Agree with JW except
1 - Buff-throated Saltator - the bird looks too warm on the upperparts rather olive..

Here are a couple more photoso of the Saltator. Throat seems to be yellow in most pics but you can also see white in some.
.... Is that green tinge digital? Affected by the surroundings?
I didnt even notice that these were taken at Heliconias!- great spot for several uncommon species but typically bad weather. Yes, as BirdBoyBowley says, should be Groove-billed for reasons mentioned. Does look like it might have grooves on bill too.
