over time.

The baldness in Cardinals is the result of parasites. Feather Mites and/or Feather Lice.

Environmental and dietary factors can play a role as well.

More pics from my car. K-5/FA*600mm F4 ED [IF] on a Kirk window mount. What an awesome lens by the way








And these 2 shots the bird wandered up to the car and ended up too close to focus

Usually for flowers I pull out my macro lens as flowers don't fly (or swim) away when you get close to them. Birds and Butterflies, on the other hand... (from 2 recent visits to a local waterfront park, DA* 300mm, 1.4x Pentax TC)

Black Swallowtail



Common Tern



Ring-billed Gulls

Looking at the past couple of pages, interesting interactions.

One is the matter of the cardinals. Our hobby helps us to see things that we may not otherwise see. Good value.

Robots. I think this excursion into topics beyond the thread is the kind of thing that could lead to arguments. I do not mean it has yet crossed any boundary of the appropriate.
