Study first
Do a little research into the behaviour of your chosen subject – for example, the type of habitat it is likely to be hunting over – and prepare accordingly by getting to the venue as quietly and inconspicuously as possible. If you can, visit the location beforehand: this will allow you to find the best spots for you to set up your camera.
Research timings
You are more likely to see your subject at certain times of year. Spring is generally a good time, as birds will be feeding young. Birds like barn owls hunt during the day as well as at night. Kestrels hunt during the day over meadowland, looking for small rodents. Red kites are more like scavengers, so feed on carrion. However, they will take small chicks like ducklings, so keep this in mind.
Pick up speed
Get to know your gear inside-out, so if you need to change a setting quickly, you don’t miss the action while looking through menus on the back of your camera. Most cameras have a function (Fn) button, which can be customised to perform certain actions quickly. It’s worth reading up on this and using these to your advantage with your most-used functions.
