This is like one of those TV quiz show questions where you might be given multiple choice answers to select from. Except, with gutters, all of the answers could be correct!
The possible ‘cloggers’ could include leaf accumulation from trees shedding in the late autumn and early winter. Equally, there might be an accumulation of pine needles over time.
Rodents, dead birds, and other small animals could be decomposing there. These might have been dropped by larger birds (or even the occasional cat venturing onto a roof).
Then, there is a wide range of other materials which could find their way, either from on-going roof damage or by simply having been transported by winter winds.
