ON SOME BIRDS FROM SANTA MARTA, COLOMBIA 
BY OUTRAM BANGS 
Mr. W. W. Brown, Jr., who is collecting in the Santa Marta 
region of Colombia for the Bangs Collection, sent a short time 
ago nearly seven hundred beautifully made bird skins as the re 
sult of his first two months' work from middle of Dec., 1897, 
to middle of Feb., 1898. These .birds were all taken within fif 
teen miles of Santa Marta and at elevations ranging from 500 to 
nearly 6000 feet, the larger part, however, being from the low 
lands. Mr. Brown has not yet visited any of the higher moun 
tains. I have thought it best to publish briefly on the collections 
as they come in, describing the forms which appear to be new 
and giving mere lists of the better known species. These prelim 
inary notices may be followed by a more elaborate paper when 
the whole region of the Santa Marta Mountains has been cov 
ered. 
I am much indebted to the unfailing kindness of Mr. Robert 
Ridgway and Dr. Chas. W. Richmond in helping me identify 
the birds and allowing me to work in the National Museum and 
make comparisons with the material in that collection. 
A series of the birds has been presented to the United States 
National Museum ; the rest of the collection, including the types 
of the new forms, remain in the Bangs collection. 
(NOTE. All measurements are in millimeters.) 
Crypturus columbianus Salvad. 
1 specimen. At the time the British Museum Catalogue appeared this 
bird was known by the type specimen alone. The one example so far 
sent agrees exactly with the description of the species.

Crypturus pileatus Bodd. 
1 specimen, 9 ad. This one specimen is very different from the gen 
eral run of C. pileatus, and probably represents a good race, at least. It 
is much deeper in color. The lower parts are a deep rich cinnamon with 
out grayer pectoral band.

12 and 13, 1898, a pair of this rare parrot, known before only from Vene 
zuela. These birds agree exactly in measurements, color of bill and gen 
eral coloration with the descriptions of P. sordidus. An actual comparison 
of specimens, however, might well show the Santa Marta examples to 
represent a different race.

Subspecific characters. Size of true G. ruficauda; bill longer; sexes very 
different, the female being much paler below than the male ; colors above 
about as in true G. ruficauda; below, in ^, throat white, slightly washed 
with pale orange rufous; belly and sides, back of green pectoral band, 
orange rufous ; in 9 > throat white, extensively washed with orange buff;

of bill, and color in this series, and the long bill, great sexual difference 
in color, and paler under parts in both sexes distinguish the birds of the 
Santa Marta region as a good subspecies of G. ruficauda.

Type from Santa Marta, Colombia, No. 5103, coll. of E. A. and O. Bangs. 
J ad. Collected Feb. 8, 1898, by W. W. Brown, Jr. 
Subspecific characters. Similar to M. wagleri of Panama, but much 
smaller; much more white on inner tail feathers, the inner webs being 
white to the quill, with three or four small black spots and black tips ; 
much larger than M. neglectus, with much longer bill. 
^feg. J*, wing, 107.6; tail, 51.6; exposed culmen, 24. 9, wing, 104; 
tail, 49.4; exposed culmen, 22.2. 
Remarks. M. wagleri of Panama seems to be specifically distinct from 
M. subelegans of Venezuela, the former having the crown patch contin 
uous red from crown to nape, while in the latter the crown patch is 
broken by brownish between crown and nape. Unfortunately there are 
no males of M. neglectus in the National Museum collection, but this bird 
is so much smaller than M. sanctse-martse and has such a very short bill as 
to be at once distinguished from it. M. sanctx-marlx is a small race of 
M. wagleri, with much more white on the inner pair of tail feathers, the 
black markings being usually spots, not bars.

Subspeciftc characters. As compared with specimens of true D. olivacea 
from Panama, bill much smaller ; wing a trifle longer ; tail longer ; colors 
above more olivaceous ; wings darker, more olive, less rufous. 
Size. (j\ wing, 106.4; tail, 87.2; exposed culmen, 24. 
Remarks. In birds from Nicaragua the bill is still larger than in true 
D. olivacea and the wing considerably shorter. They appear to represent 
another good subspecies.

