Spilling Thought: This cute little guy is the American pika. 🐹 Research by @usgs has found that #pika populations are now disappearing from numerous mountainous areas and some populations are migrating to higher elevations. This is likely to avoid reduced snowpacks and warmer summer temperatures. Unfortunately, pikas are strongly tied to a habitat that is limited and patchily distributed, which gives them few options as temperatures continue to rise.
