      > Hi All,
      >
      > As Helen notes, we just returned from a trip to the Divisadero/Creel/
      > Cerocahui/Urique area of Copper Canyon, where we searched the pine
      > forest not only for signs of the recently-reported Imperial
      > Woodpecker, but also for the workings of a large woodpecker.
      > (Elevations are above the range reported for Pale-billed and Lineated
      > Woodpeckers, though of course birds can wander out-of-range.)
      >
      > An exhaustive search of trees near Divisadero revealed no certain
      > workings of woodpeckers any larger than a flicker, and only one
      > instance of a potentially-larger bird at work. Those of you who live
      > near Pileateds know that their workings are obvious.
      >
      > The interesting fact remains that there have been reports of a very
      > large woodpecker over the past 5 years from locals in the Divisadero
      > area. The Mexican biologist who collected these reports had planned
      > to join us, but became ill at the last minute.
      >
      > Our feeling was that if the bird still survives, it will be in an
      > unpopulated area, far from humans. That is very hard to find in
      > Mexico. It was, after all, considered "un gran pedazo de carne" in a
      > protein-starved region.
      >
      > There were plenty of big snags in the forests, especially between
      > Cerocahui and Urique Rim, which were full of beetle larvae. Food did
      > not appear to be a limiting factor.

      > A quick look at a Steller's Jay in backlit conditions might confuse

      >
      > A very fun highlight was a flock of 30-35 Aztec Thrushes, streaming
      > up the cliff face at Urique Rim to feed on small black fruits of a
      > shrub. They were joined by Brown-backed Solitaires. Crescent-chested
      > Warblers and White-striped Woodcreeper were in the pines near the
      > Rim. Gray Silkies foraged at Divisadero.
