Attack of the Brain-Eating Killer Songbirds

The video explores the unusual behavior of great tits, a type of songbird, which have developed a taste for bat brains as a survival strategy during harsh winters in Hungary. This behavior, observed since the mid-90s, is thought to be a learned adaptation passed down through generations. The phenomenon has also been reported in Sweden and Poland. Additionally, great tits have been seen eating the brains of pied flycatchers, possibly due to climate-induced breeding conflicts. The video discusses the potential reasons behind these behaviors, including nutritional benefits and survival needs.
