9. Light conditions (position of
bird in relation to shade and to direction and amount of light): Originally clear, with sun slightly in front of observers
while at East Jetty viewing tower. At the Ferry, the bird was seen under
better lighting conditions, and photographed. |

power, condition): Leica APO Televid
82 telescope with 25-50 zoom lens, Zeiss 10x40 binoculars |

11. Distance to bird(s): At East Jetty, perhaps about ½ mile. From ferry,
300-500 yards or so. |

|
|
|
13. Habitat: Dredge spoil on west side of Calcasieu
River, then mouth of river itself. |
|
|
|
14. Behavior of bird /
circumstances of observation (flying, feeding, resting; include and stress
habits used in identification; relate events surrounding observation): First observed resting amid a large group of roosting
gulls, terns, pelicans, etc. After several minutes, the Glaucous
flew over the jetty and upstream along the river as gulls congregated around
a returning fishing boat. We then drove to the ferry, and refound
the bird as it rested on and flew over the river downstream from us. |
|
|
|
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): Nearly entirely white, with a pale bill
with dark tip. Other details not seen well at such distance. See photos. |
|
|
|
16. Voice:
None. |
|
|
|
17. Similar species (include how
they were eliminated by your observation): Larger
than the other gulls present (including Herring), and considerably paler.
Most likely confusion species was a bleached Herring Gull, but given the bill
pattern and lack of any dark markings on the wingtips, Glaucous
seems the best fit. |

obtained? (by whom? attached?): Yes, photos by Richard Gibbons attached. |
|
|
|
19. Previous experience with this
species: Fairly extensive, both in-state and in
