Additions to the List of the Birds of Louisiana
Lowery, George H., Jr.
Birds -- Louisiana
Aside from Holt's statement, Oberholser had only five other records for
_falcinellus_ in Louisiana, one being a market specimen with incomplete
data and therefore of questionable scientific value. The remaining four
specimens were taken by E. R. Pike near the mouth of the Mississippi
River on November 13 and 17, 1930, and are now on deposit in the Chicago
Academy of Sciences. Recently I borrowed these specimens for
reëxamination with the following results. The three taken on November
17, 1930, are _mexicana_ and not _falcinellus_ as labeled and so
reported by Oberholser. The single specimen taken on November 13 is,
however, correctly identified as _falcinellus_. Alexander Wetmore kindly
examined the material for me and confirmed my identifications. The
occurrence of _falcinellus_ in Louisiana thus hinged on Holt's statement
and one preserved specimen. However, on July 23, 1944, in the marshes on
Grand Isle, Jefferson Parish, Louisiana, I encountered a flock of 12
immature ibises that impressed me by their blackness in contrast to the
color of glossy ibises with which I was familiar in Cameron Parish. Two
specimens were collected and both proved to be _falcinellus_.
Holt's published observations cannot be positively refuted, for we
cannot be sure that a colony of _falcinellus_ did not exist in Cameron
Parish in 1932, nor that the portion of the rookery under his
observation did not consist of a segregated population of that species.
However, ten years of field observations by other ornithologists have
failed to disclose the species which Holt considered a common nesting
bird in an area where we now know that only the White-faced Glossy Ibis
occurs. The fact that Holt specifically stated that he failed to find
the white-faced bird at any time in his stay in Cameron Parish is
difficult to explain, but this much is certain--the present known status
of _falcinellus_ in Louisiana is that of only a rare and casual visitor.
#Branta canadensis hutchinsii# (Richardson), Hutchins Goose
Oberholser (_op. cit._, 89) cited only one Louisiana record for this
goose. The bird in question was shot but apparently not preserved.
Consequently, the status of the race on the Louisiana list was subject
to question. Recently, however, two typical specimens of _hutchinsii_
were obtained in the state, one by Edouard Morgan, near Lake Catherine,
on November 7, 1942, and the other by Herman Deutsch, four miles above
the mouth of the Mermentau River, on November 2, 1944. The former is
displayed in the Louisiana Wildlife and Fisheries Exhibit in the
Louisiana State Museum, and the latter is now in the Louisiana State
University Museum of Zoölogy.
