September 9-12, 2019 The Pribilofs: St. Paul Island


Our WINGS guides, and half of the birders were stranded on Saint Lawrence Island on Saturday, due to the weather, and so didn’t make the Sunday flight out to the Pribilofs.

Luckily, WINGS had made arrangements for the ‘local’ guides to lead us on this amazing tour.

Monday the 9th was a day just for the 5 of us ‘tourists’ to be birding with Sulli Gibson and Alex Harper from Saint Paul Island Tour, which is fully owned by TDX Corporation, the Alaska Native Corporation.

The Pribilofs are the remainders of what was once part of the Bering Land Bridge before the melting of the glaciers.  The current wind-swept tundra was once home to woolly mammoths.
I didn't take this shot; it's from the Hulton Archives
Research indicates that these Holocene elephants likely overgrazed their habitat when rising sea levels reduced the size of the island around 5,600 years ago, or about the time that the Minoan Culture was developing.

Looking across the putchki, it is not hard to imagine a herd feeding its way across the tundra landscape.  Among all of the Bering Sea islands, St. Paul Island is unique in having lava tube caves from which animal bones might be collected.  One such lava tube on Bogoslof Hill yielded mammoth teeth, as well as polar bear remains.  In 1999, researchers found even more “fossils” of woolly mammoth, polar bear, caribou, and Arctic fox in Qagnax̂ cave on Saint Paul.
 
Smithsonian paleobiologist Clayton Ray, in a 1971 article, noted that one of the local managers for the Alaska Commercial Company, a Mr. J.C. Redpath, had faked finding some mammoth tusks on Saint Paul, ostensibly as a practical joke.  This same Mr. Redpath also salted the black sands of Lunakin Beach with smelted droplets of bronze to mimic gold!  Quite the prankster . . . and likely hoping for a profit in it all.   However, the other mammoth bones found on the Pribilofs were apparently authentic.

Besides mammoths, the only land mammals originally on the islands in pre-history were arctic foxes, shrews, and polar bears.  In the late 1800s and early 1900s, polar bear arrived in conjunction with the ice pack.  They were last recorded on St. George Island in 1915: “The men report seeing bear tracks near the Company House at Zapadni… They lead from the sea line to a place where the animal had apparently laid down and again to where it again took to the water.”

There are still ungulates on Saint Paul now, however.  In the fall of 1911, the U.S. government imported 25 Siberian Reindeer to the islands to provide the resident Aleut (Unangan) with a source of fresh meat.  By 1921, the population had grown to 250 animals, and by 1938, there were about 2,000 reindeer on St. Paul Island.  Poaching, harsh winter weather and starvation resulting from overgrazing severely depleted the St. Paul herd in the 1940s.

In 1950, only eight reindeer remained on St. Paul Island, so in 1951, 31 reindeer were brought to the island from Nunivak Island.  Currently, several hundred reindeer roam St. Paul Island.  Interestingly, when the reindeer population exploded in the 1930s, they depleted the lichens, and changed the vegetative make-up of the island.  The Saint Paul reindeer are now thriving by grazing the grass and putchki, rather than lichens, and currently number around 400 animals, which the Native Corporation manages.

At one point, we saw a herd of these animals milling in a tight circle near the road.  We pulled up behind a pickup where a local was viewing the reindeer through a spotting scope.

We waited a bit, not wishing to spook the deer.  Then, seeing that the reindeer were not paying much attention to us, got out for better looks and photographs.  At that point, there was the roar of a .30-06 from the pickup ahead of us.  A few of the birders were horrified; “Oh, My God!  Is he killing those beautiful animals?!!!”  But some folks assured them that the Aleut was “just trying to scare the deer away from the road”…  A second shot was made, so we herded the birders into the van and drove away.  I am always surprised to meet people who don’t know where food comes from.

Off and on, we’d turn over a board or stray plank of plywood, hoping to get a view of the endemic and Endangered Pribilof Island Shrew Sorex pribilofensis, but to no avail.

