Description: Cactus Wrens (Campylorhynchus brunneicapillus)
are the largest wrens around Las Vegas. Most Cactus Wrens seem
to migrate out of our area during winter, but a few stay all year.
Cactus Wrens are interesting in that they use nests all
year for shelter, not just for rearing young. They build
covered nests in cholla cactus. It seems that the spines would
be a problem, but I guess it is more of a problem for nest predators
than it is for the birds. |
