13. Habitat: |
Deep
blue waters of the Gulf of Mexico |
14. Behavior of bird / circumstances of observation
(flying, feeding, resting; include and stress habits used in identification;
relate events surrounding observation): |
We
saw a group of Magnificent Frigatebirds chasing a
smaller bird and went to look. The
smaller bird was the Audubon's Shearwater.
The frigatebirds were faster, but the
shearwater could dive and evade that way.
Finally the shearwater flew away as the frigatebirds
seemed to lose interest. |
15. Description (include only what was actually seen, not
what "should" have been seen; include if possible: total
length/relative size compared to other familiar species, body bulk, shape,
proportions, bill, eye, leg, and plumage
characteristics. Stress features that separate it from similar species): |
See the pictures. |
16. Voice: |
Not
heard |
17. Similar species (include how they were eliminated by
your observation): |
The
tail looks relatively long and is dark underneath, eliminating Manx
Shearwater. The underwing
pattern suggests Audubon's over Manx as well.
The lack of white around the eye shows this isn't a Little Shearwater. |
18. Photographs or tape recordings obtained? (by whom? attached?): |
Many
of those present took pictures; I did too.
Mine are attached. |
19. Previous experience with this species: |
I've
seen several off Louisiana and some off North Carolina |
20. Identification aids: (list books, illustrations, other
birders, etc. used in identification): |
|
a. at time of observation: |
Other
birders called out the ID at the time |
b. after observation: |
I
looked at the National Geographic guide to get the scientific name and to
look at Manx and
Little Shearwater pictures. |
21. This description is written from: _____ notes made during the observation (_____notes attached?);_____notes made after the observation (date:_____); _____memory. I noted the time but otherwise this is from memory and the photographs. |
22. Are you positive of your identification if not,
explain: |
Yes. |
