If you're aware of any studies that address this issue, I'd appreciate information I can pass on to him. Thanks.

Someone who is writing a book about ants asked me about the question
of whether the prey resource base is likely to be more unpredictable
in the temperate zones, "with greater and more varied ups-and-downs
that might affect generalist insectivores, whether bird or ant." He
writes: "In addition to predictable seasonal variation in temperate
areas, there is probably variation caused by cold or warm snaps etc.,
that might fairly often leave temperate animals unexpectedly
hungry? Is there evidence for this?"
