A miscellany here, mostly cowbirds (great to give the photos sensible nos, esp when there's loads like here: 1,2,3... is tried and tested):

360: variable oriole
431: looks like screaming cowbird
435: perhaps screaming despite apparent blue gloss (=shiny)
451,457,977,979,068: ,,
053: shiny
132: pass but I don't think unicoloured
138: difficult but suspect the oriole again because: from the little I can make out the primaries are reasonably long, the apparent bicoloured bill probably isn't an artifact and I don't think the blackbird ever has a reddish eye

431 + 435 are the same bird, so are 132 + 138 and 8977 + 8979.

360: definitely variable oriole: see brick-red shoulder patch. Note slightly reddish eye, blacker tip and edges on bill.

Pass on the cowbirds, but to my untrained eye 431/435, 451 + 457 (possibly same bird?) all look similar in glossiness and beak/forehead shape and eye color;
in contrast with 8977/8979 and 9053 which look like they form a different group to me. Take this with a lump of salt, I might be giving too much weight to glossiness which is dependent on lighting.
(068: I don't know...)
132/138 look good for variable oriole to me for the reasons stated by The Fern; compare 360.

I think the glossiness we see is misleading. The q in that area is it shiny or screaming cowbird? ... Bill morphology is the most important character but supposedly gloss/colour can be used too. Especially where photos are concerned, I'd stuck to the bill.
