Tyche is a little slate lovebird. I've known him since birth, over a decade ago. He's always been small, since birth. He's very intelligent; he used to lift his sliding cage door, then hold it open with his legs to let his cage mate in or out.
Almost a year ago, he suffered some trauma while we were gone, and we took him to the vet (I noted the event in this post).
Since then he hasn't been able to fly anything like he used to. He'll still climb up to high spots and sometimes launched himself off, but he wouldn't be able to get any lift. However today I saw him fly across the room, a good 20 feet; the best I've seen him fly in a year!
He sleeps on a shelf above a window, which he hasn't been able to fly up to since whatever happened to him about a year ago. I put ladders so he can climb up to a table under the shelf, then another long ladder to the shelf. Sometimes he uses the ladders, but other times he prefers to climb up the curtain. When he gets to the top he moves along the top of the curtain to the ladder and hops between the rungs so he can get on its other side, to climb the last little distance up to the shelf.
As I wrote this, Betty, Tyche's mate, came and sat on my shoulder. I told her I was writing about Tyche. The birds know that I spend a lot of time on the computer and they are often curious about it, looking at the screen, walking across the keyboard, pecking at the keys...
