Was going to say C&C but the technical quality was not good enough on a couple.
Should have noted that Tamron service was very good and AF seems significantly better.
Should note that C&C is more than welcome of course !

Whats going on in the reflections with the ducks? looks like some strange patterns

Question for the OP: are you using a filter (even an ordinary UV filter) on the lens? If so, give it a try without the filter.
I don't know whether you cropped or shrunk the shots posted. If you shrunk them, they don't look quite as sharp as I'm told that lens is.
I have a Sigma 50-500 that was showing really bad IQ (worse than that even if it was shrunk) that took the form of blurriness that looked a bit like a double image and strange patterns in the bokeh in some situations. The out of focus areas showed strong diagonal lines in things such as grass where the blades of grass were oriented in a particular direction. I spent the better part of a year with poor photos and $200 trying to get Sigma to fix it. Eventually out of desperation I removed the filter just to see what happened...and the problems completely cleared up! I won't say the results were tack sharp (at least away from the center), but the weird bokeh and double imaging went away. See http://www.dpreview.com/forums/thread/2804505?page=2#forum-post-56636033
Here's a specific filter/no filter example from someone else. Mine was very similar: http://www.dpreview.com/forums/post/35342167
It's a different lens so it might not have this issue, but the patterns in the out of focus waves look a lot like this. It may be worth trying without a filter to see if you get better results.

Hello,
Thanks for posting. I have this combo too and I love it. Since you asked for C&C, here it is. You're shooting way too slow for the woodpeckers @ 1/500 sec HH. They aren't sharp. And the ducks @ 1/1000 is too slow as well - they are out of focus and there is hand held blur as well - nothing is sharp. f/7.1 can be sharp, but I've been using f/8.0 and I've gotten better results.
Also, if you have ANY kind of filter on your lens, take it off. Something seems to be going on here. If you're worried about protecting your lens, use a hood.
Here are a few shots I've taken the last few days...
Regards,
Kevin

It's always good to see someone else using the Tamron 150-600mm lens.
For C&C, it appears that in the first image that the bird is a little outside of the depth of field. It's tough to do sometimes when the DOF is so shallow. The second picture of the ducks should be sharper. I don't think it's motion blur but maybe it is something to do with the focus. The last one is good, but the branches can be distracting. Sometimes we have no choice, although.
Here's some of mine that I've recently taken all hand-held.
There was someone on the Third Party Lens Talk that found in his case that the telephoto lens was less-than-ideal with sharpness because of apparent QA/QC problems (he took it apart himself and fixed it, which is not generally recommended). I did have one problem with my lens and had it fixed under warranty about six months ago. Fortunately my lens takes reasonably sharp photos (that hasn't been a problem like the other one that was fixed).

Thank you all as always.
Austin_Luker, as Zee Char said, I believe it is just water ripples too.
Robert Krawitz - will try out removing the filter.
Kevin G - yes, will have to try at faster speeds. The light is not the best here so a constant struggle between ISO, shutter speed and aperture.
With the ducks, I really just liked the splash of colors and the (accidental) composition more than the technical aspects of the photo which are are dubious at tbest.
Digirame - I have seen your hand held shots previously and I am super impressed. Tack, tack sharp.
I have usually had the best results with the Tamron where it was supported on a railing, windowsill or tripod. Examples below
1. Lens on railing. Captive Owl was very close (maybe 20 feet)
2. Handheld
In some cases, I am okay with not so sharp photos, sometimes creatively like the one below from this morning (Rebel + Tamron 16-300) - had gone out for landscapes but saw these birds flying past this misty morning
3. Panned at slow shutter deliberately (700D + 16-300). As an example.

Nice one, thanks for sharing.

This set looks better than the first. Nice effect on image 3. Not sure where the AF point was on the first woodpecker. The ducks were a tad OOF.Thank you all as always.

On Woodpecker - I am guessing the focus point was on the lower part of the body as the bird was moving and would have been difficult to put the focus point on the head.
The DOF @600mm f6.3,and 40-60 ft is only 2' to 3' in front and in back so barely any scope for focus error. Pointing the lens straight up as for the woodpecker with a moving bird is a bit hard (as I am discovering) !

I agree about the filter or removal of it. The 150-600 is not the only lens that is made worse when a filter is attached the older Canon 100-400L was not too happy when having a filter on producing some horrible bokah which instantly disappeared when the filter was removed.
