eurekalert.org – University of Groningen (UG) biologists have discovered that climate change has an effect on the regular clashes between great tits and pied flycatchers during the breeding season. In some years, great tits killed 10 percent of the male pied flycatchers. UG researchers have published an analysis of this behavior on Jan. 10 in the journal Current Biology.
