youngest of these (No. 480, ♂?, Camp Lowell, June 2), although well

feathered, has the wings and tail undeveloped, and was taken from the

nest. Its entire upper plumage is rusty brown with a chestnut tinge

which deepens on the rump and outer webs of the secondaries to decided

chestnut brown. The general coloring of the under parts is pale

fulvous with a strong tinge of rusty chestnut across the breast, along

the sides, and over the anal region and crissum. The breast is

obsoletely spotted, but the plumage elsewhere, both above and below,

is entirely immaculate. An older bird (No. 577, Camp Lowell, June 23)

with the wings and tail fully grown out, differs in having the back

(excepting a narrow anterior space bordering on the nape), with the

exposed webs and coverts of the wings, and a broad tipping on the tail

feathers, bright rusty;—while in a third of about the same age (No.

614, ♂, Camp Lowell, June 28), the rusty color, although paler, is

uniformly distributed over the entire upper surface save upon the

wings and tail feathers, which are only edged and tipped with that

color. This last example is so faintly marked beneath that the plumage

at first sight appears immaculate; but a closer inspection reveals a

few spots here and there among the central feathers of the breast. A

fourth (No. 487, Camp Lowell, June 3), although apparently no older,

has the breast and sides spotted more sharply than in any of the

adults, while the rusty tinge above is chiefly confined to the rump,

posterior half of the back, and the outer webs of the wing feathers.

Several of these young birds are so nearly similar to specimens of _H.

bendirei_ in corresponding stages that they can be separated only with

great difficulty. The stouter bill and entirely black lower mandible

of _palmeri_ may, however, always be depended upon as distinguishing

characters; and, moreover, the pectoral spotting of _bendirei_ is

usually (but not invariably) finer and sharper, and the rusty tinge

above paler and less extended.

The adults present a good deal of variation, most of which is

apparently seasonal. Winter specimens have the lower abdomen, with the

anal region and crissum, rich rusty-fulvous, while the markings

beneath are similar in character to those of true _curvirostris_, and

the spots equally distinct, numerous and widely distributed. With the

advance of the season, and the consequent wear and tear of the

plumage, the spots gradually fade or disappear. Indeed some of the

June specimens are absolutely immaculate beneath, although most of

them, like Mr. Ridgway’s types, have a few faint markings on the

abdomen. In this condition the general coloring is also paler and

grayer, and the fulvous of the crissum and neighboring parts often

entirely wanting.

But although the evidence of this series tends to demolish several of

the characters upon which _palmeri_ has been based, enough remain to

separate it from its ally the true _curvirostris_ of Mexico and the

Rio Grande Valley in Texas. The best of these, perhaps, is to be found

in the different marking of the tail feathers. In _curvirostris_ the

three outer pairs are broadly tipped with pure white which, on the

inner web, extends twice as deep, basally, as on the outer one, and

has its boundaries everywhere sharply defined; in _palmeri_ the outer

rectrices are, at the most, barely tipped with pale brown, which

either extends squarely across both webs, or fades insensibly into the

darker color of the feather. The bill of _palmeri_, also, is usually

longer and more curved than that of _curvirostris_.

8. =Harporhynchus lecontei= _Bonap._ LECONTE’S THRASHER.—The great

rarity of Leconte’s Thrasher, even in the heart of the desolate regions

where alone it has so far been found, is still further attested by Mr.

Stephens’ experience during the past season, for although he searched

for it carefully in all suitable places between Camp Lowell and

Riverside (California), he met with only two individuals. These occurred

about fifteen miles west of Maricopa, Arizona, in a locality which the

accompanying notes describe as follows: “Near the middle of

‘Forty-five-mile Desert,’ between Maricopa Wells and Gila Bend. No

chollas or other cactuses in the immediate neighborhood, but some giant

cactuses about a mile away in the hills; a few mesquites and much

scattering low brush in the vicinity; nearest water twenty miles away.”

