Are they the full images reduced to 1024x683 or are they crops?
I did crop the images a bit to correct for framing, but I also reduced them to 1024x??? so I could post them.
The first couple are nicely composed, with the bird about 1/3rd in from the left. The last two are not, with the bird straddling the picture - it would have been better to have the bird on the left with some open space on the right. They are also rather noisy - the EXIF says that you were at iso1600 which is rather high for a Rebel. With relatively static subjects and short focal lengths of 200-280mm you would have done better to use slower shutter speeds and have some room for sharpening with a lower iso and less noise.
Sorry for the delta time for the reply - had a business trip to take.
Regarding the cardinal taking a bath - it was a very overcast day and my goal was to almost stop motion, but not quite. I wanted the viewer to see her motion while she was taking her bath. I had to increase the ISO to 1600 in order to get the shutter speed quick enough for what I was intending to do. I usually limit myself to ISO 800 or under on my rebel, but in this case, I had to increase it.
After cropping the image to focus on the bird, I couldn't get the noise levels where I wanted them without making the picture look like a painting. I included the original picture here so you could see what I was starting with. I understand what you are saying regarding the framing, but in this case, I didn't feel that there was something interesting enough to include in the framing to put the bird off to the side. Perhaps I cropped too much. The Titmouse picture was much easier to frame than this one.
I also included another one I took of another female cardinal. The only drawback here is the yaupon that's in front of her, but I thought this one was decent. In this case, I have the same framing issue as the previous one, not much interesting to put in the picture to move the bird to the side. In this case, I put the eye in the upper corner of the "third."
Thanks for the feedback!