Type from Santa Marta, Colombia, No. 5359, tf adult, coll. of E. A. 
and O. Bangs. Collected Feb. 2, 1898, by W. W. Brown, Jr. Altitude 
5000 ft. 
Specific characters. tf adult, size very small ; bill slender and small ; 
much white on two outer pairs of tail feathers; wings dusky, edged with 
greenish yellow ; tail dusky, outer feather with the inner web white for 
its terminal half, second feather with the inner web white for its terminal 
third ; nape and interscapulum dull olive green with dusky markings on 
shafts of feathers; crown patch shining chrome yellow; rump and upper 
tail-coverts wax yellow ; under parts, from chin to under tail coverts, dull 
gamboge yellow, slightly more olivaceous on flanks. 
Size. cT adult, wing, 66.4; tail, 44; exposed culmen, 7.8. 
Remarks. Mr. Brown took at an altitude of 5000 ft. the type of this 
species, and at 3000 ft., Feb. 19, 1898, a young female in nestling plumage. 
This new Sycalis, which I have named for Mr. Brown, is not closely re 
lated to any known species, its very small delicate bill, small size, the 
great amount of white in its tail feathers, and its peculiar coloring dis 
tinguishing it from all others. 
Cyanocompsa concreta sanctae-martae subsp. nov. 
5 specimens, c? d\ 9 
Type from Santa Marta, Colombia, No. 5361, J 1 adult, coll. of E. A. 
and O. Bangs. Collected Feb. 2, 1898, by W. W. Brown, Jr. Altitude 
3000 feet. 
Siibspecific characters. Similar to C. concreta cyanescens, but adult male 
still more decidedly blue, the general color dull grayish blue (interme-

140 Bangs On Some Birds from Santa Maria, Colombia. 
diate between indigo blue and dull china blue). Adult female similar to 
that of C. concreta cyanescens, but duller brown (upper parts nearer bistre 
than vandyke brown, under parts between light bistre and raw umber). 
Size.tf adult, length (skins), 143-149.5 ; wing, 77-82.5; tail, 64.5-68.5; 
exposed culmen, 17.5-18.5; depth of bill at base, 15.5-16.5; width of

Type from Santa Marta, Colombia, No. 5371, $ adult, coll. of E. A. 
and O. Bangs. Collected Jan. 15, 1898, by W. W. Brown, Jr. 
Subspecific characters. Smaller than A. conirostris; wings and tail 
darker, more dusky, less greenish ; back much grayer, the feathers 
tipped and edged with gray ; nape and head between the black stripes 
clear gray without any olive or greenish. 
Size. tf adult, wing, 76.2; tail, 64.6; exposed culmen, 14; 9 adult, 
wing, 66; tail, 57; exposed culmen, 14. 
Remarks. A. conirostris canens differs so much in color from true A. co 
nirostris besides being considerably smaller, that it may prove to be a dis 
tinct species, though for the present I prefer to treat it as a subspecies. 
Saltator magnus (Gmel.)

one Santa Marta specimen differs from birds from that region in having 
yellow instead of white throat, being richer in color throughout and in 
having a shorter wing. Should other specimens bear out these charac 
ters, then the Santa Marta bird must be separated as a subspecies.

Specific characters. ^, size rather small (about the size of P. hxmalea) ; 
tail long; bill very small, much smaller than that of P. hssmalea or P. 
testacea, and not so swollen ; tooth on edge of upper mandible very prom 
inent; upper parts deep brownish red, more intense (shading towards 
dark carmin ) on head ; wings dusky, the feathers edged with dark red, 
without wing bars ; under parts bright orange vermilion, browner on 
flanks and more scarlet on throat ; 9 slightly smaller than the $ ; colors

above deep olive green, sides of forehead more yellow ; below bright 
olive yellow, shaded with olive on sides and flanks.

