Phys.org / Crashing insect populations lead to smaller tree swallows that reproduce less

Since the 1970s, the number of insects at Canada's Long Point Bird Observatory has dropped by more than 60%, according to a new study led by the University of Michigan. Because of this, today's birds are smaller and facing ...
