Hi all!

I have no clue how to separate Royal and Elegant Terns so I was hoping y'all could help me out All of these photos were taken in March 2020. Photo 1 was taken off the coast of Callao, the rest are from the Ballestas Islands off of Pisco.

(Photos 6-8 in next post)

#1 ?
#2 apparently Royal
#3-6 + 8: Elegant
#7 ?

Note extent of black on head and bill length

Agree. Suggest 7 probably elegant based on bill (quite fine, long).

Agree with the other IDs suggested. I don't think you'll be able to ID #1 or 7. While THE_FERN's reasoning on 7 is fair, it could just as well be Sandwich Tern with all the detail we can see

Cheers

Yes I considered that. But looking closer suggests the tail is longer than it first appears, and bill better for elegant imho. Anyways, agree we can't be sure...
