_Voice._--We hear the voice of the cuckoo much oftener than we

see the bird; the well-known sound comes to us, like a wandering

voice, from the depths of some shady retreat, but we cannot see

the hidden author. We can recognize it easily as the voice of

a cuckoo, but it is not always so easy to identify the species

by its notes, though some keen observers claim that they can do

so. Certain songs are characteristic of each of the two species,

but both have a great variety of notes and many notes that are

much alike in both. The notes of the yellow-billed cuckoo may be

a trifle harsher and a little louder, but they are not always

recognizable. The characteristic note of the yellow-billed

cuckoo is well described by Charles J. Spiker (1935) as follows:

“What may be considered the song of this species is a series

of rapid, wooden-sounding syllables resembling the following:

_Kuk-kuk-kuk-kuk-kuk-ceaow-ceaow-ceaow-ceaow_; the _kuks_ being

given rapidly, the _ceaows_ more deliberately and with longer

intervals.”

Bendire (1895) writes:

One of their commonest notes is a low “noo-coo-coo-coo;”

another sounds more like “cow-cow-cow” or “kow-kow-kow,”

several times repeated; others resemble the syllables of

“ough, ough, ough,” slowly and softly uttered; some remind

me of the “kloop-kloop” of the Bittern; occasionally a note

something like the “kiuh-kiuh-kiuh” of the Flicker is also

uttered; a low sharp “tou-wity-whit” and “hweet hwee” is

also heard during the nesting season. Though ordinarily not

what might be called a social bird, I have sometimes during

the mating season seen as many as eight in the same tree,

and on such occasions they indulge in quite a number of

calls, and if the listener can only keep still long enough

he has an excellent opportunity to hear a regular Cuckoo

concert.

Various other interpretations of the different notes have been

given by other writers, but the above quotations cover fairly well

the ordinary variations. The song, as given by Mr. Spiker above, is

sometimes more prolonged by lengthening the series of _kuks_, with

increasing speed of utterance and adding to the series of _ceaows_,

with slowly decreasing speed. I believe that the black-billed

cuckoo never gives this prolonged song, accelerated during the

first half and retarded during the last half; its song is given

in more even time, and is generally shorter. The song of the

yellow-billed cuckoo is often heard during the night, and its notes

are often uttered while flying.

_Field marks._--A cuckoo may be easily recognized as a cuckoo by

its size, shape, and color--a long, slender bird, longer than a

robin, with a long tail, olive-brown above and white below; but the

two species look very much alike unless the distinctive markings

can be clearly seen. The yellow lower mandible of this species can

be seen only at short range. But the rufous in the wing feathers is

evident in flight, and the lateral tail feathers are conspicuously

black, with large terminal white areas clearly defined. At very

close range the yellow eyelids of this species may be seen.

DISTRIBUTION

_Range._--Temperate North America, the Caribbean region, South and

Central America; casual on Bermuda and accidental in western Europe.

_Breeding range._--The breeding range of the yellow-billed

cuckoo extends =north= to southern British Columbia (Kamloops);

northeastern Oregon (Keenys Ferry); northern Utah (Salt Lake City);

northern Colorado (Loveland, Greeley, and Fort Morgan); South

Dakota (White River, Yankton, and Sioux Falls); Minnesota (Fosston

and St. Paul); Wisconsin (Ladysmith, Waupaca, and New London);

northern Michigan (Blaney and Sault Ste. Marie); southern Ontario

(Listowel, Rosseau, and Ottawa); northern New York (Watertown

and Plattsburg); and southern Maine (Auburn). From this point

the breeding range extends southward along the Atlantic coast to

Florida (New Smyrna and Kissimmee); the Bahama Islands (Inagua

Island); probably the Dominican Republic (Dajabon); and the Virgin

Islands (St. Croix). =South= to the Virgin Islands (St. Croix);

Jamaica (Port Henderson); Coahuila (Sabinas River); southern Sonora

(Guaymas); and southern Baja California (San Jose del Rancho).

=West= to Baja California (San Jose del Rancho and Cerro Prieto);

California (Wilmington, Watsonville, Santa Clara, and Redding);

Oregon (Salem); Washington (Grays Harbor, Tacoma, and Seattle); and

British Columbia (Victoria, Chilliwack, and Kamloops).

