Really interesting study!

I'm curious as to whether the study is considering whether birds will use an otherwise undesirable tree (or a part of it) if there is some other factor (e.g. adjacent food) that also drives their behaviour. For example, I know from observing my own (UK) garden birds that many of them will perch in trees near to my feeders for an initial recce or to eat collected food, but that they don't otherwise use these trees for perching.
