Need a bit of help here .

I own both these lenses, and given that using a 1.4x loses about 1 stop (is that right?) , am I better using this with the 70-200 2.8 instead of the 100-400 for shooting birds about 12ft away when the light is fairly dull?
Small finch-sized birds.

I am finding with the 7D that the iso has to be quite high using the 100-400 if I want about 1000 shutter speed. Aperture about 5.6 to blur background.

At 12 ft I would use the 70-200mm 2.8 with the 1.4x. I find that I like to use the 70-200mm with 1.4x up to about 15 ft, anymore than that and I just don't have enough reach, (for small birds).

Yes I think I should have done - I was using the 100-400 but the Iso was up to 3200 for the first shot, 800 for second.

Did you take them through a window? I would avoid doing that too if you could, it's like having a really thick crappy filter on your lens. :D

Well that and that 3200 ISO certainly didnt help either. Lots of grain.

I know - but they wouldn't have been there if I had gone outside.

I did try the 3200 iso through NN & it helped quite a bit.

I'm quite pleased with the other one at 800 iso - next time I will open the window - idleness really (& also there was a biting wind outside)

Go for the longest FL lens you can afford if your objective is shoot birds. I am using a Canon 400 5.6L and find it right for my purpose. The 70-200mm even with the TC is just too short especially for small birds. These bird shots taken with the Canon 4005.6L:

I thought I had got all the lenses I needed- :) the shots are great.

Seriously, shooting birds is something I wanted to try mainly because of my camera club - I don't shoot enough nature & never have enough images for the competitions (2 images for colour,mono & nature every month), and I was interested in the challenge of shooting something different.

I don't really specialize in any particular field (am a keen hobbyist) - but have great admiration for bird shooters - It takes a lot of skill and patience to shoot first class bird images. - I was surprised how high the shutter speed needs to be!

I shall try and improve with the lenses I have got presently (can't really justify any more purchases - the 7D cleared me out).

maybe next year............

Get a flash. That will help along with better beamer but for closeups like 12' away bare flash will be more than enough.

I agree with Geff when he says... Go for the longest FL lens you can afford if your objective is shoot birds.

I've used my 70-200 with a 1.4 for birds in my backyard at 12 feet and been disappointed with the IQ not to mention that I still had to crop at that distance and didn't like the results

ISO 3200 can be ok, the problem is that you've also cropped the images heavily as well.

If you're having problems with shutter speeds, so long as the bird isn't moving around too quickly you could try using a tripod or monopod. These (https://photography-on-the.net/forum/showthre​ad.php?t=867326) were at ISO 1600 and don't look noisy, not because I have any fantastic noise reduction going on but simply because I didn't have to crop the hell out of them.

I even prefer to add a TC and up the ISO to compensate than having to crop extensively.

I agree with most here, 400mm is really helpful shooting birds. You can get good shots below 1000 shutter speed with the IS on the 100-400. Here's a couple demos, neither one was in really bright light.
