Geographic Range
Tapera naevia
, commonly known as the striped cuckoo, is found from southern Mexico to southwestern
Ecuador, as well as in northern Argentina and southeastern Brazil.
- Biogeographic Regions
- nearctic
- neotropical
Habitat
Striped cuckoos occupy tropical habitats, which commonly include grasslands and scrub
forests from sea level to 1400 m in elevation. These birds are usually found near
the edge of forests, in areas with scattered shrubs and trees. Less commonly they
are round in tropical bogs.

Physical Description
Striped cuckoos are average sized cuckoos, with an average mass of 55 g, and approximately
30 cm in length. Average wingspan of males is 112.4 mm (range from 108 to 117.5 mm),
and of females is 108.2 mm (raange from 104 to 112 mm). Striped cuckoos have relatively
long tails, averaging 157.7 mm in males and 146.2 mm in females.
At hatching striped cuckoos are featherless, with pink skin and a yellow-orange gape.
Feathers are grown after approximately ten days. Immature striped cuckoos are characterized
by a black head, black markings on the neck, wavy black markings on the underside,
and yellow spots on the feathers of the upper body. Adults are overall brown in color,
and are distinguished by a shaggy crest and black streaks along the back. The feathers
of the adult's long tail are gray-brown and white tipped. The adult also has abnormally
large, dark alulas feathers (the alulas is a joint in the middle of the bird's wing),
giving it the common name "four-winged cuckoo." Adult females and males are nearly
identical in appearance.

- endothermic
- homoiothermic
- bilateral symmetry
- Sexual Dimorphism
- sexes alike
- male larger
Reproduction
There is little available information regarding reproduction in
Tapera naevia
and other cuckoo species. Striped cuckoos use songs to attract mates, in other cuckoo
species one female will mate "at random with males." Striped cuckoos are brood parasites
(neither males nor females provide parental care to offspring) suggesting that they
may be promiscuous.
- Mating System
- polygynandrous (promiscuous)
There is little available information regarding general reproductive behavior in
Tapera naevia
. Although records are limited, breeding and reproduction have been observed from
January until October, suggesting that striped cuckoos breed nearly year round. The
number of offspring produced each breeding season is unknown; however, other cuckoo
species produce approximately one to five eggs each breeding season. The incubation
period for striped cuckoo eggs is, on average, 15 days. The young are fledged and
leave the nest after 18 to 20 days.
Striped cuckoos are brood parasites; adult females lay their eggs in the nest of another
bird species. They lay their eggs just after dawn, and usually choose host species
with covered or dome shaped nests. The host species is "tricked" into caring extensively
for young that are not its own. Striped cuckoos have more than 20 documented host
species. They are obligate brood parasites, they do not build nests or incubate eggs.
After hatching, young
Tapera naevia
nestlings remain in the nest for approximately 18 to 20 days, after which they fledge.
- Key Reproductive Features
- iteroparous
- year-round breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual

Striped cuckoos are brood parasites; there is no post-egg laying parental investment.

Lifespan/Longevity
There is little available information regarding the lifespan striped cuckoos and other cuckoos.
Behavior
Striped cuckoos are solitary birds, active during the day. They tend to stay within
the cover of shrubs.
When frightened or disturbed, striped cuckoos will flash their alulas.
Home Range
There is little available information regarding the home range of Tapera naevia or other cuckoo species.
Communication and Perception
Striped cuckoos have three distinct song types. Each song type is used to communicate
with neighbors, mates, and intruders. Furthermore, each song type is used to communicate
its "readiness to interact" to its neighbor, mate, or intruder. One song is bisyllabic;
the second syllable has a higher pitch and is accented. Another song consists of five
to six syllables; the last syllable has a lower pitch that the first four to five.
A third song consists of four short syllables; again, the last syllable has a lower
pitch, and is much shorter, than the first three. Songs are whistled, and repeated
for minutes at five to ten second increments. During a song, striped cuckoos raise
and lower their crest, and may lower their wings. Songs are occasionally sung in duets
(commonly by mating birds), and striped cuckoos will respond to birds that imitate
their songs.
- Other Communication Modes
- duets
Food Habits
There is little available information regarding the food habits of striped cuckoos.
They eat insects (
Insecta
), mostly grasshoppers (
Orthoptera
). Other cuckoo species are omnivores, also eating insects, in addition to spiders
(
Araneae
), fruits, seeds, and even small vertebrates.
- Primary Diet
- carnivore
- Animal Foods
- insects
Predation
There is little available information regarding predation on striped cuckoos. When
striped cuckoos are frightened or disturbed, they will flash their alulas.
Ecosystem Roles
Striped cuckoos are interspecific brood parasites with over 20 host species, listed
below. The first 17 listed are well-documented hosts while the last four are probable
or minor hosts.
Striped cuckoo parasitism is believed to have a negative effect on both the nests
and fecundity of host species. In other cuckoo species, the young cuckoo will remove
the eggs of the host from the nest or kill the host's young, forcing the host to devote
its attention solely to the young cuckoo.

Economic Importance for Humans: Positive
There are no known positive effects of Tapera naevia on humans.
Economic Importance for Humans: Negative
There are no known adverse affects of Tapera naevia on humans.
Conservation Status
Tapera naevia
appears to be expanding its range, most likely in response to recent deforestation.
Other Comments
Cuckoos, in general, derive their name from the sound of their calls.
Tapera naevia
is the only cuckoo in its range with a striped back, and is therefore commonly called
the striped cuckoo.
