Sierra Nevada Red Fox sighting; And a Pygmy Right Whale in South Africa
SAN FRANCISCO — The first confirmed sighting of a rare Sierra Nevada red fox in Yosemite National Park in nearly a century has been confirmed by park officials.
Meanwhile I see from Trevor Hardaker on facebook that a Pygmy Right Whale has been spotted several times off of Cape Town in the past couple of days. So if anyone is in South Africa – or can get there fast – then go! This is by far the hardest baleen whale to see.
That really is impressive. The top level predator’s effects on an ecosystem is an ongoing narrative of a very broad thesis, very interesting to read about another example.
The wolf/moose/aspen/stream temperature/fish narrative is the classic example.
I thought the speculative idea that the Gray Squirrels were suffering from “fear” is plausible. Chronic stress is recognized as a causative factor in human disease, like metabolic syndrome.
My two pesos, FWIW.

Here’s a nice story on red and grey squirrels in the British Isles. I didn’t check it for accuracy. http://www.theguardian.com/environment/2015/jan/30/how-to-eradicate-grey-squirrels-without-firing-a-shot-pine-martens
