Many people have deeply personal connections to the Robin. This popular keyhook design featuring the "When Robins appear, loved ones are near" saying reflects that. The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in the British Isles, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. About 12.5–14.0 cm (5.0–5.5 inches) in length, the male and female are similar in colouration, with an orange breast and face lined with grey, brown upper-parts and a whitish belly. The robin features prominently in British folklore and that of northwestern France, but much less so in other parts of Europe. It was held to be a storm-cloud bird and sacred to Thor, the god of thunder, in Norse mythology.
