Oreoscoptes montanus ye una ave paseriforme de tamañu medianu de la familia Mimidae, que tamién inclúi a los sinsontes, tembladores, y páxaros gatu. Ye l'únicu miembru del xéneru Oreoscoptes. Paez menos emparentáu colos cuitlacoches del Caribe, que colos sinsontes (Hunt et al. 2001, Barber et al. 2004).

Descripción[editar | editar la fonte]

Les partes inferiores de O. montanus son de tonu gris-marrón pálido, ente que'l so envés ye blancu con franxes escures. Tienen un picu delgáu rectu relativamente curtiu, güeyos mariellos y una cola llarga, anque non tanto como la cola d'otres especies de cuitlacoches.

Reproducción[editar | editar la fonte]

Esta ave reproduzse nel oeste d'América del Norte, dende'l sur de Canadá hasta'l norte d'Arizona y Nuevu Méxicu. El so hábitat de reproducción son zones con carbes d'artemisia y escasamente otres zones arbustives. La fema pon de 4 a 5 güevos nun nial en forma de taza construyíu con ramines y allugáu ente pacionales baxos. Dambos miembros de la pareya guaren y alimenten a los pichones.

Pel hibiernu, estes aves migren escontra'l sur d'Estaos Xuníos y Méxicu, incluyendo'l sur y norte de la península de Baxa California.

Alimentación y comportamientu[editar | editar la fonte]

Pel branu aliméntense d'inseutos; tamién comen bayes, especialmente pel hibiernu. Polo xeneral busquen inseutos nel suelu en zones con arbustos.

El machu entona una serie de gorjeos pa defender el territoriu nel que s'atopa'l nial.

La población d'estes aves menguó en delles zones onde se quitaron la artemisia pero entá son comunes naquelles zones en que'l so hábitat preferíu caltúvose. L'amenorgamientu de hábitats de artemisia nel oeste d'América del Norte ye motivu d'esmolición pa la esistencia d'esta y otres especies dependientes de la artemisia.
