Einstein doesn't like the rug in front of the kitchen sink to be picked up. I forgot one day and got this on camera. This is not an aggressive growl, (although it does sound like it!) generally it is a sound they make when nervous. It's the only way they have of showing us they are scared. Pretty impressive to say the least! <br />(This is the Einstein famous for his impression of Matthew McConaughey and not the "Einstein" that was featured on the TV show Animal Planet Pet Stars. The only things they have in common is the name, good looks,and the desire to entertain humans!) <br />Visit Einstein the Talking Texan Parrot <br />Website: http://www.einsteinparrot.com <br />Blog: http://einsteinparrot.blogspot.com <br />Facebook: http://www.facebook.com/einsteintexanparrot <br />Google+ https://plus.google.com/+einsteinparrot <br />Twitter: http://twitter.com/Einsteinparrot <br />Periscope: https://periscope.tv/Einsteinparrot <br />Pinterest: http://pinterest.com/EinsteinParrot <br />YouTube: http://www.youtube.com/einsteinparrot <br />Instagram: http://instagram.com/einsteinparrot <br />Vine: https://vine.co/Einsteinparrot <br />Snapchat: https://www.snapchat.com/add/einsteinparrot <br />Spreadshirt: http://shop.spreadshirt.com/einsteinparrot <br />Dailymotion: http://www.dailymotion.com/einsteinparrot
