I find a lot of difficulties in having sharp in focus images of birds in flight when there are trees and bushes in the background; no problems against the sky;does it happens the same to you?

It partially depends on how big the bird is in the frame. What are the AF settings you use?
Hi Paolo Settings will make a big difference
Are you using center point only or all of them? For flight I'm using the center point most of the time As Axel mentioned the size of the bird will make all the difference and also the contrast ... af will grab better !!
AF does not work well in every situation all the time. In some situations, AF does not work well. From D300 user's manual page 70, AF does not work well where/when:Originally Posted by Paolo Piazza
- There is no contrast between the subject and the background.
- The focus point contains objects at different distances from the camera.
- The subject is dominated by regular geometric patterns.
- The focusing point contains area of sharply contrasting brightness.
- Background objects appear larger than the subject.
- The subject contains many fine details.
I think those conditions could also affect the AF of the Canon cameras??
I find that it is a matter of practice and more practice (I am still TRYING to get it right and it is coming along nicely).
I tend to move the focus point into the BIF from the rear of the bird then practice keeping the centre point on or just ahead of the bird and I will often take hundreds od photos just to practice my panning skills.
Read Arties stuff it is invaluable but understand that BIF generally has the lowest keeper rate of all the photography disciplines (IMHO)
