Elliot's (White-vented) Storm-Petrel - Oceanites gracilis |
The main reason for our trip to South America was a voyage scheduled from
23rd October to 16th November 2017 on
Yacht Sauvage.
Kirk Zufelt initiated and organised the trip. The attraction of eastern pacific seabirds framed between two exotic locations was irresistible to us.
Start: Port of Arica, north Chile
End: Puerto Ayora, Santa Cruz, Galapagos (Ecuador)
Our other companions were:
|
Inca Tern - Larosterna inca |
|
BIF practice from the deck |
|
Peruvian Pelican - Pelecanus thagus
|
While still in Arica Port we practised photographing Inca terns and - more easily - Peruvian Pelicans while we waited for the Chilean Immigration officials to chop our passports “Departed”.
|
El Morro, Arica |
Exit formalities done, we had a fine view of the flag above “El Morro” lookout as we sailed away.
We saw Peruvian Boobies, Peruvian Diving Petrel and the very localised Peruvian Tern.
|
Peruvian Booby - Sula variegata |
|
Peruvian Diving Petrel - Pelecanoides garnoti |
|
Peruvian Tern - Sterna lorata |
In late afternoon, about 12km from the coast, we came across a decaying sea lion carcass, attended by a flock of 25-30 Storm-Petrels (mostly Elliot’s but with a few Wilson’s among them).
A single Northern Giant Petrel exemplified some extremes of tubenose size.
We drifted around near the Storm-Petrels, trying to get shots that didn’t show too much dead sea lion. An alien presence was noted in the air - a Peregrine. It swooped towards us and took one of the SPs from the surface of the water.
The Peregrine was so quick that that the other birds didn’t seem to notice that one of their number was missing.
And, forty minutes later, in the fading light, the Peregrine did it again.
We were 30km offshore at dawn the following day. Overcast and cool, the effect of the cold-water Humboldt current was keenly felt. We had first views of Markham’s Storm-petrels and made our first sightings of Swallow-tailed Gulls as well as many Sooty Shearwaters.
|
Sooty Shearwater - Puffinus griseus |
|
Markham's Storm-Petrel - Oceanodroma markhami |
Temperatures on board were cool but comfortable, and we all settled into spending lots of time on deck.
|
Cockpit of Yacht Sauvage |
|
Pink-footed Shearwater -Puffinus creatopus |
Morning fog cleared around midday, a weather pattern often repeated during the trip.
|
Swallow-tailed Gull - Creagrus furcatus |
|
Markham's Storm-Petrel - Oceanodroma markhami |
|
Markham's Storm-Petrel - Oceanodroma markhami |
There were terns, including Elegant, South American, Inca and Black, with regular appearances of jaegers to harry them. (As we were in he Americas I’ve used “jaeger” rather than “skua” in the photo captions).
|
Long-tailed Jaeger - Stercorarius longicaudus |
|
South American Tern - Sterna hirundinacea |
|
Elegant Tern - Sterna elegans |
|
Elegant Tern and Pomarine Jaeger |
A daytime drip of menhaden fish oil meant that we were never without a following of Storm-Petrels in the wake of the Sauvage, but which Storm-Petrel species were there did vary as the route progressed. We started out with mostly Elliot's but later there were more Wedge-rumped.
Hornbys (Ringed) Storm-petrels were encountered, but these never followed the boat.
|
Hornby's Storm-Petrel - Oceanodroma hornbyi |
|
Hornby's Storm-Petrel - Oceanodroma hornbyi |
Early in the trip, we found that off southern Peru there were some expected southern ocean seabirds, including Black-browed and Bullers Albatrosses.
|
Buller's Albatross - Thalassarche bulleri |
There were White-chinned Petrels showing varyingly small amounts of white chin.
|
White-chinned Petrel - Procellaria aequinoctialis |
Of closer origin (islands off the mid-Chilean coast) we saw a few De Filippi’s (Masatierra) Petrels, our first pterodromas of the trip.
|
De Filippi's Petrel - Pterodroma defilippiana |
|
De Filippi's Petrel - Pterodroma defilippiana |
Black Storm-Petrels were noted
|
Black Storm-Petrel - Oceanodroma melania |
and it was often the more wave-hugging flight pattern that distinguished their silhouettes from Markham’s.
|
Markham's Storm-Petrel - Oceanodroma markhami |
|
Wedge-rumped Storm-Petrel - Oceanodroma tethys |
We navigated toward seamounts with varying degrees of success.
|
Hawksbill sea turtle - (Eretmochelys imbricata) |
Large ships are always a hazard to navigation, but the presence of many Peruvian fishing boats on part of our route provided another reason for the ever-vigilant Didier to be careful.
Eight days into our journey we had our first views of Waved Albatross, famously a breeding endemic of Espanola in the Galapagos, but they breed on Isla de la Plata near Guayaquil in mainland Ecuador, too.
|
Waved Albatross - Phoebastria irrorata |
At the end of every busy day, everyone settled down in the cabin to edit their shots.
Some nights we found we had a following of Swallow-tailed gulls. Nocturnal hunters of squid, these birds have a bat-like rattling contact call.
|
Swallow-tailed Gull - Creagrus furcatus |
This shot was taken with a high ISO and thanks to Kirk Z. for the torch work.
|
Short-beaked Common Dolphin - Delphinus delphis |
A large pod of Short-beaked Common Dolphins provided some mid-voyage entertainment.
