REPORT FORM
This
form is intended as a convenience in reporting observations of species on the
Louisiana Bird Records Committee (LBRC) Review List. The LBRC recommends the
use of this form or a similar format when submitting records for review (to
assure that all pertinent information is accounted for). Attach additional
pages as necessary. Please print or type. Attach xerox of field notes,
drawings, photographs, or tape recordings, if available. Include all photos for
more obscurely marked species. When completed, mail to Secretary, Louisiana
Bird Records Committee, c/o

|
|
|
6. Reporting observer and address:B.
Mac. Myers III |
|
|
|
7. Other observers accompanying reporter who also identified
the bird(s):Dave Patton, Hans Holbrook, Melvin Weber |
|
|
|
8. Other observers who independently identified the
bird(s): |
|
|
|
9. Light conditions (position of bird in relation to shade
and to direction and amount of light):variable, but often excellent |
|
|
|
10. Optical equipment (type, power, condition):10x42 Eagle |
|
|
|
11. Distance to bird(s):variable, but as close as 25-30
yards |
|
|
|
12. Duration of observation: maybe 15 minutes?? |
|
|
|
13. Habitat: open gulf, but we were chumming and there
were gulls around |
|
|
|
14. Behavior of bird / circumstances of observation
(flying, feeding, resting; include and stress habits used in identification;
relate events surrounding observation): chased gulls, flew around, seemed to
be hunting for gulls to chase |
|
|
|
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): When it first
approached, something about it suggested Parasitic to me, just its shape and
flight I guess, before I could really see anything specific about it. It
passed fairly close overhead and both Hans and I exclaimed “Parasitic”. That
pass clearly showed the fairly well developed,
sharply tapered, spearpoint central rectrices. It flew around some, and we
chased it, and obtained more excellent looks, and Dave and Hans got fine
potos. Clearly a jaeger, seemed somewhat light and
dashing for a Pom. Upperparts dark, with some light shaft markings of
primaries. Dark cap, less extensive than many poms. Gray breast band and some
barring along flanks. No barring of underwings, so I guess that makes it an
adult. Barring on undertail coverts. |

|
|
16. Voice:not heard |
|
|
|
17. Similar species (include how they were eliminated by
your observation):I think that the shape of the
central rectrices alone would eliminate both Long-tailed and Parasitic. Other
characters are more subjective, but they seem to me to support Parasitic. |
|
|
|

|
|
|

gulf; more in the Pacific and the arctic |

birders, etc. used in identification): |
