In reply to Dave Garnett:
Had a friend sending lots of photos like these late last year.
My guess for No 1 is one of the Hummingbird species. Wild guess Velvet-purple Coronet?
No 2 is a Blue-footed Booby, and No 3 I think is a Swallow-tailed Gull as both have obvious ID features.
Of course it is dependence on where you were and if those species exist there!
