Climate change is breeding ghastly conflicts in the wilds. According to a study published in journal “Current Biology,” a shift in migration and nesting timelines of two birds – the great tits and the pied flycatcher – is proving fatal for one.

The pied flycatchers that fly all the way from sub-Saharan Africa to northern Europe every year to breed now find their nesting sites pre-occupied by aggressive great tits, as their breeding cycles overlap due to climate-change related factors, notes Popular Science.

Normally, the warming temperatures are causing the trees in the region to leaf early, making the conditions ripe for a caterpillar boom, which is the reason why pied flycatchers are migrating sooner. On the other hand, milder winters are letting great tits linger on for longer duration. With these shifts, the two winding up in the same place, competing for same resources.

As a result, the environmentalists are observing far more fatal encounters between these two birds, with pied flycatchers paying the price with their lives, reports Eco Watch.
