Mine just stays the same old "boring" catbird. It does have some reasoning behind it, though.
1) The simplest reason is that they're my favorite bird. What they lack in appearance they more than make up for in personality.
2) I view a catbird as representative of a "conservative" similar to how I view a cowbird as representative of a "leftist". Catbirds can recognize their own eggs, so if a cowbird subsequently lays its eggs in a catbird nest (expecting the catbird to raise its young FOR it), the catbird will actually eject those foreign eggs from its nest. I view that as representative of "rejecting the socialism of leftists".
3) Catbirds are also rather good mimics. They can (quite well!) mimic the calls of other bird species. In fact, during breeding season, male catbirds will attempt to impress females with all sorts of mimicry vocalizations that they've learned over the years. The better a male is at this, the more a female will view the male as "experienced" and "resourceful" (IOW, as a good mate). As this relates to JPP and my avatar, I personally enjoy mimicking the vocalizations of leftists from time to time (poking fun at them).
4) A catbird's preferred habitat is within dense shrubs/thickets and they are generally reclusive. I find that behavior to be representative of my own behavior.
