California Bird Disaster is an event that first occurred in 1960s and finally in 1980s after pet owners released non-native birds of various species due to laws on some exotic pets being enacted and/or pet owners not wanting their pets anymore. Most birds that were released into California during those times were genetically engineered by their pet owners just before releasing them to allow them to thrive in colder and drier climates really well, having the ability to breed fast and often (genes for that used from rats and mice), herbivorous birds having wide variety of plant foods in their diet (also used genes from rats and mice), and the ability to tolerate colder climates and drier environment (used genes from various native birds).
