Deadly Bird Battles May Be Another Weird Consequence of Climate Change - Gizmodo

Climate change seems to be leading to more fatal conflict between a pair of bird species, according to a new study. The research demonstrates an important indirect consequence of a warming globe.

  The scientists noticed that some years, they’d find more dead flycatchers in the tit’s nest boxes than in others.

  When the pied flycatchers arrive in Europe, they look for suitable cavities to nest in—like the nest boxes set up for great tits.

  The larger, more robust tits overpower the docile pied flycatchers while defending their nests, leading to dead flycatchers in great tit nest boxes.

  Anyway, the scientists studied how many dead pied flycatchers ended up in tit nest boxes for a decade, also recording when the pied flycatchers arrived and when both species began laying eggs.
