I just heard the sweetest little tune from one of my bobs. It wasn't the 'bo bob white' call but more like a melodic little whistle tune. Kind of like 'doo doo dododo dododo dododo. doo doo dododo dododo dododooo'. Is that a common vocalization? Man they're starting to mature so quickly! I normally only hear peeps from them. Hubby & I were sitting here watching Wheel & both looked at each other when we heard the whistling. We've got a songbird in the house but she doesn't sing like that! LOL
