For years we’ve hiked (carefully) past hundreds of stately cane chollas, many with what looks like wads of dried grasses caught tightly in and around the numerous spindly and haphazard arms that grow all over this desert cactus. On closer examination, we’ve discovered the cholla does not actually capture grasses blowing in the wind. Instead, an industrious and very chatty little bird collects great quantities of dried grass to build a football-sized cavity nest woven protectively and securely on and between the many arms of a cholla.
Meet the Cactus Wren.
Once you’ve heard this gregarious wren chatter and sputter hilariously, you’ll never forget it’s call! As we were walking along the trail one day, I instantly recognized a wildly vocalizing cactus wren. Scanning the skyline (because I know they also love rattling from a perch), he readily showed himself, and did not shy away as I approached. He was calling from the highest (10 feet) arm of a pretty stout cholla, and then quickly jumped down into the center of the branches to inspect an old nest.
This nest may have been old, but apparently this little guy felt a facelift was in order and began tidying up the tunnel-like entrance. He then collected a wad of grasses he’d plucked from the entrance and plunged himself down the tunnel, grasses included! What? What was this crazy bird doing …… nest building?
Turns out cactus wrens build several nests in the spring within their territory, and maintain them year-round. I have to believe they use their nests throughout the cold winter months to keep warm, and it looked like this guy was fixing up the interior of this particular nest with super soft bushmuhly grass stems. I would’ve loved an invitation to peek inside, but hiked on, leaving the cactus wren to his chores.
I’ve been by this nest several times in the past few weeks, hoping to catch the wren at home, but to no avail. Maybe he’s tending another nest somewhere else, as this one is in disarray.
The Sketch
My sketch, mostly from memory, was done all in graphite using the “subtractive” technique. I don’t usually sketch in his manner, because it can get quite messy ….. laying graphite down then using my mono zero eraser to create the image …. but it was an effective way to illustrate the complexity of the nest and so many cholla spines. Let me know what you think!
