Santa Cruz—the highlands

Located near El Chato Giant Tortoise ReserveRanchoElManzanillo, Rancho El Manzanillo offers a lovely open-air dining area (below), where we had a delicious lunch.  “Manzanillo” is the name of the small apple-like fruit that grows on the trees in the area.  Mazanillos are poisonous to humans—not just the fruit but the sap can cause blistering too.  But the tortoises eat them with no problems.  While we were eating, Carolina chatted with the owner to find out what might be going on with the tortoises.  We learned later that an international group of tortoise researchers were having lunch at the next table over from us.

ElManazillo_diningAfter lunch, we headed out to walk the grounds.  Our first species were the most GroundFinchescommon of the 13 species of “Darwin’s finches”—Ground Finches feeding on the eponymous ground.  The Ground Finches are notoriously difficult to tell apart; since these were feeding as a group, we can probably rule out Large Ground Finches.  Most likely, they were Medium or Small Ground Finches, given the GalapagosLakelocation.  At Galápagos Lake, we spotted a Galápagos (White-cheeked) Pintail (below left) bathing amidst the red pond vegetation.WhitecheekedDuck  (Yes, that is water!)  Note that the word “poza”  on the sign implies a puddle or a backwater. The Galápagos Pintail is a subspecies of the Bahama (White-cheeked) Pintail SmoothbilledAniand in the same genus as the Northern Pintail, familiar to us in the U.S.  A Smooth-billed Ani—an unbelievably successful invasive, non-native species first introduced in the archipelago in the 1970s—watched us from above (right).  And a rather scruffy Galápagos Mockingbird—the most widespread of 4 endemic species of mockingbird in the archipelago—followed us curiously as we headed down the trail (below).

And perhaps only a wildlife rehab person would care—but I asked Zell to take a photo of the tortoise poop that we found on the trail.  We don’t have anything in the photo for scale, but this particular specimen was probably 5 or 6 inches long.

TortoisePoopYou’re welcome.

Back at the dining area, we pulled sticky seeds off our pants and shoes— don’t want to risk spreading Santa Cruz seeds to another island.  They seemed to attach better to nylon than to denim.  Folks wearing jeans had a much less tedious task.  We also had some wonderfully refreshing cold lemongrass tea.  We climbed back on board our bus and headed down to Puerto Ayora.
