Field Trip: Galápagos Animalia -- Santa Cruz, Santa Fe, and Plazas Norte


Photos of flora and fauna from a week in the Galápagos -- the islands of Santa Cruz, Santa Fe, and Plazas Norte.  Notes accompany photos, though the pictures themselves look better in slide-show format.  Click on any photo to kickstart the slide-show.  Enjoy!

Cactus Finch feeding
Medium Ground-finch (most likely!), with courtship display
Galapagos Mockingbird
Marine Iguana
Black-winged Stilt
Whimbrel


Spiny Galapagos Tree-slug -- not the official name, just a guess
Fishing Lava Heron
...with his catch

Galapagos Tortoise, from the Charles Darwin Research Center


Prickly Pear Cactus tree -- food and shade for the endemic land tortoises
Baby tortoise
Smooth-billed Ani
Pair of Galapagos Mockingbirds
Yellow Warbler -- the Galapagos variety lacks the red streaking of the North American kind, it's the only warbler on the archipelago.
Galapagos lava lizard, male displaying
Lava Gull
Spotted Manta?
Black-winged Stilt
Lava Gull
Magnificent Frigatebird
White-vented or Eliot's Storm-petrel
Sea lion, or lobo (wolf) in Spanish -- to me, the canine name is much better.  Sea-lions are the Labs of the sea.
Playing with string... another couple was playing with a crab.  Most are juveniles playing in a protected inlet while the "beach master" male patrols, on the lookout for Galapagos sharks.  In a fight between an adult sea lion and Galapagos shark, I'd give it to the sea-lion 9 out of 10 times, said Eddy, our guide.



Swallow-tailed Gull on Plazas Norte, nesting
Galapagos Land Iguana


No tail?  No dice.  This iguana obviously didn't make it.  Sometimes the sea lions nip them off, or they may lose one fighting with a rival male.
Cactus flower
Blue-footed Booby
Brown Noddy, or Noddy Tern
Galapagos Shearwater, actually a member of the Puffin family
Red-billed Tropic-bird
Nesting Noddies
Pile of Marine Iguanas -- the one in the center is not climbing; he's just hanging out like that.


Limited shade, lobo and iguana share it
Cactus Finch -- the ID is in the shape of the beak, it's one of the easier of Darwin's Finches to ID.
Swallow-tailed gull eggshell



Nursing sea lion

Just off shore you could see the 10' Galapagos Sharks patrolling the bay, waiting for a hapless juvenile to wander too far out.  There has been one surfer fatality in the last year (off the Island of Santa Cruz) due to the Galapagos Shark.

Riptide warning on a popular surf beach with a Brown Pelican

Endemic, the Galapagos Flycatcher
Cattle Egrets
Don't know what kind of crab this is, but we called it the strong-arm.  Only the right claw is big (and red).
Ruddy Turnstone

Stilt

White-cheeked pintail
Snowy Egret


Likely Medium Ground-finches -- it's said that "only God and Peter Grant can identify Darwin's Finches."  The beak and body-sizes of some, including the medium and large, overlap.
Returning to Puerto Ayora
The island of Daphne Major -- famous site for evolutionary biology as the Grant team has studied the variations and observable evolution of its finches for generations, since 1971.
