Why would a sooty shearwater be so far inland?

Answered by ScottShaffer

Question from chris:

I live in central New York, Fulton County to be exact, and I saw a large black bird at work. It seemed to be distressed as it landed in the parking lot and weakly hobbled around. It then made an attempt to fly and went about 75 yards and slammed into the side of our building. It sat on the ground for about 10 minutes after that, got up, walked a few feet, then flew away. I came home and did some research on the internet because I was not sure what kind of bird it was and after surfing around I came to the conclusion it was a sooty shearwater.

How do elephant seals avoid white sharks?

Answered by DanielCosta

Question from Prasad Siripuram:

On TV we see the great white shark attack unsuspecting sea lions from below. If the sea lion pares off the initial attack, it generally outmaneuvers the shark. An elephant seal, on the other hand, doesn't have the swimming agility of a sea lion or a great bite power to thwart off a great white shark. Going by this logic, a great white can pick off an elephant seal anywhere at the depth or at the surface and the poor seal doesn't seem to have a chance.

Is it possible the "shark cafe" is an area where the earth's magnetic field is stronger?

Answered by KevinWeng

Question from Aaron McQueen:

I listened to Quirks and Quarks on CBC radio today where Dr. Barbara Block spoke about the "shark cafe" as a point about halfway between California and Hawaii where great white sharks congregate. She said they dive down very deep and it's not known for sure what attracts them to this isolated spot. I remember hearing on another episode of Quirks and Quarks about a study that showed that crabs can navigate their way to their "home" using receptors that are sensitive to the earth's magnetic field.
