Well, I'm sure he thinks they're interesting and nice to look at and everything, but whenever he's playing in his room (where they live) and they open their mouths to "sing," their squawk is immediately followed by firm, insistent, three-year-old shushing.
"Be quiet, birds! Bad birds! Shhhhhhh!!!!!!!!!"
"Mom, I told those birds they are bad. They are TOO LOUD."
The weird thing about it is that when he shushes them, they actually shush.
