Like most things in science, there are published experiments on both sides of the DDT vs. bird issue. From my own observations living in one of the heavily studied areas in regards to DDT in the environment, I've seen tremendous increase in Osprey (the heaviest hit) populations and several other raptors since DDT was banned. There have been no environmental changes that would support such increases that could be used to support other theories. In fact quite the opposite, reduced open spaces, shore line hardening, reduced fish populations, increased devolpment...
