Trogon ambiguus

Gould

, 1835,

northern Mexico

.

Possibly most closely related to T. curucui, T. rufus, T. mexicanus, T. collaris and T. personatus; DNA studies suggest that T. rufus, T. collaris and T. personatus may be nearest relatives. Usually considered conspecific with T. elegans, although for long recognized as distinctive: differs in its finer-grained vermiculations on wingpanel (1); overall golden tone to green of breast, hindcrown and upperparts, the same gene presumably responsible also for uppertail being bronzy-coppery rather than yellowish blue-green (3); undertail pattern without close bold barring but instead with vague, incomplete vermiculations and with outer vane of outer rectrix all white, so that undertail looks almost entirely white (3). Populations in S Arizona and NW Mexico (excluding Tres Marías Is) sometimes separated as race canescens#R, but considered poorly differentiated. Two subspecies recognized.

    Status and conservation

    Not globally threatened. Common to fairly common in much of range; in N thought to fluctuate in numbers between years. In Mexico, very uncommon in Oaxaca, but generally... read more