Dr. Cooper is said to have found the species “rather common” in the

desert between Fort Mohave and the San Bernardino Mountains, California,

but Mr. Stephens has thrice traversed this route without seeing a single

specimen. In a recent number[42] of the American Naturalist, however,

Mr. E. Holterhoff, Jr., speaks of seeing the bird “on the Colorado

desert, at a station called Flowing Wells,” and gives an interesting

description of a nest and set of eggs taken there. “The nest was placed

in a palo verde tree, and was a very bulky affair, measuring externally

nine inches in depth and six in width; the hollow of the nest was fully

three inches in depth. It was so awkwardly situated that much of the

base of the nest had evidently been filled in to firmly support the

structure. The two eggs were somewhat smaller than those of _H.

redivivus_, lighter in color, and marked all over with finer reddish

spots, thicker at the larger end.”

I am inclined to consider the Maricopa specimens above referred to as

adults, although this is not so clear in the case of the male, portions

of whose plumage suggest that of a young bird. Both are in worn, ragged

condition, but there is no indication of any moult, save upon the wings

and tail, where many of the feathers have been replaced by new ones

which are conspicuous among the others by their fresher coloring.

On a former occasion[43] I urged the specific distinctness of this

Thrasher from _H. redivivus_, and to this conviction I still hold,

although a comparison of additional specimens of both species inclines

me to believe with Dr. Coues that Leconte’s Thrasher is, on the whole,

more nearly related to _redivivus_ than to any other United States form.

616, ♂ ad., near Maricopa Wells, July 5. Length, 10.80; extent, 12.30;

wing, 3.85; tarsus, 1.27; tail, 5.35; culmen (chord), 1.30; bill from

nostrils, .91; width below posterior angle of nostrils, .23.

617, ♀ ad., same locality and date. Length, 10.60; extent, 12; wing,

3.78; tarsus, 1.32; tail, 4.91; bill (chord of culmen), 1.32; bill from

nostril, .94; width below posterior angle of nostril, .24. “Iris

reddish-brown; bill black; legs nearly black. Stomach contained a small

species of katydid and some ants.”

9. =Harporhynchus crissalis= _Henry_. CRISSAL THRASHER.—Not uncommon

near Tombstone, Tucson and Camp Lowell.

Dr. Coues, comparing this species with Le Conte’s, Palmer’s, and

Bendire’s Thrashers, concludes:[44] “and we are led to infer that when

the ‘topography’ of the other three species is fully determined, it will

be found no less extensive. For there is nothing peculiar in the economy

or requirements of any one of the four in comparison with the rest.”

This view, however, is hardly supported by the testimony of observers

who have had the best opportunities of studying these birds. The Crissal

Thrasher, according to Captain Bendire,[45] “appears to prefer damp

localities near water-courses, and confines itself principally to spots

where the wild currant is abundant.” Mr. Henshaw says: “According to my

experience, it is not a bird of the plains, but inhabits by preference

the rough sides of rocky cañons or the hillsides covered with broken

_débris_, interspersed with straggling bushes.” Mr. Stephens’ evidence

is not less explicit. He found the Crissal Thrasher in copses in

valleys, and along streams. It was especially fond of well-shaded

undergrowth, and spent much of its time on the ground, searching for

food under the bushes. It never occurred among cactuses, and the only

place where he saw it actually associating with Bendire’s and Palmer’s

Thrashers, was at Camp Lowell, where the latter species, with other

desert birds, came to drink at a water-hole and thus occasionally

mingled with the Crissal Thrashers which inhabited the neighboring

thickets. The contrast which these traits afford when compared with the

ones characterizing the other three species named by Dr. Coues, is

sufficiently apparent.[46]

A nest received from Mr. Stephens is precisely similar to those found by

Captain Bendire. The three eggs which it contained measure respectively,

1.14×.76, 1.14×.75, and 1.08×.77. Like all the specimens which have been

previously reported they are entirely unspotted, and both in size and

color closely resemble eggs of the common Robin.

_Juv., first plumage_ (♀, No. 546, Camp Lowell, June 20). Above

dull reddish-brown. Rump and a broad tipping on the tail,

brownish-chestnut. Under parts nearly uniform, brownish-fulvous.

Crissum chestnut, of nearly the same shade as in the adult.

