Two different birds from Uganda (1 Viewer)

Hi there, I am totally new on this site and in this forum, but I have been an amateur birder for some years now.
Last year, I went to Uganda, and there are two species which have caused me some trouble to identify, so I really hope someone in here can help.
First picture is taken on Lake Albert in Uganda on March 8 2018.
My guess is a whiskered tern, juvenile (Chlidonias hybrida) probably, but I am really unsure.
Second picture is taken in Queen Elizabeth National Park on March 5 2018. So far I have identified them small gulls (larus minutus), but again, I am really unsure.
Both identifications are based on what I could find in different bird guides and on Google.

One of the Marsh Terns. (Whiskered, Black or White-winged Black).

White-winged is abundant ; Black is very rare there and would show a black spot on the breast. Whiskered breeds locally, but never gather is such big groups.

Great, thank you both!
The group of birds in the second photo are as you suggest white winged black terns, but the bird in the first picture is a whiskered tern - just found this page: https://singaporebirdgroup.wordpress.com/2015/10/09/white-winged-or-whiskered-terns/

Yes, I didn't say they were all White-winged, did I ?