bill at nostril, 8.2. 9 adult, wing, 85.8; tail, 72.6; exposed culmen, 16; 
breadth of bill at nostril, 8.2. 
Remarks. On Feb. 4, 1898, Mr. Brown took a pair of this beautiful new 
tanager, the female at 4000 ft. and the male at 3000 ft. P. faccta scarcely 
needs comparison with any other form, its bright orange vermilion under 
parts and small bill at once distinguishing it from P. testacea or P. hsemalea.

lype from Santa Marta, Colombia, No. 5462, <^ adult, coll. of E. A. and 
O. Bangs. Collected Jan. 28, 1898, by W. W. Brown, Jr. 
Subspecific characters. Similar to true C. flavipectus of Trinidad, but 
slightly smaller ; wing shorter ; color of throat and breast much purer, 
deeper, more golden, less greenish yellow, being in C. canticus nearly pure 
canary yellow. 
Size. $ adult, wing, 75.2; tail, 58; exposed culmen, 17. 9 adult, 
wing, 72.4; tail, 61; exposed culmen, 16.6. 
Remarks. This is the form over which there has been so much discus 
sion. Count Von Berlepsch, Ibis, 1888, p. 85, first noticed the differences, 
saying "specimens of C. flavipectus from Bogota generally show a much 
purer and deeper golden yellow on the under parts than those from Ven 
ezuela and Trinidad." Santa Marta skins seem even more strongly to 
show these differences than Bogota skins. Dr. J. A. Allen, in Bull. Am. 
Mus., Vol. II, p. 130, June, 1889, renamed the Trinidad bird, calling it 
C. flavipectus trinilatis. Mr. Frank M. Chapman, when he corrected this 
mistake in his list of Trinidad birds, Bull. Am. Mus., Vol. VI, p. 27, 18 ( J4, 
referred the Colombia birds to the Costa Rican form C. subflavescens, from 
which they appear to me to be perfectly distinct.

Ti/pe from Santa Marta, Colombia, No. 5478, cT adult, coll. of E. A.

Specific characters. Adult $, about the size of D. coerebicolor or rather 
larger; wing about the same or longer; bill much larger longer and 
stouter; color pattern the same; the blue color an intense cobalt blue, 
very different from the dark purplish blue of D. coerebicolor ; feet flesh 
color. 
Size. c? adult, wing, 69 ; tail, 47 ; exposed culmen, 7.6. 
Remarks. D. napxa needs comparison with but one species, D. coerebi 
color. This comparison I have been able to make, the National Museum 
having a considerable series of Bogota skins. The very large bill and 
bright blue color of D. napxa mark the Santa Marta bird as specifically 
distinct from the small-billed dark purplish blue D. coerebicolor of Bogota.

Type from Santa Marta, Colombia, No. 5560, 9 adult, coll. of E. A. 
and O. Bangs. Collected Jan. 22, 1898, by W. W. Brown, Jr. 
Specific characters. Size rather small; sexes alike; bill yellow above 
and below, darker at base ; no eye stripe ; 4th and 5th primaries nearly 
equal and longest, 3rd and 6th nearly equal, next, 2nd and 7th equal ; 
legs, feet and claws pale brownish ; color above uniform rich olive brown, 
including lores, ear-coverts, tail and wings, except primaries and inner 
webs of secondaries, which are more dusky ; below, breast and sides 
olivaceous wood brown; center of belly and under tail-coverts clear buff; 
throat dull whitish with pale olive brown streaks; under wing-coverts 
dull orange buff. 
Size. 9 adult, wing, 112.6; tail, 91; exposed culmen, 20. $ adult, 
wing, 114.6; tail, 92.6; exposed culmen, 19.8. 
Remarks. The Santa Marta thrush is most like M. gymnophthalmus in 
general coloration, but can be told from that species by not having the 
naked eye spots and the under tail-coverts not being streaked. The only 
other species that it needs to be compared with is M. ignobilis, from which 
its smaller size, yellow bill, and many differences in detail of coloration 
at once distinguish it.
