One morning last month, just before sunrise, the temperature plunged to -2 degrees. That's not so unusual for this time of year, but this particular morning brought with it one of my favorite winter phenomena: rime ice (also known as hoarfrost, ice fog, and rime frost). Every inch of every branch, stem and tree trunk, shimmered and glistened with a soft coating of white jagged ice.
It was a spectacular, foggy, winter wonderland against crisp blue skies. On some surfaces it was thick as snow while on others it appeared to be growing in sharp spikes.

Usually all I can see is a tail or two high up in the corner, but many nights one adult is sleeping separately from the group, alone on a ledge but tucked in against the weather. About two weeks ago, however, they stopped coming in to roost even though it is still windy and cold. Are these bluebirds winter birds who have since started their way north? Or are these the same bluebirds we have here in the summer? (will there be seven?) And if so, where ARE they right now? I miss their cheery songs and the promise of spring!
