Reading the guide allowed me to identify the bird as a gray-crowned rosy finch
, but it also got me interested in birdwatching.
Mountaintop birds like the rosy finch
of the Rockies, while they do not change latitudes, do drop to lower elevations before deep snow buries the world above timberline.
House finches, rosy finches
, English sparrows, Eastern and Western bluebirds and that ever-growing category, "linnets" - which seems to most people to include any small bird that can't be easily identified - can't get a whole grape in their beaks.