The range as outlined is for the entire species, which has been

separated into two geographic races. The yellow-billed cuckoo (_C.

a. americanus_) occupies the eastern part of the range west to

South Dakota, Nebraska, eastern Colorado, and Oklahoma, while the

California cuckoo (_C. a. occidentalis_) is found over the rest of

the country to the Pacific coast.

_Winter range._--The winter home of this species has not been

accurately determined, but it extends =north= to northern Colombia

(Santa Marta, Bonda, Medellin, and Antioquia); and Venezuela (San

Cristobal, Altagracia, the Orinoco River region, and Nericagua). It

has been found at this season =east= to southeastern Brazil (São

Paulo); Uruguay (Rio Negro); and eastern Argentina (Buenos Aires

and Lomas de Zamora). =South=, probably only casually to central

Argentina (Lomas de Zamora and Saladillo). =West= to Argentina

(Saladillo and La Riojo); Ecuador (Nono, Chimbo, Cumbaya, and

Guapulo); and Colombia (Cienaga and Santa Marta).

_Casual records._--While the yellow-billed cuckoo may be considered

only as a casual visitor to Bermuda, an extraordinary invasion

was recorded on October 9, 1849, when thousands of individuals

suddenly appeared in all parts of the island; a few more have been

subsequently reported. During the period from 1825 to 1921 it was

recorded fully a dozen times from England, Scotland, Ireland,

and Wales, all these occurrences being in fall and mostly during

October. One was taken at Bois de Lessines, Belgium, in October

1874, and one was collected at Turin, Italy, on October 28,

1883. Two occurrences have been recorded from the southern part

of France, but there is some question that they were correctly

identified.

CALIFORNIA CUCKOO

PLATE 6

HABITS

This western race of our common yellow-billed cuckoo has been

separated on very slight average characters, hardly worthy of

recognition in nomenclature. I am inclined to agree with Harry S.

Swarth (1929), who says:

Between the eastern and western races of the Yellow-billed

Cuckoo there is a slight average difference in size,

the western bird being the larger and with a somewhat

heavier bill. There is a rather wide range of variation

in specimens from any one locality, * * * and the largest

eastern birds do not fall far short of the maximum

measurements of western specimens. Birds from the Pacific

coast are the largest, those from central Arizona near the

type locality of _occidentalis_ (the Santa Rita Mountains)

are intermediate in size. The subspecies would have a

better claim to recognition if restricted to the Pacific

coast. * * * The subspecies is certainly as slightly

differentiated as any in our _Check-list_, and I feel that

no violence to the facts would result from suppression of

the name.

The California cuckoo is nowhere abundant but seems to be generally

distributed, in suitable localities, throughout its range from

British Columbia to Lower California and other parts of Mexico.

In southern California, its favorite haunts seem to be the willow

thickets and groves along the beds of streams, or in willow-bottom

sloughs, such as the famous Nigger Slough, which formerly existed

near Los Angeles. Alfred C. Shelton (1911) describes a favorite

haunt in Sonoma County, Calif., as follows: “In the locality of

which I write, about five miles southeast of Sabastopol, this

stream, known locally as the ‘Lagoon’, becomes, after some winter

storm, a turbulent river, flooding acres upon acres of bottom

land. In summer its course is marked by a chain of long, rather

narrow ponds, many of which are deep. The banks, and much of the

intervening space between these ponds, are covered with a thick

growth of willow, small ash and scrub oak, while the whole is

tangled together with an undergrowth of poison oak, wild blackberry

and various creepers, forming, as it were, an impenetrable jungle,

hanging far out over the water.”

_Spring._--Mr. Shelton (1911) has this to say about the spring

movements of the California cuckoo:

Of all migratory birds breeding in this vicinity, the

Cuckoo is the last to arrive in the spring, usually

appearing during the latter part of May or the first week

of June. Upon its arrival, this bird keeps to the higher

land, among the oaks and other timber, for a period of

two or three weeks before retiring to the willow bottoms

to breed. During this period it is wild and shy and

difficult to approach. Most active in the early morning,

its characteristic note, a loud, clear “kow-kow-kow,” may

be heard coming from some tree or group of trees, and

perchance an answering “kow-kow-kow,” may come from another

tree, some distance away. * * *

After the birds retire to the willow bottoms to breed,

their entire attitude changes. When watched and studied in

the seclusion of their brush grown haunts, while engrossed

with the cares of their domestic duties, the Cuckoos

cease to be the wild, shy birds of the upland timber. The

familiar “kow-kow-kow” is now forsaken for another note,

a low guttural note, “kuk-kuk-kuk,” always uttered by a

brooding bird and is the most common call of the cuckoo

during the breeding season.

