Research from the University of Michigan indicates that insect populations at Long Point Bird Observatory have decreased by over 60% since the 1970s.
This significant decline in available food sources has resulted in smaller tree swallows emerging in recent years.
The implications of these changes are concerning, as the smaller size of the birds is associated with lower reproductive success.
