Additions to the List of the Birds of Louisiana
Lowery, George H., Jr.
Birds -- Louisiana
A rather large series of Winter Wrens, all taken later than the date of
publication of Oberholser's book, includes three specimens of this race
and provides an addition to the state list. Two of the specimens are
males collected at Baton Rouge on November 23 and December 21, 1943
(Burleigh), and the other is a male shot at the same place on January
23, 1944 (Burdick). Several additional specimens in the series are
noticeably darker than the average _hiemalis_ and may have migrated from
a zone of intergradation.
#Turdus migratorius nigrideus# Aldrich and Nutt, Newfoundland Robin
The only two records for the occurrence of this race in Louisiana are
those of specimens taken at Baton Rouge on February 1, 1937, and
February 9, 1946 (Lowery).
#Hylocichla ustulata swainsoni# (Tschudi), Eastern Olive-backed Thrush
#Hylocichla ustulata almae# Oberholser, Alma Olive-backed Thrush
Only four Louisiana specimens of the Olive-backed Thrush were available
to Oberholser in 1938. He identified two as _swainsoni_ and two as
_almae_. We have since collected twenty-five specimens in the state,
seven of which are definitely _almae_. Of the remaining, all are clearly
_swainsoni_ with the exception of a few that appear intermediate in
color. The specimens of _almae_ were collected at Cameron, Baton Rouge,
and Baines on dates ranging from April 26 to May 16 and from September
29 to October 6. The specimens of _swainsoni_ were taken at New Orleans,
Port Hudson, Baton Rouge, and Baines between April 20 and May 16 and
between September 12 and October 28.
#Hylocichla fuscescens salicicola# Ridgway, Willow Thrush
Oberholser (_op. cit._, 474) recorded this race as a rare spring
transient on the basis of two records. However, eleven out of
twenty-three recently taken specimens are referable to _salicicola_,
indicating that _salicicola_ and _fuscescens_ possibly occur in
approximately equal numbers, in both spring and fall. The dates on which
_salicicola_ have been collected range from April 22 to May 16, and from
September 14 to 27. They were taken at Cameron, Port Hudson, Baton
Rouge, University, and Baines.
#Anthus spinoletta pacificus# Todd, Western Pipit
The only Louisiana record for this far western race is that of a female
taken by me at Jennings, on January 3, 1943. The specimen was sent to
Alden H. Miller, who compared it with material in the Museum of
Vertebrate Zoölogy and verified the identification. As a rule, I
scrutinize closely with binoculars all flocks of pipits, and as a
result, on several occasions have detected pale individuals that stood
out from the remainder of the flock. However, the above-mentioned
specimen is the only individual so detected that I succeeded in
shooting.
#Vireo solitarius alticola# Brewster, Mountain Vireo
