the harmless/intelligent black crow...

 Crows exhibit strikingly intelligent behavior patterns. They maintained an intensive communication, and have even caught on using primitive forms of tools to solve problems, something that until recently was reserved to humans and great apes. In addition, crows (in fact all Corvids)are songbirds! That is something that probably only understood by bird taxonomen, taking into consideration their scratching.(copied from birdprotect the Netherlands)