Maxillary stripes dusky brown. No trace of spots or other dark

markings either above or beneath.

Five other young birds in the series are essentially similar and call

for no special comment. I cannot find any description of the first

plumage of either _H. redivivus_ or _H. lecontei_, but with the

exception of these, _H. crissalis_ is the only North American species

in the sub-family _Miminæ_ whose young are entirely unmarked beneath.

It is interesting to note that with respect to the color of the upper

parts, especially that of the rump, they resemble the young of both

_H. bendirei_ and _H. palmeri_.

The individual variation presented by the adults before me is chiefly

confined to the relative length and curvature of the bill, the general

coloring of all being nearly uniform, although the breeding birds are

slightly paler than those taken early in the season.

“Iris light brown. Stomach contained insects and a _small lizard_.”

251, ♂ ad., Tucson, April 21. Length, 12.60; extent, 12.60; wing,

extent, 12.20; wing, 3.73; tail, 5.65; culmen, 1.42.

10. =Cinclus mexicanus= _Swains._ AMERICAN WATER OUZEL.—The following

notes relate to the only specimen met with:

“My attention was called to the song of some bird which came from the

mountain brook running past camp. There was a steep, rocky wall on the

further side, and the notes echoing from it, and mingling with the

purling of the water, sounded exquisitely sweet. On looking for the

author, I noticed some ripples rolling out from behind the willows that

fringed the nearer shore, and soon discovered an Ouzel dabbling in the

shallow water. My shot wounded the bird, but did not disable its wings,

for it repeatedly dived, using them as propelling agents when beneath

the surface. The sun shining on the air-bubbles that clung to its

plumage made it look like a ball of silver flying through the water. On

the surface it paddled along very much in the manner of a Phalarope.”

79, ♂ ad., Morse’s Mill, Chiricahua Mountains, March 20. Length, 7.90;

extent, 12.10; wing, 3.85; tail, 2.50. “Iris hazel. The flesh was dark

and tough with a fishy smell. The inside of the skin looked like that

of a small Wader. Stomach contained insects.”

11. =Sialia mexicana= _Swains._ WESTERN BLUEBIRD.—A single pair, taken

in the Chiricahua Mountains in March, are accompanied by the note,

“abundant in all kinds of timber.”

12. =Sialia arctica= _Swains._ ARCTIC BLUEBIRD.—This species is noted as

“rare in the low valleys” among the Chiricahua Mountains. A small flock

was also seen near Galeyville on “grassy plains,” where “they flew from

one weed-stalk to another.” They were “restless and rather shy.” The

single specimen obtained was shot on this latter occasion.

13. =Myiadestes townsendi= (_Aud._) _Caban._ TOWNSEND’S SOLITAIRE.—Three

specimens were obtained in the Chiricahua Mountains, where they occurred

sparingly among piñons. “They are rather tame, and have a habit of

sitting perfectly still for several minutes at a time. Flight slow. Food

insects.” A fourth, taken May 13, in the Santa Rita Mountains, completes

the series.

14. =Phaïnopepla nitens= (_Swain._) _Scl._ BLACK-CRESTED FLYCATCHER.—The

life history of this singular bird has been so fully given by Dr. Coues

in “Birds of the Colorado Valley,” that there is little chance of adding

anything new. Most of the specimens obtained by Mr. Stephens are from

Camp Lowell and Tucson, but he did not find it abundant at either of

these points. He speaks of it as having “a sweet but not loud song,” and

remarks on its known fondness for mistletoe berries. “Iris red.”

15. =Polioptila cærulea= (_Linn._) _Scl._ BLUE-GRAY GNATCATCHER.—Eight

specimens, representing the following localities: Chiricahua Mountains

(two ♂, two ♀, April 1–6); Tombstone (♂, April 5); Cienega Station (♂,

April 16); Tucson (♂, April 20); Santa Rita Mountains (♂, May 20).

