A splash of gold

As temperatures plummeted to -4°C, the landscape was enveloped in freezing fog and adorned with hoar frost, creating an eerily beautiful, silent world. Most of the birds seemed to be conserving their energy, keeping a low profile amidst the biting cold. It was a day when nature appeared to be in suspended animation, each element cloaked in a stark, frosty stillness.

To my surprise, amidst this frigid tranquility, a small group of goldfinches emerged, flitting about energetically and feasting on seed pods. Their vibrant plumage created a striking contrast against the pale fog, a joyous splash of color in an otherwise monochromatic scene. The sight was nothing short of magical—an unexpected burst of life and warmth in the frosty expanse.

Capturing this moment was a profound reminder of nature’s resilience and beauty, even in the harshest conditions. The goldfinches, with their cheerful movements and bright hues, brought a sense of hope and wonder to the frozen landscape, making it a truly special experience to witness and photograph.

How does hoar frost form?

Ground frost forms when the air is still and cold, usually on clear winter nights. Water vapour in the air condenses on solid surfaces, and as the surface temperature drops below 0°C, ice crystals form.

Hoar frost requires slightly different conditions. It forms when the water vapour in the air comes into contact with solid surfaces that are already below freezing point. Ice crystals form immediately, and the ice continues to grow as more water vapour is frozen. On a still night, it can grow well on tree branches, where the surface temperature is unlikely to rise above zero for several hours.
