Additions to the List of the Birds of Louisiana
Lowery, George H., Jr.
Birds -- Louisiana
Our series of 107 Savannah Sparrows, collected in Louisiana almost
entirely since the publication of Oberholser's book, includes
representatives of five geographical races, as follows: 37 _savanna_, 24
_oblitus_, 12 _mediogriseus_, 8 _labradorius_, and 7 _nevadensis_. The
remaining 19 specimens show various combinations of characters and
appear to be intergrades, and so have not been assigned definitely to
any one race. I am indebted to James L. Peters for the identification of
most of our specimens. Since _mediogriseus_ and _labradorius_ have not
been reported previously from Louisiana, and since there is only one
Louisiana record of _nevadensis_ (Miles, Auk, 60, 1943: 606-607), actual
dates and localities of occurrence for these races are listed here. _P.
s. mediogriseus_ (specimens by Burdick, Howell, Lowery, Ray, Tucker,
and Wallace)--University, January 31, 1939; February 11 and 29, April
29, November 28, and December 16, 1940; December 6 and 7, 1941; October
10 and 25, 1942; April 14, 1943. Erwinville, March 11, 1941. _P. s.
labradorius_ (specimens by Burleigh, Lowery, McIlhenny, Ray and
Wallace)--University, February 15 and November 8, 1940; January 1, 1941;
December 11, 1943. 2 mi. NE Baton Rouge, January 1, 1941. Burtville,
December 8, 1939. Avery Island, May 3, 1939. Lake Charles, November 20,
1940. _P. s. nevadensis_ (specimens by Burdick, Lowery, and
Wallace)--Iowa Station, January 23 and 24, 1940. University, February 10
and March 10, 1940. University, December 7, 1941, and November 15, 1942.
Cameron, December 6, 1942. There are at present no _bona fide_ records
of _P. s. anthinus_ in Louisiana, since the one recorded example of that
race (Oberholser, _op. cit._, 647) appears, on reëxamination, to be
referable to _savanna_ (_fide_ J. L. Peters).
#Ammodramus savannarum pratensis# Vieillot, Eastern Grasshopper Sparrow
Eight specimens of the Grasshopper Sparrow taken recently in Louisiana
are without exception referable to _pratensis_. Our one remaining
specimen, a male collected at Pride on December 19, 1937, is an example
of _perpallidus_ as recorded by Oberholser (_op. cit._, 648). Although
the present series is inadequate for determining the prevailing form in
the state in the winter, it would appear that _pratensis_ is more
common, rather than _perpallidus_ as indicated by Oberholser.
#Chondestes grammacus strigatus# Swainson, Western Lark Sparrow
Oberholser cited only one Louisiana record for this race. The following
additional records are now available: a specimen was taken by Howell at
Cameron on October 31, 1942, and one was obtained by me at University on
April 13, 1945. The species is a transient in both localities. A
supplementary winter record for the Lark Sparrow in Louisiana is that of
an individual seen at Port Hudson on December 23, 1945, by Howell and
Newman. The bird was shot, but unfortunately, it was not retrieved.
