It kind of looks like a dead fir tree to me, great for perching in though! ;D

Peregrines aren't woodland birds like Merlins so they don't sit in trees because they like to sit in trees. They will sit in trees when they give them clear views of hunting grounds (like wetlands or farmers fields) - peregrines hunt in the open, either above cities or in clear areas like wetlands, along shorelines, over farmers' fields, that kind of thing. If you notice the tree doesn't have needles or leaves, its more perch than tree, nothing to get in the way when a peregrine's metre wide wingspan is open. Another option could be if there were few or no other perch sites near a nest or hack site, given a choice between sitting in a tree or sitting on the ground, peregrines would prefer some altitude.
And a hacksite is the same as a nestsite, the only difference is the way birds are released. From a nestsite, the chicks fledge when they are ready from a nestbox or whatever the adults have used for a nest. From a hacksite, captive-bred chicks are able to fledge (again when they are ready) after the hackbox is opened for them.
