Socorro Wren

Troglodytes sissonii

A relative of the familiar House Wren, this bird is only found on the island of Socorro, in the Mexican the Revillagigedo Islands. Science first discovered the Socorro Wren when Andrew Jackson Grayson found the bird in 1865. There was over a century of disagreement about how to classify the genus for this species (Troglodytes or Thryomanes), but as is the way currently king in the world of scientific classification, DNA studies have concluded that the Troglodytes handle is the most appropriate.

I met these birds while accompanying a science team on an nineteen day expedition aboard the Shogun out of San Diego in February 2017. We visited several of the remote volcanic islands 600 miles off the coast of mainland Mexico. Along with master birders Amy McAndrews and Jorge Montejo, I concentrated on the bird-life we encountered, while the rest of the team studied the plants, reptiles, insects and other life-forms.
