long-tailed jaeger

 


Long-tailed jaeger, Aug 9, 2018, Burlington, Ontario, Canada.

For several kinds of Arctic predators, including Snowy Owls and Arctic foxes, lemming populations can make the difference between survival and starvation. But Long-tailed Jaegers are long-lived and eat lemmings only in the summertime; they forage at sea in the winter. This means they can avoid lemming shortages simply by choosing not to breed, a strategy that has been likened to “skimming the cream” off the lemming’s population cycles.

Now I don’t normally take a camera into the bathroom, however, this is regular thing with Maggie so, now you know the story. Sam, the black cat wants to know what Maggie is doing. Sam seemed quite upset over the blow to feline superiority.