_Courtship._--J. H. Bowles (Dawson and Bowles, 1909) writes: “While

standing in an open woodland listening to a pair of Cuckoos calling

to each other, I saw the male suddenly fly past with a large green

worm in his bill. He flew directly to the female, who was perched

in a tree a few yards distant, and for a moment or two they sat

motionless a few inches apart looking at each other. The male

then hovered lightly over his mate and, settling gently upon her

shoulders, gracefully bent over and placed the worm in her bill. It

was a pretty and daintily performed piece of love-making.”

_Nesting._--The nesting habits of the California cuckoo are much

like those of its eastern relative. In California its favorite

nesting sites are in willow thickets in the river bottoms, or in

such swampy lowlands as those referred to above. D. E. Brown writes

to me that it is a rare bird in western Washington, and says: “It

is found mostly in willow swamps, on the shores of fresh-water

lakes, and along streams where the underbrush is thick. I have

seldom seen it very far away from fresh water and never in real

thick woods. It is a late arrival and does not begin nest building

until about the fourth of July. I have found about a dozen occupied

nests and only one of these was earlier than the above date; this

one was on June 19. All these nests were in willow or wild-rose

bushes, except one which was in a spirea bush. All nests were 2 to

8 feet from the ground, or water when built in swamps. The nest is

a very frail, small affair composed of twigs loosely put together

and lined with finer twigs and sometimes a few leaves. Most of the

nests that I have seen have been so very flat and small that they

would be exceedingly hard to find if the birds were not on them.”

A nest in the Thayer collection, taken near Kirkland, Wash., on

July 7, 1909, was found in an open space in a fir forest in low

ground, which was dotted with a second growth of fir and some

_Osmaronia_ and _Spiraea_; it was placed on a branch of a fir on

the exposed side of the tree, 9 feet from the ground; it was made

of old fir twigs and lined with fresh fir twigs. I have heard of

other Washington nests in fir trees.

Major Bendire (1895) says:

The nests here [Arizona] were placed in willow or mesquite

thickets, from 10 to 15 feet from the ground, and they were

usually fairly well concealed by the surrounding foliage.

* * * If the California Cuckoo showed the same parasitic

habit of occasionally depositing one or more of its eggs in

the nests of other birds, as its eastern relatives are now

and then known to do, I believe that I should have observed

the fact in southern Arizona. Here I found eight of their

nests with eggs, and fully five hundred nests of smaller

birds, which nested in similar localities among the willow

thickets and mesquite bushes, overrun with vines, in the

creek bottoms, but not a single instance of parasitism came

under my observation.

Wilson C. Hanna (1937) has published an interesting paper on the

nesting habits of the California cuckoo in the San Bernardino

Valley, Calif., with a photograph of a nest containing the unusual

number of seven eggs; he writes:

I have rather complete notes on twenty-four nests that

I have examined in the field, six along Warm Creek and

eighteen along the Santa Ana River, and with two exceptions

all were in willow trees. In one case the nest was 11 feet

up in an alder tree next to the trunk, and in the other

case 30 feet up in a cottonwood tree on top of a bare limb

partly supported by a few twigs and therefore conspicuous.

The last mentioned nest was ten feet higher than any

other nest I have seen. Six of the nests in willows were

either partly supported by or covered with wild grape

vines, another nest was well concealed in the center of

live mistletoe, while still another was well hidden in

poison oak that was growing over the dead willow tree. A

few nests were placed next to the trunks of trees, but by

far the most common location was well out on a horizontal

or leaning limb. The average height above ground or water

was less than thirteen feet and two were only four feet

up. A good supply of rope and a ladder were necessary for

examining some of the nests without disturbing them or the

surroundings.

Nests were always loose structures, of coarse twigs for a

foundation, sometimes with a little superimposed grape-vine

bark, cottonwood bark, or rootlets. In some cases there was

no other lining and eggs could be seen through the bottom

of the nest; but usually there were fresh or old leaves,

bark strips, or willow cotton. In only one nest was there a

feather in the lining. Often the nests were much longer in

one dimension than the other, in one case four inches wide

and twelve inches long.

_Eggs._--The California cuckoo lays usually three or four eggs,

occasionally only two. These are indistinguishable from those of

the eastern yellow-billed cuckoo and average only slightly larger.

