reyezuelo de los cactus

1. Nombre del ave
English name: Cactus Wren
Scientific (Latin) name: Campylorhynchus brunneicapillus

2. Aspecto
The Cactus Wren is a sizable wren, stealing the show with its distinct coat of black and white colors. The upper body of the Cactus Wren is covered with black, white and brown feathers that make a rough pattern, and its underparts are shades of white and brown. It displays a bold white stripe over each eye, enhancing its appeal. Its beak is long and curved, perfectly adapted for reaching into cactus in search of food. Both genders have the same overall characteristics, making it difficult to tell them apart.

3. Tamaño
This large wren averages in length from 18 to 23 centimeters (7–9 inches). Although wingspan can differ, the average is between 27 and 32 centimeters (10.5–12.5 inches). Weight ranges between 32 and 47 grams (1.1–1.6 oz).

4. Hábitat y distribución
The Cactus Wren is generally discovered in arid and semi-arid regions of southern United States, Mexico, and Central America. It particularly prefers habitats characterized by thorny shrubs and cacti, and hence its name. From coastal sage scrub to desert lowlands, it thrives in a variety of harsh conditions.

5. Datos de interés
The Cactus Wren has a unique nesting habit. They construct their nests in cactus plants or thorny trees to protect against predators and harsh weather. Additionally, unlike many other birds, Cactus Wrens regularly build new nests for raising each brood. Another fascinating fact is that they seek refuge in the same cactus where they build their nests, and they too eat and distribute the seeds of these cacti, playing a crucial role in the propagation of new plants.

6. Dieta
These birds have an omnivorous diet, which includes a variety of insects, spiders, and other small invertebrates. They also consume fruit and seeds, particularly those of cacti. Occasionally, they will scavenge for carrion.

7. Comportamiento y sonidos
These birds are not migratory and tend to stay in their territories throughout the year. Their call is often described as erratic and harsh, somewhat resembling a car engine failing to start.

8. Estado de conservación
According to IUCN Red List, the conservation status of the Cactus Wren is relatively stable, classified as of “Least Concern”. However, in some regions, their population is declining due to urban sprawl and agriculture.

9. Vida útil
The typical lifespan of a Cactus Wren in the wild is up to 10 years. However, in captivity, they may live slightly longer, perhaps up to 15 years.

10. Notas adicionales
In Mexico, the Cactus Wren is often called “Cholino”. Because of their impressive survival skills and adaptiveness in harsh environments, they hold a special cultural significance amongst the indigenous communities inhabiting the desert regions of America. By spreading cactus seeds, these birds contribute to the stabilization of vulnerable desert ecosystems. Depression of their population could lead to considerable changes in the delicate balance of these ecosystems.