Arctic Foxes were seen pretty regularly, mostly near the village.

 Normally the species is a beautiful snowy white in winter, and on account of its abundance and wide range it does not command a high price on the fur market.

But on these and a few other islands, the melanistic strain predominates and the slate colored pelts are called “blue” in the fur markets.  Because of their relative scarcity they commanded a higher price than the white.

We were told that we shouldn’t feed the foxes, as the Native Corporation had forbidden that activity.  However, we often watched a native Elder come out to feed these charming little animals.

The mammals that are most obvious on Saint Paul - besides the humans - are the Fur Seals.


The reason that there are people on Saint Paul in the first place is because Russian sealers imported Aleuts to do the heavy labor of harvesting pelts.
The Pribilofs were uninhabited, and were discovered in 1786 by Russian fur traders.  They landed first on St. George, and named the larger island to the north St. Peter and St. Paul Island.

In 1788, the Russian American Company enslaved and relocated Aleuts from Siberia, Atka and Unalaska to the Pribilofs to hunt fur seals; their descendants live on the two islands today.
1983 Book by Barbara Boyle Torrey
The Pribilof Fur Seal Monument commemorates the 100th anniversary of the signing of the North Pacific Fur Seal Treaty of 1911.  This treaty was an international treaty designed to manage the harvest of the fur seals, and prohibit the killing of fur seals in International waters.

Northern fur seals are "eared seals", who spend most of the year in the ocean.  Weaned pups typically spend nearly 2 years away before returning to their breeding colonies.  Fur seals use the open ocean for foraging and return to the rocky beaches for resting, molting, and reproduction.

After the U.S. acquired the islands during the Alaska Purchase in 1867, the Federal government licensed the Alaska Commercial Company for 20 years, then the North American Company for another 20 years to harvest the seals on Saint Paul, with an exclusive control over the harvest and the residents.

Life for the Unangan was little better under the American monopoly than it was under the Russians.  Then, the government assumed sole management of the commercial harvest until 1984.

In that year, the fur seals were designated as a “depleted stock” under the Marine Mammal Protection Act, because the stock had declined by more than 50 percent from its estimated population of 2.1 million seals in the 1950s.

 It was not until 1966 that the Aleuts were freed from their servitude to the U.S. Government by the passage of the Fur Seal Act.  This law forbade the killing of fur seals in the Pribilofs, with the exception of subsistence hunting by Alaska Natives.  The termination of the fur seal trade meant the end of Aleut slavery.

Saint Paul has a population of about 500 souls, mostly Unangan
The subsistence harvest is currently managed under a cooperative management agreement between the Pribilofs Unangan Government and the National Oceanic and Atmospheric Administration.

According to NOAA, the 2017 abundance estimate for the eastern Pacific stock was 620,660 northern fur seals.

The Saints Peter and Paul Church was founded in 1830, and the current church was built in 1905.  The bell tower from the “old church” was removed, and apparently not reinstalled until after 1989.  Their website tells us that most of the worship services are done in English, although they use Church Slavonic and Aleut at times.

The vegetation on the island is predominantly the putchki or wild celery (Angelica lucida), beach rye (Elymus arenarius), Nootka lupine (Lupinus nootkatensis) and Pacific hemlock-parsley (Conioselinum chinense).

It being September, most of the wildflowers were done blooming, but there were a few.

There are no trees native to the islands; the nearest things being the dwarfed willows.

 . . . isn't all that tall.  That's my foot!
The guides showed us the “Pribilof National Forest”, which consists of a planting of Sitka Spruce near the old Coast Guard Loran Station.  Loran was the hyperbolic radio navigation system developed in the United States during World War II, and the guidance system that mariners and aviators relied on for years - until President Obama declared the system obsolete in 2009, at which time it had been replaced by the current GPS system.  These trees are about 3 or 4 feet high and are likely 30 years old.

With this exotic and amazing landscape before me, I can’t wait to go birding!
