I do not recognise the cane, but the overall design reminds me of William Manson's work from the 1979-1981 William Manson Paperweights / Scotia period, or 1981 onwards when he was at Caithness Glass.
However, in the William Manson catalogue entries shown in the books I have there is no exact match to a lone Robin on a branch. But there is a 1981 Willaim Manson Caithness Glass design of Robin + branch with flower head, surrounded by a single garland of canes that might be similar.