16. =Polioptila plumbea= _Baird_. BLACK-CAPPED GNATCATCHER.—This

Gnatcatcher was observed at Tucson, Camp Lowell, and near Yuma,

specimens being taken in all these localities. A female shot at the

first-named point on April 23 had evidently finished laying, but a nest

found June 27 near Camp Lowell contained a perfectly fresh egg, while

another taken at Yuma, July 15, had a single egg of its owner and one of

the Dwarf Cowbird. These dates indicate that the species breeds at least

twice during the season.

The Yuma nest, although a delicate structure, will not compare with that

of _P. cærulea_. It entirely lacks the exterior coating of lichens so

effectively employed by the commoner bird, and in its general appearance

closely resembles the Redstart’s well-known domicile, being similarly

felted of soft bark strips and hemp-like vegetable fibres. It is lined

with down from plants, a few feathers, and the hair of some small

quadruped. Externally it measures 2.25 in width by 1.55 in depth;

internally 1.45 by 1. The egg is pale greenish-blue, coarsely and very

evenly spotted with reddish-brown. Its measurements are .53×.42. This

nest was placed in a bunch of mistletoe, at a height of about eight feet

from the ground. It is accompanied by the male parent, who revealed its

position by repeatedly entering the mistletoe. and showing other signs

of anxiety respecting its contents. The position of the Camp Lowell nest

is not mentioned.

_Juv., first plumage_, ♀ (No. 619, Yuma, July 15). Crown pale

cinereous; rest of upper parts faded brown. The wings are uniform with

the back, but all the primaries and secondaries have a broad white

edging on their outer webs. The tail is dull black, with white areas

on the outer rectrices corresponding in extent and purity with those

of the adult. Beneath, pale ashy-white.

A study of the large series of Gnatcatchers collected during the past

season confirms the views which I lately advanced (this Bulletin, Vol.

VI, p. 101) regarding the affinity of _P. plumbea_ and _P.

“melanura,”_ and also affords additional evidence of the assumed

specific distinctness of _P. californica_. The Yuma examples of _P.

plumbea_ are quite as typical as those taken at Tucson and Camp

Lowell, while seven specimens of _californica_, collected at Riverside

after Mr. Stephens’ return to that place, still further attest the

constancy of most of the characters which I assigned to the latter

bird. That relating to the brown edging of the secondaries will,

however, have to be abandoned, for _plumbea_ proves to be similarly

characterized when in worn breeding dress; the supposed shorter tail

of _californica_ also is now shown to be an inconstant feature. All of

the three young males taken at Riverside have black lateral

crown-stripes like those of immature _plumbea_.

267, ♂ ad., Tucson, April 23. Length, 4.60; extent, 5.80; wing, 1.85;

tail, 2.15; bill (from nostril) .25; tarsus, .67. “Iris dark brown;”

of head ashy-white; ill-defined, black, lateral crown-stripes

partially concealed.

tail, 2.21; bill (from nostril), .27; tarsus, .68. “Had just finished

laying.”

1.86; tail, 2.13; bill (from nostril), .26; tarsus, .68.

601, ♀ ad., Camp Lowell, June 27. Length, 4.60; extent, 5.50; wing,

1.74; tail, 2.18; bill (from nostril), .27; tarsus, .70. “Taken with

the nest and one fresh egg.”

619, ♀ juv., first plumage, Yuma, July 15. Length, 4.40; extent, 5.60;

wing, 1.86; tail, 2.12; bill (from nostril), .26; tarsus, .70.

5.60; wing, 1.85; tail, 2.22; bill (from nostril), .27; tarsus, .68.

For comparison I add measurements of the seven specimens of _P.

californica_ above mentioned.

656, ♂ juv., fall plumage, Riverside, Sept. 16. Length, 4.55; extent,

5.70; wing, 1.67; tail, 2.20; bill (from nostril), .29; tarsus, .75.

.75.

688, ♂ juv., fall plumage, Riverside, Sept. 23. Length, 4.50; extent,

5.75; wing, 1.86; tail, 2.15; bill (from nostril), .28; tarsus, .75.

17. =Regulus calendula= (_Linn._) _Licht._ RUBY-CROWNED KINGLET.—“Common

among the Chiricahua Mountains, especially in deciduous timber. I think

a few summer and breed.” The following specimens are identical with

eastern ones:

28, ♂ ad., Cave Creek, Chiricahua Mountains, March 8. Length, 4.60;

extent, 6.50; wing, 2.32.

