Today's forecast talked about sunlight and I knew that would give me another good opportunity to try to photograph Nuthatches in flight.  My results are getting better and better and I now know what I need to do to achieve success. Bright light is an absolute necessity but positioning of the camera in relation to the birds flight path is quite relevant  as well.  It is very important to try and predict the trajectory which a bird is going to take when it flies down to feed.  If you do that then you have a better chance of the bird passing through the point of focus.  Next time we have a bright day I will have another chance to practice.  I have a plan to use para-cord attached to a tree and down to the feeding stump,  This will give me an exact line that a bird will fly on..  It will be just a case of focusing on the cord which will be the flight path of the bird.  Then I will set the focus anywhere along the cord. Then with the cord removed  I will know where the bird is predicted to be along the flight path.  I think this will work but only time will tell.  Whether all of this  is a bit of overkill, I will only know once I have tried it out but it certainly won't do any harm. But what is certain is that little woodland birds fly at really fast speeds and I am going to do some experiments to see exactly how fast that is. With a stop watch I will record the time it takes to fly a set distance and then just do a basic time, distance and speed calculation. At the moment it's just Nuthatches and Coal Tits that are using the feeder regularly.  Oddly, Siskins as yet haven't visited the feeder while I have been there which is odd because I have heard and seen them in the trees all around and over at the feeders by the HQ siskin are pretty much constant visitors and that is only just 300 yards away.
