Another Tern Colombia (1 Viewer)

I have pretty much convinced myself that the first two images shows a first year Yellow-billed Tern. I think the second set of images may show the same or a similar bird even though the time in between was about 45 minutes. However, some doubt is still present -- I got the impression from the guide that Yellow-billed was not exactly common in the area.
For comparison of the first bird look for example at ML103210551 - Yellow-billed Tern - Macaulay Library
Thanks for any comments.

Think it's ok. Large amount of black in wings should rule out least. Ebird for there suggests yellow-billed is not rare
