I wasn't able to get any pictures, but in my peregrinations around Bogota (mostly heading out to lunch!), I saw about 3 different birds.
The first was a brown-gray bird about the size of a cardinal or waxwing. It looked like it may have had a black crest that was lowered. It had a quite complex song with a couple of different phrases. I am unable to find an example after a quick foray online, so I'm not sure what it might have been.
I also saw some doves. From the "Birds of Columbia" site, I found some pictures which suggest it might have been a ruddy ground dove.
The last bird was a large-ish black bird with a yellow beak and legs. It looked like some type of Myna. However, I looked up mynas and they are defined as an "Asian bird". Another possibility from "Birds of Columbia" is the Great Thrush. But I'm not 100% sure on this one.
It was really disappointing that I was unable to get any pictures.
