Blackbird in Las Vegas

I'm tired but wanted to write before I work tomorrow.  I had a fun time in Las Vegas this weekend with my good friend "S".  We walked and walked and walked, ate a little, saw some shows, and enjoyed ourselves.  I saw one bird there the entire weekend and I've got to say its sound was better than anything else I heard all four days and nights with maybe the exception of the Human Nature who put on quite a show despite the fact they are white guys from Australia.  All I'm going to say is what happens in Las Vegas stays there with another exception that was pointed out by "S" is the fat that now adorns our bodies - that always seems to come home with us.  http://www.youtube.com/watch?v=COrdhqp0wlQ&feature=colike
As I look for pictures and descriptions of this bird, I find that it looks a lot like the Great-tailed Grackle.  So, this is a bird I had never heard of before.  Below follows some info about this beautiful creature:
The Great-tailed Grackle (Quiscalus mexicanus) is a medium-sized, gregarious passerine bird native to North and South America. A member of the Icteridae family, it is of the ten extant species of grackle and is closely related to the Red-bellied Grackle and the Velvet-fronted Grackle. It is sometimes referred to as a "blackbird", though it is not a member of the New World blackbirds, nor is it related to any of the five species of Old World blackbirds (all of which are species of the Turdus genus). Similarly, it is often called "cuervo" in areas of Mexico, although it is not a member of the Corvus genus, nor even of the Corvidae family.
Males reach up to 43 cm (17 in), including a tail that is almost as long as the body, weigh 230 g, and are jet-black with a violet-blue iridescent sheen to the feathers. Females are significantly smaller at 33 cm (13 in), weigh 125 g, and are mainly brownish-black, with a pale brown throat and belly. This morphological difference between males and females of a species is known as sexual dimorphism.
The Great-tailed Grackle and Boat-tailed Grackle were once considered the same species. Some species of grackle, usually the Great-tailed, are confused with an American Crow when people unfamiliar with bird identification are asked to identify a dead blackbird. This usually occurs when birds need to be identified as candidates for West Nile virus.^{[citation needed]}

Distribution and habitat:  Its range stretches from Kansas in the northeast to southern California in the northwest down to northwest Peru and northwest Venezuela in the south; the grackle's range has been expanding north and west in recent years. It is common in Texas and Arizona in the southern regions. It is commonly found in agricultural regions and suburban environments, feeding on fruits, seeds, and invertebrates.

Behavior:  This bird has a large variety of raucous, cacophonous calls, and is widely considered to be a noisy pest species, though its range expansion has not been aided by human introduction (compared to the European Starling). The females can travel in flocks and they share food. When a male spots a female, he engages her by puffing up and gaping his mouth. He then proceeds to make loud calls and follow the female. The female will allow the large males to mate with her; she will usually reject smaller males.
