Thanks to James Merwin,Mark Veaters observation might be this species James researched.
Regardig exotic bird in lower picture contained in 13 September blog posting from Mark Veater: I didn't see the bird in the park; haven't seen it in the wild or in captivity; and I'm not making an ID. Nonetheless, the best match that I found on the internet when I googled "cacique birds" is a picture of what I believe is a Yellow Winged Cacique, although the bill is proportionately different than in Mark's photo. I've attached a link the picture below; but in way of a caveat, other pictures of Yellow Winged Caciques, as well as Yellow Rumped Caciques, show different proportions to head, body, and bill. Please let Mark know what I found as I hope that the picture may be of value to him. Feel free to post on your blog if you feel that it is of general interest. Jim
