Habitat loss and probably over-hunting at the turn of the century contributed to the marked decline of this fox squirrel subspecies, which was listed as endangered in 1967.
High in the rocky slopes of Glacier National Park lives a fuzzy, potato-sized animal called the North American pika (Ochotona princeps). The pika is a lagomorph, in the same order as rabbits and hares, and they are experts at cold-climate survival. Pika live year-round at high elevations without hibernating. Their thick coats and high metabolism allow them to keep their body temperature at 104°F all year long. To support this metabolism through the winter, pika must spend the entire summer stockpiling food in caches known as haypiles.
When hiking in the alpine in Glacier National Park you’ll often hear the distinctive “EEK!” call of the pika. Look for a small, compact mammal with round ears and a short tail. In the summer pika are usually seen with a mouthful of vegetation, running to a haypile where the food will be stored for winter. Glacier is thought to be home to between 1,800 and 3,600 pika.
The extreme cold habitat that the pika is adapted to is disappearing due to climate change. Their high body temperatures make pika very susceptible to heat stress. To avoid this, on hot days pika must spend more time under the rocks cooling off and forgo some of their foraging opportunities. Too many hot days and the pika will not have enough food to last the winter.
Since 2008, the Glacier National Park Citizen Science Program has organized pika surveys, conducted by volunteers, to observe any changes in pika distribution and population. The data collected has shown, on average, a decrease in pika occupancy in the 46 sites surveyed. Similar surveys are also done at eight other National Parks to find broad trends in pika well-being. By working together across different parks, with scientists and the public, and with park staff and visitors, we can still save one of the most adorable and extreme members of our ecosystem.

The Perseid meteor shower, one of the biggest meteor showers of the year, will be at its brightest early in the morning on Wednesday, August 12. Read on for some tips on how to watch the night sky this week – and to find out: what exactly are the Perseids, anyway?

Your best chance to spot the Perseids will be between 2 AM and dawn (local time) the morning of August 12. Find a dark spot, avoid bright lights (yes, that includes your phone) and get acclimated to the night sky.
Your eyes should be at peak viewing capacity after about 30 minutes; though the Moon may block out some of the dimmer meteors, you should still be able to see up to 15-20 an hour. If you’re not an early bird, you can try and take a look soon after sunset (around 9 PM) on the 11th, though you may not see as many Perseids then.

If it’s too cloudy, or too bright, to go skywatching where you are, you can try again Wednesday or Thursday night – or just stay indoors and watch the Perseids online!
Our Meteor Watch program will be livestreaming the Perseids from Huntsville, Alabama on Facebook (weather permitting), starting around 9 p.m. EDT on August 11 and continuing through sunrise.
So… why are they called the Perseids?
Because all of a meteor shower’s meteors have similar orbits, they appear to come from the same place in the sky – a point called the radiant.
The radiant for the Perseids, as you might guess from the name, is in the constellation Perseus, found near Aries and Taurus in the night sky.
But they’re not actually coming from Perseus, right?

Right! The Perseids are actually fragments of the comet Swift-Tuttle, which orbits within our solar system.
