jenb, that cracks me up about the sneezing imitation! Why is it that birds love to hear us sneeze?!?! LOL! Both of our birds imitate our sneezes, especially my husband's since his is VERY LOUD and he does 5-6 in a row at a time! They LOVE it when he sneezes! Then they both have to sneeze too! Today I sneezed and my Quaker also had to sneeze. Usually the ekkie won't bother with my puny sneezes. He likes the husband's! :-)
They also like my hubby's cough and will imitate that.
At night, they each have a low pitched "good night" and "goodbye" and a higher pitched one. The ekkie especially likes using the higher pitched one - too cute! :-)
