Too southerly the phalarope

Birders (don't call them birdwatchers!) in California are spotting thousands of red phalaropes, which normally only land in the Arctic to reproduce. The article says that "scientists are stumped".

Well, given that some animals—including your cat—are known to navigate using the earth's magnetic field, perhaps it's related to the changing location of the magnetic pole?
