[Tweeters] Correction: Red-footed Booby Behavior Among Heermann's Gulls

[Dan Reiff via Tweeters]

No, I have not named the bird "Bobby, the booby".

Corrections:
Hello Tweeters Community,
I was able to "film" (video capture) the Booby's behavior for a few hours
last week. Neat bird!
As often happens, I was later able to see details of behavior on my 27 inch
IMac screen that I did not notice in the field.
I now have about 200TB of birds and their behaviors, mostly in 4K, 10 Bit,
422. For me, Filming is Very challenging to do and fun-
and sometimes frustrating, disappointing or wondrous and it has helped me
learn a lot about birds, including their species
specific and individual behaviors. I enjoy filming all bird species I find
and have a special interest in Owl and Nightjar species and their behaviors.
The bird slowly walked from the usual roosting spot on the building ridge
directly down to the mid roof. It stopped among the Heermann's gulls, which
tend to squabble with conspecifics. It then began what appeared to be
Forward Head Waving.

).
It first swung its bill back and forth about an inch each way, paused and
then two inches, paused, then tail wags, then 3-4 inches, followed by
substantial tail wags, then 4-5 five inches to the left then right. The
gulls continued to interact with each other, but did not engage the booby.
The 4K files sizes are very large and I do not currently have a way of
sharing them online.
