Yes, they can be fairly aggressive. Quite a few times a week, they'll chase the Grackles out of the yard. They come in 5-7 at a time, set up a perimeter and trade off ; one eats, others guard, switch. Pretty cool they way they work.
lol
Thank you for the thread links, I'll definitely post the bird stuff there instead, thank you.
The 400mm.... *sigh* it's a good lens. Maybe I just don't have it down yet - shutter +ISO combo - but I find I only get good, nice sharp images about 40%. It's pretty frustrating lol.
Example: A female cardinal will come. They usually survey the scene before actually hitting the feeders, so I know I've got a good minute for shots. I won't move, take 10-15 shots, drive mode hi speed, at least 320 shutter = maybe 5 good ones. Rest are just not sharp, I don't get haha.
The other day there were red polls in my yard at my feeders. I haven't had them there for 5 years, the last images I have of them were taken with my Sigma 70-300. I went out, even though the light was poor. I took 230 images and got no keepers. The light was dim and blue, I had very little dynamic range etc. For me the answer is simple. Go out on bright sunny day with lots of light, try and keep your shutter speed around 1/1000s or more, 1/2000 for birds in flight. Try and keep your ƒ-stop at least ƒ5.6 and ƒ8 if you can. 5% good ones is actually doing really well. When I'm out in my blind I often take 700 images to get 20 I like. When I have the birds in my viewfinder I often shoot 23 shot bursts that fill the buffer. Many are thrown out because I don't like the pose, and I frequently have motion blur at lower shutter speeds. When eating their little beaks move at an alarming rate often causing motion blur under 1/1000s. And usually my depth of field is narrow if they move their heads between shots they move their heads out of acceptable focus even when the body in still spot on.
Shooting smaller birds is fraught with challenges. Even when every thing else goes well, not every pose looks as good as every other pose. You simply cannot react in time to catch a specific pose. You have to shoot a burst and hope every thing falls in place. Anticipating movements is spotty, they are by nature unpredictable in their movements. A lot of what non-small bird photographers will tell you to do is nonsense, it's an art in and of itself. Its definitely tougher with a non AF lens. Shooting with the 1.7x AF adapter (partial AF) will cut my shots to 200 from 700, shooting with an MF lens would probably cut it to 60.
But bottom line, try and get your ƒ stop to 8 and your shutter speed to /1200 (a nice compromise) and keep your ISO between 100 and 400 and you should get some images. Totally agressive post processing is also necessary. I typically find one I like then delete everything before it and do the same, go to the next one I like, mass delete everything between those two. To select even 200 shots in short period of time, you need to be fast and efficient. If it's borderline, toss it, keep only your best. If you don't your "bird folder" will have way too many images in it in the blink of eye.