The measurements of 43 eggs average 31.1 by 23.1 millimeters; the

eggs showing the four extremes measure =35.5= by 23.5, 33.5 by

=25=, and =27.5= by =21= millimeters.

_Food._--Bendire (1895) says that in a brood that he watched, the

young were fed “always with a large black cricket (_Anabus simplex_

or _purpuratus_) * * *. They picked most of these repulsive-looking

creatures from grass stalks and low shrubs on which they were

feeding, and although there were numbers of them to be found all

around, as well as in camp, they generally went off some little

distance to get them.”

Mr. Swarth (1929) says that a female, collected in Arizona,

“contained in its stomach two green caterpillars and a lizard 100

millimeters long, the latter swallowed entire and rolled into a

coil. This seems a startling diet for a tree-dwelling cuckoo,

but there is at least one other instance reported, also from the

vicinity of Tucson, of a lizard being taken by one of these birds.”

BLACK-BILLED CUCKOO

PLATES 8–11

HABITS

The black-billed cuckoo is not so widely distributed as the

yellow-billed, being confined in the breeding season to practically

the northern half of the United States and southern Canada east

of the Rocky Mountains. Within this range it seems to be commoner

northward and rarer southward than the other species, ranging

farther north and not so far south.

In appearance and habits our two cuckoos are very much alike,

and their haunts are similar; both are often found together, or

in similar places, though the black-billed is rather more of a

woodland bird and rather more retiring than the yellow-billed.

William Brewster (1906) says that in the Cambridge region it is

“more given to haunting extensive tracts of dry upland woods and

to nesting in wild apple trees, Virginia junipers and barberry

bushes in remote rocky pastures such as those which lie scattered

along the crest and sides of the high ridge between Arlington and

Waverley.”

_Courtship._--William Brewster (1937a) writes: “On July 15, 1908,

I witnessed the coition of two Black-billed Cuckoos in woods near

Bethel, Maine. It took place on a branch only three or four feet

above the ground. Although performed listlessly and intermittently,

it was singularly protracted, for the two birds remained together

at least four or five minutes, and did not finally separate until

disturbed by my approach, when the male flew away and presently

sang once. The female stayed quietly on her perch until I got near

enough to see that she was a fully adult bird.”

_Nesting._--Most of the New England nests on which I have data were

placed at low elevations, 2 to 4 feet above ground, in various

small trees, bushes, or thickets. My first nest was the highest, 10

feet up, in the top of a leaning black birch in a strip of swampy

woods and brushy thickets along a small brook. Another was 8 feet

from the ground in a dense thicket of shrubbery and blackberry

vines. Three nests were in small white pines, 3 to 4 feet up, in

rather open spaces overgrown with various shrubs and small trees

near the edges of the woods; the nests were placed on horizontal

branches, against the trunk, and well concealed among the dense

branches. Near Asquam Lake in New Hampshire I saw two nests in

thick clumps of mountain-laurel in some dense and heavy deciduous

woods, where the land sloped down to the lake; the mountain-laurel

grew here in extensive patches, but not very high, seldom over 3 or

4 feet; the large and well-made nests were only 2 and 3 feet from

the ground, but fairly well concealed.

Some nests of the black-billed cuckoo are very flimsy affairs,

but often they are much more substantially built than the nests

of the yellow-billed cuckoo. Owen Durfee describes in his notes a

well-made nest that he found in a clump of chinquapin oaks near

a road in Rehoboth, Mass. It was made of oak twigs and dry fern

stalks, many of the twigs being fresh, with leaves attached; it

was lined with dry oak leaves and a few fresh ones. It measured 8

inches in outside diameter and 3 by 3½ inches in inside diameter,

being hollowed to a depth of 1 inch. There is a beautiful nest in

the Thayer collection, taken from a thicket in Lancaster, Mass.,

7 feet from the ground; it has a well-made foundation of coarse

twigs, tufts of grass, and burs; and it is profusely lined with the

green leaves and the cottony catkins of the poplar. S. F. Rathbun

writes to me of an interesting nest that he found: “The nest was

a saucer-shaped affair made entirely of the burs from the burdock

plant, simply stuck together so as to form a shallow receptacle for

the eggs. As a lining for the nest a few dry grasses were used, and

the burs with the grasses represented the entire structure. The

cuckoo certainly showed ingenuity when it made this nest, for it

could not have been more simply or easily constructed.”
