One of the highlights of this tour is visiting the Waved Albatross breeding colony on Espanola, where some birds nest within yards of the trail. Photo by participant Carolyn Pomarius.
Although the Galapagos Islands got one of their evocative names ("Las Islas Encantadas" or "The Enchanted Islands") back in sailing ship days due to the unpredictable currents between the islands, the almost magical tameness of the archipelago's wildlife means the name is still appropriate in the age of GPS units and motorized engines. On each of the islands we visited -- North Seymour, Floreana, Isabela, Fernandina, Santa Cruz, Espanola, San Cristobal and Genovesa -- we got "nose to nose" with the locals. We recorded most of the islands' endemic bird species, (the sole remaining location for the critically endangered Mangrove Finch is now sadly off-limits), with most of them seen very well indeed. And the extraordinary tameness of the various seabirds meant we had some magnificent encounters with them as well!
Among the chief highlights of a visit to the Galapagos are "Darwin's Finches," the unassuming little brown birds whose subtle differences helped Charles Darwin to crystallize his revolutionary theory of evolution. Now known to be drab members of the tanager family, these birds radiated out across the islands, changing subtly over the eons as they encountered new habitats and competitors. From our first (a mob of Medium Ground-Finches rummaging in the dirt near the airport terminal) to our last (a single Green Warbler-Finch that flicked through a nearby shrub), most proved satisfyingly cooperative. Who will soon forget the little swarm of Gray Warbler-Finches bouncing through the lava boulders on the Espanola beach? Or the 100-strong flock of Small and Medium ground-finches searching for seeds along the path at Whales Bay? Or the Woodpecker Finch carefully selecting and pruning its "poking sticks" -- and using those sticks to fish fat grubs out of woody burrows -- in the mangroves of Santa Cruz?
Of course, finches weren't the only birds that we saw well. Two Espanola Mockingbirds dogged our heels on Espanola. A gold-spangled Short-eared Owl preened on a low branch while its mate snoozed on a ledge nearby. Hot pink American Flamingos floated like fever-dream swans in a brackish pool. A pair of Galapagos Hawks tested their wings against the rising winds on Espanola, and an adult and youngster practiced a food handoff on Fernandina. Handsome Galapagos Doves trundled along path edges. And a handful of Floreana Mockingbirds sang from prickly pear cactus pads on Gardner Island. Blue-footed Boobies whistled and grunted and solemnly showed their amazingly hued feet to each other. Nazca Boobies huddled with fluffy "polar bear" chicks. Waved Albatrosses reunited with elaborate bill-clattering greetings, while their fluffy poodle chicks chirruped from ground nests. Storm-petrels accompanied our boat virtually everywhere we went, dipping and slicing over the waves in the open ocean and pattering on the surface in sheltered harbors -- with an Elliot's Storm-Petrel giving us exceptional "up close and personal" views when it landed between our tables during dinner one night. Flightless Cormorants panted on seaweed nests or dried nearly non-existent wings on the shorelines. Great and Magnificent frigatebirds puffed their enormous red throat pouches and clacked their bills and brooded fuzzy chicks.
But it wasn't all about the birds. There were also the lumbering Galapagos Tortoises, looking vaguely ET-ish as they munched on grass and leaves or wandered among the group. And the omnipresent Marine Iguanas, looking like tiny (and some not so tiny) dragons as they rested on rocks beside the sea. And the whip-fast Galapagos Sea Lions that played "chicken" with the snorkelers -- or rested like so many giant sausages on beaches throughout. Peter identified dozens of plants for us: daisy trees, and towering prickly pear cactus trees, and stubbornly tough little plants growing from seemingly dirtless cracks in vast lava fields. And each island's vistas proved enchanting.
Thanks to all of you for your good humor and camaraderie as we shared the adventures. It was great fun, and I hope to see you all in the field again some day!

BIRDS
These Galapagos Penguins certainly proved obliging, with one showing us its back, and the other its front. Photo by guide Megan Crewe.

MAMMALS

ADDITIONAL COMMENTS
In addition to the birds and mammals, the Galapagos has many other special animals. Here's what else we identified:
REPTILES
Espanola Snake (Philodryas biserialis hoodensis) - A tiny one lurked in the underbrush beside the trail on Espanola.
Marine Iguana (Amblyrhynchus cristatus) - A number of very distinctive subspecies, ranging from small and dark to large and colorful. The turquoise-limbed bright red male basking on the rocks on Espanola was particularly memorable.
Land Iguana (Conolophus subcristatus) - These big rusty red vegetarians were especially common on North Seymour and (appropriately) around Dragon Hills.
Lava Lizards: These were the smaller lizards seen on most islands -- including some standing on the heads or bodies of their larger Marine Iguana cousins. We saw four species, all but the one of which (the widespread Galapagos) were restricted to the island for which they are named:
Galapagos Lava Lizard (Microlophus albemarlensis)
Floreana Lava Lizard (Microlophus grayi)
Espanola Lava Lizard (Microlophus delanonis)
San Cristobal Lava Lizard (Microlophus bivittatus)
Galapagos Tortoise (Geochelone elephantopus) - Some taxonomists break out various populations as species, others as subspecies. We saw several forms, including those of Isabela and Santa Cruz.
Pacific Green Turtle (Chelonia mydas agassizi) - Lots of these huge sea turtles fed on seaweed below the ocean's surface, particularly between Isabel and Fernandina. The snorkelers, in particular, had some close encounters.
NOTABLE INVERTEBRATES
Sally Lightfoot Crab (Grapsus grapsus) - EVERYWHERE!
Semi-terrestrial Hermit Crab (Coenobita compressus) - A few roamed the beach or undergrowth at Bahia Urbina.
Ghost Crab (Ocypode gaudichaudii) - A handful of pink individuals lurked near their holes (and quickly disappeared at our approach) on the beach at Dragon Hills.
Queen (Danaus gilippus thersippus) - This big orange butterfly was seen on several islands.
Sulphur (Phoebis sennae marcellina) - As was this sizable yellow butterfly.
Large-tailed Skipper (Urbanus dorantes) - This endemic brown butterfly was seen only at Bahia Urbina, where it fed on trailside flowers.
Galapagos Blue (Leptodes parrhasioides) - These tiny, endemic, blue and brown butterflies were particularly common along the trail above Tagus Cove.
Amazon Darner (Anax amazili) - This was the green dragonfly with green and black striped abdomen that we saw at Dragon Hills on Santa Cruz.
Tawny Pennant (Brachymesia herbida) - The little gang of dragonflies we found sitting atop stems near one of the brackish pools at Punta Moreno were this species.
Tramea cophysa - This was the dragonfly with the mostly reddish abdomen with a black tip and a narrow stripe in the wing (along the body). It has no recognized common name!
Large Painted Locust (Schistocerca melanocera) - Especially nice views of one on the Dragon Hills walk.
Spotless Ladybug (Cyloneda sanguinea) - This was the small, unspotted ladybug we found on several islands.
Totals for the tour: 76 bird taxa and 7 mammal taxa