122, ♂ ad., Morse’s Mill, March 28. Length, 4.20; extent, 6.90; wing,

2.38.

18. =Lophophanes inornatus= (_Gamb._) _Cass._ PLAIN TITMOUSE.—Mentioned

in Mr. Stephens’ notes as rare on the foot-hills of the Chiricahua

Mountains, but no specimens are included in his collection.

19. =Lophophanes wollweberi= _Bonap._ WOLLWEBER’S TITMOUSE.—This species

was abundant in the Chiricahua Mountains, where a fine series was

collected. They were usually seen in flocks of six or eight, and often

associated with other small birds. They were rarely met with excepting

in the groves of “scrub oaks,” but their food appeared to be wholly

insects. A single pair taken in the Santa Rita Mountains in May are

unaccompanied by any special remarks.

20. =Parus meridionalis= _Scl._ MEXICAN CHICKADEE.—In a late number of

the Bulletin (Vol. VI, p. 252) I briefly announced this important

addition to the North American fauna. The series obtained by Mr.

Stephens comprises nine specimens, all of which were taken near Morse’s

Mill. They occurred upon the sides or summits of the surrounding

mountains, at elevations varying from seven to ten thousand feet, and

were usually found in pairs, although they not unfrequently associated

with other birds, among which are mentioned _Psaltriparus plumbeus_,

_Lophophanes wollweberi_, _Sitta pygmæa_, and _Peucedramus olivaceus_.

They were for the most part silent, but occasionally uttered a

“_chee-wee-wee_,” as well as notes resembling those of _P. montanus_.

Previous writers have compared this species with _P. atricapillus_, but

to me it seems nearer related to _P. montanus_. With the latter it

agrees in certain peculiarities of size and proportions, while the

general coloring and markings of the two are so similar that almost the

only appreciable points of difference are presented by the white

forehead and head-stripes of _montanus_. These characters are, of

course, enough to instantly separate the birds, but their importance is

somewhat weakened by the fact that one of my specimens of _meridionalis_

(No. 124) possesses a head-stripe which, though ill-defined and

considerably shorter, is nevertheless similar in appearance and position

to that of _montanus_. While it would be rash to argue any varietal

affinity on the strength of this single specimen, the outcropping of

such a well-marked characteristic certainly shows a close relationship

between the two species, unless indeed No. 124 be regarded as a hybrid.

65, ♂ ad., Morse’s Mill, March 18. Length, 5.20; extent, 8.50; wing,

2.74; tail, 2.60. “Iris dark brown. Stomach contained insects.”

82, ♀ ad., Morse’s Mill, March 21. Length, 5.10; extent, 8.10; wing,

2.73; tail, 2.62.

2.90; tail, 2.69.

2.85; tail, 2.68.

125, ♂ ad., same locality and date. Length, 5; extent, 8.20.

21. =Psaltriparus plumbeus= _Baird_. LEAD-COLORED TIT.—Of the eight

specimens of this species which are included in the collection, seven

were taken in the Chiricahua Mountains, the remaining one being from the

Santa Rita Mountains. Mr. Stephens does not appear to have found it

elsewhere, and in his notes characterizes it as rather uncommon. It was

oftenest seen among the oaks of the foot-hills, where it associated with

Wollweber’s Titmouse, the Ruby-crowned Kinglet, and several other small

birds.

22. =Auriparus flaviceps= (_Sundev._) _Baird_. YELLOW-HEADED TIT.—Mr.

Henshaw while in Arizona met with but few specimens of this curious

little species. He attributed their apparent rarity to the lateness of

the season at which his observations were made, and doubtless this

explanation is the true one; for during the past spring Mr. Stephens

found them in abundance both at Cienega Station and Tucson. Nevertheless

it is probable that some individuals pass the winter in Arizona, for one

of my specimens is dated November 29, and another was killed early in

March. A nest taken at Tucson contained three fresh eggs on April 20.
